If your furnace isn't warming your home as it should, there may be a simple solution that doesn't require the assistance of an HVAC pro. The following tips can help you troubleshoot the problem.
Make sure that the thermostat is set correctly. It should be in "heat" mode, and the temperature called for must be above the room temperature that's displayed. Also check that the fan is in the "auto" position so that it only operates when the furnace is running.
Check the thermostat itself. If you have a digital thermostat, replacing the batteries may solve the problem. With an older, manual unit, remove the cover and clean the contacts.
Examine the furnace filter. If the filter's clogged with dirt, it can adversely affect the flow of warm air that arrives at your registers. To maximize your furnace's efficiency during the heating season, clean or replace the filter once a month.
Check the gas shutoff position. The shutoff is located along the gas line that runs from your furnace, and the handle must be set parallel to the pipe so that fuel reaches the burner.
Look inside your breaker box. Is the furnace not warming your home at all? A tripped breaker could be the reason why. If everything looks fine inside your main electrical service box, check for a blown fuse and/or flipped breaker in the furnace's blower compartment.
Check your pilot light. If the pilot light has gone out on your older furnace, look for instructions on how to relight it right on the unit, next to the pilot light opening. Alternately, they should be in your owner's manual.
If the above tips don't help, or if you have a newer heating system with an intermittent or hot surface ignition, give your HVAC professional a call. He or she may diagnose another common problem such as inadequate airflow to the combustion chamber, or a dirty gas burner.
