Most repair calls in Portland and Gorham start the same way: the house is cold, the outdoor unit is iced, or a head is blinking a code. We work on Mitsubishi, Daikin, and Samsung systems every week, plus most other ductless and ducted heat pumps.
Common jobs include failed outdoor fans, clogged condensate drains, dirty coils that trip high pressure, sensors out of range, and boards stuck in defrost. We also recover refrigerant when a line is leaking and test both heat and cool before we leave.
If the unit is near the end of its life we will say so. Our replacement team can price a new system with Efficiency Maine rebates instead of stacking repairs. After a fix, annual cleaning keeps the same fault from coming back next season. Many of these calls sit next to a ductless mini-split we or another shop installed in Portland, Westbrook, or South Portland.

We do not guess. Error codes, coil temperature, and refrigerant readings tell us whether you need a capacitor, a fan motor, a board, or a recovery and leak search.
You see the price before any part goes in. If a repair is a poor spend next to a rebate-eligible replacement, we say that too.
Typically $150–$600
Diagnostic visits and common repairs (fans, sensors, drain lines, capacitors) usually land in this range. Compressors, boards, and refrigerant work cost more. You get a written price before we start.

Answers to the questions Southern Maine homeowners ask us most.
Iced coils, a dirty filter, a failed outdoor fan, low refrigerant, or a board in defrost lock can all cut heat on a Maine night. We read the error code, check charge, and test both modes so you know whether it is a clean-and-reset or a part.
Yes. Those are the brands we install every week, and we also service most other ductless and ducted heat pumps — including systems another company put in. Bring the model number if you have it; we can usually diagnose without it.

Typical service calls and common repairs land between $150 and $600. Compressors, control boards, and refrigerant work cost more. You get a written price before we order parts or open the system.
If the unit is under ten years old and one part failed, a repair is usually the right call. If it needs frequent visits, uses a phased-out refrigerant, or cannot keep up below zero, we will show replacement options and Efficiency Maine rebates instead of stacking bills.
Yes. A large share of our service calls are on equipment another contractor installed. We inspect it, tell you what failed, and service it if the repair is sound.

“The technician arrived right on time, diagnosed the issue quickly, and had both of my heat pumps running smoothly in no time. They explained everything clearly and didn’t try to upsell unnecessary services — just honest, quality work. The price was fair, and the customer service was exceptional.”

“I was being serviced by another local company as I had a crack in my Daikin Drip Pan. The previous company came out 3 times and finally diagnosed it. They ordered the part and then never showed up again even though the part was under warranty. I found Southern Maine on a google search and gave them a call. Sam called my back immediately.”

“I had neglected annual service out of fear that it would cost a fortune but when I called to make the appointment, they let me know what was included in service and the cost- amazing! I appreciated that they were willing to service the system even though they did not do the installation.”

“I contacted Southern Maine Heat Pumps to service my two units. The technicians who came out to service our heat pumps did an outstanding job. They were very thorough and helpful. They did a way better job than what I have experienced before with other maintenance services.”
