Is your ductless air conditioner acting crazy? Call a West Columbia HVAC doctor stat. In many cases, a timely repair can protect your unit from serious damage and keep repair costs low. Here are some things to watch out for:

Unresponsive Ductless Air Conditioner Controls

If a mini-split AC fails to respond when you try to turn it on or off or use the controls, there’s probably an electrical issue or the reversing valve may need replacement.

Unusually High South Carolina Electric Bills

The average lifespan of a ductless AC is 12 to 15 years. HVAC systems lose efficiency with age. In a younger unit, high energy consumption could signal anything from grungy equipment or a clogged air filter to short-cycling or failing parts. Call an HVAC professional when you notice a dramatic change in the cost of your utility bills.

Reduction in Mini-Split AC Cooling Output

A lack of cool air can indicate a refrigerant leak. Once all the refrigerant has drained out of the system, the air handler will simply operate as a fan and nothing more. Refrigerant tends to leak out slowly over time, and the upshot is a gradual decrease in cooling capacity.

Grinding Noise Coming from an Indoor Unit

Grinding noises usually mean that the oiled bearings used to reduce motor friction have worn down. Ignoring the noise could result in the air handler motor overheating and burning out.

Ice Formation on Your Outdoor Unit’s Cooling Coils

Reduced air flow can cause the evaporator coils to freeze over. This could be due to a clogged air filter, a malfunctioning thermostat, a broken fan, a refrigerant leak or a dirty coil. If ignored, the weight of the ice can warp the cooling coil and require a complete coil replacement.
