If you’re in the market for a new furnace, it’s a good idea to know about AFUE ratings. AFUE stands for annual fuel utilization efficiency and is a rating that determines a heating system’s efficiency. Here’s what you need to know.


AFUE ratings are measured in percentage. They indicate how much of your furnace’s fuel is converted into heat to warm your home. Consequently, a furnace with a high AFUE rating is more efficient than a furnace with a low rating. For example, a furnace with an AFUE rating of 85 converts 85 per cent of its fuel (natural gas, electricity, or oil) into heat and only wastes 15 per cent.

You can find your furnace’s AFUE rating next to its British thermal unit (BTU) rating, which measures the unit’s heating power. For instance, a furnace with 80,000 BTUs is large enough to heat a 1,600 square foot home. However, a system with 80,000 BTUs and an AFUE rating of 90 per cent only delivers 72,000 BTUs of heat to your home.

Minimum AFUE ratings in Canada

AFUE ratings typically range between 80 and 100. However, the Canadian government recently updated its regulations. Consequently, any furnace manufactured since July 2019 must have a minimum AFUE rating of 95 per cent. In the United States, the minimum AFUE is 80 per cent.

AFUE and your energy bills

A furnace with a high AFUE rating can have a dramatic impact on your energy costs. If you have a furnace that’s 15 to 20 years old, it probably has an AFUE rating of around 80 per cent. However, furnaces become less efficient as they age. Therefore, if you have an old heating unit, it’s likely not as efficient as its AFUE rating indicates. Consequently, replacing your existing furnace with one that has a high AFUE rating could significantly reduce your energy bill.

Features of high AFUE furnaces

Manufacturers use new technology to make their furnaces more efficient. Here are some of the features of high AFUE-rated furnaces.

  • Secondary heat exchanger
  • Variable speed blowers
  • Variable heat output
  • Direct spark or hot surface ignition systems to replace pilot lights
  • Improved filter systems

Your thermostat is a vital piece of your home’s heating and cooling system. It regulates the temperature in your home by telling the HVAC units to turn on or off at certain times. Here’s why the location of your thermostat is just as important as what type of thermostat you buy.

How your thermostat works

Thermostats track temperature changes in the air. Basic models use two strips of metal that expand or contract with temperature changes. However, modern, smart thermostats use electronic sensors to gauge the ambient temperature.

Regardless of the type, all thermostats measure the temperature in the air in their immediate vicinity. Consequently, a thermostat in your living room can’t regulate the temperature in your bedroom. Therefore, it’s best to locate your thermostat in an area where you spend most of your time.

Locations to avoid

If your thermostat is in an unsuitable location, it won’t accurately read the temperature in the air and could make your HVAC system run too often or not enough. Consequently, some rooms may become too cold, and some too warm. Here are some tips for finding the best location for your thermostat:

  • Stay away from exterior walls and floors. Place your thermostat on an interior wall at least 45 centimetres from an exterior wall and at least 1.5 metres off the floor.
  • Locate your thermostat well away from hot water pipes, fireplaces and air vents.
  • Avoid locating your thermostat near windows and doors, as drafts can result in skewed readings.
  • Keep your thermostat out of direct sunlight. This can fool your thermostat into thinking it’s warmer than it is. Therefore, it may make your air conditioning system run more often.
  • Avoid placing your thermostat in drafty stairways or areas with poor air circulation.
  • Keep furniture, houseplants and other obstacles away from your thermostat.

Ideally, your thermostat should be placed near the centre of your home.

Upgrading your thermostat

On top of correctly placing your thermostat, you may want to consider upgrading to a smart model to improve the efficiency and comfort of your home.

Smart thermostats offer precise control over your home’s air temperature. You can program them to run less often at night or when you’re not home. You can also control your thermostat with your smartphone. For example, you can warm or cool your home while you’re commuting to and from work or school.

Moreover, modern HVAC systems often have a zoning feature, which allows you to control the temperature in different areas of your home. Fortunately, it’s easy to retrofit your existing system with this feature.

Regularly maintaining your HVAC system helps prevent costly repairs and replacements. In today’s hectic world, it’s easy to forget to book a maintenance call, especially if you don’t notice any problems. That’s why it helps to sign up for an annual maintenance plan with Harmony Heating & Air Conditioning. Here’s a look at everything you need to know.

How HVAC maintenance plans work
When you sign up for an HVAC maintenance plan, you shift the responsibility for scheduling an annual service call to a professional heating and cooling company. By paying a monthly or annual fee, you get a yearly tune-up on all your HVAC equipment, as well as other perks like discounts on repairs and front-of-the-line priority service. The company keeps track of your maintenance and schedule, so you don’t have to.

