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

New Heat Pumps in Standish: Moving Off Propane and Oil
About one in four occupied Standish homes heats with propane, according to the Census Bureau American Community Survey (2020–2024), a far higher share than the county's roughly 14%. That matters for payback. Efficiency Maine's own figures, priced on June 18, 2026 at $3.34 a gallon for propane and 27 cents a kilowatt-hour, show a household saving about $1,387 a year by heating with heat pumps rather than propane. Oil homes, still the majority here, compare differently, and we can walk through your own delivery bills to show where you would land.
Sizing starts from the house, not the tank. Roughly half of Standish homes were built before 1980, and many have had additions, new windows or insulation work since. A Manual J–style load calculation accounts for all of that and gives a design heat loss for each room, so the equipment matches what the house actually needs on its coldest nights. With a 1980 median build year, many houses here predate current energy codes, and a look in the attic or a blower-door test can change the recommendation. Houses with existing forced-air ductwork may suit a ducted heat pump system; houses heated with hot-water baseboard usually take indoor heads, or a mix of ducted and ductless units where an attic or basement allows short duct runs.
As of mid-2026, the whole-home rebate from Efficiency Maine sets two tests: the heat pumps must supply the home's heat for the whole season, and their combined capacity must reach 80% of the design-day load, or 100% once supplemental heat is added in. Any oil or propane furnace or boiler stays only for emergencies. Dual-fuel combinations are excluded. The income-based tiers apply only when the home is the owner's principal residence, which matters in a town with so many seasonal properties. Low- and moderate-income households get $3,000 or $2,000 for each qualifying single-zone condenser, everyone else $1,000, and a bonus $500 per home applies to jobs finished and claimed during the last ten months of 2026. Terms can change; check efficiencymaine.com or read our 2026 heat pump rebate guide.
Lakefront lots bring one more step. Standish has its own shoreland zoning ordinance, and the town's Planning Department reviews shoreland zoning permits, so check with the town before exterior work close to the water. Outdoor units need a stand or bracket high enough to stay clear of drifting snow, with open ground beneath for defrost drainage. Where a camp road is not plowed in winter, we schedule the work for months when trucks can reach the lot. Just to the southeast, see heat pump installation in Gorham, where our shop is based.

Heat Pump Installation Codes & Permits in Standish
What Maine law and Standish's own code office require before any work begins.
Permitting authority
Electrical inspection & utility
Standish names no Local Electrical Inspector on its Code Enforcement listing, so electrical work defaults to the State Electrical Inspector. 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 Standish installation includes the electrical permit for the outdoor unit's dedicated circuit — we file directly with the State Electrical Inspector's program, since Standish has no local electrical inspector of its own 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 Standish
Standish, named for Plymouth Colony's Captain Myles Standish, sits on the southern shore of Sebago Lake — the deepest lake in Maine and the drinking-water source for the Greater Portland region. The Standish Corner Historic District preserves the crossroads village that grew up where two colonial-era roads met.
From Sebago Lake Village cottages to farmsteads out toward Steep Falls, Standish homes face real inland winters with less coastal moderation than Portland gets. We spec cold-climate units rated for well-below-zero operation here, so the heat keeps coming on the coldest January nights.
Standish Heat Pump Installation FAQs
How much does heat pump installation cost in Standish, Maine?

Efficiency Maine rebates of $1,000 to $3,000 per eligible outdoor unit, depending on household income, can offset part of that; the federal heat pump tax credit ended with 2025.

Yes. The cold-climate Mitsubishi, Daikin, and Samsung systems we install in Standish are engineered to operate efficiently at temperatures well below zero degrees Fahrenheit. Many Standish homeowners use their heat pump as their primary heating source all winter long.
How long does a heat pump installation take in Standish?

“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.”
