Furnace Repair – Common Problems That Can Be Fixed by Homeowners

If you’re having furnace problems, don’t wait to contact a professional. Many common heating issues can be fixed with regular service visits and a little preventative maintenance. Our expert HVAC technicians are here to help you get the most out of your home’s heater, keeping it running as efficiently as possible.

Several factors may cause your furnace to stop working properly. A faulty pilot light, thermocouple, or ignitor are just a few of the most common causes of this problem. In most cases, a quick fix will be necessary to keep your family warm and comfortable.

The whirring sound that a healthy furnace produces is a sure sign that all is well. However, if you notice banging, rattling, squealing, or other strange sounds, this could indicate that there’s a problem with the unit. If the issue isn’t addressed right away, it could cause a bigger problem that will require a costly repair.

Furnace that keeps turning on and off

If your furnace constantly cycles on and off, this can be caused by a clogged air filter or a thermostat that’s not functioning properly. It can also be a sign that the high-limit switch has been damaged. To locate the switch, consult a furnace-wiring diagram or your service manual. It is located below the sealed combustion chamber inside the furnace and usually has flexible tubing attached to it.

A burned-out igniter, flame sensor, or blower motor is another reason that a furnace might cycle on and off frequently. Typically, this can be replaced by a DIYer, but replacing the burner head or the blower fan motor is more of a job for a professional.

Another issue that is often caused by a faulty flame sensor or igniter is that the furnace overheats. In order to prevent this, the homeowner will need to clean the blower fan wheel and the indoor vents of dust and dirt. A clogged air filter can also cause the igniter and flame sensor to overheat, so they should be replaced as soon as possible.

Lastly, the carbon monoxide detector should be tested regularly. While it’s not something that homeowners can do themselves, if the detector emits an odor that smells like rotten eggs, this is a sign that there is a gas leak in the home. This is a very dangerous issue that should be dealt with immediately by calling the gas company and emergency services.

In addition to the above, it is important to regularly vacuum the area around your furnace and clean the ductwork and pipes leading up to it. A regular maintenance schedule will help ensure that your furnace runs properly, which can increase its life expectancy and minimize energy costs.
