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.
