Heat pump not cooling in Summerville: Problems We Fix

Coastal humidity and salt air are hard on air conditioners in Summerville. Condenser coils corrode faster, drain lines clog with algae, and systems run long hours pulling moisture out of the house. Our technicians clean coils, treat drains and check refrigerant charge on every visit because those are the failures we see most here.

Heat Pump Repair in Summerville: Questions We Hear

Why is my heat pump covered in ice?

Some frost is normal. A solid block of ice means a defrost problem, low refrigerant or a failed fan motor.

Why is my electric bill so high in winter?

If the heat pump is running on auxiliary heat strips instead of the compressor, bills double. We fix the cause in Summerville.

How long do heat pumps last?

12 to 15 years with twice-yearly maintenance.
