4 Furnace Troubleshooting Tips to Keep Your System in Top Shape

Help your furnace stay in shape this season with these helpful tips

Nothing hurts your home comfort during the winter like problems with your furnace. Fortunately, you can always rely on the experts at Roth Heating Company—we put together four furnace troubleshooting tips that can help you fix some common heating problems yourself, rather than calling a pro for professional furnace repair.

Not Enough Heat? Replace Your Air Filter

Help your furnace stay in shape this season with these helpful tipsDirty furnace filters may be blocking heat from flowing through your vents. Simply slide out the clogged filter and replace it with a clean one. Remember to put in the new filter according to your furnace owner’s manual or the directions marked on the filter frame—it’s important to make sure it complements airflow. Be sure to change your air filter regularly to prevent problems like this in the future. Swap standard filters once every one to three months and high-efficiency filters once every six to 12 months.

No Heat at All? Clean the Furnace Area and Unblock Vents

Storing too many items near your furnace can prevent it from functioning properly and even be dangerous. Make sure the area surrounding your furnace is clean—regularly vacuum dust to prevent your furnace filter from clogging sooner than usual.

Blocked vents can also cause a lack of heat. Inspect your home’s cold air returns and heat vents to ensure that no curtains, furniture, or other objects obstruct the openings.

Furnace Won’t Turn On? Check the Circuit Breaker

Find your home’s circuit breaker and check if the furnace switch is in either the “Off” position or between “Off” and “On.” If so, flip the switch back into the “On” position. If that doesn’t work, the problem may reside in the wiring or the circuit breaker itself—in which case you’ll need to call in a professional for help.

Furnace Not Running? Check the Thermostat

As simple as it sounds, sometimes your thermostat is to blame for a dysfunctional furnace. Make sure it’s on and set to “Heat.” Set it a few degrees above the current temperature to see if the thermostat is the culprit. For programmable thermostats, be sure to check that the date and time are set correctly, too—it’s possible that it’s on a set schedule. If none of that works, replace the batteries and try again.
