It’s a scorching summer afternoon in Goose Creek, SC, and your newly finished sunroom—the pride of your home—is turning into a sauna. You crank the ductless mini-split that usually cools the space in minutes. Instead of relief, you’re greeted by strange noises: a hiss here, a rattle there. Something’s wrong. When a ductless AC system starts making unexpected noises, it’s your mini-split’s way of crying for help. And in South Carolina’s oppressive summer heat, ignoring those sounds could lead to discomfort, expensive repairs or total system failure.
Hissing: A Dangerous Refrigerant Leak
If you hear a steady or intermittent hissing sound, it likely means the system has a refrigerant leak. This is harmful to the environment and severely reduces your mini-split’s cooling power. Goose Creek’s long, hot summers demand reliable air conditioning, so a leak will quickly become noticeable. Shut the system off immediately and call a certified HVAC service technician to locate and seal the leak before permanent damage occurs.
Rattling: Loose Parts or Debris
Rattling often means internal components like screws, brackets or fan blades have come loose. It could also signal debris like leaves or insects caught in the outdoor unit. While this might seem minor, continuing to run the mini-split can lead to costlier damage over time. Turn off the system and call a service technician for a full inspection and tightening of components.
Screeching: Fan or Motor Failure
A high-pitched screech or squeal usually points to a worn-out fan motor or failing bearings. These issues are common when a system is overworked during hot stretches. Ignoring them can lead to full motor burnout. If your ductless AC system starts shrieking, shut it down and schedule a service call before the damage worsens.
Gurgling: Drain Line Backup
If your ductless system sounds like it’s bubbling, the condensate drain line might be clogged. In high humidity, like Goose Creek summers, this can lead to water backing up and damaging your wall or mini-split. A pro can flush the line and ensure proper drainage to protect your room addition.
