Is your furnace on but not producing enough heat to keep the house warm?

There are two possible  causes, the most likely cause is that you have a very dirty air filter in your furnace. If you haven’t replaced the air filter in the past 2-3 months, replace it and see if the heater produces more heat efficiently.

The other possible cause is your gas burners are dirty or need need a slight adjustment. We recommend you call your local heating repair contractor to trouble shoot and repair this issue.
