In comparison to what one of its traditional counterparts would generate, your ductless air conditioner should produce very little noise. So, you need to treat any loud sounds coming from your ductless AC system in Doctor Phillips, FL, as clear signs that something is wrong. Read on to find out more about why your ductless AC system is so noisy.
Hissing or Whistling
In most cases, these noises arise when your mini-split has a refrigerant leak. Age, corrosion, and damage may all contribute to damaging your system’s refrigerant lines and creating holes in them. When refrigerant escapes through these holes, the resulting friction may produce a hiss or a high-pitched whistle.
Alternatively, your system may start emitting whistling noises because of cracked valves, clogged air filters, a faulty compressor or excessively high interior air pressure. Though you can replace your filters on your own, it’s best to leave the other problems to the care of professionals.
Noisy Ductless AC Is Rattling
When you hear something rattling, you should suspect that either a part has come loose somewhere or debris is bouncing around inside. Loose parts might be things like bolts and fan blades, and debris might include twigs or pebbles. Regardless, you need to schedule maintenance.
Cracking or Popping
Unlike most other noises that you might hear coming from your mini-split, these are generally harmless. They’re among the natural results of your system’s ordinary operations.
As your system starts to work and produce cool air, the plastic in its air handler may slightly contract. As the system turns off and warms up, that plastic may expand again. As long as the cracking and popping noises that result from this are temporary, you’ll have nothing to worry about.