Despite the fees, a maintenance plan can save you money down the road. For example, your HVAC equipment will run at peak efficiency, reducing your energy bills. Also, during your annual inspection, the HVAC technician can spot and repair minor problems before they become major issues that require expensive repairs or replacement.

Residential HVAC maintenance plans
Every homeowner can benefit from an HVAC maintenance plan. However, if your home’s heating or cooling system is nearing the end of its life, you may want to consider replacing your air conditioning or heating system rather than investing in a maintenance plan.

However, if your HVAC equipment is still covered by the manufacturer’s warranty, then signing up for a maintenance plan is a good idea. Warranties often only cover the cost of replacing a part, not the labour involved. In addition, manufacturer warranties don’t cover the cost of the regular professional maintenance required to keep it valid.

Of course, if your warranty has expired, it’s even more crucial to maintain your equipment because you’ll be on the hook for any expensive repairs that may arise.

Commercial HVAC maintenance plans
Commercial businesses can also benefit from investing in an annual HVAC maintenance plan. Keeping your business’s HVAC equipment running efficiently offers numerous benefits, including:

  • Reducing system downtime by up to 35 per cent
  • Reducing overall energy use by up to 30 per cent
  • Preventing up to 75 per cent of all equipment breakdowns
  • Decreasing maintenance and repair costs by up to 20 per cent

If you want to sign up for a comprehensive maintenance plan, contact the team at Harmony Heating & Air Conditioning.

Winters in Alberta are long and cold. Thankfully, your heating, ventilation and air conditioning (HVAC) system can keep you comfortable and warm. However, if you want to ensure optimal performance of this essential appliance all season, it’s important to take precautions. Here’s what you should do to prepare your HVAC system for winter.

Winterize your air conditioner

Start by shutting down your air conditioner for the season. Wash and dry your unit, then protect it from ice and snow by wrapping it with a waterproof cover. Check to see if there’s a casing designed for your specific unit.

Change your air filter

Dirty filters can make your HVAC system less efficient. Replacing your filters regularly keeps dust out of your furnace so it can continue to run smoothly. Most filters should be replaced every three months, or every time the season changes. However, you may need to replace them more frequently if you smoke or have pets. Check your owner’s manual for more information on how frequently the filters for your specific unit should be replaced.

Clean your air vents

Your air vents and ducts need to be cleaned periodically to remove dust and debris that can clog the system. Cleaning your vents will also improve the air quality in your home. In addition, make sure to open and clean your vents before you turn the heat on. Blocked vents can raise your energy bill and may cause your furnace to overheat and eventually breakdown.

Test your furnace

Make sure to run your furnace a few times before it gets cold outside. Let the system run for a while and pay attention to any strange sounds or smells. If you notice anything out of the ordinary, contact a qualified HVAC technician to have it checked out.

Conduct regular maintenance

Fall is an ideal time to conduct maintenance on your heating system. Routine upkeep is the most efficient way to ensure your HVAC system continues to run smoothly. A qualified technician can catch minor issues before they become major problems. Regular maintenance can also extend the life of your furnace and consequently save you money in the long run.

Did you know your home’s heating, ventilation and air conditioning (HVAC) system can affect your sleep? Improving the quality of the air in your home can reduce nightly tossing and turning. Here are four ways your HVAC system can affect your sleep.

1. They keep temperatures stable

Research shows that people sleep better in cooler conditions. Bedroom temperatures should be between 15 and 20 degrees Celsius at night. Anything above or below this range can disrupt your sleep. Leaking ductwork, a faulty thermostat or a poorly maintained HVAC system can lead to temperature fluctuations.

Installing a smart thermostat, having your HVAC system maintained and keeping your ducts clean will all help to maintain a constant and comfortable temperature throughout your home.

2. They regulate humidity levels

Humidity levels that are too high or too low can adversely affect your sleep. If levels are too high, you may feel sweaty and sticky, and your room will attract mildew and mould. If humidity levels are too low, you could end up with a sore throat, a dry or bleeding nose and/or itchy skin.

If you’re battling uncomfortable humidity levels, consider installing a humidifier for your home.

3. They improve air quality

Poor air quality increases allergy and asthma symptoms and prevents you from getting proper rest. Dirty ducts recirculate dirt, dust, pollen and pet dander through your home, which can lead to sneezing, coughing, watery eyes and trouble breathing.

To keep the air in your home clean, it’s a good idea to have your HVAC system maintained regularly by a professional, make sure your ducts are clean and habitually change your furnace air filters. You may also want to consider installing an air purification system or electronic air cleaner (EAC) to maximize the quality of the air in your home.

4. They can make noises

An HVAC system that hasn’t been properly maintained can make noises that keep you awake at night. Old fan belts, struggling motors and loose parts can make sounds that will echo throughout your ductwork and into your bedroom.

