Common AC Noises and How to Fix Them

Being a homeowner comes along with the responsibility of taking care of the various systems throughout your entire home. Your air conditioning system is one of the most important systems to keep in operation for your family’s comfort throughout the long summer months. If you’re starting to notice an unusual noise coming from your air conditioning system, it’s vital to address the problem right away before it gets worse.

1. Hissing

If you notice a hissing sound coming from your air conditioning system, it’s important to shut it off right away. This sound is most likely a refrigerant leak, which could be dangerous to your family. It’s best to call in an air conditioning professional right away to get the leak repaired before the refrigerant leaks out into your home. Premier Indoor Comfort Systems in Whittier is the right call to make for all of your home climate comfort needs.

2. Vibrating

If you consistently hear a vibrating noise coming from your air conditioning system, it’s likely an indication of a loose part. When some of your air conditioning components start to deteriorate, they loosen up. It’s vital to get this issue fixed in a timely manner. Otherwise, the loose part can eventually break off and end up damaging other components of your air conditioning system.

3. Screeching

Another familiar sound that homeowners experience from their AC system is a screeching noise. This typically indicates a malfunction with one of the fan motors in your system. In most cases, it’s the blower fan inside the indoor unit or the blower fan inside the outdoor condenser unit. It’s best to shut your system off and have an air conditioning professional fix your broken fan before running your system again.

4. Clicking

It’s completely natural to hear a clicking sound when your air conditioning system first turns on and when it shuts off. However, it should not be clicking while it’s running. If you hear a constant clicking sound from your air conditioning system, it’s an indication that there’s a problem with the electrical system. It’s best to turn off your air conditioning system and get help from a licensed air conditioner professional, such as Premier Indoor Comfort Systems.

5. Buzzing

One sound that may confuse you is a buzzing sound coming from your air conditioning system. The reality is that a buzzing noise could indicate a number of different problems. These include loose parts, excess debris inside of the unit, a pest infestation, or even a clogged filter. Most of these problems you can run through and check on your own. However, if you’re still having issues with a buzzing noise after you check your AC out, and you’re not sure what’s causing it, it’s best to call in a professional to handle the situation.

6. Chirping

If you hear a distinctive chirping sound when your air conditioning system is running, it’s likely an indication that there’s too much friction being created in between parts in your system. When there is a lack of proper lubrication between air conditioning components that work together, they can make this chirping sound. Some of the most common culprits include dry motor bearings, worn-out fan belts, and a fan rubbing against the blower cage or coil. It’s highly recommended to contact a professional to handle this issue to ensure that it’s gets taken care of correctly.

7. Banging

One of the most alarming sounds that you may hear from your home air conditioning system is a banging noise. This is particularly prominent and indicates that there is a broken or loose part inside of your system. It’s essential that you turn it off right away to prevent further damage to your AC system. The most likely culprits are your piston pin, connecting rod, or crankshaft inside of the compressor. It’s likely that you’re going to want to hire some professional assistance to help with this alarming issue.

8. Rattling

When various components of your air conditioning system start to deteriorate and loosen up, they can create a distinctive rattling or chattering noise. If your system is fairly new, you can still experience these sounds, but they’ll be from a different source. These can include a clog in your system, a loose fan, or a malfunctioning electrical component of your AC system. Due to a large number of potential causes of a rattling or chattering noise, it’s highly advisable to seek professional assistance to identify the cause of the noise and fix it.
