Why Is My AC Making Weird Noises

When the hot summer months come around, your air conditioner is a vital part of your family's comfort. Unfortunately, unexpected noises can happen. Being able to identify them early can help you to avoid costly repairs in the long run. Start by taking a second to identify the noise that your HVAC system is making.

1. Banging

If you notice a banging noise coming from your air conditioner, it's a sign that there is a broken or loose part. This could be a crankshaft, piston pin, or even a connecting rod. It's best to shut your HVAC system off and contact an HVAC professional to check out the noise.

2. Clanking

When you hear your HVAC system make a clanking noise, it's likely that a part is loose or out of balance. It's not uncommon for an indoor blower fan to become unbalanced and hit other parts. When this noise occurs, it's best to shut off your HVAC system. Contact an HVAC professional for further help with the issue.

3. Clicking

The electrical parts of your air conditioning system will click when they turn on and off. If you hear a clicking noise while your system is running, it's a sign that something is wrong. The most likely culprit is a defective thermostat. It's best to contact an HVAC professional for a whole HVAC system evaluation.

4. Buzzing

A buzzing noise coming from your air conditioning unit can be from many things. There could be loose parts, loose debris in your HVAC unit, a refrigerant leak, or even a failing part. You may want to contact an HVAC professional to identify the source of the buzzing noise.

5. Rattling

Rattling is one of those noises that can mean a variety of issues with your air conditioning system. It could be as simple as debris caught inside of your system or a loose bolt. Or, it could be as serious as a deteriorating air conditioning system. An HVAC professional will listen to the rattling to find where it's coming from and what's causing it.

6. Screaming

A high-pitched screaming noise from your air conditioner is likely a refrigerant leak. It's vital that you shut off your air conditioner and contact an HVAC professional right away. Your HVAC professional may be able to find a refrigerant leak. It can also be an internal pressure problem with the compressor in your air conditioner.

7. Pulsating

A slight pulsating noise from your air conditioning system is completely natural. But, it can sometimes be a sign that there's a problem. If the outdoor unit is pulsating sou loud that you can hear inside the home, it's a loose part in your condenser unit. You should contact an HVAC professional for help with this noise.

8. Humming

A humming noise from your HVAC system isn't usually a sign of anything serious. Rather, a humming noise is a sign that there's a loose part inside of your air conditioning system. While you can still run your HVAC system, it's a good idea to contact an HVAC professional. They can look at the problem and fix it before it gets worse. You want to prevent costly damage to your air conditioning system.

9. Squealing

A squealing noise from your air conditioning system is often a result of the blower fan. As the fan motor starts to wear out, it will start to squeal. It's best to have your local HVAC professional check the fan. They will know if you need a replacement motor for your air conditioning system.
