All Brands Serviced
Aces Highlands handles heat pump repair for homeowners throughout Bath. We work out of 508 Riverside St Unit 1 in Portland, a short drive into Sagadahoc County, so response times stay quick and every job benefits from knowing the local housing stock and code requirements.
When your heat pump stops working or is not performing like it should, Aces Highlands provides fast, accurate diagnostics and honest repairs. We fix the actual problem — not just the symptoms.
Heat pump issues can range from simple fixes like a dirty filter or tripped breaker to more complex problems like refrigerant leaks, compressor failures, or control board malfunctions. Our technicians diagnose accurately the first time so you get the right repair without paying for unnecessary parts.
We service all major heat pump brands including GE, Hitachi, Mitsubishi, Daikin, Fujitsu, and LG. We carry common replacement parts to complete most repairs in a single visit. Regular heat pump maintenance can help prevent many common repair issues before they start.
If your heat pump is beyond repair or the cost of fixing it does not make sense, we will tell you honestly and help you evaluate replacement options.

Bath Homes and What They Need
Bath has the oldest housing stock among the Sagadahoc towns Aces serves, with a median build year of 1938 and 57.5 percent of homes dating before 1940 (66.5 percent before 1960). That history traces straight back to the city's shipbuilding boom, and it means downtown and the surrounding historic district carry plenty of original wiring and cast-iron plumbing. Exterior changes in the historic district need Planning Board review under the city's Land Use Code, so a heat pump installation here often starts with figuring out where the outdoor unit can go.
Heating and Cooling in Bath
About 47 percent of Bath households heat mainly with fuel oil, with bottled or tank propane at 20 percent and electricity at nearly 20 percent, and the city sits within Maine Natural Gas's service territory. With so much of the housing stock this old, a boiler repair call is just as likely to turn up a decades-old cast-iron boiler as a newer high-efficiency unit.
Getting to Know Bath
Bath was incorporated as a town in 1781 and chartered as a city in 1847, named after Bath, Somerset, England. Since 1743, roughly 5,000 vessels have been built along its Kennebec River waterfront, including the Wyoming, widely considered the largest wooden ship ever built, launched from the Percy & Small Shipyard.
Bath Iron Works, founded in 1884 by Thomas W. Hyde, has built hundreds of Navy vessels and given the city its 'City of Ships' nickname, one that still fits given how much of the local economy still runs through the shipyard. The Abenaki called the river itself 'Sagadahoc,' meaning the mouth of the big river, which is also where Sagadahoc County gets its name.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Bath gets treated. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. 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 Bath
In Bath, plumbing permits come from the Local Plumbing Inspector at the City of Bath Code Enforcement Office (55 Front St., Bath, ME 04530, (207) 443-8330). With 8,815 residents, Bath is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Part of the City's sewer system uses combined sewers that can overflow during heavy rain, prompting ongoing infrastructure upgrades (e.g., the Harward Street sewer/pump station project).
- 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
- 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
How Aces Highlands Handles Heat Pump Repair in Bath
- Because roughly 47% of Bath 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.
- The circuit feeding the outdoor unit is permitted first, and all refrigerant handling follows EPA Section 608 rules — no shortcuts on either.
- Efficiency Maine rebates only pay out when a Residential Registered Vendor did the install, so we confirm eligibility with you up front — you can check any installer's registration yourself before signing anything.

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.

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.

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.
