Ductless Mini-Splits for Freeport Homeowners

For ductless mini-splits in Freeport, homeowners turn to Aces Highlands: a Portland-based crew (508 Riverside St Unit 1) that is minutes from Cumberland County and already familiar with the homes, climate and codes here.
Ductless mini-split systems provide efficient heating and cooling without the need for ductwork. Aces Highlands installs single and multi-zone mini-split systems for homes that need targeted comfort in specific rooms or areas.
Mini-splits are ideal for additions, finished basements, garages, bedrooms over garages, and older homes without existing ductwork. Each indoor unit operates independently, giving you zone-by-zone temperature control and eliminating the energy waste of heating or cooling unoccupied rooms. If your home also needs new wiring to support the installation, we handle that too.
We install wall-mounted, ceiling cassette, and floor-mounted indoor units depending on your space and preferences. Each installation includes proper sizing, clean line routing, and thorough testing to ensure optimal performance.
Modern ductless systems operate at whisper-quiet levels and include features like programmable schedules, Wi-Fi control, and advanced filtration. We help you choose the right configuration for your home and budget. Explore our financing options to make your mini-split installation affordable.

- A Cumberland County crew that already knows Freeport's streets and housing stock

Freeport Homes and What They Need
Freeport's housing is older and more varied than the outlet strip suggests. Census estimates for 2020-2024 count about 4,250 homes, with a median build year of 1984; roughly one in six predates 1940 and about 44 percent predates 1980, while close to a third went up after 2000. Most are single-family houses. The historic core sits in the old Harraseeket villages of Mast Landing, Porter's Landing and South Freeport, now a National Register district, and a handful of summer places cluster on small lots on Wolfe's Neck and Lower Flying Point. In the village houses it is common to find cast-iron drains, plaster walls and circuits added piece by piece over a century, so careful rewiring in an older Freeport home often matters more than any single new appliance.
Heating and Cooling in Freeport
Heating oil is still the largest single fuel in Freeport, used by about 44 percent of occupied homes in the latest Census five-year estimates. Bottled propane heats roughly 23 percent, electricity about 13 percent, and wood about 7 percent, with a small but notable share of solar. Maine Natural Gas lists Freeport in its service area, and around 8 percent of homes report utility gas, so availability depends on the street. The town sits on the Casco Bay shore, so the salt-water necks tend to run a little milder than the inland side of town, though all of Freeport sees subzero nights. For an oil or propane household, a whole-house heat pump installation can carry most of the season while an existing boiler stays on as backup for the coldest stretch.

Getting to Know Freeport
Freeport's L.L.Bean flagship store has been open 24 hours a day since 1951, when Leon Leonwood Bean famously did away with the keys — for decades the building did not even have locks. The town is also home to the Desert of Maine, a 40-acre expanse of glacial sand exposed when 19th-century overfarming stripped away the topsoil, and to the 1779 Jameson Tavern, long celebrated (though historians debate it) as the "Birthplace of Maine" statehood discussions.
Beyond the outlets, Freeport is a residential town of village homes and peninsula properties — and those homeowners call us for the same honest heating, plumbing, and electrical work we deliver across Cumberland County.
Local & Independent — Not a Franchise
Aces Highlands answers to Freeport homeowners directly, not a franchise office somewhere else in the country. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
How a Ductless Mini-Split Works
- Outdoor condenser — compressor and fan reject or absorb heat
- Line set — refrigerant lines run through the wall sleeve
- Wall sleeve — one small penetration, no ductwork needed
- Indoor wall head — coil and blower
- Warm air — directed by adjustable louvers

Ductless Mini-Splits: Zoning, Placement & Multi-Unit Systems
A ductless mini-split solves a specific problem — heating and cooling a space with no existing ductwork — and it does it with more control over individual rooms than almost any ducted system can offer.

Codes & Permits for Ductless Mini-Splits in Freeport
In Freeport, plumbing permits come from the Local Plumbing Inspector at the Freeport Codes Enforcement (30 Main Street, Freeport, ME 04032, 207-865-4743).

The town center has a historic-preservation-based Design Review District (Town Code Chapter 22) that can affect exterior work/permitting in the village core.
- The electrical circuit that feeds a new heat pump or AC condenser needs an electrical permit, issued by the Electricians' Examining Board or the town's own electrical inspector, before the wiring is installed or altered. maine.gov
- Efficiency Maine offers rebates of up to $9,000 on qualifying heat pumps, but the equipment must be installed by an Efficiency Maine Residential Registered Vendor for the homeowner to receive the rebate. efficiencymaine.com
- Anyone who connects or disconnects gauges or adds/removes refrigerant on a heat pump or air conditioner must hold EPA Section 608 technician certification; the credential does not expire once earned. epa.gov
How Aces Highlands Handles Ductless Mini-Splits in Freeport
- 44% of Freeport households still heat primarily with heating oil, so we size a ductless mini-splits around whatever is already running the house and tell you straight whether it is worth keeping as a cold-snap backup.
- We pull the electrical permit for the new circuit before touching the outdoor unit, and refrigerant handling stays inside EPA Section 608 the whole job.
- Because Efficiency Maine ties its rebates to Residential Registered Vendor status, we go over what your project actually qualifies for before you commit a dollar.

He was very friendly. He gave me an honest explanation on why I shouldn't recharge my A/C unit and what he suggested made much more sense. He really took care of everything. He is very professional, always called me with updates. 5 stars is not enough — I give this company 10 stars.

I've had three HVAC issues over the past two years. Each time I call, Elija or the office picks up the phone, and my problem is fixed in 24 hrs. Their solutions always feel correct and honest. I cannot recommend them more.

Elijah and Highlands Heating & AC were super helpful! Boiler failed over the weekend and Elijah was very responsive and helpful, getting us up and running right away. I would recommend him at HH&AC highly!

We highly recommend Highlands Heating & AC. They are extremely responsive, knowledgeable and do great work. Our boiler stopped working and Elijah was quick to respond after hours on a Friday. He installed a new boiler and heat pump hot water heater.

Ductless Mini-Splits FAQs
Can a mini-split heat a room all winter in Maine?
Yes — cold-climate mini-splits are rated to keep producing heat at -13°F and below, and Maine homes run tens of thousands of them through every winter. Correct sizing and mounting the outdoor unit above snow line are what make the difference.
How much does a ductless mini-split cost installed?
A quality single-zone installation typically runs $4,000–$6,000. Multi-zone systems cost more depending on the number of indoor heads. Efficiency Maine rebates on qualifying systems reduce the net cost, and we quote firm prices up front.
Are mini-splits noisy?
No — modern indoor heads run at whisper-quiet levels on low fan speeds, quieter than a refrigerator, and the compressor noise stays outside. If a mini-split is loud, something is wrong with it.
Do mini-splits need maintenance?
Yes: rinse the indoor filters every few weeks during heavy use, and have the system professionally cleaned and checked once a year — coils, blower wheel, refrigerant charge, condensate drain, and defrost operation.
How long does installation take?
A typical single-zone installation is finished in one day, including electrical connection and full commissioning. Multi-zone projects usually take two to three days.
