Furnace Problems: 6 Most Common HVAC Problems

You probably don’t give your furnace much thought until it stops working. 

The good news is that many furnace problems are easy to correct. 

While it’s advisable to hire a professional when your furnace isn’t working correctly, there are some issues that you may even be able to fix yourself.

Keep reading to learn about the six most common furnace problems.

Dirty Filters

Replacing your filter regularly is one of the most important things you can do to extend your furnace’s life and efficiency. 

A clogged or dirty filter is one of the most common furnace problems. 

Clogs and blockages prevent air from circulating properly. 

This forces the system to work harder and often results in inadequate heating. 

To keep your furnace in good working order and to ensure maximum efficiency, replace your filter monthly.

UNUSUAL FURNACE NOISES 

Some furnace noises are part of regular operation, while others may be a warning or indication of a mechanical problem. 

A whining or squealing motor can indicate that the bearings in an inducer motor or blower motor are failing.

Either way, it is best not to ignore these signs as they may warn of a dangerous operating condition or lead to a furnace failure.

Mechanical Wear and Tear

Over the years, your furnace experiences a considerable amount of wear and tear. 

Furnaces are made up of numerous components, and if one stops working correctly, the entire unit can break down. 

From overheating to airflow problems and more, mechanical wear and tear can lead to numerous problems with your furnace.

Pilot or Ignition Control Issues

Pilot and ignition control are two of your furnace’s most essential components.

If they malfunction, heating your home will be next to impossible.

Malfunctioning Thermostat

The thermostat is the device responsible for determining when heat needs to be produced and how much heat is needed. 

When the thermostat isn’t working properly, heat may not be produced and circulated throughout your home. 

A malfunctioning thermostat could also cause your furnace to produce too much heat.

Lack of Maintenance

Regularly scheduled maintenance by a licensed service contractor is a MUST to keep your system in proper working order.

Many of the most common furnace problems can be avoided with proper maintenance by a certified service contractor. 

Without regular maintenance and inspections, your furnace is prone to breakdowns and poor performance. 

You could also see increased energy costs as the result of failing to maintain your furnace.
