Heat Pump Installation for South Berwick Homeowners

South Berwick homeowners call Aces Highlands for heat pump installation because we are close by, based at 508 Riverside St Unit 1 in Portland, and out on York County roads every day — we know this area's housing, weather and permit process cold.
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.

South Berwick Homes and What They Need
South Berwick's housing stock runs older than most of its York County neighbors, with a median build year of 1982 and 22 percent of homes predating 1940. The National Register-listed village center includes 18th-century homes like the Hamilton House and the Sarah Orne Jewett House, where rewiring work has to be done carefully around original construction.
Heating and Cooling in South Berwick
About 60 percent of South Berwick households heat mainly with fuel oil, with bottled or tank propane at 20 percent. A small reported share of "utility gas" in Census data does not match any confirmed piped natural gas provider serving the town, so we treat South Berwick as an oil-and-propane market rather than one with real gas-main access.

Getting to Know South Berwick
South Berwick was set off from Berwick and incorporated on its own on February 12, 1814. Author Sarah Orne Jewett was born here in 1849, and her family's 1774 home still stands in the village, alongside the Federal-style Hamilton House, built around 1785.
The town's village center was added to the National Register of Historic Places in 2010, and nearby Vaughan Woods State Park gives South Berwick a mix of preserved history and open land along the Salmon Falls and Great Works rivers.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how South Berwick gets treated. 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 South Berwick
In South Berwick, plumbing permits come from the Local Plumbing Inspector at the South Berwick Code Enforcement Office (Alan Plummer, Code Enforcement Officer / Licensed Plumbing Inspector / Health Officer) (180 Main Street, South Berwick, ME 03908 (2nd floor of Town Hall), 207-384-3301).

- 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 South Berwick
- With heating oil the leading fuel in South Berwick (about 60% 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.
- 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.

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.

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.

This team was called in by my property management company for where I rent. Elijah and his team were professional, clear speaking. Good communicators gave me the real deal. Didn't give any runaround. I trust them and want to use them for my own projects.

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.
