Gelinas HVAC: Your Source for Plumbing, HVAC, and Electrical Services

When a heat pump struggles during a cold snap, electric auxiliary heat strips engage to maintain indoor temperatures, causing electric bills to surge. Gelinas HVAC Services has repaired ducted and ductless heat pumps across Scarborough since 1994, specializing in cold-climate models. Operating under Maine Electrical License #MS60022397, our technicians inspect refrigerant charges, reversing valves, and defrost controls to restore efficient performance aligned with DOE heat pump guidelines. Members save on repair service through our Home Advantage Membership. Call (207) 672-2801 to speak with a representative about scheduling a diagnostic visit.

We are a local, family-owned team with extensive experience in cold-climate heat pumps, keeping Scarborough homes warm through the harshest winter weather.

Is it normal for a heat pump outdoor coil to ice up in winter? Light frost is normal and clears during defrost cycles. Heavy, solid ice accumulation indicates defrost control faults or low refrigerant.

Why is my heat pump running constantly without reaching temperature? Continuous running with poor heat output typically points to refrigerant leaks, dirty outdoor coils, or defrost failures.

What causes a heat pump to get stuck in cooling or heating mode? Mode locking usually stems from a failing reversing valve or control circuit malfunction.

Do you service both ducted and ductless heat pumps in Scarborough, ME? Yes, we repair all ducted central heat pumps and ductless mini-split systems.

Should I turn off my heat pump if it is heavily encased in ice? Yes, turn off the system to prevent fan blade and coil damage, then call us for immediate service.

Are emergency heat pump repairs prioritized during winter freeze events? Yes, if a heat pump serves as your primary heating source, emergency no-heat dispatch is prioritized.

Cold-climate heat pumps work hard year-round, making prompt repairs essential when defrost cycles or reversing valves experience issues. Scheduling twice-yearly heat pump maintenance optimizes seasonal performance and prevents unexpected heating or cooling losses. For wall-mounted ductless systems, visit our dedicated mini split repair page, or explore central system support under HVAC repair. If your current system is undersized or struggling in sub-zero weather, our heat pump installation team evaluates high-efficiency replacements, while our electricians install panel-level surge protection to shield sensitive inverter boards.

Heat pump problems tend to worsen, so keep an eye out for these key warning signs:

Heating or cooling output feels significantly weaker than it did last year.
Ice builds up on the outdoor coil and fails to clear during automatic defrost cycles.
The system short cycles repeatedly or gets stuck in a single operating mode.
You hear unusual grinding, buzzing, or hissing sounds coming from the outdoor unit.
Electric auxiliary backup heat runs far more often than it should.

That last point is easy to miss because backup electric heat keeps the house warm while quietly doubling or tripling your bill. Call (207) 672-2801 to book your free estimate and to solidify your path to a fix.

Don’t let a failing heating or cooling system disrupt your home’s comfort and safety. Whether you need fast emergency dispatch or routine support, Gelinas HVAC Services delivers prompt, reliable heat pump repair across Scarborough and Greater Portland.

Common Heat Pump Problems We Fix

Cold-climate heat pumps provide year-round heating and cooling, but their continuous year-round operation causes mechanical wear over time. When heat pumps stop heating during Maine winters or fail to cool in summer, our Scarborough service techs quickly isolate the root cause. Here are the heat pump issues we resolve most in the field.

The reversing valve is the core component that shifts your heat pump between heating and cooling modes. When its internal solenoid coil fails or the valve body sticks, the unit remains stuck in cooling mode during winter or heating during summer. We test solenoid coil continuity, check system pressures, and replace stuck reversing valves using precision brazing techniques.

During cold, damp winter days, frost naturally forms on the outdoor coil. If the defrost control board or outdoor temperature sensor fails, the coil turns into a solid block of ice and blocks all heat absorption. We test defrost sensors, manually force defrost cycles, clear ice buildup, and replace faulty defrost logic boards.

When outdoor temperatures plummet, heat pumps rely on electric auxiliary heat strips to supplement warmth. If heating element sequencers or thermal cutoffs fail, your system struggles to keep up on sub-zero nights. We test heat strip resistance, replace burnt heating elements, and verify stage control relays so back-up heat kicks on reliably.
