Have there been banging, rattling, squealing, hissing, clicking, humming, buzzing, or grinding noises in your home? Do these noises seem to be present every time you use a part of your extensive HVAC system? Have you spent the last few days or weeks wondering, “Why is my AC making noise?”
If any of these questions describe you, you’ve come to the right place. There are many possible reasons why your AC is making noise. Let’s take a closer look at five possible answers to your question, “Why is my AC making noise?”
Why Is My AC Making Noise? 5 Sources
The unusual noises produced by your AC are, more often than not, signs that there is something wrong with your AC unit. Those noises could be attributed to any of the following causes.
If you hear sounds like banging, grinding, or squealing, there’s likely a problem with your AC’s compressor. The compressor distributes refrigerants and removes extra heat from within your home. Parts coming loose inside the compressor are what lead to a banging or squealing sound from your AC. When this happens, it means it’s time to replace this part of your AC unit.
Conversely, the squealing sound can be attributed to the pressure being too high in your compressor. If this is happening, turn off your AC and contact an HVAC technician as soon as possible. Finally, if there’s a grinding sound coming from your AC compressor, it means the compressor itself is defective and needs to be replaced.
The fan motor could be experiencing difficulties if the sounds from your AC resemble screeching, buzzing, or clanking. Screeching from your fan motor could be due to the fan blades becoming faulty and needing replacement. The buzzing is likely your AC trying to tell you that the fan motor is faulty. Finally, clanking or repeated clicking are both possible signs that the AC fan is loose or its blades are loose and need to either be replaced or tightened. Loose fan blades could lead to damage to other parts of your AC if left unaddressed.
One of the most common answers to the question, “Why is my AC making noise?” is excessive debris buildup. You’ll usually hear your AC unit producing noises like banging, rattling, or buzzing when the debris is stuck in a part of the unit. If you’re able to reach the parts where debris buildup is present safely, you can take care of it yourself.
An air duct leak is a problem that should be addressed when you hear any hissing from your AC. The leak could be caused by a malfunctioning part, or it could be a sign that your air filter is incompatible with your HVAC system. Whatever the cause of the leak may be, have a professional take a closer look at the source of the hissing.
5. Loose Parts
Loose parts within your HVAC system are another possible response to “Why is my AC making noise?” The loose parts can be found anywhere in your HVAC system, consequently producing any number of sounds. For example, screws could come loose on either indoor or outdoor units, which might lead to a banging noise; a loose coil can also be the source of a pulsating noise in your home.
