Ductless AC in McMurray, PA

What Are Those Noises Coming from Your Ductless AC in McMurray, PA?

May 19, 2021

Ductless systems are energy efficient and provide a quiet operation. Strange noises coming from your system are an indication that something is wrong. Here are some of the noises that might come from your ductless AC in McMurray, PA.

Rattling Noise

When components are loose inside your indoor or outdoor unit, they may produce a rattling noise. If your condenser is producing this noise, it may be due to debris on the unit. Increased wear and tear due to aging causes parts to become loose inside your system.

Rattling noise is a result of loose parts hitting the exterior framing of your system. A qualified service technician can help you troubleshoot your system and tighten any loose components.

Hissing Sound

When air bubbles form in your refrigerant line, they may produce a bubbling or hissing sound. This usually happens when there is leakage in the refrigerant line. A leak can lead to the breakdown of your HVAC system if it is not fixed by a qualified service technician.

Excess moisture in your ductless AC can also make bubbling sounds. It usually occurs when the drainage line has a crack, hole, or blockage. A professional technician can help you replace your drainage line as the task requires special tools and equipment.

Buzzing Noise

If you hear a buzzing or vibrating noise, your outdoor compressor unit might have a problem with the electrical system. This can lead to energy inefficiencies and high monthly electric bills. A problem like this requires a professional technician to fix it.

Buzzing noise can also be a sign of loose or broken fan blades in your compressor unit. Other issues that can produce this type of sound include dirty condenser coils, faulty fan motor, and loose components. Spring preventive maintenance can help avoid these issues and improve your comfort.
