What Should You Know About Repairing Your Furnace?

Furnaces are essential pieces of equipment for home comfort, especially during cold winter months. While furnaces are designed to last many years, they will eventually require maintenance and repair. Knowing when to repair your furnace can prevent costly breakdowns and potentially dangerous malfunctions.

Furnace repair is often necessary when the system is not working properly. Signs that indicate it’s time for a repair include:

Poor Indoor Air Quality

If you have poor indoor air quality, this could be due to various problems. The most common reason for poor indoor air quality is an overly dusty filter or dirty vents and ducts. If you are experiencing this issue, it is highly recommended that you have your furnace serviced at least once yearly.

Heater Frequently Cycles On and Off

When the furnace cycles on and off frequently, this is usually a sign of an issue with the temperature control. This can be caused by a faulty thermostat or defective wiring or control board. You should have your system inspected by a qualified heating expert if it’s cycling on and off frequently.

Thermostat Is Inaccurate

If your thermostat is inaccurate, this can cause your furnace to run longer than it needs to or not turn on at all. A faulty heating system or thermostat can cause this problem. To troubleshoot this issue, you should check the batteries in your thermostat first and then have an HVAC technician come out for an inspection.

Dirty or Clogged Furnace Filters

A dirty or clogged furnace filter can cause your heating system to run longer. This problem can be caused by a clogged air filter, which blocks airflow and reduces your furnace’s efficiency. To troubleshoot this issue, you should check all of the filters in your home and ensure they’re clean and not blocked by debris.

Increased Utility Bills

If your heating bills are higher than normal, it could indicate a problem with your HVAC system. To troubleshoot this issue, you should have an HVAC technician come out for an inspection to determine if there’s anything wrong with the system or components.

Loud Noises or Vibrations When Running

If your furnace makes loud noises or vibrates when it runs, it may be time for repair. This could indicate something wrong with the blower fan or motor assembly. It could also mean that the bearings for your blowing fan are worn down and need to be replaced.

Problems with the Blower

The blower is part of your furnace that distributes air throughout your home. It’s one of the most important parts to maintain because if you don’t, it will affect how your entire HVAC system operates. Check the blower motor to make sure it’s running properly. If it doesn’t seem to work, you may want to consider replacing the fan motor assembly. Also, check your condenser or fan belt if the problem persists.


It can be challenging to determine when it’s time for furnace repair. However, if you experience any of the above issues, your system likely needs to be repaired or replaced. It is important to keep your furnace in good working order. Not only will it help keep your home warm during the cold winter months, but it can also save you money on utility bills. The sooner you recognize a problem with your furnace, the better.
