Aside from the occasional whirring or clicking sounds, ductless systems are famously quiet and efficient. If your ductless HVAC system in Hanover, PA starts making strange noises, there are several different issues that might be causing them.
1. Hissing
Ductless mini split systems contain refrigerant, which is a fluid that transfers heat between your house and the outdoors. If this substance leaks, your refrigerant line will likely produce a hissing sound. You should call a ductless system expert to repair the leak before it causes more damage.
2. Buzzing
Broken fan blades, fan motors, and compressors can produce buzzing sounds, but this noise often results from electrical issues. Your ductless mini-split system could draw too much power and increase your energy bills. When you don’t treat it, the unit could overheat.
3. Grinding
The bearings inside your ductless mini-split system reduce friction. However, these bearings can eventually wear down, causing friction that produces grinding noises. The friction will only worsen, so act quickly when you hear grinding sounds.
4. Rattling
Rattling sounds indicate that your unit has debris or loose components inside the compartment. Over time, small parts gradually loosen and slide out of place. Fortunately, our HVAC experts can tighten these parts during maintenance visits.
5. Short Cycling
If you hear your ductless system turning on and off too frequently, you might have a refrigerant leak, clogged air filter, broken compressor or faulty thermostat. Whatever the case, short cycling drains energy and reduces your mini-split system’s lifespan, so call an expert before your energy bills go up.
