Heat Pump Repair in Southern Maine — Fast, All-Brand Service
When your heat pump or mini-split stops heating or cooling, Southern Maine Mechanical gets it back online fast. Our technicians repair every major brand — Mitsubishi Electric, Bosch, Samsung, Daikin, Fujitsu, and more — across greater Portland and southern Maine, with honest diagnostics and upfront pricing.
Same-Day Heat Pump & Mini-Split Repair
A heat pump that quits in a cold snap or a heat wave can't wait. We dispatch quickly across Portland, South Portland, Scarborough, Gorham, Westbrook, Falmouth, Windham, Saco, Biddeford, and surrounding towns, and our trucks are stocked for the most common failures so we can often repair in a single visit.
We Repair Every Major Heat Pump Brand
Mini-split and ducted heat pump repair is a specialty for us, not an afterthought. We work on Mitsubishi Electric, Bosch, Samsung, Daikin, Fujitsu, LG, Carrier, and most other brands — regardless of who installed the system. We diagnose the root cause rather than just clearing a fault code.
Common Heat Pump Problems We Fix
The most frequent heat pump repairs we handle include: unit not heating or not cooling, frozen or iced-over outdoor coil, refrigerant leaks and low charge, failed capacitors and contactors, faulty reversing valves, communication and sensor faults, dirty filters or coils causing shutdowns, and outdoor units that won't start. We find the real problem and fix it right.
Honest Repair-or-Replace Guidance
If your system is older or the repair is costly relative to its value, we'll lay out the numbers honestly — repair cost versus a new, more efficient system that may qualify for Efficiency Maine rebates. We never push a replacement you don't need.
