Heat pump service in Dorchester: Problems We Fix

Coastal humidity and salt air are hard on air conditioners in Dorchester. 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 Dorchester: 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 Dorchester.

How long do heat pumps last?

12 to 15 years with twice-yearly maintenance.

Do you offer heat pump service near downtown Dorchester?

Yes. We cover downtown Dorchester and every part of Dorchester, plus Ridgeville, Harleyville, Saint George. Call (855) 459-5498 for the next available window.