Not only are these sounds annoying, but they’re also a worrying indication that your HVAC system needs an inspection or a repair. Alleviate the anxiety this brings by scheduling a professional technician to look at your system.

Today, washing machines have become an integral part of daily life. As such, here are six tips to help you keep your washing machine in good working order for years to come.

1. Leave the lid open
After each use, it’s a good idea to leave the lid or door of your washing machine open for at least a few hours to allow any excess moisture to evaporate. This will prevent the growth of mould and mildew and keep any musty odours at bay. This is especially important for front-loading washing machines, as these have a rubber seal that needs to be allowed to dry.

2. Keep it level
If your washing machine is off-balance, it could vibrate, rock or move across the floor during the spin cycle, which could damage your flooring or the machine itself. Fortunately, most washing machines have adjustable feet that can be moved up or down to ensure the machine stays level

3. Inspect the hoses
You should regularly inspect the hoses on your washing machine and promptly replace any that are bulging, cracking, fraying or appear to be leaking or deteriorating. It’s also a good idea to check that the fittings are tight and ensure your machine is at least four inches away from the wall to prevent the hoses from kinking.

4. Regularly clean it
It’s a good idea to periodically wash away any soap residue and scale buildup from the inside of your machine using a store-bought cleaner or a vinegar and baking soda solution. You should also wipe down the drum, door and rubber gasket at least once a month.

5. Use the right detergent
Make sure you’re using the right detergent for your specific washing machine model. For example, many high-efficiency washers require a specially formulated low-sudsing detergent. In addition, make sure you’re not using too much detergent as this can leave excess residue on your clothing and put unnecessary strain on your machine.

6. Load it correctly
You should avoid overloading your washing machine as this is hard on the equipment and could damage the motor, causing certain parts to prematurely wear out. It’s best to break up your laundry into smaller loads instead of trying to get it all done at once.

If you’re having issues with your washing machine, contact the experts at Harmony Heating & Air Conditioning.

Natural gas is one of the world’s cleanest fossil fuels. When used correctly, it’s a safe and efficient power source. However, gas leaks can occur and, if not dealt with promptly, can lead to fires or gas poisoning. Here are five signs you may have a natural gas leak in your home.

1. You smell a foul odour
Natural gas is actually odourless. However, many gas companies add a pungent, non-harmful chemical called mercaptan to the gas to make it easier for homeowners to detect if there’s a leak. Therefore, if you notice a nasty odour similar to rotten eggs, sewage or skunk, you may have a gas leak.

2. Your house plants are dying
Plants are extremely sensitive to any buildup of natural gas in the air. In fact, natural gas prevents a plant’s roots from absorbing oxygen. Therefore, if your indoor greenery unexpectedly starts to wilt and die, it could be a sign that you have a slow gas leak somewhere in your home.

3. You hear a hissing sound
If you hear a high-pitched hissing or roaring sound coming from one of your natural gas appliances, even when it’s turned off, it could indicate that you have a leak. It’s a good idea to check your pipes and appliances regularly and listen for any irregular sounds.

4. Your gas bill is higher than usual
If your gas bill has spiked unexpectedly, it could mean that you have a slow leak somewhere causing excess gas to escape from your home. Therefore, it’s important to keep an eye on your energy bills and ensure they’re consistent with how much gas you’re using.

5. You’re experiencing health issues
Breathing in too much natural gas can have serious health consequences. Therefore, if you experience persistent and unexplained headaches, dizziness, fatigue and nausea, it could be a sign there’s a gas leak in your home, especially if more than one person in your home is having the same symptoms.

If you suspect you have a gas leak in your home, immediately stop what you’re doing and leave. Get to a safe place and then call your gas company to have them turn off your gas. Afterwards, you should contact a professional gas line repair expert to inspect the problem and make any necessary repairs.

Since garages typically have less insulation than the rest of your home, you may want to invest in a garage heater to use during the cold winter months. Here are four safety tips to keep in mind when using a garage heater.

1. Don’t run the heater unsupervised
You should only use your garage heater when you’re at home. Even if you’re only planning to run a few quick errands, it’s best to turn off the unit and unplug it anytime you leave the garage. In addition, you should avoid leaving your garage heater running all night while you’re asleep. The unit could overheat, short-circuit or tip over, causing a fire to break out.

2. Install proper ventilation
Garage heaters need to be well ventilated to prevent the buildup of dangerous fumes, such as carbon monoxide. If your unit doesn’t vent directly outside, make sure there’s adequate airflow in the space. As an extra precaution, you should install a carbon monoxide detector to alert you if the level becomes unsafe.

3. Plug the heater directly into an outlet
You should never plug your garage heater into an extension cord or power strip. Since garage heaters require a considerable amount of power, they could cause the extension cord or power strip to short-circuit or overheat, potentially causing a fire. Instead, always plug your garage heater directly into a wall outlet. You should also avoid plugging other devices into the same outlet when the heater is running.

