Why Is My Furnace Not Heating Properly?

Monday, April 9th, 2018 at 11:00 am

Gas-FurnaceIt can be especially frustrating having a climate control system fail on you just when you need it the most. We may be getting closer to the warm summer months, but we still have some cooler days and nights to deal with until then. If your furnace isn’t heating as well as it should be, you should take a look below at some of the possible reasons why.

The Air Filter is Clogged

One of the easiest issues to prevent and fix, a clogged air filter can prevent your furnace from circulating enough air while it’s on. The air filter in the furnace needs to be changed roughly every three months in order to prevent it from becoming clogged. If it does become clogged, it will block the majority of the air in the ducts from flowing into the furnace. This will reduce the output of the system significantly. Changing the filter yourself, or having a professional do it for you, will prevent this from becoming an issue in the future.

The System is Short Cycling

If the furnace is not providing enough output because it is turning on and off every couple of minutes, that means it is short cycling. Short cycling is often the result of an electrical issue, although it can also occur due to things like clogged air filters trapping heat in the furnace. Short cycling is bad news because it prevents the furnace from circulating enough heat, but it also increases the rate at which the system wears out. The longer the furnace is allowed to short cycle, the more prone to developing other issues it will become and the shorter its lifespan will be. Make sure that you call for repairs immediately if you notice your system doing this.

The Air Handler is Broken

If your furnace isn’t blowing any air at all, even though it’s on, then you might have an issue with the air handler. The air handler is the part of the system that is responsible for blowing air throughout the home while the furnace is operating. If the air handler burns out or otherwise malfunctions, the furnace will have no way to get rid of the heat it produces. You’ll need professional repairs to resolve this issue.

The Burner Assembly Is Clogged

Have you ever tried to light a gas stove, but the range just wouldn’t ignite? The same thing can happen to a furnace burner assembly. The jets in the assembly can become clogged with carbon buildup over time, making it difficult for them to ignite when they’re supposed to. If the assembly becomes completely clogged, the furnace will be unable to start burning gas to produce heat. Having a technician clean your assembly for you should resolve this particular problem. Just make sure you have it done as soon as you can.
