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
If your heat pump is aging, losing efficiency, or breaking down, Southern Maine Heat Pumps can upgrade your Wells home to a modern, high-efficiency system. We serve York County with complete replacements, from removing and recovering refrigerant out of your old equipment to installing today's far more efficient cold-climate models and completing every rebate form.
Homeowners in Wells Beach, Moody, and Drakes Island and throughout Wells are surprised how much quieter and more efficient new systems run compared to units from even a few years ago. Where possible we reuse existing line sets to keep your upgrade affordable.

Replacing Propane, Wood and Early Heat Pumps in Wells Homes
Wells heats with a wider mix of fuels than most of York County. Census survey estimates for 2020–2024 show oil in about 55% of occupied homes, propane in about 22%, wood in about 5.5% and other fuels in nearly 5%, with electricity at about 11.5%. That mix shapes what an upgrade looks like, because a propane furnace, an oil boiler and a woodstove each leave different questions about backup heat, venting and where the new equipment can go.
For oil and propane homes, the usual path is to install heat pumps as the primary system and keep the existing furnace or boiler for emergency backup only, the arrangement Efficiency Maine's whole-home rebate requires as of mid-2026. Dual-fuel controls that alternate between the two do not qualify. Because only about 1% of Wells homes use utility gas, the rule against a prior natural-gas utility account rarely applies here, but we confirm it before quoting a rebate. Homes that heat mainly with wood, a larger group here than in the neighboring beach towns, can use heat pumps to cover the rooms the stove never reaches and the nights nobody wants to feed it.
Electric baseboard and older ductless units are the other targets. The electricity figure includes both, and baseboard turns up often in part-time houses where low upfront cost mattered more than the monthly bill. Swapping to a cold-climate heat pump uses less electricity for the same heat and adds cooling for summer. When an older ductless unit is replaced, we inspect the existing line set, confirm it is the right size, and pressure test and evacuate it before reuse; anything corroded or kinked is replaced.
The federal 25C tax credit ended for equipment placed in service after December 31, 2025, so Efficiency Maine's rebate is the main incentive, including the extra $500 per housing unit for upgrades completed and claimed by December 31, 2026. Terms can change. Our upgrade and replacement service covers equipment of any brand, and we help with Efficiency Maine Home Energy Loan paperwork.
If a system is repairable, a service call may be the better value than replacing it outright, and we work on every heat pump brand.

Free in-home estimates are available Monday through Saturday, and we look at fuel type, electrical capacity and equipment location on the same visit.

Heat Pump Replacement & Upgrades Codes & Permits in Wells
What Maine law and Wells's own code office require before any work begins.
Permitting authority
Electrical inspection & utility
Wells has no municipal electrical inspector; its Code Enforcement Office directs electrical questions straight to the Maine 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 replacement & upgrades specifically requires
- A like-for-like condenser swap still requires an electrical permit if the circuit, disconnect or wiring is touched.
- Replacement installs completed after January 1, 2025 fall under the AIM Act's Technology Transitions restrictions on newly manufactured high-GWP refrigerant equipment, though EPA has weighed extending the R-410A sell-through window.
How Southern Maine Heat Pumps Handles It
Swapping an old heat pump for a new one in Wells still touches the electrical circuit in most cases, so we file directly with the State Electrical Inspector's program, since Wells has no local electrical inspector of its own. We also confirm your address never held a natural-gas account before assuming any Efficiency Maine rebate applies.

Replacing an Aging Heating System With a Heat Pump
Most replacement projects start with a system that's aging out — an oil furnace nearing 20 years, electric baseboard that's become expensive to run, or an early-generation heat pump that never quite handled a Maine winter well. The upgrade decision usually comes down to three questions: replace like-for-like, go all-electric, or keep something as backup.

Rebates & Guidance
- Rebate
A replacement qualifies the same as a first-time install
Trading in an old heat pump, or moving off oil, propane, or electric baseboard entirely, taps the identical rebate scale as a brand-new project: $3,000 to $9,000 on a ducted system, or $1,000 to $3,000 per outdoor condenser on a mini-split, all scaled by income tier.
Source: Efficiency Maine - Recommendation
The old furnace doesn't have to go anywhere
A fair number of our replacement customers make the heat pump their day-to-day system and leave the old oil or propane furnace sitting there for an especially cold stretch or an outage. That choice doesn't change the rebate math on the heat pump side one bit.

Getting to Know Wells
Incorporated in 1653, Wells is Maine's third-oldest town, named for the English cathedral city and known to the Abenaki as Webhannet, "at the clear stream." Today it's home to the Wells Reserve at Laudholm, a 2,250-acre estuarine research reserve centered on a restored 1880s saltwater farm, with seven miles of trails running from field to salt marsh to barrier beach.
Wells splits between beach neighborhoods — Wells Beach, Moody, Drakes Island — and year-round homes inland along Route 1 and Route 9. For both, heat pumps replace expensive electric-baseboard and propane heat while adding the cooling that packed July rental weeks now practically require.
Wells Heat Pump Replacement & Upgrades FAQs
When should I replace my heat pump in Wells?
If your Wells heat pump is over 10 to 15 years old, needs frequent repairs, struggles to keep up on cold days, or your energy bills are climbing, it is usually worth replacing. We will give you an honest assessment during a free in-home visit.
Can you reuse my existing line set when upgrading in Wells?
In many Wells replacements we can reuse the existing refrigerant line set and mounting, which lowers cost. We inspect everything first and only reuse components that meet manufacturer specifications.
Will a new heat pump lower my bills in Wells?
Yes. Modern high-efficiency heat pumps installed in Wells carry significantly better efficiency ratings than older units, so most homeowners see lower heating and cooling costs along with quieter, more reliable operation.

“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.”
