Need heat pump repair in Winthrop? Aces Highlands runs out of 508 Riverside St Unit 1 in Portland and covers Kennebec County routinely, which means a technician who already understands the area's homes and permit process shows up, not a stranger learning it on the job.
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.

Winthrop Homes and What They Need
Winthrop's median home dates to 1977, per Census estimates, with about 24 percent of housing built before 1940 and 35 percent before 1960 -- newer than neighboring Augusta or Gardiner, which fits a town that grew as a lakes destination rather than around an old mill or river port. That newer stock still means plenty of 1970s- and '80s-era systems reaching the end of their service life. Water heater repair calls on those original units are common.
Heating and Cooling in Winthrop
About 59 percent of Winthrop households heat mainly with fuel oil, 16 percent with wood, and 12 percent with electricity, and there is no natural gas utility in town. Winthrop's population roughly doubles every summer as seasonal camp owners return to its lakeshores, which drives a predictable spring rush of startup and shutdown plumbing work. For a camp that is slowly becoming a year-round home, a cold-climate heat pump paired with the existing oil or wood setup is a common upgrade path.
Getting to Know Winthrop
Winthrop started out in 1765 as a scattering of lakeside homesteads known informally as "Pondtown," then took its current name at incorporation in 1771, honoring Massachusetts's first colonial governor. For roughly 150 years, the Winthrop Mills Company was one of the country's largest woolen-blanket makers and the town's biggest employer -- a scale of industry that is easy to forget looking at Winthrop's lake-town feel today.
One of the more unusual local landmarks is the 'Ladies Delight Light' on Cobbossee Lake, a small lighthouse built in 1908 that is thought to be the only active inland lighthouse anywhere in Maine. The town has also been growing steadily for over a century, from about 2,088 residents in 1900 to 6,121 at the 2020 count, making it the largest town, as opposed to city, in Kennebec County.
Local & Independent — Not a Franchise
We are an independent, Portland-based company, not a franchise chain routing your Winthrop 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. 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 Winthrop
In Winthrop, plumbing permits come from the Local Plumbing Inspector at the Winthrop Code Enforcement Office (17 Highland Avenue, Winthrop, ME 04364, 207-377-7200 ext. 6007). With 6,121 residents, Winthrop is required to enforce the Maine Uniform Building and Energy Code (MUBEC).

- 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 Winthrop
- Because roughly 59% of Winthrop 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.
- 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.

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.

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.
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.
