How Long Does a Furnace Run Per Day?

During the winter season there may be days where you adjust the temperature on your thermostat a bit, but for most homeowners, completely turning your furnace off during the winter is something that just isn’t going to happen. Though you may not be manually turning your furnace off during the day it should be noted that your furnace will cycle through periods of activity and downtime throughout the day. If you are listening closely, you will likely hear when your furnace starts up and turns off during the day.

How Long Should Your Furnace Run Per Day?

Did you know that your furnace isn’t actually producing heat 24/7? Though you may have your furnace set to a desired temperature, it doesn’t actually have to run constantly for that temperature to be maintained. Rather than running constantly, your furnace operates in cycles allowing it to heat your home without constantly being “on.” Generally speaking, your furnace will only be actively producing heat for up to 9 hours a day over multiple cycles. If you are not noticing that your furnace is shutting off regularly or are noticing very short or very long cycles it may be an indication that there is something going wrong with your furnace, or it may not be set to operate efficiently on your thermostat.

Our blog post, How Can I Know That My Furnace Is Efficient offers insight into what an efficient furnace operates like and how you can spot if your furnace may be running less-than optimally.

How Long Are Furnace Cycles?

When you want to know how long should a furnace run before shutting off, you’re going to want to learn about your furnace’s cycles. Most furnace cycles last between 10-15 minutes and in many cases, a furnace will cycle 2-3x/per hour to maintain the desired temperature within a home. So, how long should a furnace run in an hour? In most cases, a furnace will run anywhere between 20-45 minutes in an hour.

How Long Should a Furnace Run in Cold Weather?

When the weather outside is very cold, your home will lose its heat faster. This means that your furnace will likely need to complete more cycles in an hour than on days that are less cold. It would be normal for your furnace to run through three cycles an hour on the coldest days of the year. If you think your furnace is running too frequently in cold weather or are noticing it is not holding your desired temperature, check your thermostat. Switching it to auto may be more appropriate for milder winter days while setting it to “on” can ensure the fan stays running, helping to circulate warm air throughout the home more efficiently and improving the quality of air in your home.

How Can I Keep My Furnace Running Efficiently?
