Why Your Furnace Isn’t Heating Well

Furnace-technicianThere are few things more frustrating than turning on your furnace in the middle of a cold day, only to have it fail to heat properly. If your furnace isn’t providing enough heat for your needs, there might be a number of different reasons why. You should call a professional technician to examine your furnace if you want to know for certain why it isn’t working properly. While you’re waiting for your technician to arrive, though, have a look at some of these possible reasons why your furnace isn’t heating the way it should.

The Air Filter is Clogged

If the air filter in the furnace isn’t cleaned out every three months or so, it has the potential to become clogged with the dust and other debris that commonly inhabits the home’s ductwork. Most homeowners aren’t even aware that their furnaces have air filters, so if you’re one of them you might have a clogged air filter. A clogged air filter will prevent the majority of the air in the ducts from making it into the furnace, cutting into its output significantly. Check your air filter to see if this is the cause of your issue, and replace it if necessary.

The Burner Assembly is Clogged

The burner assembly is the part of a gas furnace responsible for igniting the natural gas to generate heat. Over time, carbon particles build up on the jets in the burner assembly and cause them to become clogged. The more clogged a burner assembly is, the more difficulty it will have providing enough heat. If the burner assembly becomes completely clogged, the furnace will be unable to provide any heat at all. Fortunately, this is fairly easily fixed. You just need to make sure that you have a professional technician clean out your burner assembly for you.

The System is Short Cycling

If the reason the furnace isn’t heating properly is because it’s turning off before it can complete a full heating cycle, that’s called short cycling. Short cycling is often caused by an electrical issue, or by heat becoming trapped in the furnace due to a clogged air filter or malfunctioning air handler. At first, the only noticeable effect it will have is on the system’s heating output. As the short cycling continues, though, it will dramatically increase the rate at which the furnace wears out.

The longer the furnace is allowed to short cycle, the more prone to breaking down the system will become. Prolonged short cycling will even shorten the life of the furnace by a number of years if it is allowed to continue for long enough. Make sure that you call for repairs right away if you notice your furnace short cycling.
