Few things are worse than an abrupt, loud bang, especially if it’s coming from your air conditioner. If you’ve begun to hear a loud slamming sound when your system goes down, there might be various underlying issues at work. While determining the specific problem without having a professional diagnose your unit might be challenging, there are a few frequent causes that can help you better appreciate whether or not expert repair services are required.

Why Your AC Is Making Noise Even after Shutting Off

If your air conditioner is making noise even when it’s turned off, there are several possible explanations. The most likely culprit is a problem with the compressor, which is the part of the air conditioner that circulates refrigerant. Compressor problems can cause a range of noises, from a gentle humming to a loud, persistent banging.

Other potential causes of noise include loose parts, debris in the air conditioner’s fan, or a problem with the air conditioner’s electrical components. In some cases, the noise may be coming from an adjacent appliance, such as a refrigerator.

If your air conditioner is making noise, the first step is to identify the source of the noise. Once you know where the noise is coming from, you can troubleshoot the problem and take steps to fix it.

Other Common AC Noises and How to Deal with Them

Screeching: If your air conditioner is making a screeching noise, it’s likely due to a problem with the compressor. The most common cause of screeching is a loose or damaged belt. If the belt is loose, you can try tightening it. If the belt is damaged, you’ll need to replace it.

Squealing: If your air conditioner is making a squealing noise, it’s likely due to a problem with the compressor. The most common cause of squealing is a loose or damaged belt. If the belt is loose, you can try tightening it. If the belt is damaged, you’ll need to replace it.

Rattling: If your air conditioner is making a rattling noise, it’s likely due to a problem with the fan. The most common cause of rattling is a loose or damaged part. If the rattling is caused by a loose part, you can try tightening it. If the rattling is caused by a damaged part, you’ll need to replace it.

Hissing: If your air conditioner is making a hissing noise, it’s likely due to a problem with the refrigerant. The most common cause of hissing is a leak in the refrigerant line. If you suspect a leak, you should contact a professional for repair.

Clicking: If your air conditioner is making a clicking noise, it’s likely due to a problem with the electrical components. The most common cause of clicking is a loose or damaged switch. If the clicking is caused by a loose switch, you can try tightening it. If the clicking is caused by a damaged switch, you’ll need to replace it.

Conclusion

There are a few reasons why your air conditioner may be making noise even when it’s shut off. It could be due to a loose component, a build-up of dirt and grime, or a problem with the compressor. If the noise is only occasional, it’s probably not a cause for concern. However, if the noise is constant or becomes louder over time, it’s a good idea to have a professional take a look at it.

Cody is very professional and knowledgeable. He responded quickly to my enquiry. He worked with us to ensure we could set up the ductwork and venting in a way that maximized the basement.

Climate experts came in for HVAC/boiler maintenance when we moved into our new house. They ended up finding a problem that went undiagnosed by our home inspection that could have been very dangerous. They then ended up installing a new boiler for us super quickly. It was obviously a sudden expense but Climate experts made the whole thing feel a lot better due to their professional and concern for our safety. The new boiler not only works, but is...dare I say...beautiful! The copper piping work that they did is a sight to behold. Who knew that we would be so excited to show our family/friends our cool new boiler. We absolutely recommend these folks—they are reliable, professional, and make even the typically boring part of the house feel nice and pretty. You are in good hands with them!
