Heat Pump Maintenance for Berwick Homeowners

When Berwick homeowners need heat pump maintenance, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Berwick in York County — so we respond quickly and know the homes, the weather, and the codes in your area.
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
- Scheduling that moves quickly, because a home without heat or water cannot wait
- Licensed, insured, and background-checked, and reviewed by real customers on Google
Berwick Homes and What They Need
Berwick's median home was built in 1989, with 16 percent of the housing stock predating 1940 and 21 percent predating 1960 -- a newer profile than you might expect from one of Maine's oldest incorporated towns, since most of the historic core split off with South and North Berwick generations ago.
Heating and Cooling in Berwick
About 59 percent of Berwick households heat mainly with fuel oil, with bottled or tank propane at 17 percent and wood at 11 percent. Unlike neighboring North and South Berwick, Berwick itself has no piped natural gas service, which keeps heat pump pairings and propane conversions the more common upgrade paths here.

Getting to Know Berwick
Berwick was incorporated on June 9, 1713, the ninth town incorporated in what is now Maine, on land the Abenaki knew as Newichawannock, or 'river of many falls.' The town used to be much bigger: South Berwick split off in 1814, and North Berwick followed in 1831.
Diamond Hill, at 490 feet, is Berwick's highest point today -- a modest peak in a town whose real distinction is just how long it's been settled, older than the United States itself.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Berwick — not a national franchise. 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
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 Berwick
In Berwick, plumbing permits come from the Local Plumbing Inspector at the Berwick Code Enforcement Office (11 Sullivan Street, Berwick, ME 03901, (207) 698-1101 ext. 122).

- 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 Berwick
- Because roughly 59% of Berwick 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.
- 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.

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.

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!
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.
