When Standish 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 Standish in Cumberland 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.

Standish Homes and What They Need
Standish, on the southeastern shore of Sebago Lake, is largely rural, and its housing shows it. Census estimates put the median home at 1980, with about half of homes built before 1980 and about 17 percent before 1940, much of the oldest in the villages of Standish Corner, Steep Falls, Sebago Lake Village and Richville. About 7 percent of homes are mobile or manufactured homes, a far higher share than in the towns closer to Portland. Most striking, nearly one in five housing units is held for seasonal or occasional use, largely camps and cottages along the Sebago Lake shore, Standish Neck and Watchic Lake. That mix means a lot of work on homes that were not built for year-round comfort: shallow or exposed plumbing, crawlspaces with no heat, electric baseboard added later, and manufactured homes whose furnaces and ductwork follow their own replacement rules.
Heating and Cooling in Standish
Standish has essentially no natural gas; census estimates show utility gas in well under 1 percent of homes. Instead, fuel oil or kerosene heats about 61 percent of occupied homes and bottled propane about 26 percent, an unusually high propane share, with wood at about 5 percent and electricity under 3 percent. Standish lies well inland, bounded by Sebago Lake on the west and the Saco River to the southwest, so winter nights here tend to run colder than on the coast. With nearly every household paying for delivered fuel, heat pumps are the main route to lower bills, but most homes keep a combustion system for the coldest days. For those, a well-maintained oil or propane boiler remains the backbone, and Aces Highlands holds Maine Master Oil Burner and Propane and Natural Gas Technician licences.

Getting to Know Standish
Standish began as Pearsontown, a township granted in 1750 to veterans of the French and Indian Wars, and was incorporated in 1785 under a new name honoring Captain Myles Standish of Plymouth Colony fame. When rail service reached Sebago Lake Station in 1870, Standish became a gateway for the lake tourism that still defines the area.
Between year-round homes and lakeside camps, Standish properties see big seasonal swings in use — which is why efficient mini-splits that can heat, cool, and be zoned room-by-room are such a natural fit here.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Standish — not a national franchise. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. 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.

How Aces Highlands Handles Heat Pump Installation in Standish
- 61% of Standish 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.

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.
