Ductless Mini-Split Installation
in Raymond, Maine

With more than a third of Raymond's housing units not anyone's usual residence, a large share of the town's buildings are cottages and camps, typically with open living rooms, a sleeping loft, board or knotty-pine interiors, crawlspaces or posts instead of full basements, and no ductwork anywhere. A ductless mini-split fits that kind of building well. One head high on a gable wall can heat and cool an open main room, and a second small head can handle a loft or back bedroom that never gets air from the rest of the house.

Winterizing a camp in stages is common, and ductless systems let you do it the same way. You might start with a single-zone unit in the main room, then add heads for bedrooms after the walls and floor are insulated. For owners who leave for part of the winter, a heat pump can hold the building at a low setpoint instead of relying on a space heater or draining everything down, though plumbing protection still depends on insulation and how the pipes are run.

Rebate eligibility changes with how you use the place. As of mid-2026, Efficiency Maine's low- and moderate-income tiers require the home to be the owner's principal residence, so a seasonal cottage generally falls under the any-income amount of $1,000 per eligible single-zone outdoor unit. If you are converting a cottage into your year-round home, the timing of that change matters, and we can walk through it with you. Program terms can change, so confirm at efficiencymaine.com.

For houses with several small rooms, multi-zone heat pump systems can run two to five heads off one outdoor unit and keep the exterior uncluttered, which many lakefront owners prefer on the water side. Lofts under cathedral ceilings deserve extra thought: warm air collects near the peak, so a head mounted too high can satisfy its own sensor while the main floor stays cool. Depending on where people actually sit, a floor-mounted console can serve better than a high-wall unit. In summer, a well-placed head also pulls moisture from damp lake air, which helps with the musty smell many camps pick up. We mount outdoor units on the side of the building that stays clear of roof avalanches and plowed snow, and we run line sets in covers painted or matched to the siding.