4. Remove any obstructions
Don’t store anything on or around your garage heater, especially fabrics and paper products such as cardboard, as these materials are extremely flammable. In addition, make sure you periodically clear away any dirt, dust and debris from around your unit that could easily catch fire. Generally, you should leave at least three feet of space around the heater in all directions. In addition, if you have a free-standing unit, don’t place it on top of a table or another piece of furniture, as a family member or pet could knock it onto the floor and potentially start a fire.

Lastly, whether you need a wall-mounted, free-standing or floor heating unit, Harmony Heating & Air Conditioning has what you need.

Garage Heaters in Calgary
Whether you use your garage as a workshop, storage space or a place to simply park your vehicle, investing in a garage heater has numerous benefits. Fortunately, Harmony Heating & Air Conditioning carries a variety of garage heaters to meet your specific needs. We also repair and install furnaces, hot water tanks, air handlers and more.

If you’re renovating your bathroom, here are six things to take into consideration when purchasing a new toilet.

1. Rough-in measurements
Before you purchase a new toilet, you must determine how much space you have to install it. The most important measurements are the rough-in dimensions. This is the distance between the floor drain and the wall. Standard toilets have a rough-in of 12 inches. However, 10-inch and 14-inch rough-in toilets are also available.

2. Bowl height
Standard toilets are between 14 and 15 inches tall and are suitable for shorter people and young children. However, you can also purchase comfort toilets, which are 16 to 17 inches tall and are better for tall people or individuals with limited mobility.

3. Bowl shape
Elongated toilet bowls provide more sitting room and tend to be more comfortable than round bowls. However, round bowls are more affordable and are suitable for smaller bathrooms since they take up less space.

4. Style
There are three basic styles of toilets: two-piece, one-piece and wall-mounted. Two-piece toilets are the most common type of toilet on the market. They’re affordable, easy to repair and are known for their durability. On the other hand, one-piece toilets are one seamless unit, making them stylish and easy to clean. However, they tend to be a bit pricey. Lastly, wall-mounted toilets are mounted directly to the wall and don’t have a foot or base. Since the tank is hidden inside the wall, these types of toilets can be expensive to install and repair.

5. Water efficiency
Standard toilets use about six litres per flush. However, if you want to save on your water bill, you may want to purchase a high-efficiency or dual-flush toilet. High-efficiency toilets use three to four litres per flush. In addition, dual-flush toilets bring the best of both worlds, as you have the option for either a full or partial flush.

6. Flush performance
Flush performance measures a toilet’s ability to clear waste in one single flush. Consequently, toilets with a higher flush rating offer better waste removal and clog resistance. You should look for toilets with a flush performance of at least 350 grams. However, toilets with a flush performance of 700 grams or higher will be more reliable.

You may also want to consider installing a bidet or splurging on features such as a soft-closing or heated toilet seat.

Indoor air quality affects your overall well-being. Consequently, the furnace filter you choose can have a significant impact on your health and that of your HVAC system.

What’s a MERV rating?

MERV stands for minimum efficiency reporting value. The ratings range from 1 to 16 and are used to evaluate the efficiency of an air filter based on how effective it is at catching particles of varying sizes. Consequently, the higher the MERV rating, the more effective the filter is at removing particles from the air. It’s recommended that homes and businesses use a furnace filter with a MERV rating of at least 8.

Types of furnace filters

It’s important to know the differences between each type of filter to determine which one is most suitable for your needs. Here’s an overview of four of the most widely available furnace filters:

1.  Fibreglass filters are the cheapest option. However, they need to be changed monthly and only filter out large particles such as lint and dust. Since fibreglass filters only have a MERV rating of 2 or 3, they aren’t ideal for people who suffer from asthma or allergies.

2.  Electrostatic filters use self-charging fibres to attract and lock in airborne particles like magnets. They come in disposable and reusable versions, depending on the requirements of your furnace. Most electrostatic filters offer a MERV rating between 4 and 10. Consequently, they’re great for homes with smokers or pets.

3.  Pleated filters are the most common type of furnace filter and come in a variety of sizes to fit most HVAC units. They’re affordable, efficient and long-lasting. Pleated filters effectively remove small particles from the air and usually have a MERV rating of 7 or 8 but can be as high as 13.

4.  HEPA filters, or high-efficiency particulate filters, remove up to 99% of airborne allergens and pollutants. They usually have a MERV rating between 12 and 16. However, HEPA filters are quite expensive and can restrict airflow to your HVAC system.

If you’re not sure which filter is right for your furnace, the team at Harmony Heating & Air Conditioning would be happy to help you find one that meets your needs.

