Ever go to your air register and feel the air coming out, but it’s not warm? You may wonder if your furnace is malfunctioning, and a repair is required, but this may not be the case. A furnace fan running for extended hours doesn’t necessarily indicate any damage. A little troubleshooting may find the reason behind the constant running and have a simple fix without calling a service technician.
Why is the Furnace Fan Always Running?
The most common reason behind this issue is the settings that you’ve enabled on your thermostat. “Auto” and “On” are the only two modes. The “auto” option means the fan turns on and off automatically as the heat comes on and off. The “On” option switches on the fan, which will run whether the heat is on or not. For most people, turning to the “auto” mode will solve the problem of the fan running continuously.
However, sometimes this issue does occur due to some error in the speed modes and other technical problems. For such mechanical breakdowns, you need to call a professional service provider.
Pros of Keeping the Fan Running
There is no problem with keeping the fan on all the time because these fans were designed to run continuously for long periods. There are some benefits to running a fan all the time. Running the fans ensure proper air circulation within the home, and this is especially desirable in bigger apartments and houses. Further, continuous air circulation improves the air quality in the home, especially in cities where the outdoor air quality can be poor. Good air quality is beneficial for people suffering from allergies or asthma.
Drawbacks of Keeping the Fan Running
The primary issue of a constant running fan is higher electricity bills due to increased energy consumption. Also, if air ducts are exhausting to the outside, warm air may be pushed out by the fan triggering the furnace to come on more often.
