How a Heat Pump Works
- Outdoor unit — fan and compressor extract heat from outside air, even in cold weather
- 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

Installing Heat Pumps in Kittery's Older, Oil-Heated Homes
With 60.2% of Kittery households heating mainly on oil, most installation projects here start with the same decision Sanford and York homeowners face: will the heat pumps take over the season entirely, or supplement the existing boiler? We answer that with a room-by-room load calculation rather than sizing off the old burner's rating, which matters even more in Kittery than in a newer town — the median home here was built in 1965, and 46.3% of the housing stock predates 1960, so wall and attic insulation vary widely from one Kittery street to the next.
Because Unitil supplies piped natural gas to parts of Kittery, the same restriction applies here as in Sanford: a housing unit with an existing gas utility account isn't eligible for Efficiency Maine's whole-home rebate. For the majority of Kittery homes on oil, that's not a factor, but it's worth checking before a homeowner counts on the rebate. The rebate itself, as of mid-2026, requires the heat pumps to be sized for at least 80% of the home's calculated peak load (100% with supplemental heat counted) and to run as primary heat for the full season, with any oil or propane boiler kept only as emergency backup; it pays $1,000 to $3,000 per eligible single-zone outdoor unit by income tier, plus an extra $500 per housing unit for work completed and claimed between March 1 and December 31, 2026. We point homeowners to efficiencymaine.com and our Efficiency Maine rebate guide since program terms can change.
Every new outdoor unit needs its own electrical permit for the dedicated circuit. Kittery's Code Enforcement Department issues electrical permits directly for a $30 base fee under the National Electrical Code, but compliance is certified through a signed Electrical Installation Code Compliance Affidavit from the installing Maine-licensed electrician rather than a named municipal field inspector — it isn't confirmed whether a disputed or failed installation would then fall to the State of Maine's electrical inspection program. We handle that permit and affidavit process as a routine part of every Kittery installation.
Site work in Kittery also has to account for the town's shoreland and flood-hazard rules given how much of the peninsula sits close to the Piscataqua River, Spruce Creek, Spinney Creek or Chauncey Creek — outdoor unit placement near the water can fall under Maine's Shoreland Zoning Act or Kittery's own Flood Hazard Permitting requirements tied to the town's 2024 FEMA floodplain maps. We check a property's shoreland and flood-zone status as part of every site visit rather than assuming a standard pad location will work. For installation work just north, see our York installation page.

Heat Pump Installation Codes & Permits in Kittery
What Maine law and Kittery's own code office require before any work begins.
Permitting authority
Electrical inspection & utility
Kittery's Code Enforcement Department issues electrical permits directly, certified by a signed compliance affidavit from the installing licensed electrician. Electric service runs on Central Maine Power (CMP).
Refrigerant rules
EPA Section 608 of the Clean Air Act (40 CFR Part 82, Subpart F) prohibits intentionally venting refrigerant while installing, maintaining, servicing, repairing or disposing of heat pump or air-conditioning equipment, and requires technicians who handle refrigerant to hold Section 608 certification.
Ventilation code
The 2021 IECC (adopted by MUBEC) caps whole-building air leakage at 3 air changes per hour at 50 pascals for climate zones 3-8 — Maine sits entirely within zones 5-7 — tested via a blower-door test. Combined with ASHRAE 62.2's mechanical ventilation requirement for new construction, this is why many new Maine homes need a dedicated ERV or HRV for code-required fresh air.
What heat pump installation specifically requires
- A new heat pump's outdoor-unit circuit and disconnect require an electrical permit, since dedicated-circuit wiring falls outside the minor-repair-work exemption.
- Some cities layer a separate mechanical/HVAC permit on top of the electrical permit; South Portland's Heating/HVAC Permit requires the contractor's Maine license number and a Fire Department inspection for any 3+ unit building.
- New-construction installs sit inside MUBEC's 2021 IECC/IMC framework, including the 3 ACH50 blower-door cap and ASHRAE 62.2 mechanical-ventilation requirements.
How Southern Maine Heat Pumps Handles It
Every Kittery installation includes the electrical permit for the outdoor unit's dedicated circuit — we schedule the inspection with Kittery Code Enforcement Department ourselves before a technician shows up with equipment. If your address sits in a city that layers on a separate mechanical permit, we pull that one too, so nothing gets flagged at closing or resale.

What Actually Determines a Heat Pump's Installation Day
A heat pump installation looks straightforward from the driveway — an outdoor unit, an indoor head or two, a line set connecting them — but a handful of decisions made before a single bracket goes up are what separate a system that performs for fifteen winters from one that struggles from day one.

Rebates & Guidance
- Rebate
Whole-home rebates climb with household income
Ducted whole-home systems land an Efficiency Maine rebate of $3,000 at any income level, rising to $6,000 for moderate-income households and $9,000 for low-income households. Go the mini-split route instead and the same three tiers apply per outdoor unit — $1,000, $2,000, or $3,000 each — so a job with more than one condenser adds up fast.
Source: Efficiency Maine - News· Dec 31, 2026
An extra $500 shows up for jobs finished by year-end
Any heat pump project wrapped up and claimed between March 1 and December 31, 2026 tacks on an additional $500 per housing unit to whatever rebate tier the household already qualifies for — ask us where your project falls before that window closes.

Two boxes have to be checked for the money to land
Efficiency Maine won't cut a check unless the equipment appears on its rebate-eligible list and whoever installs it is a Residential Registered Vendor — which is how Southern Maine Heat Pumps is set up. There's also a six-month window: the claim paperwork has to be postmarked or emailed in before that clock runs out from the day the job wraps.

Getting to Know Kittery
Kittery was incorporated in 1647, making it the oldest incorporated town in Maine, and its Portsmouth Naval Shipyard on Seavey's Island — established in 1800 as the U.S. Navy's first federal navy yard — has anchored the local economy for more than two centuries. Badger's Island saw some of the first vessels built for the Continental Navy during the Revolutionary War, including the USS Ranger under John Paul Jones.
Nearly a quarter of Kittery's homes predate 1940 and almost half predate 1960, giving the town the oldest housing stock among our York County service area. Fuel oil heats over 60% of homes here, the highest share of any town we serve, which is exactly the profile where a properly sized heat pump conversion delivers the biggest visible drop in a winter fuel bill.

“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.”
