AC Installation for Brunswick Homeowners

Brunswick homeowners call Aces Highlands for ac installation because we are close by, based at 508 Riverside St Unit 1 in Portland, and out on Cumberland County roads every day — we know this area's housing, weather and permit process cold.
Maine summers are getting warmer, and a properly sized air conditioning system keeps your home comfortable through every heat wave. Aces Highlands installs high-efficiency cooling — from whole-home heat pumps to single-room ductless units — sized and installed right the first time.
For most Southern Maine homes, the smartest way to add air conditioning is a cold-climate heat pump: it cools efficiently in summer and heats your home the rest of the year, all from one system. We are certified GE and Hitachi installers and work with every major brand to match your home and budget.
If you only need to cool a few rooms — a bedroom, a finished attic, an addition, or a home office — a ductless mini-split delivers targeted, zone-by-zone cooling without any ductwork. Every install begins with a proper load calculation so your system is sized correctly: an oversized AC short-cycles and leaves humidity behind, while an undersized one never keeps up on the hottest days.
Our cooling installations include indoor and outdoor unit placement, refrigerant line routing, electrical connections, and full performance testing. Many systems require an electrical panel upgrade to support the new load — we handle that in-house as a licensed Maine electrical contractor. Ask about our financing options to make your AC installation more affordable.

- Diagnostics come first, upsells do not — the invoice matches the quote
- Most calls get on the schedule the same week you reach out
- Properly licensed and covered by insurance, with a track record of Google reviews from real jobs
Brunswick Homes and What They Need
Brunswick has the most mixed housing in this part of the coast. Census estimates count about 9,500 homes with a median build year of 1982; roughly 20 percent were built before 1940 and nearly half before 1980. Only about half are detached single-family houses, since the town also has apartments, college housing and mobile homes, about one in eight units. The Federal and Victorian streets near Bowdoin and downtown are the oldest, while the McKeen Street neighbourhood, built for Navy families in the 1950s and 60s, was sold off as some 230 homes after the air station closed. Each era brings its own wiring: knob-and-tube and fuse boxes can still turn up in the old core, and base houses carry services sized for 1950s loads. A panel upgrade in a Brunswick home is often needed before adding heat pumps or an EV charger.
Heating and Cooling in Brunswick
Brunswick has more natural gas than most Maine towns. Maine Natural Gas is based in the town and serves it, and about 21 percent of occupied homes heat with utility gas, according to the latest Census five-year estimates. Oil still leads at about 45 percent, with propane near 15 percent and electricity around 13 percent. Brunswick sits at the head of Maquoit and Middle Bays with the Androscoggin River along its north edge, so the downtown is less exposed than Harpswell's islands but still sees subzero nights. Where a gas line is already at the house and the old unit is due for replacement, a high-efficiency gas furnace or a heat pump paired with the existing system are both reasonable paths.

Getting to Know Brunswick
Brunswick is home to Bowdoin College, chartered in 1794 as Maine's first college. Harriet Beecher Stowe wrote "Uncle Tom's Cabin" while living on Federal Street in 1851, and Joshua Chamberlain — the Bowdoin professor turned Civil War hero who accepted the Confederate infantry's surrender at Appomattox — later served as Maine's governor and Bowdoin's president. The former Naval Air Station is now Brunswick Landing, one of Maine's largest business and technology campuses.
Brunswick's Federal-era and Victorian homes around the college are beautiful — and demanding. Panel upgrades, careful rewiring, and heating systems that respect historic construction are everyday work for our crew here.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Brunswick — 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 Central Air Conditioning Works
- Condenser — outside, rejects heat picked up indoors
- Compressor — pressurizes the refrigerant gas
- Evaporator coil — at the furnace, absorbs heat from indoor air
- Blower — pushes air across the cold coil
- Cool air — delivered through the ducts
Homeowner Guide
Central AC Installation: What to Know Before You Buy
Air conditioning used to be optional in Maine. Between hotter, more humid summers and homes built tighter for heating efficiency, it's become close to standard — but it's worth understanding what you're actually buying.

Codes & Permits for AC Installation in Brunswick
In Brunswick, plumbing permits come from the Local Plumbing Inspector at the Planning & Codes Office, Town of Brunswick Dept. of Planning and Development (85 Union Street, Brunswick, ME 04011, 207-725-6660). With 21,756 residents, Brunswick is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Brunswick applies a Shoreland Protection Overlay (including a Resource Protection subdistrict) and a Special Flood Hazard Area overlay near the Androscoggin/Casco Bay shoreline; the town's Local Plumbing Inspector can approve reduced setbacks for replacement subsurface wastewater systems with a state-licensed soils evaluator's report.
- 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 AC Installation in Brunswick
- Because roughly 45% of Brunswick homes are already on heating oil, a AC installation usually means deciding how much of the heating load the new equipment should carry, not ripping out what's there.
- 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.

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.

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!

Where to begin? These guys hooked up a sauna for me and did an amazing job, it was not a small job. Projects big or small, these guys are my go to. Responsive, reasonably priced, and professional. In a world where it is tough to get good service, I'm thrilled to have these guys in my phone.
AC Installation FAQs
How much does AC installation cost in Maine?
A single-zone ductless system — the most common way to add cooling to a Maine home — typically runs $4,000–$6,000 installed. Whole-home multi-zone heat pump systems cost more. Because these systems also heat, Efficiency Maine rebates on qualifying models often apply.
Is a heat pump or central air better for cooling?
For most Maine homes, a ductless heat pump wins: no ductwork required, higher efficiency, and it heats in winter as well as cools in summer. Central air only tends to make sense if your home already has good ductwork from a forced-air furnace.
Will a mini-split dehumidify my house?
Yes — properly sized, a mini-split removes humidity as it cools, and most models also have a dedicated dry mode for muggy days that are not especially hot. Oversized systems dehumidify poorly, which is why we size from a load calculation.
How long does AC installation take?
Single-zone installations are typically completed in one day. Multi-zone or whole-home systems take two to three days, plus any electrical panel work, which our licensed electricians handle within the same project.
Do I need an electrical upgrade to add AC?
Sometimes. Each outdoor unit needs a dedicated circuit, and older 100-amp panels may not have the capacity. We are a licensed Maine electrical contractor as well as an HVAC company, so we evaluate your panel during the estimate and handle any upgrade in-house.
