Furnace problems are more often than not the result of a lack of regular maintenance and could easily be fixed by checking thermostat settings or changing the air filter. However, there are some things that are a larger concern and should definitely be handled by the professionals. So how can you know the difference? Here are a few common problems people notice about their furnaces and the potential causes.


Broken parts


Odd noises such as squeaking, rumbling or rattling aren’t normal. Such noises could be a sign of a broken part, for instance worn out ball bearings or a frayed or slipped blower belt. Another indicator of broken parts, particularly heat exchangers, is if your carbon monoxide detector goes off. A carbon monoxide detector going off means that there could be a leak, and that’s an emergency. Carbon monoxide poisoning can be fatal.

Note that any mechanical failure could lead to a leak, so don’t wait for your detector to go off. If you suspect broken parts, it’s imperative to contact a professional for urgent furnace repair or replacement.

Not heating enough or not heating at all


If your furnace isn’t providing enough heat, there are a few possible culprits. The first thing to check is the thermostat settings. Are they higher than the room temperature? Are the thermostat batteries functioning? Once you’ve eliminated these possibilities, you can consider other culprits.

Check that your circuit breaker is on and that your furnace is the right size for the space you’re heating. Finally, verify that the pilot light is lit. If the problem is caused by a malfunctioning pilot light, it may be best to contact a professional.

Insufficient airflow


If your furnace is working but doesn’t seem to be heating the whole house, this could be caused by airflow problems. The first thing to do is replace the air filter, which can get clogged and cause reduced airflow. Then, check that all your air vents are opened and look for leaks in your air ducts. If you can’t find them or can’t access all the areas you need to check, the best course of action is to contact a professional. Otherwise, you risk injuring yourself or damaging your furnace.
