If you have a ductless HVAC system in your Aiken, GA home you should already know it’s very quiet when operating correctly. So it’s easy to get concerned when your ductless starts making unfamiliar noises. Here are the causes of three common sounds ductless HVAC systems sometimes make.
1. Rattling Sounds
If you hear a rattling sound from your mini-split, it typically means one of two things. One is that a foreign object has gotten into your outdoor unit. It can happen as the wind blows debris around outside or a twig falls into the fan.
The other possibility is that a component inside your ductless system has come loose. That can happen in your outdoor unit or indoor air handlers. If you can’t identify the source of the problem, you might need a ductless HVAC repair.
2. Hissing Sounds
If you hear hissing from any part of your ductless HVAC, it likely signals trouble. Most often, hissing means there’s air inside your refrigerant lines. That can only happen if those lines have a leak.
Refrigerant leaks will sap your system’s efficiency and capacity to produce cool air. It also unnecessarily strains your system’s compressor. You should make a repair appointment for an HVAC professional to find and fix the leak as soon as you hear a hissing sound.
3. Buzzing Noises
Finally, it’s not unusual to hear buzzing noises from your mini-split when it malfunctions. It indicates that there’s an electrical issue in your system. Sometimes, the problem is something as simple as a loose electrical wire.
Occasionally, buzzing can mean a capacitor failure. Your mini-split relies on capacitors as part of its fan-starting mechanisms. Fortunately, replacing a failed capacitor is usually easy for an experienced HVAC technician.
