3 Common Furnace Problems And How To Fix Them

You depend on the furnace to keep you warm during the cool, winter days. When the furnace starts acting weird or making a weird sound, it can be a little frustrating and disheartening to say the least. You are stuck trying to figure out what's going on amidst a number of other things. To help you determine what might be the problem with your heating system, here are a couple common complaints and what you can do to fix them.

The furnace is extremely noisy.

Hearing a bunch of rumbles, squeaks and rattles coming from your furnace can be a little scary at first, especially if it happens in the middle of the night. Squeaks often signal a problem with the motor going bad, while rattling and rumbling often signal the blower wheel is out of balance due to being dirty or needing to be replaced.

Air leaks can also causing squealing and squeaking. It might be a leak in your ducts or somewhere around the furnace that is causing just enough air to penetrate the system and cause it to squeak or whistle. Check to see if there are any gaps in the ductwork that need to be sealed off.

The furnace is constantly cycling on and off.

Anytime the heating cycles are extremely short, there is an issue with your system. Check to see if the filter needs to be changed. They can easily get clogged from all of the dirt, dust and debris that floats in the air and runs through your system. When the filter is clogged, it will cause the unit to overheat because the airflow is restricted. Changing the filter can correct the problem quickly and allow the air to flow through the system easily.

The blower won't turn off.

When your blower doesn't want to turn off, you might want to start looking at the fan switch to determine whether it is in the right setting. If the fan is set to on, it isn't going to shut off. Turn it to the auto position to get it to cycle on and off properly. Another thing to check is the filter. If that filter is clogged, it can make it where the switch inside of the unit isn't able to sense the proper temperature and doesn't know when to turn off.

In going through the troubleshooting tips above, you can get your unit back in working order in no time.
