The furnace is on and it’s working but it’s not producing enough heat to keep the house warm. If this is your scenario, read on!
The first and easiest thing to check is your air filter. If you have a very dirty air filter in your furnace, this could be the culprit. If you haven’t replaced the air filter in the past few months, replace it and see if the heater works more efficiently.
The other possible culprit is your gas burners. The gas burners may be dirty or need need a slight adjustment. Unfortunately, this job can be a bit tricky and we recommend calling your local heating repair contractor.
