Anytime your AC kicks on, you would naturally expect a certain level of noice to come with it. However, if your AC kicks on and you all of a sudden hear noises that you know aren’t normal, you more than likely have a problem that needs to be dealt with. There are a number of different problems that can result in AC noises. Hal Mechanical is here to talk about what the causes of strange, loud AC noises can be.
Parts of Your AC that Can Be the Cause of Strange Noises When Broken
Because there are so many working parts on your AC system, there are many things that can go wrong. A lot of the time, when there is a problem, it will present itself with a loud noise that is different than the normal everyday AC noise. Here are some of the different parts that can have problems and cause strange noises as a result.
– Faulty Belts: When there is a belt in your AC unit that has gone bad, a common noise that will be a result is screeching or squealing. This can also indicate a problem with the motor as well.
– Condenser: A loud banging noise is something you never want to coming from your AC unit. A lot of the time, this is a problem with your condenser. It can be a result of dirt and dust accumulation, a broken fan motor, or loose screws.
– Clogged Condensate Drain: There is a drain that gets rid of the moisture that is removed from the air inside your home. When there is a clog in that drain, the water will slowly start to accumulate and will cause problems with the entire unit. This can cause a pulsating sound that is frequent as the motor attempts to boot up and fails over and over again.
– Refrigerant Leak: The refrigerant in your system is necessary to keep your home cool. The only time that your refrigerant would be running low is if there is a leak somewhere. When you have a leak, it can be accompanied with a hissing noise since this refrigerant is located in high pressure pipes.
– Fan Issues: Clicking noises can often happen when there is a problem with your fan. Either you have something that is getting in the way of the fan operating, or the blower motor that moves the fan could be malfunctioning as well. Sometimes, this can happen when the fan is loose and it simply needs to be tightened as well.
