If it seems like your home’s furnace is on more than it’s off, and you are beginning to wonder if there’s a problem, you’re in the right place. Your furnace shouldn’t constantly be running. This is a clear sign of an issue with the system, and there are several typical causes for this. To explore this issue, we at Hilliard-Dublin Heating & Air composed the following.
Potential Reasons For A Furnace That Won’t Shut Off
Blower Problems
How does the air from your vents feel? Is it warm or cool? When your furnace is running, but you are solely getting cool air, you could have a blower problem. One possibility is that an electrical problem, like corroded wires, is causing the blower to run continuously. If this is the case, we strongly advise you don’t try to work on the furnace yourself. Stay safe and give a trusted HVAC pro a call to conduct any repairs.
Air Filters Are Clogged
When the air arising out of your vents is warm, but the flow of the air isn’t strong, there’s a good chance your filters have become clogged up with dust and dirt. Blocked up filters prevent needed air from getting into your furnace, which makes your furnace have to work harder to reach the desired inside temperature. Try to replace your air filters with ones that are new and clean and see if that solves the problem. If not give us a call.
Thermostat Problems
Check your thermostat and make sure that it’s set to the temperature you desire and that it’s set to the “auto” setting instead of the “on” setting. The “on” setting makes your furnace run continuously. “Auto” makes your system run until it reaches the desired temperature. It shuts off on its own once that desired temperature has been reached unless the temperature falls below that setting, which will trigger it on again. Now, if your thermostat settings appear correct, and the furnace keeps running constantly, you might have a defective thermostat. Call an HVAC specialist to examine, calibrate, or perhaps even replace it.
Pilot Light Problems
Some older furnace models have a pilot light that’s intended to remain lit completely through the winter. However, if this manages to go out, it could cause your furnace to run continually running and blow only cool air. If this is the case, you may relight your pilot according to the instructions for your unit. However, most furnaces these days come with electric start pilots that automatically light once it calls for heat. It’s conceivable that somewhere inside that mechanism, there is a malfunction causing the pilot not to light. An HVAC pro can fix this.
