While it’s common for your furnace or air conditioner to make noise while it’s running, it’s important to keep an ear out for strange noises that could indicate that something is very wrong. While you may not know exactly what the problem is, when you hear a strange or loud noise, it’s important to call a licensed heating and cooling expert right away. At Enix Mechanical, we can inspect and diagnose any HVAC noise and provide the necessary repairs so that your system is running properly in no time. In this blog, we’ll cover some of the noises you might hear and what they can mean for your furnace or AC.

Metal on Metal

There are seemingly countless metal parts in and on your HVAC systems, and if you hear what sounds like metal scraping on metal, it’s best to shut the system off right away. This sound can often mean that something has come loose and is grinding or scraping on another part, which can lead to significant malfunction and costly repair bills. It could be a blower wheel or a broken motor shaft, and if the system is left on, your furnace or AC could be seriously damaged.

Screeches and Squeals

As your HVAC systems get older, they can be prone to more noises, including screeching and squealing. These noises often mean that a belt or bearing is out of alignment, and without prompt and professional maintenance, that belt or bearing could break or come loose, putting an end to proper unit operation. Our team can quickly and correctly replace any fault parts and get your system running as it should.

Knocking and Thumps

Some furnaces, especially older ones, will turn on and off with a thump or a thud, and this can sometimes be attributed to a change in pressure inside the ductwork. However, if the system continues to knock or thump during operation, it could be an indicator that something is wrong. The vibration damper could be faulty, or another part may have come loose and is knocking against its housing. Whatever the case may be, the Enix team can inspect your system, find the problem, and replace the faulty or broken parts.