During the summer, the humidity level in your home may rise. Although this phenomenon is normal, when excess moisture in your home is left unchecked, it can encourage mould and bacteria to proliferate and cause damage to your walls, furniture and wood flooring. Here’s what you should know about managing humidity in your home.

How to prevent humidity from becoming an issue

Here are five tips for keeping the humidity level in your home in check:
1.  Change or clean your air filter every 30 to 60 days. This will ensure your AC system is working efficiently and that any excess moisture in your home is eliminated.

2.  Seal leaks around your windows and doors with caulk and weatherstrip to create an airtight seal and prevent humid air from entering your home.

3.  Actively use your bathroom, kitchen and dryer exhaust fans to help remove excess humidity from the air caused by showering, cooking and drying clothes.

4.  Use portable and/or ceiling fans to increase air circulation throughout your home. The breeze will help evaporate any excess moisture in the air to keep your home cool and comfortable.

5.  Install a dehumidifier on your AC system to keep humidity levels under control. For example, a whole-home dehumidifier can be retrofit to your existing unit to help remove moisture from the air as it enters your home. If you don’t want to invest in a such a large system, purchasing a portable dehumidifier can help decrease the humidity in certain rooms.

If you’re concerned about the humidity level in your home, you may want to invest in a hygrometer or humidistat so you can monitor it more closely. In general, a relative humidity level between 30 and 50 per cent is ideal.

How to tell if the humidity in your home is too high

There are three telltale signs of high indoor humidity: condensation or fog along the edges of your windows, mould growth and a persistent, musty smell. If you notice any of these signs, it may be time to have one of the HVAC specialists in Calgary from Harmony Heating & Air Conditioning come and inspect the issue. Getting to the root of the problem is important for keeping you and your family safe as well as ensuring your AC system doesn’t become overworked.

Are you wondering whether to retrofit or replace your boiler? If so, there are several factors to take into consideration including the age, energy efficiency and condition of your existing system, as well as your budget. Here’s an overview of each option.

Boiler retrofit

A boiler retrofit involves replacing parts or upgrading equipment to increase the energy efficiency and safety of your existing system. Consequently, if your boiler is old but still in relatively good condition because it’s been well-maintained, a retrofit is likely the most cost-effective option.

Here are a few examples of upgrades that can be made to your boiler to increase its performance:

1.  Install a modulating aquastat. If you have a hot water boiler, this device automatically regulates the temperature of the water inside based on the outdoor temperature, saving you money on fuel costs.

2.  Add a time-delay relay. This device tells your boiler to circulate the residual hot water in the system for a set period of time before turning on the burner to save on energy costs.

3.  Update the ignition. Old boilers have a continuously burning pilot light that ignites the burners. You can increase your boiler’s efficiency by upgrading to an intermittent ignition device that only turns on when needed.

In many cases, these changes will pay for themselves over a short period of time.

Boiler replacement

If your boiler is old, inefficient, oversized and/or leaking, a replacement may be the most practical option. When shopping for a new boiler, keep an eye out for the Energy Star label. This certification is only given to the most efficient and well-performing boilers. Although pricey, Energy Star-rated boilers are more environmentally friendly and can save you thousands of dollars in energy and maintenance costs over the lifespan of the system.
If your boiler isn’t performing as well as it used to, the expert Calgary HVAC technicians at Harmony Heating & Air Conditioning can help. They’ll visit your home or business and inspect your system to determine if a simple retrofit or entire replacement is necessary.

Boiler retrofits and replacements in Calgary

Heating and air conditioning units contain chemicals (such as Freon) that are harmful to people, animals and the environment. When released into the atmosphere, Freon and other refrigerants can destroy the ozone layer and contribute to climate change. This is why it’s illegal to throw your old air conditioning unit in the trash. So, how do you get rid of it? Here are some ways you can safely dispose of your old HVAC unit

You can sell it

If your HVAC is still functional, it can be reused. You can either sell it or give it to someone in need. Consider donating it to a thrift store or charity. If it’s not in good working order, you may be able to repair it. A qualified HVAC technician can fix leaks in the piping, repair broken condenser fans, clean the internal systems and top up the refrigerant coolant.

You can recycle it

Many recycling centres take in old HVAC units. This is because the metals and plastics inside can be stripped and reused. Some recycling centres may charge you to remove the refrigerant, but other will pay you for the scrap value of the unit. In addition, some energy companies offer incentives for recycling your old appliances with them. You may be able to receive a rebate or discount on a new, energy-efficient HVAC unit.

You can dump it

Some municipalities require that you prepare your HVAC or air conditioning unit by having the refrigerant removed before discarding the appliance. According to Environment Canada regulations, only a certified technician can handle and remove refrigerants. You can pay an HVAC technician to prepare your air conditioner before bringing it to a landfill or hazardous waste facility. Alternatively, you can pay a junk removal specialist to pick it up for you.

