Is Your Ductless AC System in Rockledge, FL, Crying for Help?

An efficient ductless air conditioner produces a soft humming sound as it runs. Therefore, if your mini-split in Rockledge, FL, emits loud sounds, there’s a high likelihood that it’s faulty. Let’s go over some ductless AC system noises you may encounter and what they mean.

Banging

Your ductless AC system’s components may wear out over time and become loose. As your mini-split runs, those components bounce around, colliding with other parts.

The collision makes the banging noise. These loose components can damage other components; hence, it’s vital to schedule mini-split repair services immediately after you hear the sound.

Rattling

Similarly, loose cover panels can cause a rattling noise. This noise may also occur when foreign items, such as sticks and debris, make their way into the outdoor component.

Hissing

Your ductless AC system uses refrigerant to draw heat from your indoor air, thus cooling your indoor air, at the evaporator coil, which is in the indoor part of the system. The fluid then flows to the outdoor part of the system via refrigerant lines, where it releases the heat to the outdoor surroundings.

If there are punctures in the refrigerant lines, the fluid escapes through them. Since the holes are most likely tiny and the refrigerant is at a high pressure, a hissing or whistling noise occurs.

Bubbling

A bubbling noise may suggest that your refrigerant lines have damaged sections. The noise occurs when air bubbles enter the refrigerant lines through these sections.

Grinding

The moving parts of your ductless AC system, such as fan blades, can run out of lubrication. As poorly lubricated components continue working, you may hear a grinding noise. Schedule maintenance services to keep these parts well-lubricated.

Never turn a deaf ear to weird sounds from your ductless AC system. Call the ductless air conditioning experts at Riverside Cooling Inc. immediately after you hear these noises to have the system inspected. Our highly skilled team will find all the problematic parts and repair them.
