Heat Pump Installation for Lewiston Homeowners
Cold-Climate Rated Systems
Proper Load Calculations
Clean, Professional Install
When Lewiston homeowners need heat pump installation, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Lewiston in Androscoggin County — so we respond quickly and know the homes, the weather, and the codes in your area.
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.

Lewiston Homes and What They Need
Lewiston's median home was built in 1957, with about 32 percent of the housing stock dating before 1940 and 54 percent before 1960 -- a mill-city profile concentrated in the tenement and triple-decker neighborhoods that grew up around the Bates Mill complex in the late 1800s and early 1900s. That density and age combination means plumbing work in older Lewiston buildings often has to account for shared walls and stacked units, not just a single-family layout.
Heating and Cooling in Lewiston
About 53 percent of Lewiston households heat mainly with fuel oil, 23 percent with utility gas, and 10 percent with electricity, per Census estimates, though Lewiston is not in Summit Natural Gas of Maine's published service area, so that utility-gas share likely reflects an older, more limited local distribution system rather than a modern buildout. Either way, a lot of Lewiston's oil-heated multi-unit buildings are strong candidates for a heat pump retrofit.
Getting to Know Lewiston
Lewiston grew up around Lewiston Falls on the Androscoggin River, which started powering the Bates Manufacturing Company's mill complex in 1852. For roughly three decades, Bates was Maine's single largest employer, and it stayed one of Lewiston's biggest employers well into the 20th century, a scale of industry that shaped the city's dense, mill-town neighborhoods.
The Androscoggin River still forms Lewiston's western border, separating it from twin city Auburn, and the two towns share more than a river: Lewiston draws its water through the jointly run Auburn Water District. That kind of shared infrastructure is common between the two cities, a legacy of how closely their industrial histories are tied together.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Lewiston under its own name. 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 Lewiston
In Lewiston, plumbing permits come from the Local Plumbing Inspector at the Planning & Code Enforcement, City of Lewiston (27 Pine Street, Lewiston, ME 04240, 207-513-3000). With 37,121 residents, Lewiston is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Lewiston sits on the east bank of the Androscoggin River at Lewiston Falls (Great Falls), the water power that drew the Bates Manufacturing Company and four other mills starting in 1852; Bates Mill was Maine's largest employer for three decades.
- 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 Lewiston
- Because roughly 53% of Lewiston homes are already on heating oil, a heat pump installation usually means deciding how much of the heating load the new equipment should carry, not ripping out what's there.
- Every outdoor unit we set gets its own permitted circuit before it's wired in, and any refrigerant work is done under our EPA Section 608 certification.
- 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.

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!

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.