You can replace it

Many HVAC companies will remove your existing unit when they install a newer model. These companies will either recycle or dispose of the old appliance safely. Certified HVAC companies can drain the refrigerant from the unit before getting rid of it at an approved reclamation centre.

A fan coil unit (FCU) is a device that contains a heat exchange coil and a fan. FCUs are often used as standalone devices for heating or cooling a space, but they can also be used as part of an existing HVAC system. They provide individual, room-level temperature control and are available in horizontal, vertical, ceiling and wall-mounted units. Here’s what you should know about these devices.

The importance of fan placement

There are two main types of FCUs: blow through and draw through. The difference lies in the placement of the fan. In the former case, the fan is fitted behind the coil and in the latter, the fan is fitted in front of the coil. Draw through units are more efficient since they pull the air through the device. However, they’re also more expensive.

The role of hot and cold water

Air temperature is adjusted when it passes over a coil that’s supplied with either hot or cold water from a central chiller or boiler. A two-pipe FCU system contains only one coil that serves as either a heating or cooling coil depending on the system. A four-pipe FCU has both heating and cooling coils and includes a distribution system that contains return lines for both hot and cold water supply.

The heating/cooling process from start to finish

First, air is sucked into the unit from the return grill. It then passes through a filter to remove dust and dirt particles. Then, the clean air then moves over the coil and is either heated or cooled through heat transfer. In the summer, as the air cools, water vapour condenses from the air, reducing its humidity. The FCU contains a drip tray with a drain connection to capture and remove the condensation. Lastly, the fan blows the temperature-adjusted air into the space.

The advantages of fan coil units

FCUs have many benefits. They’re:

  • Simple and affordable to install
  • Energy efficient
  • Simple to clean
  • Durable and easy to maintain
  • Available in many different designs

There are multiple reasons to choose FCUs over other devices. If you’re unsure which heating and cooling system is right for your home or business, the experts at Harmony Heating & Air Conditioning can help.

2. It removes odours and vapours. In addition to irritating your nose, unpleasant smells can be bad for your health. PureAir™ breaks down odours and chemical vapours, neutralizing smells and rendering them harmless.

3. It reduces ozone. Some air purifiers create ozone, a known lung irritant. However, PureAir™ doesn’t generate any ozone. In fact, its carbon filter reduces the amount of ozone generated by other sources in your home.

4. It’s energy efficient. PureAir™ provides effective air filtration without using much electricity, making it a smart solution.

In addition, a whole-home air purifier can provide peace of mind, ease allergy suffering and protect you and your family from viruses and bacteria.

Are you looking for ways to reduce your household’s expenses and carbon footprint? Here are five tips to help you make your home more energy efficient, thereby lowering the cost of your heating and cooling bills.

1. Book regular service calls
It’s recommended that you have your heating and cooling units inspected by a qualified HVAC technician at least once a year. During these visits, the technician will clean components and make any necessary repairs to ensure the system runs optimally. This will help your HVAC system use less energy, reduce the likelihood of costly breakdowns and extend its lifespan.

2. Clean the ducts annually
Similarly, you should have your home’s ventilation system (which includes the ducts, vents and registers) inspected annually by a professional. An HVAC technician will look for leaks and blockages that can significantly reduce the efficiency of your heating and cooling systems, thereby increasing the cost of running them and the risk of premature wear.

3. Replace the air filters
Over time, the air filters in your furnace and air conditioner accumulate dust and other debris that circulates through your home’s ventilation system. This can create blockages that decrease the efficiency of your HVAC system. To ensure your heating and cooling units run optimally, be sure to replace or clean their air filters every three months.

4. Seal any air leaks
If drafts are being let in around your windows and doors, your heating and cooling systems will have to work harder to regulate the temperature inside your home. Check for air leaks, and add caulking or replace old weatherstip where needed to properly seal your doors and windows. Depending on their condition, you might want to consider upgrading to more energy efficient models.

5. Invest in window coverings
Installing blinds, solar shades or thick curtains is a simple way to lower the cost of running your HVAC system. During the summer, these window coverings can be used to block out heat from the sun so that your air conditioner doesn’t have to work as hard. Conversely, in winter, you can let the sun warm your home during the day and cover the windows at night to retain the heat.

If you want to upgrade the heating system in your home, you may be wondering whether to invest in forced-air central heating or radiant in-floor heating. While both systems are sure to keep your home cosy in the winter, they each come with benefits and drawbacks. To help you make an informed decision and choose the right option for your home, here’s an overview of these two popular heating systems.

How they work
A radiant in-floor heating system uses either electric coils or tubes filled with hot water installed beneath the floor to heat your home. When the system is turned on, heat radiates upward and warms the entire space.

