Why Does My Furnace Keep Running

Jan 26, 2020

If it sounds like your home’s heating system is running more than it’s not, and you are starting to suspect that there’s a problem, you are reading the right article. Your home’s furnace should not be continually running non-stop. This is a distinct indication of a problem with the system, and usually, you can trace back these symptoms to a few common causes. To examine this issue, we at Beavercreek Heating & Cooling prepared the following.

 

Likely Reasons a Furnace Would Run Constantly

Blower Issues

Check the air that is coming out of your vents. Does it feel cool or warm? If your furnace is constantly running, but strictly cool air is coming out, you might have a problem with your blower motor. Sometimes an electrical problem, take corroded wires, for instance, can tell your blower to run continuously. If you discover this is what’s causing your problem, we firmly recommend that you do not attempt to work on the furnace yourself. This is not a DIY job. Put safety and efficiency first by giving a trusted HVAC pro a call to handle any servicing.

Clogged Up Air Filters

If the air flowing from your vents is warm, but the flow of the air is not adequate, there’s a likelihood that your filters could have grown dirty and could have gotten clogged up with dust and particles. Obstructed air filters block the air that your furnace needs from getting there, which makes your whole system have to labor needlessly to arrive at the same desired temperature in your home. This problem is easy to solve, however. All you have to do is replace your air filters with new ones and see if the problem goes away. If it doesn’t, give us a call.

Thermostat Difficulties

Examine your thermostat and be certain that it has been fixed to the temperature you want and that it has been set on the “auto” setting rather than the “on” setting. The “on” setting tells your furnace to run continuously. “Auto” tells your system to run until it arrives at the desired temperature. It then turns off automatically when it reaches that exact temperature, except when the temperature drops below that level again, which will tell it to come on again. However, if your thermostat’s settings seem correct, and the furnace still keeps running non-stop, there’s a chance you could have a defective thermostat. If you suspect this is the case, reach out to an HVAC specialist to examine, calibrate, or perhaps even replace it.

Pilot Light Difficulties 

A lot of more antiquated furnace models have a pilot light that’s designed to remain lit entirely throughout the winter. However, if this happens to go out, it could cause your furnace to run non-stop, and blow only cool air constantly. If you discover this is the problem, you could relight your pilot in accordance with the manufacturer’s instructions for your unit. However, most furnaces these days are equipped with electric start pilots that automatically light when it calls for heat. It’s possible that somewhere inside that device, there is a malfunction that won’t let the pilot light stay lit. If this is the issue, HVAC pro can repair this.
