Ductless mini-splits are a great HVAC choice for many homeowners due to their numerous advantages. However, to keep them running in optimal condition, it’s important that you check your system regularly. Read on to learn about four signs that indicate your ductless unit in Newberry, SC, is in need of repair.

1. Unusual Sounds

Pay attention to any hissing noise from your ductless system. It may mean that the greased bearings attached to reduce friction need replacement. Also, the whole unit might produce a small banging noise.

These noises are signs that your system needs repair or replacement. Failure to attend to these issues may result in a breakdown of the whole system. You should call an HVAC technician when you hear unfamiliar noises from your unit.

2. High Energy Bills

Unusually high energy bills can suggest that your ductless mini-split is inefficient and needs repair. A ductless system loses efficiency after about 10 years, and this can result in an increased energy bill. Annual maintenance can give you a clue as to how your system is faring as it ages, extend its lifespan and give you plenty of warning when you need to start budgeting for a replacement.

3. Unresponsiveness

The AC or heat should respond properly after you change the remote or thermostat batteries. If this isn’t the case, then there could be a problem with the unit. You can try switching it off and on manually, and if there is no response, then you need to call for a repair service visit.

4. Ice Forming on the Cooling Coils

The unit’s evaporator coil can freeze over as a result of reduced airflow. A dirty coil, broken fan or clogged air filters could cause this issue. You shouldn’t ignore this problem because the ice could impact the cooling coil.
