Our Approach to Heat Pump Installation
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.
Do Heat Pumps Really Work in Maine Winters?
Yes — when the right equipment is installed the right way. Modern cold-climate heat pumps are rated to deliver full heating output well below zero, and Maine now has more heat pumps per household than almost any state in the country. The catch is that the technology only performs when the system is sized from an actual load calculation, the outdoor unit is mounted above snow depth with proper drainage, and the refrigerant lines are run and charged correctly. That installation quality — not the brand on the box — is what separates a heat pump that carries a Maine January from one that struggles.
Many of our customers keep their existing boiler or furnace as a backup for the deepest cold snaps, which also keeps fuel-delivery minimums satisfied. Others go all-in on heat pumps for the whole home. We will walk you through both approaches honestly, including what each one does to your operating costs, before you spend a dollar.
How Much Does Heat Pump Installation Cost?
A single-zone ductless installation typically lands in the $4,000–$6,000 range, while multi-zone and whole-home systems run higher depending on zones, line-set lengths, and electrical work. We give you a firm written quote before work begins — no surprise line items on the final invoice.
Maine homeowners also have real money on the table: Efficiency Maine offers rebates on qualifying cold-climate heat pump installations, and federal tax credits may apply. We help you understand what your project qualifies for, and our financing options can spread the remainder over time. Because we are a local company rather than a franchise, our pricing reflects our actual costs — not a national brand fee baked into every job.
What Happens on Installation Day?
Most single-zone installations are complete in one day. Our crew mounts the indoor head and outdoor unit, routes and insulates the refrigerant line set in clean line-hide, makes the electrical connection (including a panel upgrade if your service needs the capacity — we are licensed electricians, so it happens in the same project), pressure-tests and evacuates the lines, and commissions the system in both heating and cooling modes. We walk you through the remote, the maintenance schedule, and the paperwork for your rebate before we leave, and we take the packaging with us.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company — not a national franchise. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. We do the work you called us for, do it right, and earn the next call. That is the whole business model.

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.
