We still have a ways to go before winter is over, and that means that you’re probably still relying on your furnace to keep you warm on a daily basis. So, it’s more than a little inconvenient if your furnace isn’t actually heating as well as it should be. There are a couple of different reasons why this might be happening, most of which are going to require professional repairs. Let’s take a look at some of those reasons now.
Yeah, we know, it sounds obvious. Still, you’d be surprised how many heating “problems” could be traced back to a simple thermostat setting. Before calling for repairs, check your thermostat and make sure that everything is set properly. You should also see if everything is displaying correctly. If your thermostat seems to be showing incorrect information, or is otherwise acting strangely, a thermostat malfunction might be the source of your problem.
Clogged Air Filter
Every furnace contains an air filter, designed to protect the system from dust and other contaminants that might damage it. If the air filter isn’t cleaned or replaced often enough, though, it will become so clogged that it will prevent enough air from moving through the furnace. This can prevent the furnace from circulating enough heat through the home, and can cause a couple other serious issues that will damage the system. If you don’t know how to change the air filter in your furnace, call a professional.
If you’re using a gas furnace, as many people do, it’s also possible that the system failed to ignite for whatever reason. Your pilot light might be malfunctioning, or the burner assembly might be too clogged to ignite. Either way, until the ignition issue is fixed, your system won’t be able to generate heat.