A forced-air system, on the other hand, heats air in a central location using a boiler, furnace or heat pump. A fan then pushes this heated air through ducts and delivers it to the various rooms in your home.

Pros and cons of radiant heating
Radiant in-floor heating provides an even temperature throughout a space, as warm air continuously rises from the entire surface of the floor. And since this process happens without the need for air movement, a radiant heating system doesn’t stir up dust, pet dander and other allergens.

Although the upfront cost of radiant in-floor heating is higher than that of a forced-air system, you’ll save money in the long run since radiant heating is more energy efficient. Plus, it can be installed beneath any type of flooring and doesn’t take up nearly as much space as a furnace or heat pump.

Pros and cons of forced-air heating
One advantage of a forced-air heating system is that the ducts can be used to both heat and cool your home. And while the system’s fan inevitably stirs up particles, you can easily maintain a healthy indoor air quality by regularly cleaning or replacing the filters.

Another plus is that forced-air heating systems are more affordable than radiant in-floor heating. They’re not as energy efficient, however, and they require more upkeep and more frequent repairs. Additionally, forced-air systems have a tendency to be noisy and provide uneven heat distribution, although newer models have shown big improvements in these areas.

If you own a pet, you’ll need to take a few additional steps to keep your HVAC system in good condition. This is because fur and dander can easily infiltrate the system, causing blockages and other problems that force your heating and cooling units to work harder. Here are a few tips to ensure your HVAC system runs optimally even with your furry friends around.

1. Replace the filter often
The filter in a furnace or air conditioner is designed to prevent dust and other particles from clogging up the appliance. Over time, however, an accumulation of fur and dander can prevent air from properly circulating through your HVAC system. This forces the fan to work harder and reduces the efficiency of the unit.

As a general rule, you should clean or replace your HVAC filters every three months. However, it’s best to check the filters for clogs about once a month if you have pets.

2. Invest in an air purifier
In addition to regularly swapping out the filters in your heating and cooling systems, you may want to consider buying an air purifier. In addition to improving the indoor air quality of your home, this device can remove a significant amount of particles from the air before they get near your HVAC system.

3. Clean the ducts regularly
Similar to the filters in your furnace or air conditioner, fur and dander can accumulate in your home’s ventilation system. Without proper upkeep, this can lead to blockages and inefficient air circulation. To help keep your ducts clean, vacuum the floor vents every few weeks. Remove the grate, and use the hose attachment to reach as far into the vent as possible.

While regular vacuuming can reduce the risk of blockages, you’ll need to have your ducts professionally cleaned every few years to keep your HVAC system running optimally. In addition to this deep clean, an HVAC technician will inspect the system and make any necessary repairs.

4. Keep pets away from the unit
In addition to the problems caused by fur buildup, your HVAC system can be severely damaged if your pet chews on wires or urinates on the unit. It’s also hazardous for your pet to get too close to a furnace or air conditioner. For these reasons, it’s best to keep your heating system behind closed doors or blocked off by a gate. Similarly, you should install a fence around an outdoor air conditioning unit to keep animals away. Just make sure the barrier is about a metre away from the vents so that air can properly circulate.

Are you in the market for a new air conditioner for your home or business? If so, opting for an energy efficient model is a worthwhile investment. In addition to reducing your carbon footprint, you’ll save considerably on your heating and cooling bills. Here are a few tips to help you find an energy efficient unit that suits your needs.

Check for Energy Star certification
In order to receive this type of certification, an appliance must meet certain standards for energy efficiency. If you find an air conditioner with this signature blue label on it, you can be sure the model will use less energy than similar, uncertified models.

Read the EnerGuide label
An increasing number of air conditioners now come with an EnerGuide label. Among other things, this label indicates how much energy an appliance uses in kilowatt hours. It also compares the unit’s energy usage to that of similar models on the market. This information can be crucial if you’re trying to choose between two air conditioners.

Select the right size AC
To maximize the energy efficiency of your air conditioner, it needs to be appropriately sized for the space. If the unit is too small, it might end up running constantly without ever sufficiently lowering the indoor temperature. Conversely, if the unit is too large for the space, it won’t run long enough to remove humidity from the air. This excess moisture can leave you feeling clammy and uncomfortable.

Opt for a programmable unit
Fortunately, most modern air conditioners come with programmable temperature settings that ensure the unit automatically shuts off when the air reaches a precise temperature. Additionally, you can program it to vary the indoor temperature during the day based on when you’ll be home so that it doesn’t run unnecessarily.

Speak with a professional
One of the best ways to accurately compare air conditioners and determine which one is the most energy efficient is to consult an HVAC technician. These professionals can also assess what size unit is needed for your home or business. Plus, once you’ve selected a unit, they can take care of the installation as well.

