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.

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.

Biddeford Homes and What They Need
Biddeford's housing stock runs old: the median home was built in 1952, with about 41 percent of units predating 1940, reflecting the mill-era rowhouses and multi-family buildings that went up through the early 20th century. That density and age combination means rewiring a Biddeford multi-family often involves tracing circuits that were added or changed unit by unit over the decades.
Heating and Cooling in Biddeford
About 64 percent of Biddeford households heat mainly with fuel oil, with bottled or tank propane at 13 percent and electricity at 12 percent; Unitil also runs natural gas mains through parts of the city. Where a gas line already reaches the street, a furnace replacement can be a straightforward gas conversion; elsewhere we are typically pairing a heat pump with the existing oil system.

Getting to Know Biddeford
Biddeford's roots go back to the winter of 1616-17, when European settlers first arrived at Biddeford Pool -- roughly four years before the Mayflower landed at Plymouth. Once incorporated as Saco in 1653, it reorganized under the Biddeford name in 1718 and was chartered as a city in 1855.
The Saco River drops about 40 feet over falls in Biddeford, power that once ran one of New England's largest textile mill complexes, employing as many as 12,000 people before the last mill finally closed in 2009. The city covers about 59 square miles, nearly half of it water, with roughly 15 miles of river and Atlantic frontage at Biddeford Pool and Fortunes Rocks.
Local & Independent — Not a Franchise
We are an independent, Portland-based company, not a franchise chain routing your Biddeford job to a call center. Technicians are not on commission, so the recommendation you get is the one your house actually needs. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
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 Biddeford
In Biddeford, plumbing permits come from the Local Plumbing Inspector at the Biddeford Code Enforcement Office (205 Main Street (enter near the City Theater), Biddeford, ME 04005, (207) 284-9236). With 22,498 residents, Biddeford is required to enforce the Maine Uniform Building and Energy Code (MUBEC).

- 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 Biddeford
- With heating oil the leading fuel in Biddeford (about 64% 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.

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.
