3 Most Common Furnace Problems and How to Fix Them

Furnace Problems

There’s nothing worse than coming home on a cold winter day to a furnace that isn’t working. Not only is it inconvenient, but it can also be dangerous. So, what can you do to avoid this nightmare scenario? The good news is that most furnace problems are relatively easy to fix as long as you know what the issue is. Here are three of the most common furnace problems and how to fix them.

1. Dirty Filters

One of the most common furnace problems is dirty filters. When the filter gets clogged with dirt and dust, it restricts airflow and makes the furnace work harder to circulate air. This can lead to a number of problems, including decreased efficiency, increased energy bills, and even premature wear and tear on the furnace.

The best way to avoid this problem is to change your furnace filter regularly. You can do this by hiring a professional technician for HVAC in Sandy Springs to do it for you. They will be able to tell you how often the filter should be changed based on the type of furnace you have and the level of use.

2. Noisy Furnace

If your furnace is making strange noises, it could be a sign of a bigger problem. For example, banging, squealing, or humming noises can indicate that there is something wrong with the blower motor or the fan belt. However, if you hear popping or crackling noises, it could be a sign of something more serious, like a gas leak. If you hear any of these noises, it’s best to turn off the furnace and call a professional to take a look. They will be able to diagnose the problem and make the necessary repairs.

3. Thermostat Issues

If your furnace is running but not heating your home, the problem could be with the thermostat. First, check to make sure that the batteries are working. If they are, then the problem could be with the wiring or the furnace itself. The best way to figure out what the problem is will be to call a professional. Apart from this, you may also check out why your furnace keeps turning on and off so that you can fix it accordingly. Remember that it is always best to let a professional handle any repairs or replacements that need to be made to your furnace.


These are just a few of the most common furnace issues that homeowners face. By knowing what the problem is, you can take the necessary steps to fix it. However, if you are still having trouble, it’s best to contact a professional. They will be able to diagnose the issue and get your furnace up and running in no time.
