Should My Ductless Mini-Split Make Noise in Crawfordville, FL?

Your ductless air conditioner is a quiet machine that provides cooling for your Crawfordville, FL home. Though some subtle sounds are common from this system, loud and unusual noises often indicate the need for repairs. Read on and learn about a few of the common noises your ductless mini-split system might make that should trigger the alarm for professional repair services.

Loud Banging and Clanging

Loud bangs and clangs can give you a startling feeling for good reason. These sounds often indicate that a part inside the ductless AC is loose or damaged. The banging and clanging happen as the part moves around during the cooling cycle.

Rattling and Vibration

Rattling and vibrating noises may mean that debris has found its way into your ductless system. The debris rattles around as the system cycles, creating excess noise. Our service techs check for debris and contaminants during annual maintenance to lower the risk of these sounds during summer cooling.

Hissing and Bubbling

Air inside the refrigerant lines can create a hissing or bubbling noise. When air gets into the refrigerant lines, you likely have a leak somewhere. Call us immediately if you hear hissing and bubbling so that we can find and fix the refrigerant leak.

Grinding

Dry or damaged bearings inside your ductless mini-split system can cause a loud grinding noise similar to metal scraping against metal. These bearings require lubrication to protect against wear and tear. Our technicians can lubricate the bearings and replace them if they have extensive damage.

Now that you know the difference between normal operating sounds and troubling noises, you have a better idea of when to call for repairs. If you need ductless mini-split repairs in your Crawfordville, FL home due to unusual or loud noises, call our service techs at Advanced Air Care, Heating & Cooling today.
