Summer Comfort: The Surprising Benefits of Keeping Your Furnace Fan On

Running your furnace fan during the summer can offer several benefits. Here are five reasons why you might consider doing so:

Running your furnace fan in summer has a lot of benefits.

Improved Air Circulation: Running the furnace fan during the summer helps circulate the air throughout your home, promoting better airflow and reducing stagnant air pockets. This can help maintain a consistent temperature and prevent hot or cold spots in different rooms. By keeping the air moving, you can enhance overall comfort in your living space.

Enhanced Air Filtration: Furnace fans typically have built-in air filters that capture dust, allergens, and other particles as the air passes through the system. Running the fan continuously helps improve air filtration, as it continuously draws air through the filters, trapping and removing contaminants. This can lead to better indoor air quality and a reduction in respiratory irritants.

Balanced Humidity Levels: The constant circulation of air achieved by keeping the furnace fan on can help distribute moisture evenly throughout your home. This can prevent excess humidity from building up in certain areas and minimize the risk of mold and mildew growth. Balanced humidity levels contribute to a more comfortable indoor environment, reducing the chances of dryness or excessive moisture.

Energy Efficiency: Modern furnace fans are designed to be energy efficient. Running the fan alone consumes significantly less energy compared to operating the entire cooling system. By using the fan independently during mild summer weather, you can maintain a comfortable environment while minimizing the energy consumption associated with running the air conditioner.

Noise Reduction: Furnace fans are generally quieter than air conditioning units. If you find the noise of your air conditioner bothersome during nighttime or when trying to concentrate, switching to the furnace fan can provide a quieter alternative.

FAQs

Should I run my furnace fan in summer?

Yes, for most Edmonton homes. Setting the thermostat fan to “On” keeps air circulating and filtered and uses far less energy than the air conditioner. Switch to “Auto” if the air ever starts to feel humid.

Does running the furnace fan cool the house?

No. The fan moves and filters air but does not lower the temperature. It makes rooms feel more even and comfortable, and it pairs well with your air conditioner on hot days.

Does leaving the furnace fan on use a lot of electricity?

Modern furnace fans are efficient and draw a fraction of the power the full cooling system uses. Running the fan alone on mild days is an easy way to stay comfortable for less.

“Auto” or “On” in summer?

Use “On” for constant circulation and filtration. Use “Auto” if you would rather the fan ran only during heating and cooling cycles, or if indoor humidity climbs.
