It’s always nice to have a warm and cozy home during the winter time in St. Simons Island, GA. If you notice your furnace is constantly running, though, this could be an indication of an underlying problem. The heating unit will have to run more the colder it is outside, but it shouldn’t stay on around the clock. Sometimes a constantly running furnace only requires a simple fix, while other times an actual repair or replacement may be needed.

Check the Thermostat

One of the most common reasons a furnace will stay on constantly is because someone has adjusted the thermostat to an extremely high temperature. The colder it is outside, the harder the system has to work to keep the home at such a high temperature. If the thermostat is set to a temperature above 78 degrees, you may want to turn it down and see if that fixes the problem. If not, you’ll need to contact a professional HVAC specialist to perform a furnace tune-up.

Check the Filter

Another reason the furnace might constantly run is that the filter is dirty. When it’s dirty, the unit has to work much harder to deliver heat throughout the home. As a result, the furnace keeps running in an attempt to keep your home at the temperature on the thermostat.

You should change the filter once every 30 to 45 days. If you have indoor pets, changing it every 20 to 30 days is highly recommended. Pet dander clogs the filter and makes it difficult for the heating system to heat your home efficiently.

Check the Fan Limit Switch

If the fan limit switch is pressed in, this means the fan on the furnace will run all the time. Make sure this button is switched on. This way, the fan only runs when the unit is providing heat to a home during a heating cycle.
