Aces Highlands installs cold-climate heat pumps designed for Maine winters. As certified GE and Hitachi installers, we handle everything from system selection and sizing to professional installation and testing — and we work with all major brands to fit your budget.
We are certified installers for GE and Hitachi cold-climate heat pumps rated to perform in sub-zero temperatures, and we also work with other major brands to find the right fit for your home and budget. Every installation starts with a proper load calculation to ensure your system is sized correctly — not too big, not too small.

Whether you are adding a single-zone mini-split to a problem room or installing a multi-zone ductless mini-split system for whole-home comfort, we communicate clearly about what to expect and deliver on time. We offer financing options to make your installation more affordable.

Gorham Homes and What They Need
Gorham covers about 51 square miles west of Westbrook and is still largely rural, and its housing has grown in waves. Census estimates put the median home at 1988: about 14 percent of units were built before 1940, largely in Gorham Village and the old farm roads, while roughly a third were built since 2000 as the town became a Portland bedroom community. About 80 percent of homes are single detached houses and about 81 percent are owner-occupied, and about 5 percent are mobile homes. Newer subdivisions are spread well beyond the village, out toward Little Falls, White Rock and North Gorham. Old farmhouses can have stone foundations, add-on wiring and no ductwork, while newer colonials usually have forced air, which is why replacing an old farmhouse boiler and a subdivision furnace swap are very different jobs.
Heating and Cooling in Gorham
Gorham depends on heating oil more than any of its neighbors. Census estimates show about 60 percent of occupied homes on fuel oil or kerosene, about 14 percent on bottled propane, about 12 percent on utility gas and about 8 percent on electricity with wood at nearly 4 percent. Natural gas in Gorham comes from Maine Natural Gas rather than Unitil, and its lines reach only part of town. Sitting inland, away from the ocean's moderating effect, Gorham tends to run colder on clear winter nights than the Portland Jetport, which matters when sizing any system. That combination - high oil use, colder nights and few ducts in older homes - is why cold-climate heat pumps are often paired with an existing boiler here rather than replacing it outright.

Getting to Know Gorham
Gorham began as "Narragansett No. 7" — one of seven townships Massachusetts granted in 1728 to veterans of the Narragansett War and their heirs — and was incorporated under its current name in 1764. On the Gorham–Windham line, Babb's Bridge spans the Presumpscot River as Maine's oldest covered bridge, originally built in 1840 and faithfully rebuilt with locally milled lumber after a 1973 fire.
Gorham today mixes centuries-old farmhouses with newer subdivisions around the village and the USM campus — two very different kinds of heating and electrical work, and we are comfortable in both.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Gorham gets treated. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. Earning the next call, not hitting a sales target, is the entire business plan.
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
Homeowner Guide
What Actually Happens on Heat Pump Installation Day
A heat pump installation looks simple from the outside — an outdoor unit, an indoor head, a line set between them — but the quality of a handful of unglamorous steps is what determines whether the system performs for fifteen years or struggles from day one.

Codes & Permits for Heat Pump Installation in Gorham
In Gorham, plumbing permits come from the town's Local Plumbing Inspector. With 18,336 residents, Gorham is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Fuel oil/kerosene is by far the dominant home heating fuel at 60.4% of occupied units — the highest oil-reliance of the three towns researched — indicating strong oil-to-gas/heat-pump conversion potential.
- 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
- 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
How Aces Highlands Handles Heat Pump Installation in Gorham
- 60% of Gorham households still heat primarily with heating oil, so we size a heat pump installation around whatever is already running the house and tell you straight whether it is worth keeping as a cold-snap backup.
- The circuit feeding the outdoor unit is permitted first, and all refrigerant handling follows EPA Section 608 rules — no shortcuts on either.
- Because Efficiency Maine ties its rebates to Residential Registered Vendor status, we go over what your project actually qualifies for before you commit a dollar.

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.

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.

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.
Heat Pump Installation FAQs
What temperature do cold-climate heat pumps work down to?
The cold-climate systems we install are rated to produce heat at -13°F and below, and continue operating past that with reduced output. Properly sized, they handle the large majority of Maine winter hours on their own; many homeowners keep an existing boiler or furnace as backup for extreme cold.
How long does a heat pump installation take?
A single-zone ductless installation is typically done in one day. Multi-zone systems usually take two to three days depending on the number of indoor heads and any electrical upgrades required.
Are there rebates for heat pumps in Maine?
Yes. Efficiency Maine offers rebates on qualifying cold-climate heat pump installations, and federal energy tax credits may also apply. Aces Highlands helps you identify what your installation qualifies for and provides the documentation you need to claim it.
What size heat pump does my home need?
It depends on your home’s heat loss, not just square footage. We perform a load calculation that accounts for insulation, windows, air sealing, and layout before recommending equipment. Oversized systems short-cycle and dehumidify poorly; undersized systems fall behind in deep cold. Sizing is the most important decision of the whole project.
How long do heat pumps last?
A quality cold-climate heat pump that receives annual maintenance typically lasts 15 years or more in Maine. Keeping coils clean and the outdoor unit clear of snow and debris is the biggest factor in reaching the high end of that range.
