Should You Run Your Furnace Fan All The Time

If you plan on taking advantage of the benefits of a constantly running fan you may consider purchasing a new ECM blower motor for your furnace.

Should you run your furnace fan all the time. I have an HRV so by allowing the furnace to run 5 min an hour it moves all the dry air through the house that the HRV pulls in. Much of a furnace fans wear and tear comes from the starts and stops of the motor. If you run your fan after the coil warms up that moisture will go right back into your homes air and lower your indoor air quality.

Less startstop stress on the fan. Leaving the fan on 247 ensures cleaner air as the air is pulled through the filtration or UV light system. If your fan is running constantly the heat exchanger never gets a chance to cool down either which can cause serious issues.

If youre a cold-natured person you definitely do not want to keep your furnace fan on all the time during the winter. Moreover if you have a highly-efficient filter and UV light youre also constantly filtering and cleaning the indoor air resulting in less dust on your furniture and other personal belongings and more importantly fresher and healthier indoor air for your family and guests to breathe. Thats because the fan is not working all the time.

Keeps the ambient air at a more even temperature. Running the fan constantly also increases your systems maintenance needs. If your unit has too much capacity for your home water will condense on the cold coil.

When the furnace fan is set to on air is being cycled through your HVACs filtration system continuously. Keeping the fan running also leads to even air distribution through your home. Although replacing the filter isnt exactly a demanding task youll still need to replace it more often than you normally would.

If you decide to leave your furnace fan on for 24 hours a day 365 days a year you wont damage the fan. Alternatively I could have the HRV. This means better air qualityprovided you change your filter every few months.
