Heat Pump Repair for Kennebunk Homeowners

Kennebunk sits in York County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for heat pump repair gets a technician who already knows the local housing and codes, not a first-timer.
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.

- We tell you what is actually wrong and what it costs, plainly, every time

Kennebunk Homes and What They Need
Kennebunk has the newest median home of the five York County coastal towns Aces studied, built in 1983, with under 19 percent of units predating 1940 and about 30 percent predating 1960. That newer stock still runs plenty of aging original heating and electrical systems worth a checkup.
Heating and Cooling in Kennebunk
About 56 percent of Kennebunk households heat mainly with fuel oil, with bottled or tank propane at 18 percent and electricity at 15 percent; Unitil also supplies natural gas to parts of town. Where gas is available, a gas boiler installation is often the simplest upgrade from an old oil system.

Getting to Know Kennebunk
Kennebunk broke off from Wells and Arundel to incorporate as its own town on June 24, 1820; the name comes from an Abenaki word describing 'the long cut bank.' Its Summer Street Historic District, home to the Federal-style Wedding Cake House, was the very first historic district in Maine listed on the National Register of Historic Places.
Kennebunk is also the hometown of U.S. Senator and Secretary of State Edmund Muskie and headquarters to Tom's of Maine. Since December 1893, part of town has been served by the Kennebunk Light & Power District, one of only two municipally owned Light & Power Districts left in the state.
Local & Independent — Not a Franchise
Aces Highlands answers to Kennebunk homeowners directly, not a franchise office somewhere else in the country. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. 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 Kennebunk
In Kennebunk, plumbing permits come from the Local Plumbing Inspector at the Kennebunk Code Enforcement Office (Community Development Department) (Kennebunk Town Hall, 2nd Floor, 1 Summer Street, Kennebunk, ME 04043, (207) 985-2102 ext. 1303). With 11,820 residents, Kennebunk is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Kennebunk's Summer Street Historic District was the first historic district in Maine listed on the National Register of Historic Places, which can add review requirements for exterior work in that area.

- 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 Kennebunk
- 56% of Kennebunk households still heat primarily with heating oil, so we size a heat pump repair around whatever is already running the house and tell you straight whether it is worth keeping as a cold-snap backup.
- 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.

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.

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.
