Heat Pump Maintenance for Lewiston Homeowners
Annual Tune-Up Service
Filter Cleaning & Replacement
Performance Testing
Lewiston homeowners call Aces Highlands for heat pump maintenance because we are close by, based at 508 Riverside St Unit 1 in Portland, and out on Androscoggin County roads every day — we know this area's housing, weather and permit process cold.
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.
Why Lewiston Calls Aces Highlands
- A Androscoggin County crew that already knows Lewiston's streets and housing stock
- You get the real problem and a firm number, not a pitch for extras
- A short wait for a truck, not a long one — most jobs move fast
- Licensed, insured, and background-checked; Google reviewers back up the work
Lewiston Homes and What They Need
Lewiston's median home was built in 1957, with about 32 percent of the housing stock dating before 1940 and 54 percent before 1960 -- a mill-city profile concentrated in the tenement and triple-decker neighborhoods that grew up around the Bates Mill complex in the late 1800s and early 1900s. That density and age combination means plumbing work in older Lewiston buildings often has to account for shared walls and stacked units, not just a single-family layout.
Heating and Cooling in Lewiston
About 53 percent of Lewiston households heat mainly with fuel oil, 23 percent with utility gas, and 10 percent with electricity, per Census estimates, though Lewiston is not in Summit Natural Gas of Maine's published service area, so that utility-gas share likely reflects an older, more limited local distribution system rather than a modern buildout. Either way, a lot of Lewiston's oil-heated multi-unit buildings are strong candidates for a heat pump retrofit.
Getting to Know Lewiston
Lewiston grew up around Lewiston Falls on the Androscoggin River, which started powering the Bates Manufacturing Company's mill complex in 1852. For roughly three decades, Bates was Maine's single largest employer, and it stayed one of Lewiston's biggest employers well into the 20th century, a scale of industry that shaped the city's dense, mill-town neighborhoods.
The Androscoggin River still forms Lewiston's western border, separating it from twin city Auburn, and the two towns share more than a river: Lewiston draws its water through the jointly run Auburn Water District. That kind of shared infrastructure is common between the two cities, a legacy of how closely their industrial histories are tied together.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Lewiston gets treated. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. We show up, fix the actual problem, and let the work speak for itself.
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 Lewiston
In Lewiston, plumbing permits come from the Local Plumbing Inspector at the Planning & Code Enforcement, City of Lewiston (27 Pine Street, Lewiston, ME 04240, 207-513-3000). With 37,121 residents, Lewiston is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The city's Electrical Services Division jointly operates a UV/chemical disinfection facility with the Auburn Water District for the shared Lewiston/Auburn water supply, reflecting how closely the two cities' utilities are intertwined.
- 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 Lewiston
- With heating oil the leading fuel in Lewiston (about 53% of homes), most heat pump maintenance jobs here are an add-on to an existing system rather than a full replacement — we walk you through both paths.
- 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 maintenance 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.

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.
