Common Mini Split Issues We Resolve

Our experienced professionals at Renhard Heating and Cooling have handled every mini-split issue imaginable. We understand that each problem, no matter how small, can impact your home’s efficiency and comfort.

Unit Fails to Power On

This might be due to a tripped breaker, unplugged power source, or a malfunctioning remote. More advanced issues may include a faulty capacitor, damaged control board, or internal wiring that requires expert attention.

Insufficient Cooling or Heating

When your system runs but doesn’t adjust the temperature, it could be low refrigerant, clogged air filters, or dirty evaporator/condenser coils preventing proper heat exchange.

Water Leaks from Indoor Unit

Leaks often result from a clogged condensate drain line caused by algae or debris. Alternatively, a cracked drain pan might be allowing water to escape into your home.

Strange or Loud Noises

Grinding, squealing, or rattling noises often signal issues like a worn motor bearing, loose parts, or debris buildup. These can lead to significant damage if left unresolved.

Unpleasant Odors

Musty smells usually mean mold or bacteria growth on the evaporator coil or inside the drain pan. A burning smell could indicate an electrical issue or an overheating motor—both need immediate attention.

Ice or Frost Buildup

Coil frost is a clear warning of restricted airflow or low refrigerant. Both conditions hamper performance and increase energy use.

Remote or Thermostat Malfunctions

Sometimes, the controller is the root cause. Dead batteries, signal interference, or a faulty thermostat may require technical troubleshooting.

Repair vs. Replacement: Making the Right Choice

It’s not always easy to decide whether to repair or replace your mini-split system. That’s where we come in. At Renhard Heating and Cooling, our honest technicians guide you through every step.

If your system is under 12 years old and well-maintained, a repair is likely worthwhile. But if it's over 15 years old, frequently breaks down, or needs a major component like a compressor, replacement may be more cost-effective. New models offer higher energy efficiency, improved comfort, and long-term savings.
