How to Troubleshoot Air Conditioner or Heater Noises

Are you wondering what are those annoying noises coming from your heating and cooling system? Many air conditioner or heater noises are actually fairly simple to fix, especially for the experts at Gainesville’s best heating and cooling company. Here are several of the most common causes of a noisy AC and cures to help you restore the comfort of peace and quiet at home, from our team at A+ Air Conditioning and Refrigeration.

How to Check Your HVAC’s Fan Blades

Open your AC unit’s cabinet and locate the fan to check for any dirt or debris around the blades. It’s not uncommon for insulation or other objects to fall in the unit and cause noise. Also check to see the blade isn’t loose and tighten the screw if necessary.

Need to Repair or Replace Old or Broken HVAC Parts?

If your condenser is an older model, your best bet may be to invest in a new AC unit. While the initial cost may be steep, new technologies are drastically quieter and more efficient, improving your comfort at home and saving you monthly energy bills.

If you have a newer condenser and are still experiencing a racket, the noise is most likely coming from the compressor. You should contact your manufacturer or HVAC professional to find a sound blanket that will help address issues concerning noise.

Check HVAC for Loose Screws, Pests, and Uneven Blades

There are several other smaller issues that could be the root of your noisy AC. Make sure no plate or screw has come loose anywhere on the unit. Check for bugs or small rodents inside the fan or other parts of your equipment. Also ensure that there are no areas of unevenness or bends on the blades.

How to Analyze Specific Heating or Cooling Sounds

It’s important to differentiate between simple and complex problems when it comes to a noisy AC. Here are a few specific sounds to check for, the issues each noise is usually indicative of:
Rattling Noise: Something is loose.
Whistling Noise: Problem with the seals.
Screeching Noise: Problem with the belts.
Thudding Sound: Something is loose or flying around in the unit.
