Hallowell Homes and What They Need
Hallowell's median home was built in 1938, with 57 percent of the city's housing dating before 1940 and 64 percent before 1960 -- the oldest stock of any of the four Kennebec towns Aces serves. Much of downtown and the residential blocks around it fall inside the Hallowell Historic District, listed on the National Register since 1970 and covering roughly 450 buildings, about half of them built before 1865. A rewiring job in that district usually means working carefully around original plaster and trim while still bringing the electrical up to code.
Heating and Cooling in Hallowell
About 42 percent of Hallowell households heat mainly with fuel oil, 17 percent with utility gas from Summit Natural Gas of Maine, and 14 percent with electricity, per Census estimates -- a more mixed fuel picture than some of its Kennebec neighbors. That mix means we are regularly quoting side-by-side comparisons between keeping an oil boiler running and switching part of the load to a heat pump.

Getting to Know Hallowell
Hallowell's first European settler, Deacon Pease Clark, arrived from Massachusetts in 1762, and the city takes its name from Benjamin Hallowell, a Boston merchant and one of the Kennebec Proprietors who backed its early development. Between 1783 and 1901, the city launched roughly 50 ships from its Kennebec wharves, part of an economy that also leaned on granite quarrying and ice exports.
In 1875, Hallowell became home to the Maine Industrial School for Girls, the state's first reform school for girls, which stayed open into the 1970s. Downtown still shows off its 19th-century commercial architecture, anchoring a historic district that gives Hallowell one of the best-preserved old riverfronts on the Kennebec.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Hallowell gets treated. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
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 Hallowell
In Hallowell, plumbing permits come from the Local Plumbing Inspector at the Hallowell Code Enforcement Office (1 Winthrop Street, Hallowell, ME 04347, (207) 430-4405 (office) / (207) 446-0316 (cell)). With 2,570 residents, Hallowell is under the 4,000-resident line at which Maine requires a town to enforce MUBEC. Hallowell's public water supply is not drawn from within the city itself but from well fields in neighboring Chelsea — useful context when discussing private wells vs. district water with customers.
- 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 Hallowell
- With heating oil the leading fuel in Hallowell (about 42% of homes), most heat pump repair jobs here are an add-on to an existing system rather than a full replacement — we walk you through both paths.
- 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.
- 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.

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.

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.
