Why Is My Air Conditioner Making Noises?

You might be wondering why your air conditioner is making strange noises. There are reasons for this, but a basic tune-up quickly addresses most. Not dealing with these issues could end up costing you more money than you'd have spent on the unit in the first place. If you're not sure why your air conditioner is making noise, here are some common causes. These causes range from simple noises to more complicated problems. Some causes include:

Faulty Thermostat

One cause is an improperly functioning thermostat. The reason for this could be electrical or mechanical problems. The rattling can be either continuous or intermittent. In some cases, an unbalanced thermostat could be to blame. However, if the noise is only intermittent, then the cause might be something more serious.

A noisy fan can be the result of worn-out fan parts or an electrical issue. It's also a sign that your system's thermostat is out of balance. If the noise continues, it may be time to consider an AC Replacement. If your AC Repair Tampa is still making noise, call a professional to assess the problem.

Clogged Fan

Another common cause of these noises is a clogged fan. Depending on the cause, this noise may be due to the fan motor's failure or the compressor. Ice builds up in the air conditioning system during this process, resulting in a buzzing or pulsating noise.

Similarly, water could be causing the sound, and you should address these reasons by contacting a professional as soon as possible. In addition to dirty air filters, excess condensation and a malfunctioning thermostat can also be the culprits.

If you hear the noise, it's most likely a problem with your air conditioner. To fix the problem, contact an expert HVAC technician. If you can't find the problem, have the unit inspected. It's vital to diagnose the cause of the noise to avoid a costly AC Repair in the future.

Air Condition Leaks

If your air conditioning unit is leaking, you should contact a professional immediately. A qualified technician from a reliable HVAC repair company such as Momentum AC can fix the noises. The sound of an air conditioner can be a sign of a more significant problem. It may need to be repaired or replaced if you don't notice any problems right away. If it's a rattling sound, this is most likely caused by a loose fan blade.

Malfunctioning Component

Loud noise can be a sign of a malfunctioning component. The most common reason for an air conditioner making noises is a motor that is out of balance. If this happens, you should repair the problem to stop the sound.

If you cannot afford to replace the compressor, you can buy a new one. If the fan is out of balance, it can cause noises. If the air conditioning system is making a loud noise, it is probably a loose component.

You can usually fix this problem yourself with some simple DIY steps. If the noise persists, call AC technician from Momentum AC for a quick diagnostic and solution. Your technician can pinpoint the exact cause of the problem and suggest what to do next. Once you have identified the root cause, your AC can work properly again. There are several possible causes of noisy air conditioning.

Damaged Motor

Whirring noises may be a sign of a damaged fan motor that can cause these sounds. An air conditioner that makes this noise should be checked by a professional. If the noise continues after the compressor is repaired, it may signify a refrigerant leak.

The most common cause of whirring noises is a loose fan belt or a damaged fan. Often, these sounds can be caused by debris that has gotten into the outdoor fan unit or by a malfunctioning fan motor.

In the process of air conditioning repair, the position of the elements of the fan should be among the first things to check. This can cause more significant damage down the road. If it's coming from the thermostat, the problem is likely with the motor.

If so, you can contact an experienced HVAC technician from Momentum AC for assistance. In some cases, the noise can be due to loose parts, ice, or debris. The AC's shutoff sensor could be triggered by high pressure inside the compressor, which can cause a loud banging sound. If you hear squealing or screeching sounds, you should contact a qualified HVAC service technician as soon as possible.


When you notice an air conditioning noise, please do not ignore it. In most cases, it's nothing to worry about, but ignoring it can cause costly repairs. While the buzzing and humming noises are relatively familiar, you should immediately shut down the unit if you hear them frequently or notice them in varying volumes. If you can't locate the source of the sound, call a professional to investigate.
