5 Common Ductless AC Noises and Their Causes in Manassas, VA

A ductless AC system offers a convenient and affordable way to keep your Manassas, VA, home or additional living space cool and comfortable. Unfortunately, issues can arise with your system as it ages or with neglect, resulting in abnormal noises. Here are various possible ductless AC noises and their causes that our professionals can help you address:

Whistling or Hissing Sounds

You may hear a whistling or hissing sound from your ductless air conditioner if there’s a refrigerant leak. This can lead to compressor damage, so scheduling repairs as soon as possible is important.

Clicking or Tapping Noises

Loose components or parts in your ductless air conditioner can cause these noises. Parts may loosen over time or not be tight from an incorrect installation process. You may also have debris in your ductless air conditioner that’s moving around during operation.

Loud Banging During Operation

Your ductless AC system should normally run whisper-quiet. If you notice loud banging or clanging sounds when your ductless AC system is running, turn it off immediately. There’s likely damage to an interior component, and continuing to run it could cause further damage.

Buzzing Noise or Humming

While a loose component can cause buzzing or humming sounds, there could also be an electrical malfunction. Damage to wiring is something a professional should address immediately.

Rattling Ductless AC Noises

A loose exterior panel on your ductless air conditioner can lead to rattling. If you can hear rattling coming from further inside the system, there may be loose connections causing the sound. In either case, it’s best to have our service technicians address this problem to avoid further damage.
