Heat Pump Installation for Kennebunk Homeowners

For heat pump installation in Kennebunk, homeowners turn to Aces Highlands: a Portland-based crew (508 Riverside St Unit 1) that is minutes from York County and already familiar with the homes, climate and codes here.
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. Most heat pump installations also require an electrical panel upgrade — we handle that as part of the project.
Our installations include indoor and outdoor unit placement, refrigerant line routing, electrical connections, and thorough system testing. We take pride in clean line sets, secure mounting, and a tidy work area when we leave.
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.

Kennebunk Homes and What They Need
Kennebunk has the newest median home of the five York County coastal towns Aces studied, built in 1983, with under 19 percent of units predating 1940 and about 30 percent predating 1960. That newer stock still runs plenty of aging original heating and electrical systems worth a checkup.
Heating and Cooling in Kennebunk
About 56 percent of Kennebunk households heat mainly with fuel oil, with bottled or tank propane at 18 percent and electricity at 15 percent; Unitil also supplies natural gas to parts of town. Where gas is available, a gas boiler installation is often the simplest upgrade from an old oil system.

Getting to Know Kennebunk
Kennebunk broke off from Wells and Arundel to incorporate as its own town on June 24, 1820; the name comes from an Abenaki word describing 'the long cut bank.' Its Summer Street Historic District, home to the Federal-style Wedding Cake House, was the very first historic district in Maine listed on the National Register of Historic Places.
Kennebunk is also the hometown of U.S. Senator and Secretary of State Edmund Muskie and headquarters to Tom's of Maine. Since December 1893, part of town has been served by the Kennebunk Light & Power District, one of only two municipally owned Light & Power Districts left in the state.
Local & Independent — Not a Franchise
Aces Highlands answers to Kennebunk homeowners directly, not a franchise office somewhere else in the country. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. 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
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 Kennebunk
In Kennebunk, plumbing permits come from the Local Plumbing Inspector at the Kennebunk Code Enforcement Office (Community Development Department) (Kennebunk Town Hall, 2nd Floor, 1 Summer Street, Kennebunk, ME 04043, (207) 985-2102 ext. 1303). With 11,820 residents, Kennebunk is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Kennebunk's Summer Street Historic District was the first historic district in Maine listed on the National Register of Historic Places, which can add review requirements for exterior work in that area.
- 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
- 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
How Aces Highlands Handles Heat Pump Installation in Kennebunk
- 56% of Kennebunk 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.
- 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.
- 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.

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.

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!

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!

Where to begin? These guys hooked up a sauna for me and did an amazing job, it was not a small job. Projects big or small, these guys are my go to. Responsive, reasonably priced, and professional. In a world where it is tough to get good service, I'm thrilled to have these guys in my phone.
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.
