5 Strange Noises from an HVAC in Mt Pleasant, SC You Should Never Ignore

Your HVAC (Heating, Ventilation, and Air Conditioning) system is designed to keep your home comfortable, but sometimes it can develop strange and alarming noises. While you may want to overlook these sounds, they can lead to costly repairs or even a complete system breakdown. Here are five strange noises from your HVAC in Mt. Pleasant, SC, that you should never ignore:

Banging or Clanking

If you hear loud banging or clanking noises from your HVAC unit, it’s a sign that something is seriously wrong. These sounds may indicate a loose or broken part, such as a:

  • Blower wheel
  • Fan blade
  • Compressor

Ignoring these noises can lead to further damage and reduce the lifespan of your system.

Hissing or Whistling

Hissing or whistling sounds typically suggest air or refrigerant leaks. Leaking refrigerant can harm your system’s efficiency and may be detrimental to the environment. Air leaks can affect your home’s comfort. Address these noises promptly to avoid higher repair costs.

Squealing or Screeching

High-pitched squealing or screeching noises often originate from worn-out or misaligned fan belts. Continuously running your HVAC with damaged belts can lead to overheating and decrease efficiency. It’s relatively simple and cost-effective to replace these belts.

Clicking or Tapping

Clicking or tapping sounds can result from electrical issues within your HVAC system and can include problems with:

  • Relays
  • Contactors
  • Control boards

Ignoring these sounds can lead to electrical failures and potential fire hazards.

Gurgling or Bubbling

Gurgling or bubbling noises indicate air or water trapped in your HVAC system’s refrigerant lines. This issue can impair the cooling or heating process and reduce efficiency. Address these issues promptly to maintain your system’s performance.
