Is there a funny noise coming from your air conditioner?

When your air conditioner is on and working properly, you’ll probably hear it, but it will be quiet and easy to tune out. On the other hand, if your air conditioner is making an unusual noise, like a rattling or hissing noise, then it might be time to get air conditioning repair in Granbury. At Apex Home Energy Savings, our goal is to keep you comfortable and help you save energy, and one of the best ways we know how to reach that goal is to provide you with the prompt repairs that you need. The first step to providing you with the right repair or service is to identify the problem. Here is our list of the most common air conditioning noises and they might mean:

#1. Buzzing

If the buzzing is very low, the problem probably isn’t too serious, but in most cases, when you hear a loud vibrating or buzzing noise, it typically means that your unit has an electrical issue. A loud buzzing could mean that there are loose wires, a broken contactor relay switch, a broken condenser fan motor or a tripped circuit breaker.

#2. Hissing

Do you hear a high pitched screaming or hissing noise when you first turn your air conditioner on? If so, there may be an excessive amount of pressure building up in your air conditioner, which causes the compressor to start hissing. This buildup of pressure can be very dangerous, so it’s important to turn off your air conditioner and call in an expert to get it repaired right away.

#3. Banging

Banging is a sign that your air conditioner has a broken or loose part inside of the compressor, usually a connecting rod, crankshaft or piston pin. A banging noise could also indicate that the fan in your air conditioner is hitting something, like a stick, or that the fan itself has come loose and is wobbling around.

#4. Squealing

Have you noticed a squealing noise that comes and goes from inside of your unit when it is on and running? This could indicate that your fan belt is either worn down or misaligned. This belt connects the motor to the fan, and it can become misaligned or wear down over time. Different temperatures and humidity levels cause the belt to contract and expand, which is why the squealing noise comes and goes.

#5. Clicking

  • If your unit is running – If there is a clicking noise coming from your unit while it’s running, it might be a sign that there is a small object stuck in the fan, but it could also be a sign of an electrical issue.
  • If your unit won’t start – If you hear a clicking noise when you try to start your unit, and it won’t turn on but continues to click, then there is probably an electrical issue, most likely a problem with the compressor, thermostat or capacitor.

#6. Gurgling or Bubbling

A bubbling or gurgling noise is almost always a sign that you have a refrigerant leak somewhere in your unit, most likely in the evaporator coil or refrigerant line, although it could also indicate an issue with the condensate drain line.

#7. Screeching

Does your air conditioner make a loud screeching sound, much like metal on metal, when you turn it on? If so, it could be a sign that the fan motor bearings are no longer reliable, which means that you’ll have to have the fan motor replaced.

As you can see, air conditioners make many noises that indicate the need for repair, but regardless of the noise that your unit is making, Apex Home Energy Savings can help. Schedule your appointment today!
