Southern Maine Heat Pumps proudly serves homeowners and businesses throughout Hallowell and Kennebec County. One of Maine's smallest cities, Hallowell has the oldest housing stock in Kennebec County, and its well-preserved 19th-century downtown demands the same careful, low-profile equipment placement we use on any historic Maine streetscape. From downtown Hallowell, the Kennebec riverfront, the Hallowell Historic District to the surrounding area, we design and install cold-climate systems from Mitsubishi, Daikin, and Samsung that are rated to operate efficiently down to -13°F. Our most requested service in Hallowell is heat pump installation, the single highest-value upgrade for comfort and energy savings.
Because we are based just down the road in Gorham, Hallowell residents count on us for responsive service and honest advice. We install ductless mini-splits for homes without ductwork, handle replacements and upgrades of aging equipment, and guide you through every Efficiency Maine rebate available.

Hallowell Heat Pumps: Older Homes, Oil Heat
Southern Maine Heat Pumps installs and services cold-climate heat pump systems throughout Hallowell, Kennebec County, from downtown Hallowell, the Kennebec riverfront, and the Hallowell Historic District to the rest of town. Hallowell's roughly 2,570 residents (Census Bureau American Community Survey, 2020-2024) rely on a heating mix that still leans heavily on delivered fuel and electricity rather than piped gas in most cases.
Housing here skews old: 57% of homes predate 1940 and 64.1% predate 1960, per the Census Bureau's American Community Survey (2020-2024). Pre-war construction usually means original wiring and plumbing that a heat pump project has to work around rather than assume.
Fuel oil/kerosene leads the way at 42.2% of occupied homes, with utility gas next at 17.4%. Piped gas from Summit Natural Gas of Maine reaches part of Hallowell, but it isn't the majority fuel here.
Hallowell falls in IECC climate zone 6 along with nearly every other Maine town, so the cold-climate ratings on the equipment we install aren't a marketing label here — they're the actual design target for a real Hallowell winter.
On the permitting side, Hallowell's Code Enforcement Officer is listed as Building Inspector and Local Plumbing Inspector with no electrical title, so the state performs electrical inspections. CMP supplies electric service throughout town.
Permit questions for this kind of work in Hallowell run through Hallowell Code Enforcement Office (https://hallowell.govoffice.com/index.asp?SEC=4142410B-21F2-4FF0-A84C-FB46A1ED2F72); we check the current requirements ourselves rather than assuming they haven't changed. With about 2,570 residents spread from downtown Hallowell and the Kennebec riverfront outward, no two Hallowell homes have identical electrical service, so every quote starts with an in-home visit rather than a guess over the phone.
Most Hallowell projects start with heat pump installation or ductless mini-splits for a home with no existing ductwork, and grow from there into replacement, water heating or ventilation work as needed.
From our base in Gorham, our family-owned team installs and services Mitsubishi, Daikin and Samsung systems across Kennebec County, and as an Efficiency Maine Residential Registered Vendor we handle the rebate paperwork for you.

Getting to Know Hallowell
Hallowell's first European settler, Deacon Pease Clark, arrived from Massachusetts in 1762, and the city is named for Benjamin Hallowell, a Boston merchant and Kennebec Proprietor. Between 1783 and 1901 the city launched about 50 ships from its Kennebec River wharves, and downtown Hallowell's roughly 450-building historic district — about half built before 1865 — has been on the National Register since 1970.
More than 57% of Hallowell's homes predate 1940, the oldest housing stock of any Kennebec County town in our service area, all sitting along a stretch of the Kennebec River with a long history of spring flooding. Fuel oil heats 42% of households, utility gas 17% through Summit Natural Gas, and electricity 14%, a more even three-way split than most towns we serve, which usually means a heat pump conversion here has to be evaluated fuel by fuel rather than assumed.

“Nate did a nice, professional job cleaning and servicing our heat pump. We recommend and will use them again.”
Justin Spear

“I had neglected annual service out of fear that it would cost a fortune but when I called to make the appointment, they let me know what was included in service and the cost- amazing! I appreciated that they were willing to service the system even though they did not do the installation.”
Ben Winkler
April 2026
“I contacted Southern Maine Heat Pumps to service my two units. The technicians who came out to service our heat pumps did an outstanding job. They were very thorough and helpful. They did a way better job than what I have experienced before with other maintenance services.”
Matt Heer
March 2026
“The technician arrived right on time, diagnosed the issue quickly, and had both of my heat pumps running smoothly in no time. They explained everything clearly and didn’t try to upsell unnecessary services — just honest, quality work. The price was fair, and the customer service was exceptional.”
Sarah McKay

“I was being serviced by another local company as I had a crack in my Daikin Drip Pan. The previous company came out 3 times and finally diagnosed it. They ordered the part and then never showed up again even though the part was under warranty. I found Southern Maine on a google search and gave them a call. Sam called my back immediately.”
