3 noises that may warn of air conditioning repair needs

Anything mechanical will make noise during operation, but there are differences between good noises and bad ones. When it comes to your air conditioner, some noises are better than others. Dynamic Mechanical Heating & Air Conditioning has heard many different noises through the years, so we’ve taken 3 that you’ll want to be listening for this summer. When you need air conditioning repair in Hartford, CT, Dynamic Mechanical Heating & Air Conditioning is the company to call.


When your air conditioner starts up, you may hear a hissing noise that lasts for several seconds; this is quite normal. However, if you continue to hear that noise, there may be a problem with your compressor. Compressors are one of the key parts of your air conditioning system, so it’s important to have a professional air conditioning technician look at your unit’s compressor.

Screaming Noise

A screaming or screeching noise is also indicative of a compressor issue, and this one can be very serious. Compressors pressurize refrigerant as part of the cooling cycle, in order to help cool your home. If there is a screaming/screeching noise emanating from your outdoor unit, there may be excessive internal pressure in the compressor. Turn your system off immediately and contact a professional right away.


Clunking noises in your air conditioner typically mean something has come loose – but what that something is needs to be determined by a licensed professional.

Clunking can happen when a mount or bearing comes loose. It can also happen when pieces of the fan are bent or break off. No matter what size piece is causing the clunking, it should be repaired quickly by a qualified technician so it doesn’t cause greater problems in your system.

Get the Noise Fixed

Whether your air conditioner is banging, clicking, snapping or clunking, it is always best to call an AC specialist to check it out. It may be something small, like a loose component, but it could be something bigger and potentially more dangerous to your air conditioner and property.
