Odd AC Noises and What They Mean

covering-earsAir conditioners have come a long way from what they used to be a few decades ago. Older AC models used to provide you excellent cooling to keep indoor temperatures in your home cold and comfortable. Unfortunately, they also made a lot of unnecessary noise to do their job. The latest models are a lot more energy-efficient and generate little to no noise while doing a better job of keeping your home cool.

If you hear any strange noise that you shouldn’t from your air conditioning system, it might be a good idea to schedule services for air conditioning repair in Norwalk, CT. Each odd sound can indicate a different problem, and understanding the problem can help you determine the best course of action.

This post will tell you about the odd AC noises and what they mean to help you make a more well-informed decision about AC repairs.

Odd AC Noises And What They Mean

Here is what the sound you’re hearing might mean.

1. Rattling, Thumping, or Banging Noises

A rattling sound coming from your AC could be a sign of several possible problems. If you can hear it all around your house, it is probably a problem with the ductwork. Rattling, thumping, or banging sounds coming from the condenser unit might be a sign that there is a part that has come loose and is knocking against the sides. Turn off the AC and schedule repair services immediately if you notice this problem.

2. Hissing Sounds

A hissing noise from your AC means that there is a refrigerant leak. It could be a leak in the line or coil that is letting all the refrigerant out. You need to call in a professional to examine the source of the leak and fix the problem before the leak becomes worse.

3. Buzzing Sounds

If you can hear a strange buzzing sound from your AC, there might be a significant electrical problem. This sound can come from loose wire or problems with the contactor relay switch or condenser fan motor. You should immediately contact an HVAC company if you hear any buzzing sounds.

4. Clunking Noises

Older air conditioner models make a wide range of sounds. Clunking sounds typically used to happen when their motors needed lubrication. Modern ACs should not make such sounds. If you hear clunking noises from your AC, it could be a sign of several possible problems that you should call a professional to fix.

5. Clicking Noises

Clicking is a noise that you actually should hear when your air conditioner starts and when it stops. It shouldn’t be a loud noise and it should only happen at these two times. If you hear clicking that occurs nonstop, then it’s indicating an issue with your air conditioner’s electrical system.
