The decision to run your furnace fan continuously is a personal one that is influenced by several factors, including comfort, energy efficiency, and air quality. This blog explores the implications of running your furnace fan on "On" versus "Auto" in the Calgary dry cold climate of a Calgary winter
Comfort
When your furnace fan is set to "On," it operates without rest, and air circulates throughout your home regardless of whether the furnace is actively heating. This setting can enhance comfort by ensuring that warm air is evenly circulated throughout your home. However, running the furnace fan all the time also means increased energy consumption, which can lead to higher utility bills over time.
On the other hand, the "Auto" setting allows the furnace fan to operate only when there’s a demand for heat. This setting is generally more energy-efficient because the fan runs only during heating cycles. While it may not provide the same level of comfort as the "On" setting, it helps maintain a pleasant temperature without excessive energy use. Additionally, using the "Auto" setting can prolong the lifespan of your furnace fan by reducing wear caused from continuous operation.
Energy Efficiency
One of the key benefits of running your furnace fan all the time is enhanced air filtration. This allows air to pass through your furnace's filters more frequently, which can significantly improve indoor air quality. In Calgary's dry climate, where dust and allergens can accumulate, filtration can be very beneficial individuals with allergies or respiratory issues.
However, there are drawbacks to consider when running your furnace fan all the time. The increased energy consumption can lead to higher costs, and older furnaces may struggle with continuous operation due to motor wear. Furthermore, if the furnace fan runs without heat being produced, it can circulate cold air throughout your home, which is counterproductive in winter though helpful in summer.
Air Quality
Ultimately, whether you choose to run your furnace fan continuously or use the "Auto" setting depends on your personal comfort preferences and priorities. If consistent temperature and improved air quality are paramount for you and your family during Calgary's cold months, running your furnace fan all the time might be worth considering. Conversely, if energy savings and reduced wear on your system are more important, opting for the "Auto" setting could be a better choice.
Furnace Repair
Regular furnace maintenance is an important step towards efficient furnace operation. Scheduling routine inspections can help identify potential issues before they become costly furnace repairs. Whether you need a new furnace installation or maintenance for an existing furnace, your favourite HVAC professionals can help.
