Now that winter is behind us, it’s a good time to take stock of what needs maintenance or replacement in your home. Calgary winters give the residents a run for their money. If you feel like your heating system might not hold up through another cold season, it’s time to consider furnace replacement for your Calgary home or business.

Homeowners rarely want to think about replacing their heating systems because the furnace replacement cost can feel overwhelming. But at Harmony Heating and Air Conditioning, we offer expert Calgary-area furnace installation at a fair price. And with financing available, it is simple and affordable to get your home or business in top shape before next winter.



Most Calgarians rely on a central furnace for their heating needs. When these units are working great, life is lovely. You can stay warm and safe all winter. But when they fail, things can get bad quickly.

Fortunately, your furnace typically gives you some warning that it needs help. Watch for these six signs that it may be time for a new furnace in your Calgary home or business.

  1. It seems excessively noisy
    If you hear buzzing, rattling, or humming from your heating system, it isn’t doing well. If you find that you have to turn up your television significantly every time the furnace comes on, there is probably a problem.
  2. There is a lot of dust build-up in your house
    Yes, it would be lovely to use this excuse every time unexpected company drops in, but truthfully, if you are seeing more than normal amounts of dust during the winter, you may have a furnace problem. It’s time to have a Calgary heating expert come check it out.
  3. Your energy bills are rising
    If you find yourself feeling like your heating costs are going up, take a look at your statements to compare winter months over the past few years. If there are significant increases, you may need a new furnace.
  4. The rooms heat unevenly
    While there may be some slight temperature variations throughout a home or commercial property, they shouldn’t be significant. If you have difficulty getting one or two areas to heat correctly, the furnace isn’t functioning well.
  5. There are cracks or areas of rust on the furnace itself
    Any time the housing for the furnace has damage, you should have it checked out by an expert. Cracks and rust indicate that the unit probably needs replacing.
  6. It’s old
    This sign is nice and straightforward. If your furnace is approaching or has already passed 15 years old, it is likely that you will need to consider a new unit sooner rather than later. Most furnaces have a lifespan of about 15-20 years, so once you get into that range, it generally is better to replace rather than repair.



For heating in Calgary, you must find a product that will work with extreme temperatures. At Harmony, we trust top manufacturers like Trane and Lennox to do an excellent job of keeping your home or business comfortable all winter long.

Because of the plummeting temperatures that Calgary experiences each year, many area residents opt for high-efficiency gas furnaces when it is time to replace their systems. If you are replacing something that is 15-20 years old, anything new will automatically be more energy efficient than what you had.

But if you are interested in a high-efficiency furnace, here are some things to know:

  • Electronic ignition
    New high-efficiency heating systems use an electronic ignition when heat is required. This takes away the need to keep a flame burning at all times.
  • Two-stage heating
    Furnaces with this capability can heat at a lower stage the majority of the time, consuming less fuel. When temperatures drop, the second stage kicks in to provide more heat. These furnaces can find a comfortable balance for your home without continually turning on and off.
  • Variable airflow
    High-efficiency furnaces can adjust airflow to maintain an even temperature while heating. These systems can detect when they need more power to disperse heat.



Harmony Heating and Air Conditioning has the experience and knowledge to provide you with excellent service for your furnace installation needs. We will take time to determine the best heating system for your home or business. Give us a call today to schedule a free estimate. When winter comes back around, you’ll be glad you did.

If you’re like many Calgarians, your garage serves several valuable purposes. Aside from protecting your vehicles from the elements, it is likely a workspace, man cave, or she shed as well. If the frigid winters make your garage unusable for many months, it may be time to consider a garage heater.

Many homes also have pipes in the garage that need protection from freezing temperatures to avoid bursting. Townhomes, in particular, tend to have this situation that requires garage heater installation in Calgary.

Our cold and snowy winters also mean that many residents enjoy outdoor winter sports such as skiing and hockey. A climate-controlled garage gives you a storage space that can protect your valuable gear.

In mild climates, residents can get by with wearing a few extra layers while working in their garage. Not here in Calgary. Not if you’d like to stay attached to your fingers, ears, and toes. Harmony Heating & Air Conditioning is the garage heater installation company you can trust to make your garage comfortable year-round.


What Are My Garage Heater Options?

There are many choices for heating your garage to make it usable for your needs. For occasional use, an electric space heater may be suitable. This option will not provide consistent protection from the winter temperatures, however. And it only heats a small portion of the garage at any given time.

Adding extra insulation and installing weather stripping around doors and windows will provide some help in keeping your outdoor workspace warmer. It is unlikely, however, to give you enough protection to make the space comfortable enough for consistent use.

Combustion space heaters that run on propane or kerosene can provide heat quickly in a garage, but they also require you to open the door to allow for ventilation. These options will not produce consistent heating to protect pipes and vehicles. They are best suited for a short-term solution until your permanent garage heater is in place.

Through our years of serving the Calgary community during the harsh winters, the Harmony Heating & Air Conditioning team has become experts at garage heater repair, replacement, and installation. We have found that a gas garage heater tends to be the most consistent and reliable heat source for your workspace. Since it vents outside the home, it is also the safest choice.

Harmony Heating & Air Conditioning offers several top-tier choices for all of your heating needs. We work with the best manufacturers to ensure you get the right product for your space. Our expert technicians will come out to see your area and talk with you about your needs before offering a no-obligation quote for garage heater replacement or new installation.

Here at Harmony, we know how to keep you and your family warm and cozy during the cold Calgary winters.

In previous posts, we discussed a number of considerations regarding your furnace.

