Are you wondering what those annoying noises coming from your heating and cooling system are? Many air conditioner or heater noises are actually fairly simple to fix, especially for the licensed technicians at Gulfshore Air.

Here are several of the most common causes of a noisy HVAC system and fixes you might try to help you restore the comfort of peace and quiet at home.

*Please note: Today’s heating and air conditioning systems are complex machines and the risk of damaging your system or voiding your warranty can occur if not serviced properly by a licensed HVAC technician. Also, the possibility of electric shock can occur. First and foremost, if you have any question at all about working on your system yourself, call a professional HVAC technician like the ones at Gulfshore Air.

How to Check Your HVAC’s Fan Blades

First, turn off the power at the breaker to your system. Then, 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 into 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 HVAC system. While the initial cost might be higher, new technologies are drastically quieter and more efficient, improving your comfort at home and saving you money on your monthly energy bills. If you have a newer system and are still experiencing noise, the noise is most likely coming from the compressor. You should contact your manufacturer or HVAC professional to find a solution to help address issues concerning noise.

Check HVAC for Loose Screws, Pests, and Uneven Blades

There are several other smaller issues that could be the cause of your noisy HVAC system. 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 HVAC system. 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.
