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.

Gray Homes and What They Need
Gray's roughly 4,600 homes are younger than much of Cumberland County. Census estimates put the median year built at 1983, and only about one in eight predates 1940. Those older houses cluster around Gray Village and along the old roads out toward Dry Mills. The bigger story is the building wave of the 1970s through the 2000s, when capes, ranches and colonials went up on wooded lots within reach of Turnpike exit 63; about a quarter of homes date from 2000 or later. Roughly one in twenty is a manufactured home, and around 670 units are held for seasonal use, many of them camps on Little Sebago, Crystal and Forest lakes. Houses from the 1980s and 1990s are now reaching the age where original boilers, furnaces and electrical panels with no spare breaker space come due, while a lakeside camp raises questions about insulation and year-round use.
Heating and Cooling in Gray
Heating oil still dominates in Gray. Census estimates show about six in ten occupied homes heat mainly with fuel oil or kerosene, roughly 18 percent with propane, 12 percent with electricity and nearly 8 percent with wood, while utility gas barely registers at under 1 percent. Natural gas mains effectively do not reach the town, so propane is the fallback wherever a gas range or boiler is wanted. Gray is inland and snowy: its climate record shows January averaging in the low 20s Fahrenheit and around 84 inches of snow a year, and the National Weather Service office that forecasts for western Maine and New Hampshire sits on Weather Lane in Gray. For an oil-heated house, a cold-climate heat pump installation can carry most of the winter load while the existing boiler or furnace stays as backup for the coldest nights, and the same equipment handles summer cooling.

Getting to Know Gray
Gray holds one of Maine's most unusual Civil War stories: in 1862, the body of an unknown Confederate soldier was mistakenly shipped to Gray instead of a fallen local Union lieutenant. The women of the town buried the stranger in Gray Village Cemetery and paid for his headstone — marked simply "The Stranger" — and the grave is still tended today. Gray is also home to the Maine Wildlife Park, the state's refuge for animals that cannot return to the wild.
From the village center out to Dry Mills, Gray's homes range from 1800s farmhouses to newer builds off Route 26 — and we service heating, plumbing, and electrical in all of them.
Local & Independent — Not a Franchise
We are an independent, Portland-based company, not a franchise chain routing your Gray job to a call center. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
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 Gray
In Gray, plumbing permits come from the Local Plumbing Inspector at the Gray Code Enforcement Office (Henry Pennell Municipal Complex, 24 Main Street, Gray, ME 04039, (207) 657-3339). With 8,269 residents, Gray is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The Gray Water District, established in 1929, draws from a groundwater aquifer and serves roughly 1,100 connections; most of the rest of town relies on private wells.
- 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 Gray
- 53% of Gray households still heat primarily with heating oil, so we size a heat pump repair around whatever is already running the house and tell you straight whether it is worth keeping as a cold-snap backup.
- 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.
- Efficiency Maine rebates only pay out when a Residential Registered Vendor did the install, so we confirm eligibility with you up front — you can check any installer's registration yourself before signing anything.
Hancock Street near the center of Gray village, close to the town's public library.

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.
