HVAC Noises You Shouldn’t Ignore

Your heating and cooling system is a complex machine that has a lot of different parts to it. When everything is operating at peak efficiency, it should only make a quiet humming as it blows the air out. If you have any unusual sounds coming from the machine, this could be a sign that something is wrong. Don’t ignore any HVAC noises! This could be a costly mistake.

Looking to troubleshoot before you call our team of experts at Specialty Heating and Cooling? Here are some of the most common sounds and what they could be trying to tell you.

Clanking, screaming, or banging:
Over time, parts inside your machine can become loose, become disconnected, or fall off. This could cause a clank or banging sound. Screaming noises are sometimes caused by refrigerant leaks or too much pressure in the compressor.

Screeching:
Metal on metal is never a pleasant sound. This could also indicate something is wrong with a broken belt, or a motor part. These are things that you should have a professional look at.

Humming:
This might indicate a loose wire or something else that could be wrong with the electrical portion of the machine. If you suspect something wrong with the electrical components, don’t use the machine. This could not only damage the machine further, but it could also be a fire hazard.

If there are any odd sounds or smells coming from your HVAC machine, don’t ignore them. Pay attention to what they are trying to tell you and be proactive by contacting our team of professionals at Specialty Heating and Cooling.
