Heat Pump Installation for Eliot Homeowners

Aces Highlands handles heat pump installation for homeowners throughout Eliot. We work out of 508 Riverside St Unit 1 in Portland, a short drive into York County, so response times stay quick and every job benefits from knowing the local housing stock and code requirements.
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.

Eliot Homes and What They Need
Eliot's median home was built in 1979, with about a quarter of housing predating 1940, reflecting a town that grew substantially from roughly 2,500 residents in 1950 to over 6,700 by 2020. That range of construction eras means service calls here run from vintage farmhouse wiring to routine work on newer subdivisions.
Heating and Cooling in Eliot
About 62 percent of Eliot households heat mainly with fuel oil, with bottled or tank propane at 21 percent and electricity at 7 percent; there is no confirmed natural gas utility reaching Eliot itself, even though neighboring Kittery has gas service. A heat pump paired with the existing oil system is a common upgrade here.

Getting to Know Eliot
Eliot incorporated as its own town on March 1, 1810, and today borders three New Hampshire communities -- Dover, Portsmouth and Newington -- across the Piscataqua River, along with South Berwick and York on the Maine side. The town is also home to Green Acre, a historic Bahá'í school property.
Eliot's population has grown steadily from around 1,650 residents in 1810 to over 6,700 by 2020, with most of that growth landing in the second half of the 20th century. The town is now extending municipal water and sewer service along the Route 236 corridor under a tax-increment financing district.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Eliot gets treated. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. 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 Eliot
In Eliot, plumbing permits come from the Local Plumbing Inspector at the Eliot Code Enforcement Office (Shelly Bishop, Code Enforcement Officer / Health Officer) (1333 State Road, Eliot, ME 03903, 207-439-1813 Ext. 110). With 7,146 residents, Eliot is required to enforce the Maine Uniform Building and Energy Code (MUBEC).

- 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 Installation in Eliot
- 62% of Eliot 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.
- We flag which Efficiency Maine incentives apply to a heat pump installation before work starts, since the rebate only applies through a Residential Registered Vendor.

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.

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.
