Why Is My A/C Making Weird Noises?

Having a working air conditioner in the summer is a must to keep your family comfortable. Even if you change your HVAC filter often and have your unit serviced each year, you can’t stop all problems. If you hear a weird noise coming from your air conditioner, find the problem as soon as you can.
When your HVAC unit starts up or shuts down, you’ll hear a familiar clicking noise. That’s a completely normal noise to hear. If you hear a clicking noise when the unit is running, it could mean that you have a defective thermostat. Contact an HVAC professional to check for electrical malfunctions in your air conditioner.
It’s natural to hear a low-pitched pulsing noise from your air conditioning unit. If the noise is louder than normal, it’s a sign that there’s a loose part inside of your air conditioning system. Some common culprits of this noise include loose fan blades and panel covers. If you can’t tighten the loose part causing the pulsing noise, call an HVAC professional. They can help you tighten the part and fix other problems they find.
Another distinct noise that can alert any HVAC homeowner of a problem is a rattling noise. This means that there is debris clogging your system. It’s best to turn it off and clean out any loose debris. If the noise is still there when you turn your air conditioner back on, call in an HVAC professional to help.
Another common air conditioning unit noise that indicates a problem is squealing. This is a result of a fan motor going bad. You should have the noise evaluated by an HVAC professional now. This way, they can replace the fan motor, if necessary, before it goes out in the middle of the summertime heat.
If you notice a humming noise from your air conditioning unit, it’s a sign that something is likely loose. Loose parts or piping can cause vibrations inside the air conditioning unit. Have this humming noise checked out by an HVAC professional sooner rather than later. The longer you let a loose part go, the more expensive it’s going to be to fix in the future. It can damage other parts of your HVAC system.
One of the scariest noises that your air conditioning unit can make is a banging noise. When this happens, one of the parts inside of your HVAC system broke or is very loose. You should turn off your air conditioning unit and look for any out-of-place HVAC parts. If you’re unfamiliar with the parts of an air conditioner, call an HVAC professional to help you.
One very annoying noise that your HVAC system can make is a high-pitched scream. This screaming noise is likely caused by a refrigerant leak in your HVAC system. It’s important to note that refrigerant can be dangerous to your respiratory health. If you start to hear a distinct high-pitched screaming noise from your HVAC unit, it’s time to turn it off. Call in an HVAC professional to check your air conditioning unit.
