3 Common Furnace Problems And Their Repairs


Furnaces are some of the most reliable home appliances, but sometimes the need for furnace repair can arise unexpectedly. Understanding the most frequent furnace issues that homeowners experience will help you know when it's time to call an HVAC professional. Here is a guide to three common furnace problems and how they are repaired.

1. Low Furnace Heat

Have you ever noticed that the air from your vents isn't as warm as it should be? Low furnace heat is a problem that HVAC technicians are familiar with, although the cause isn't always what you might expect. The air from your furnace may be too cool because outdoor air is mixing in through a leak or because of a problem with the thermocouple, flame sensor, or gas supply.

An HVAC technician can pinpoint the problem that is keeping your furnace from heating. Technicians can replace faulty components or locate and patch leaks in ducts hidden behind your walls. If you have never had a professional furnace inspection, your HVAC contractor can ensure that your furnace is the right size for your home. An undersized furnace won't provide the heating your home needs, and the air from your vents will feel lukewarm.

2. Noise While Furnace is Running

When you use your furnace, the only sound that should come from it is the sound of the blower motor. A furnace suffering from advanced wear and tear may produce unusual and alarming sounds while it's running. Screeching sounds and mechanical grinding noises are two of the most common homeowner complaints.

The best way to solve the problem of a noisy furnace is to hire an HVAC professional. A technician can determine the exact cause of the noise and service the part as needed. Worn bearings and an imbalanced blower motor are two likely culprits behind furnace noise.

3. Furnace Fails to Ignite

Most furnaces won't start at all when there is a problem with the ignition sensor or pilot light. Older models will sometimes run the blower even though the burner doesn't heat up. If this is the problem, you may hear a clicking sound when you try to use your furnace as it attempts to ignite.

You will need the services of an HVAC professional to determine exactly where the problem lies when your furnace won't ignite. While the solution may be to replace the ignition sensor or pilot light, it's also possible that your furnace isn't receiving enough gas. Your technician can inspect the gas line and ensure that there are no leaks or blockages.

Keep an eye out for these furnace problems so that you know when to call for professional furnace repair.
