Why Does My Ductless AC System Make So Much Noise?

Those who operate a ductless air conditioner to cool their living spaces know how quietly they operate. If your mini-split makes strange noises in your Clearwater, FL, home, you have an immediate cause for concern. Here are a few reasons your ductless AC system might make a loud noise:

Rattling

Even though your mini-split has no ducts, the risk still exists that various kinds of debris may accidentally get into the system and create a mess. Dirt, twigs, acorns, pebbles, bits of grass, and similar waste can fly into your mini-split and begin rattling around.

These foreign objects are more than merely annoying. Depending on where they land and how long they remain in your ductless AC system, they may also cause meaningful damage. The best way to remove them is to ask an HVAC service technician to perform routine maintenance on your system, which you should do at least once per year.

Hissing

This noise is a sign that your mini-split is leaking refrigerant. When you notice this is happening, we recommend exiting your home and calling for help from one of our HVAC service technicians. Bubbling and gurgling noises are further confirmation of a leak. These are the sounds that typically emerge when air bubbles displace refrigerant.

Inhaling refrigerant can produce vomiting, nausea, neurological damage and even worse symptoms. Once you are aware of these noises, seek help from a professional immediately.

Grinding

Grinding noises are a sign that there is friction going on between some of your mini-split’s parts, which may be the inadequate lubrication of those parts or some kind of mechanical failure. The parts in question might include the fan motor, blower wheel, motor bearings or compressor.
