Heat Pump Installation for Lisbon Homeowners

Need heat pump installation in Lisbon? Aces Highlands runs out of 508 Riverside St Unit 1 in Portland and covers Androscoggin County routinely, which means a technician who already understands the area's homes and permit process shows up, not a stranger learning it on the job.
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.

Lisbon Homes and What They Need
Lisbon's median home was built in 1973, notably newer than neighboring Lewiston or Auburn, with about 23 percent of units predating 1940 and 31 percent predating 1960 -- a mix of the old Worumbo Mill village core and later mid-to-late-20th-century growth around it. That newer housing still needs regular heat pump maintenance and system checkups as it ages.
Heating and Cooling in Lisbon
Lisbon leans heavily on delivered fuel: about 69 percent of households heat mainly with fuel oil, 14 percent with bottled or tank propane, and 8 percent with electricity, with no confirmed utility natural-gas distribution in town. That makes a boiler installation or oil-to-heat-pump conversion one of the more common calls we get here.

Getting to Know Lisbon
Lisbon grew up around the Worumbo Mill, a woolen manufacturer founded in 1864 that stayed a major local employer until it burned down in 1987. Three waterways run through town -- the Androscoggin River, the Sabattus River, and the Little River -- which shaped where the old mill village and its housing took root.
Lisbon is one of the few towns in the area that names its own Electrical Inspector directly on the town website, rather than routing everything through a general code office. It's also grown noticeably since the mill era: the median home here dates to 1973, meaningfully newer than the mill-city housing stock next door in Lewiston or Auburn.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Lisbon — not a national franchise. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. 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 Lisbon
In Lisbon, plumbing permits come from the Local Plumbing Inspector at the Code Enforcement, Town of Lisbon (Lisbon Town Offices, 300 Lisbon Street, Lisbon, ME 04250, 207-353-3000 ext. 108). With 9,711 residents, Lisbon is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Lisbon is drained by the Androscoggin River along with the Sabattus River and Little River; the Worumbo Mill (founded 1864) was a principal Lisbon employer until it burned in 1987.
- 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 Lisbon
- With heating oil the leading fuel in Lisbon (about 69% of homes), most heat pump installation jobs here are an add-on to an existing system rather than a full replacement — we walk you through both paths.
- 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.

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!

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.