Did you know that the indoor air quality of your home can greatly affect your and your family’s health? For this reason, many people rely on electronic air cleaners to keep the air in their home safe. But are these types of air purifiers really worth it? Let’s take a look.

Who can benefit?
If you or another member of your household has a respiratory condition, such as asthma, or an allergy to dust, pet dander or fur, an electronic air cleaner will likely be a worthwhile investment. Since this device traps particles and prevents them from re-circulating in your home, it can help reduce the frequency and severity of symptoms triggered by exposure to air pollutants.

What upkeep is required?
If you want to equip your furnace or air conditioner with an air purifier, it’s important to be aware that certain maintenance will be required. As dust and debris accumulates in the filter, it’ll become less effective and can even lead to bacteria growth. Therefore, to fully benefit from an electronic air cleaner, you’ll need to regularly replace the filter and inspect it for other signs of wear.

Are there other solutions?
Before you invest in an electronic air cleaner, it’s a good idea to identify the source of your home’s poor air quality. For example, make sure that your allergy symptoms aren’t being triggered by mould spores caused by water damage in your basement or around leaky windows. You might also simply need to schedule more frequent HVAC service calls to keep your home’s ventilation system in peak condition.

However, if you’re unable to eliminate the source of the problem, such as if you have pets, an air purifier can be an effective way to remove excess particles from the air

How can you reduce costs?
If you want to add an air purifier to your HVAC system, the best time to do so is when you upgrade the existing heating or cooling unit. Since you’re already paying to have a new system installed or an old unit replaced, the extra work to include an electronic air cleaner will be more affordable.

Do you rely on your air conditioner to keep you cool and comfortable during the summer months?  If so, you should know that your AC needs to be properly maintained in order to continue functioning properly. However, even with proper maintenance, replacement will eventually be necessary when the machine reaches the end of its lifespan.

Here are some factors to consider when deciding whether you should repair or replace your AC:

  • How old the unit is. Generally, an air conditioner will last 10 to 15 years. If your AC is nearing the end of its lifespan, repairing it may not be worthwhile. Additionally, due to advances in technology, a new unit is likely to be more efficient and cost less to run.
  • Whether it uses R-22 Freon. This once common refrigerant is known to be a dangerous, ozone-depleting substance. As such, the Government of Canada banned the sale of all Freon-based products and Freon itself will be made illegal in the coming years. If your AC unit uses R-22 and develops a leak, you won’t be able to purchase new Freon to top your system up.
  • How often it breaks down. If your air conditioner regularly needs repairs, it may be time to replace your unit. A machine that constantly has problems is reaching the end of its usable lifespan. Additionally, frequent repairs can be costly, and an AC replacement may save you money in the long run.
  • The cost of repair. If you’re still not sure if you should fix or replace your AC unit, an HVAC specialist can give you an idea as to how much a repair will cost. This will allow to compare the price of a replacement versus the cost of a repair. A simple, inexpensive fix is usually worth it, especially if your unit is still relatively new. However, if the repair will cost as much as a replacement, it’s better to invest your dollars in a new air conditioner.

Do you need to replace your furnace? If so, the kind you select should depend on a number of factors, including the size of your home, the existing ductwork and insulation, and your budget. Here’s what you should know about furnaces before you purchase one.

Furnace types

There are three main types of furnace to choose from:

  1. Single stage. The most basic type of furnace, a single stage model only has one setting. These furnaces are designed to run at a constant speed and generally make more noise than other options.

    However, this kind of furnace isn’t suitable for Calgary winters. Though they’re inexpensive to purchase and install, single stage furnaces don’t heat efficiently enough to battle our long, cold winters.

  2. Two stage. This type of furnace has more options than a single stage furnace. A two stage model run at about 65% of its full force most of the time, which generally provides enough heat for a home during moderately cold periods. When temperatures drop lower, the second stage activates a high fan speed, spreading more heat than usual.

    This kind of furnace is more expensive than the single stage variety, but it’s better able to heat a Calgary home and requires less energy to run. Additionally, because it’s not on at full force most of the time, it tends to make less noise.

  3. Modulating. Using advanced heating technology, a modulating furnace delivers even heating throughout your home. This furnace’s power output can increase or decrease at 1% increments, allowing it to operate at peak efficiency at all times.

    A modulating furnace is the most efficient type of furnace on the market. This means that by investing in one, you’ll save money on your energy bills. It’s an excellent choice for Calgary homeowners looking to keep their home at a consistent temperature all winter long.

Fuel types

Another factor to consider when choosing a new furnace is the energy that’ll be used to run it. Electricity, natural gas, oil, coal and wood are all commonly used fuel sources for home heating. The best option for your home will depend on a number of factors, including cost and the energy source that’s currently used to heat your home.
