Heat Pump Repair for Scarborough Homeowners

Scarborough sits in Cumberland County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for heat pump repair gets a technician who already knows the local housing and codes, not a first-timer.
When your heat pump stops working or is not performing like it should, Aces Highlands provides fast, accurate diagnostics and honest repairs. We fix the actual problem — not just the symptoms.
Heat pump issues can range from simple fixes like a dirty filter or tripped breaker to more complex problems like refrigerant leaks, compressor failures, or control board malfunctions. Our technicians diagnose accurately the first time so you get the right repair without paying for unnecessary parts.
We service all major heat pump brands including GE, Hitachi, Mitsubishi, Daikin, Fujitsu, and LG. We carry common replacement parts to complete most repairs in a single visit. Regular heat pump maintenance can help prevent many common repair issues before they start.
If your heat pump is beyond repair or the cost of fixing it does not make sense, we will tell you honestly and help you evaluate replacement options.
Why Scarborough Calls Aces Highlands
- A Cumberland County crew that already knows Scarborough's streets and housing stock
- Pricing you see up front and a diagnosis you can trust — never a sales pitch
- Fast turnaround — we get most jobs booked within days, not weeks
- Licensed, insured, and background-checked, and reviewed by real customers on Google
Scarborough Homes and What They Need
Scarborough is largely a late-20th-century town. Census estimates put the median home at 1988, with only about 8 percent of units built before 1940 and roughly 30 percent built since 2000. About seven in ten homes are single detached houses and more than three quarters are owner-occupied. The older stock clusters in beach villages such as Pine Point, Higgins Beach and Prouts Neck, where cottages built for summer use have often been converted to year-round living, while subdivisions fill the land around Dunstan, Oak Hill and North Scarborough. The newest layer is The Downs, a mixed-use neighborhood rising on the old racetrack site with apartments, condos and single-family homes. Newer houses usually come with ductwork, which makes a ducted heat pump installation straightforward, while converted cottages often need insulation, freeze protection and wiring brought up to date first.
Heating and Cooling in Scarborough
Heating in Scarborough leans on delivered fuels. Census estimates show about 48 percent of occupied homes on fuel oil or kerosene and about 19 percent on bottled propane - a high propane share for a town this close to Portland - with about 15 percent on electricity and about 13 percent on utility gas. Unitil's Northern Utilities serves the town, but gas mains follow the more built-up corridors rather than every road. The town spans a large tidal marsh and several river mouths, so the beach villages feel the ocean's moderating effect while North Scarborough, farther inland, can run colder on clear winter nights. Salt air along Pine Point and Higgins Beach shortens the life of outdoor coils and cabinets. Propane households have a real choice between a high-efficiency gas furnace replacement and a cold-climate heat pump that uses the existing ducts.

Getting to Know Scarborough
Scarborough is one of Maine's oldest towns — incorporated on July 14, 1658 — and it is home to Scarborough Marsh, the largest contiguous saltwater marsh in the state. The town's Prouts Neck peninsula is where the painter Winslow Homer lived and produced many of his famous seascapes.
All that tidal coastline means Scarborough homes deal with real salt-air exposure. It is why we pay close attention to equipment placement and corrosion resistance on every outdoor condenser and heat pump we install near the water.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Scarborough — not a national franchise. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. Getting invited back is the only metric that matters here.
How a Heat Pump Works
- Outdoor unit — fan and compressor extract heat from outside air
- Reversing valve — switches the system between heating and cooling
- Line set — carries hot, high-pressure refrigerant indoors
- Indoor coil — releases heat into the airstream
- Warm air — the blower delivers it to the room

Codes & Permits for Heat Pump Repair in Scarborough
In Scarborough, plumbing permits come from the Local Plumbing Inspector at the Town of Scarborough Planning & Codes Department (Scarborough Municipal Building, Lower Level Room 125, 259 U.S. Route 1, Scarborough, ME 04070 (mailing: PO Box 360, Scarborough, ME 04070-0360), 207-730-4040). With 22,135 residents, Scarborough is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Scarborough has significant Gulf of Maine/Saco Bay coastline, including the Prouts Neck, Pine Point, and Higgins Beach neighborhoods, plus Scarborough Marsh — meaning salt-air exposure and marsh/shoreland conditions are a live factor for coastal work.
- Anyone who connects or disconnects gauges or adds/removes refrigerant on a heat pump or air conditioner must hold EPA Section 608 technician certification; the credential does not expire once earned. epa.gov
- The electrical circuit that feeds a new heat pump or AC condenser needs an electrical permit, issued by the Electricians' Examining Board or the town's own electrical inspector, before the wiring is installed or altered. maine.gov
- Efficiency Maine offers rebates of up to $9,000 on qualifying heat pumps, but the equipment must be installed by an Efficiency Maine Residential Registered Vendor for the homeowner to receive the rebate. efficiencymaine.com
How Aces Highlands Handles Heat Pump Repair in Scarborough
- With heating oil the leading fuel in Scarborough (about 48% of homes), most heat pump repair jobs here are an add-on to an existing system rather than a full replacement — we walk you through both paths.
- We pull the electrical permit for the new circuit before touching the outdoor unit, and refrigerant handling stays inside EPA Section 608 the whole job.
- We flag which Efficiency Maine incentives apply to a heat pump repair before work starts, since the rebate only applies through a Residential Registered Vendor.

Elijah and Highlands Heating & AC were super helpful! Boiler failed over the weekend and Elijah was very responsive and helpful, getting us up and running right away. I would recommend him at HH&AC highly!

We highly recommend Highlands Heating & AC. They are extremely responsive, knowledgeable and do great work. Our boiler stopped working and Elijah was quick to respond after hours on a Friday. He installed a new boiler and heat pump hot water heater.

He was very friendly. He gave me an honest explanation on why I shouldn't recharge my A/C unit and what he suggested made much more sense. He really took care of everything. He is very professional, always called me with updates. 5 stars is not enough — I give this company 10 stars.

I've had three HVAC issues over the past two years. Each time I call, Elija or the office picks up the phone, and my problem is fixed in 24 hrs. Their solutions always feel correct and honest. I cannot recommend them more.

Heat Pump Repair FAQs
Why is my heat pump covered in ice?
Light frost on the outdoor coil is normal — the unit runs periodic defrost cycles to clear it. Solid ice that never clears is not normal, and usually points to a failed defrost sensor or board, low refrigerant, or blocked airflow. Shut the unit off and have it diagnosed before the ice damages the fan or coil.
Why is my heat pump blowing cold air in heat mode?
Check the remote is actually in heat mode and the filters are clean first. If those are fine, the usual causes are low refrigerant from a leak, a failing reversing valve, or a compressor issue — all of which need a technician with gauges to confirm.
How much does heat pump repair cost?
Simple fixes like condensate clogs, sensors, or capacitors are commonly a few hundred dollars. Board replacements and refrigerant leak repairs cost more, and we always quote before we repair, so you can decide with the real number in front of you.
Do you service heat pumps you did not install?
Yes. We repair all major brands — GE, Hitachi, Mitsubishi, Daikin, Fujitsu, LG and others — regardless of who installed the system.
Is it worth repairing a 10-year-old heat pump?
Often yes, if the repair is minor and the system was installed well. Past 12–15 years or facing a compressor or major refrigerant repair, replacement usually makes more financial sense — especially with Efficiency Maine rebates lowering the cost of a new system. We give you both numbers and let you choose.
