We rely on our HVAC system to keep our homes comfortable, so hearing noises is cause for alarm for many homeowners. It’s a reasonable reaction, as you don’t want your AC to cut in the middle of a summer heat wave.

However, acting fast and diagnosing the problem can help you fix the issue sooner, so you don’t have to worry about a Tennessee summer without air conditioning. Plus, you won’t have to listen to obnoxious banging, scraping, or grinding. 

These HVAC noise reduction tips will help you fix the issue. 

What’s Causing the Noisy HVAC?

There are many types of HVAC sounds. Sometimes, excess noise is due to a broken part or faulty system. The fix may also be as simple as using duct silencers or other noise-control materials. 

First, you should rule out mechanical issues by troubleshooting your heating and cooling system. Here are some common noises you might hear and what they mean. 

Grinding Noises

Dirt and debris can enter your HVAC system, such as your blower motor or air conditioning unit. Dirt and small objects like rocks can cause friction and make a grinding noise. 

Regular cleaning and HVAC maintenance are crucial to prevent issues like these. 

Clanking or Banging

Bangs, clanks, or rattling noises can indicate a loose part. When something inside your system breaks off, it can rattle around and cause loud noises. 

If the noise is too loud, immediately turn off your system and contact a heating and cooling repair company as soon as possible. 

Rumbling Noises

A rumbling noise might be due to an issue with your ductwork. It’s a good idea to get an inspection to make sure nothing made its way inside. You should have your ducts cleaned if you suspect vermin.

A broken heat exchanger can also cause this noise. 

Dripping Noises

Although this noise isn’t as loud or as common, it can happen. Dripping sounds are usually due to refrigerant leaks. Excess moisture can also cause a dripping noise, as can a clogged or broken condensation drain.

Squealing or Screeching Sounds

One of the loudest and most alarming noises is screaming, squealing, or screeching. This can happen when a fan belt wears down. Your system might also need some lubricant. 

Have an HVAC technician come to take a look and determine the cause.

If your loud HVAC system is due to a mechanical problem, hiring an HVAC tech to perform maintenance is the best way to resolve the issue. So, if you notice any of the above signs, call a repair company as soon as possible. 

Loud air conditioners can also be caused by worn-out padding, meaning replacing the noise-control materials will muffle the sounds coming from your system.
