HVAC tune-up 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.
