Heat Pump Maintenance for Waterboro Homeowners

Aces Highlands handles heat pump maintenance for homeowners throughout Waterboro. We work out of 508 Riverside St Unit 1 in Portland, a short drive into York County, so response times stay quick and every job benefits from knowing the local housing stock and code requirements.
Regular maintenance keeps your heat pump running efficiently and extends its lifespan. Aces Highlands provides thorough tune-up service that catches small issues before they become expensive problems.
Our heat pump maintenance service includes cleaning indoor and outdoor coils, checking refrigerant levels, inspecting electrical connections, testing defrost cycles, cleaning or replacing filters, and verifying overall system performance.
Maine weather puts extra demands on heat pumps. Ice buildup, debris around outdoor units, and seasonal transitions all affect performance. Regular maintenance ensures your system is ready for both heating and cooling seasons.
We recommend annual maintenance for most heat pump systems. A well-maintained heat pump uses less energy, heats and cools more evenly, and lasts years longer than a neglected one. Schedule your tune-up before the season changes.

- A straight diagnosis and a clear price before we touch anything — no upsell
- A short wait for a truck, not a long one — most jobs move fast
- Licensed and insured; Google reviewers back up the work
Waterboro Homes and What They Need
Waterboro's housing stock is young for York County, with a median build year of 1983 and only about 6 percent of homes predating 1940. The mix runs from older lake cottages around Little Ossipee Lake and Lake Arrowhead to newer year-round homes built as the town's population nearly tripled between 1970 and 1990. Heat pump installation on a converted lake cottage is one of our more common calls here.
Heating and Cooling in Waterboro
About two-thirds of Waterboro households heat mainly with fuel oil, with bottled or tank propane at 14 percent and wood at 10 percent; there is no piped natural gas utility in town. That heavy oil reliance makes Waterboro a strong candidate for pairing existing heat with a heat pump.

Getting to Know Waterboro
Waterboro incorporated on March 6, 1787, as 'Waterborough,' shortening to its current name in 1895. Little Ossipee Lake, at 564 acres, is the town's largest body of water, and Waterboro also shares a border with Lake Arrowhead -- the community whose development drove the town's population from about 1,208 in 1970 to nearly 8,000 by 2020.
That growth wasn't always smooth: the 'Great Fires of 1947' burned through roughly three-quarters of the town's land area and destroyed about 90 percent of its lakeside cottages. Today Waterboro also protects the 2,140-acre Waterboro Barrens, a preserved pitch pine barren that's one of the more unusual landscapes in York County.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Waterboro under its own name. Technicians are not on commission, so the recommendation you get is the one your house actually needs. Earning the next call, not hitting a sales target, is the entire business plan.
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
Homeowner Guide
What Annual Heat Pump Maintenance Actually Covers
A heat pump runs harder than a furnace or boiler — it's providing both heating and cooling, often year-round in Maine's shoulder seasons — which is part of why annual maintenance matters more than owners moving from an old furnace tend to expect.

Codes & Permits for Heat Pump Maintenance in Waterboro
In Waterboro, plumbing permits come from the Local Plumbing Inspector at the Waterboro Code Enforcement Office (Jason Sevigny, Code Enforcement Officer) (24 Townhouse Road, East Waterboro, ME 04030, (207) 247-6166 Ext. 121). With 8,055 residents, Waterboro is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Much of the lakeside housing stock predates the 1980s Lake Arrowhead subdivision boom and may need electrical/plumbing brought up to current code.
- 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
- 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
How Aces Highlands Handles Heat Pump Maintenance in Waterboro
- Because roughly 66% of Waterboro homes are already on heating oil, a heat pump maintenance 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.
- 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.

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.

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 Maintenance FAQs
How often should a heat pump be serviced?
Professional maintenance once a year — nearly year-round runtime in Maine justifies it — plus homeowner filter cleaning every few weeks during heavy use. If the system both heats and cools your home hard, twice-yearly service is a reasonable upgrade.
Can I clean my heat pump filters myself?
Yes, and you should. Pop the indoor unit cover, slide out the mesh filters, rinse, dry, and reinstall — every two to four weeks in heavy season. The deeper items — blower wheel, coils, refrigerant charge, defrost testing, electrical — are what the annual professional visit covers.
Why does my heat pump smell musty?
Moisture on a dirty indoor coil and blower wheel grows mildew, producing the well-known "dirty sock" odor. A professional deep clean of the head removes it. Regular filter cleaning and an annual service keep it from coming back.
Does maintenance really lower my electric bill?
Yes. Dirty filters and coils force the compressor to run longer to move the same heat. Restoring clean airflow and verified refrigerant charge returns the system to its rated efficiency — a difference you can see across a Maine heating season.
Do I need to do anything to my heat pump in winter?
Keep the outdoor unit clear: brush off heavy snow, keep ice from building underneath, and never let roof slides bury it. Airflow blockage in winter is one of the most common causes of poor performance and defrost problems we see.
