AC Repair for Brunswick Homeowners

When Brunswick homeowners need ac repair, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Brunswick in Cumberland County — so we respond quickly and know the homes, the weather, and the codes in your area.
When the cooling quits during a Maine heat wave, you need a technician who diagnoses on the first visit and quotes before starting. Aces Highlands repairs ductless mini-splits, heat pumps in cooling mode, and central air across Greater Portland.
Most Southern Maine cooling is a ductless mini-split or a heat pump in cooling mode, and failures follow a pattern: a weak capacitor, a clogged condensate drain, a dirty coil, a tripped breaker, or a slow refrigerant leak.
We service every major brand — Mitsubishi, Daikin, Fujitsu, LG, GE, and Hitachi — plus conventional central air condensers paired with a furnace. Our vans carry capacitors, contactors, condensate pumps, and common sensors, so most repairs finish in one visit.
If the unit is past 12 years, runs on phased-out R-22 refrigerant, or needs a compressor, we show you the numbers on replacement — an Efficiency Maine rebate on a new cold-climate heat pump can change that math.
Same-week appointments are the norm outside peak heat waves. Call (207) 670-8616, tell us what the unit is doing, and we will say whether it can wait or needs a same-day visit. Regular maintenance prevents most of these calls.

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
We are an independent, Portland-based company, not a franchise chain routing your Brunswick job to a call center. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. Getting invited back is the only metric that matters here.
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

Why Central AC Fails Mid-Summer (And What We Check First)
AC failures cluster on the hottest days for a mechanical reason, not bad luck — a system running at its rated limit for hours on end is when a marginal part finally gives out.

Codes & Permits for AC Repair 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). The town contains multiple National Register historic districts (e.g., Brunswick Commercial, Federal Street, Lincoln Street), where exterior/mechanical work can face added design review (Wikipedia).
- 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 AC Repair in Brunswick
- 45% of Brunswick households still heat primarily with heating oil, so we size a AC repair around whatever is already running the house and tell you straight whether it is worth keeping as a cold-snap backup.
- 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 AC repair before work starts, since the rebate only applies through a Residential Registered Vendor.

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!

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.

AC Repair FAQs
How quickly can you repair my AC in Portland?
Outside of peak heat waves, most cooling repair calls are seen within a few days and often the same week. During a stretch of 90-degree days we prioritize homes with no working cooling at all. Call and tell us what the unit is doing — we will give you a realistic window, not a guess.
Do you repair mini-splits and heat pumps, or only central air?
All three. Most Southern Maine cooling is a ductless mini-split or a heat pump in cooling mode, and those make up the majority of our repair calls. We also service conventional central air condensers paired with a furnace and air handler.
My AC is low on refrigerant — can you just top it up?
A sealed system should never lose refrigerant, so a low charge means a leak. We can add refrigerant to get you through a heat wave, but we will tell you it is temporary. Finding and repairing the leak is the real fix and avoids paying for the same refrigerant every summer.
Should I repair or replace my air conditioner?
Repair a newer system with a single failed part. Replace when the unit is past 12–15 years, uses phased-out R-22 refrigerant, needs a compressor out of warranty, or has needed refrigerant more than one season. Efficiency Maine rebates on qualifying cold-climate heat pumps often tip the decision toward a new system that also heats.
Why does my breaker trip when the AC starts?
Usually a failing capacitor or a compressor drawing too much current on startup — both create a surge the breaker reads as a fault. It can also be a worn breaker or a shared circuit. Stop resetting it repeatedly; each trip stresses the compressor. We diagnose which it is on the first visit.
Do I need a permit for AC repair in Maine?
No. Repairs and part replacements on an existing system do not require a permit. Replacing the outdoor unit or installing a new system does involve electrical permitting and inspection, which we handle in-house as a licensed Maine electrical contractor.
