5 Important Considerations With a Noisy AC Unit

October 6, 2020 - Published by Scott's Air

According to Air Conditioning, Heating and Refrigeration NEWS, a noisy air conditioner is a sign that your A/C is not working properly. From simply removing debris from your fan to large repairs and A/C unit replacements, a noisy A/C can be fixed in a variety of ways. However, knowing what is causing the noise may help you in the future by diagnosing problems much earlier on. Here are five important considerations for when you have a noisy AC unit.

Are You Overworking Your Air Conditioner?

One of the easiest ways to reduce the lifespan of your A/C unit and cause unnecessary repairs is to keep your A/C running constantly. When you have the A/C unit set to “On”, instead of “Auto”, you not only cause wear and tear on A/C parts, but you are also significantly increasing your electric bill.

If your A/C is on “Auto” and is still running constantly or cycles on and off repeatedly, it may mean any number of issues including dirty air filters or coils, leaking refrigerant, faulty controls, holes in the ducts or a number of other reasons. These are easily fixable through a maintenance visit from your trusted A/C company.

Your A/C Unit Isn’t Right for Your Home

If you have just installed a new A/C and notice it being noisy or have spent months with a noisy A/C, it may mean that the unit that you purchased may not have been the best fit for your home. It’s possible that your unit isn’t the correct size for your space or that you may have purchased a lower cost unit that lacks noise reduction technology.

You will need to bring in an air conditioning system design professional to assess your home’s needs. They will be able to tell you exactly what size unit to use and may even provide ideas for reducing potential sound in the future such as noise buffer zones and duct redesigns.

Are You Hearing Whining or Hissing?

A whining, hissing or whistling sound is typically caused by airflow or air pressure issues. It may require an inspection to identify the culprit, but it is usually fixable in a simple maintenance visit. Here are some of the possible problems:

You have a duct leak
Air filters are clogged or improperly installed
There is a hole in your ducts or improper ventilation design
The expansion valve may need a repair

Regardless of the reason, if you are dealing with a noisy A/C unit, you should call the experts at Scott’s Heating and Air Conditioning to come take a look. Don’t let a simple repair turn into a system replacement because of neglect.

Are You Hearing Rattling or Shaking?

Hearing a shaking sound coming directly from your air conditioning unit? Then you may have a damaged fan motor or the unit itself may not be stabilized to the surface it sits on. Remember, air conditioners are machines that have electricity running through them. If you are experiencing rattling or shaking with your A/C unit, call a trained professional to fix it.

Are You Hearing Screeching and Squeaking?

If you are hearing a loud screeching or squealing sound, it’s best to first identify exactly where it’s coming from. If you are hearing it from your outdoor condenser unit, then you either have a bad compressor or a faulty fan motor. If the screeching is coming from inside the house, then the primary culprit is the blower fan motor. You may need replacement parts, part adjustments or simply just need to lubricate the motor shaft bearings.