  • How to maintain your furnace
  • Troubleshooting your furnace
  • When to replace your furnace

Let’s not forget about that beautiful gas fireplace! A well-maintained gas fireplace serves a purpose in your home; to keep you warm. That said, there are few things more inviting than the ambiance of a fire in the midst of a snowy Calgary winter.

So, let’s take a look at your gas fireplace and make sure it’s ready for the winter season.

Gas fireplaces require less maintenance than their wood-burning alternative. However, it is recommended that they be inspected and serviced once-a-year by a certified professional.

If you’d like to take on this responsibility on your own, here is a checklist for making sure your fireplace is in safe working order.


1. Confirm the Make and Model.

The easiest place to find this is to refer to your owner’s manual. If you’ve already discarded the manual months ago, not to worry, you can find this information online.

First, you’ll need to locate your model and serial number. This can be found on the rating plate in the control compartment area. This is typically under the smoke shield or on the firebox side column.

Since every fireplace is different, it is important to follow the manufacturer’s servicing and cleaning schedule and procedures for your particular model.

If you have any questions or concerns, contact Harmony, we’ve seen them all.


2. Check the Outdoor Vent.

You’ll want to make sure your fireplace vent is free and clear of any debris and obstructions.

Never start up your fireplace without making sure it will vent properly.


3. Clean the Interior of the Unit.

Remove the glass panel to clean and vacuum your unit before the first ignition of the season.

Don’t forget to wipe down the ceramic log. All of the accumulated residue from the off-season is the culprit behind that pesky unwanted odor.


4. Check the Pilot Light.

If there is a knob, click it to the “on” position.

You’re looking for a small blue flame inside the unit, this means it’s working.


5. Inspect the Glass Panel.

Be sure there are no cracks or chips in the glass. Defects in this area could allow carbon monoxide to escape into your home.

You’ll also want to ensure the doors are perfectly in place in order to maintain an airtight seal.

If you still have concerns, or one of these steps has proved challenging, we’re here to help.

A certified Harmony professional can inspect all the various components of your system and update you on how they’re performing.

Common issues uncovered during an annual inspection include minor leaks and faulty or weathering parts.

Keep your family safe and comfortable by booking a thorough inspection with a certified Harmony professional today.

Some parts of the world spend their winters enjoying balmy temperatures above 0°. Calgary does not. So when you need heating services, Harmony Heating & Air Conditioning is here to help. Whether you need routine maintenance, emergency repairs, or installation of a new unit, our expert technicians have you covered. We will come to your home or business to offer a no-obligation estimate on the work needed to keep you warm during the cold Calgary winters.

Common Furnace Problems

Troubles with your furnace may not always be apparent right away. Some issues develop slowly, and some happen suddenly. Here are three common problems.

  • Airflow You have poor airflow. If it seems that your furnace is struggling to push heat through the vents, there is probably something obstructing the airflow.
  • Pilot Light The ignition or pilot light isn’t working. Without a starter, your furnace won’t turn on. If the electric ignition or pilot light aren’t functioning correctly, you are going to be facing a chilly home.
  • Thermostat The thermostat is not functioning correctly. If the furnace’s “brain” isn’t working properly, it may not tell the heater when to turn on or off. And it may not regulate the temperature either. If your furnace doesn’t shut off, you may have a thermostat problem.


Furnace Maintenance

In a climate like Calgary’s, your heating system is one of the most important parts of your house. A consistent schedule of maintenance and servicing by the staff at Harmony will keep your furnace running smoothly. Our team will check the following for any problems that need attention:

  • Blowers
  • Air filter
  • Thermostat
  • Flame sensor
  • Drive belt

If our technicians spot any concerns, they will talk with you about a plan for heating repair. We want to help you catch any issues early on before they lead to safety problems or furnace malfunctions.

So what is a pilot light anyway?

A pilot light is a small flame, typically a small burner that uses natural gas kept continuously burning as the ignition source to heat your furnace or hot water heater.

The pilot light should be located at the bottom of your equipment and be blue in colour.  The blue flame warms your furnace or hot water heater and provides your home with the heat you need to stay warm and comfortable living through cold weather in Calgary.

The pilot light flame is the main indicator as to whether your furnace or hot water heater is working properly. If you see the flame, and it’s blue, it’s working!

If the pilot light ever goes out, and is not visible or turns to a yellow flame, this is a sign of a larger problem and we recommend you call us right away! We’re top-rated by Calgarians for our exceptional service and have an emergency hotline to serve Calgary 24-hours a day, 7-days a week, 365-days a year!

Prior to examining your furnace or hot water heater, you may discover your pilot light is by waking up to a freezing cold bedroom, or hopping in a freezing cold shower. Yikes! While efficient to wake you up in the morning, cold showers are not how we like to start our days, and our job is to keep your hot water warm when you need it most.

So you’re freezing cold and you realize your pilot light is out. Now what?

Trying to relight your pilot light can be dangerous! Whenever you’re dealing with gas, it’s best to call an expert to handle your heating situation with caution and care. We will have one of our local technicians out promptly to inspect your furnace or hot water heater and solve all of your pilot light issues.

In these harsh Calgary winters, it is too important to know whether or not your furnace and hot water tank are working correctly and what to do to avoid and fix problems. No heat or warm water in -30 is no joke, not only for your comfort but for other systems in your home too, like plumbing!

A furnace or hot water tank in need of repair can also lead to frozen pipes, plumbing work, and increased bills! So keep an eye on your pilot light, and the heating equipment in your home to stay safe and comfortable through all weather conditions.
