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 independently owned and based in greater Portland, with no franchise territory map dictating how Brunswick gets treated. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. 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

Codes & Permits for Heat Pump 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). Brunswick is at the head of tide on the Androscoggin River at the north end of Casco Bay, giving parts of town coastal/tidal exposure (Wikipedia).
- 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 Heat Pump Repair in Brunswick
- Because roughly 45% of Brunswick homes are already on heating oil, a heat pump repair usually means deciding how much of the heating load the new equipment should carry, not ripping out what's there.
- We pull the electrical permit for the new circuit before touching the outdoor unit, and refrigerant handling stays inside EPA Section 608 the whole job.
- We flag which Efficiency Maine incentives apply to a heat pump repair 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!

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.

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 Repair FAQs
Why is my heat pump covered in ice?
Light frost on the outdoor coil is normal — the unit runs periodic defrost cycles to clear it. Solid ice that never clears is not normal, and usually points to a failed defrost sensor or board, low refrigerant, or blocked airflow. Shut the unit off and have it diagnosed before the ice damages the fan or coil.
Why is my heat pump blowing cold air in heat mode?
Check the remote is actually in heat mode and the filters are clean first. If those are fine, the usual causes are low refrigerant from a leak, a failing reversing valve, or a compressor issue — all of which need a technician with gauges to confirm.
How much does heat pump repair cost?
Simple fixes like condensate clogs, sensors, or capacitors are commonly a few hundred dollars. Board replacements and refrigerant leak repairs cost more, and we always quote before we repair, so you can decide with the real number in front of you.
Do you service heat pumps you did not install?
Yes. We repair all major brands — GE, Hitachi, Mitsubishi, Daikin, Fujitsu, LG and others — regardless of who installed the system.
Is it worth repairing a 10-year-old heat pump?
Often yes, if the repair is minor and the system was installed well. Past 12–15 years or facing a compressor or major refrigerant repair, replacement usually makes more financial sense — especially with Efficiency Maine rebates lowering the cost of a new system. We give you both numbers and let you choose.
