We’re finally starting to get some cold weather here in Southern California, which means you’re probably relying on your furnace to keep warm. Yes, now would be a terribly inconvenient time to have your furnace start experiencing trouble with its heating ability. For a lot of people, though, that’s exactly what happens. Fall and winter put more strain on your heating system than at other times of the year, which means that it’s more likely to develop issues. If your furnace is having trouble providing enough heat for your home, have a look at some of the possible reasons why below.
Burner Assembly Clogs
In a gas furnace, the burner assembly is the collection of jets that actually burns fuel to generate heat for the system. Carbon particles are created as a byproduct of combusting natural gas. These particles build up on the burner assembly jets over time, and eventually can clog them. The more jets become clogged, the more heat output the system loses. The good news is that this can be easily remedied with professional cleaning. You’re going to want to have it dealt with soon, though, because if all the jets become clogged the system will be totally unable to provide heat at all.
Air Handler Malfunctions
The air handler is a motor with a fan attached to it, which your furnace uses to circulate heat around the house during operation. Without the air handler, all the heat the furnace creates would just sit in the system and not benefit anyone. If you hear a grinding sound while the furnace is on, it might mean that you need to have your air handler looked at by a professional. That might mean that the bearings in the air handler need to be replaced, before the burner overheats and burns out. If your furnace isn’t circulating any air at all while it’s on, that could also indicate a problem with the air handler motor.
Clogged Air Filter
If you’re lucky, the reason that your furnace is not heating could be as simple as a clogged air filter. The air filter in your heater should be replaced every three months or so, in order to remain clear and functioning properly. Most homeowners don’t even know that they have an air filter in their furnace, though, so this often isn’t done. A clogged air filter will prevent the furnace from receiving air from the ducts, which means that it won’t be able to properly heat the home. Fortunately, the only thing you need to do to resolve this is either replace the clogged air filter yourself or have a professional do it. That should restore proper heating function to the system, if that was indeed the problem in the first place.
