Ductless Mini-Splits for Scarborough Homeowners

When Scarborough homeowners need ductless mini-splits, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Scarborough in Cumberland County — so we respond quickly and know the homes, the weather, and the codes in your area.
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.

Scarborough Homes and What They Need
Scarborough is largely a late-20th-century town. Census estimates put the median home at 1988, with only about 8 percent of units built before 1940 and roughly 30 percent built since 2000. About seven in ten homes are single detached houses and more than three quarters are owner-occupied. The older stock clusters in beach villages such as Pine Point, Higgins Beach and Prouts Neck, where cottages built for summer use have often been converted to year-round living, while subdivisions fill the land around Dunstan, Oak Hill and North Scarborough. The newest layer is The Downs, a mixed-use neighborhood rising on the old racetrack site with apartments, condos and single-family homes. Newer houses usually come with ductwork, which makes a ducted heat pump installation straightforward, while converted cottages often need insulation, freeze protection and wiring brought up to date first.
Heating and Cooling in Scarborough
Heating in Scarborough leans on delivered fuels. Census estimates show about 48 percent of occupied homes on fuel oil or kerosene and about 19 percent on bottled propane - a high propane share for a town this close to Portland - with about 15 percent on electricity and about 13 percent on utility gas. Unitil's Northern Utilities serves the town, but gas mains follow the more built-up corridors rather than every road. The town spans a large tidal marsh and several river mouths, so the beach villages feel the ocean's moderating effect while North Scarborough, farther inland, can run colder on clear winter nights. Salt air along Pine Point and Higgins Beach shortens the life of outdoor coils and cabinets. Propane households have a real choice between a high-efficiency gas furnace replacement and a cold-climate heat pump that uses the existing ducts.

Getting to Know Scarborough
Scarborough is one of Maine's oldest towns — incorporated on July 14, 1658 — and it is home to Scarborough Marsh, the largest contiguous saltwater marsh in the state. The town's Prouts Neck peninsula is where the painter Winslow Homer lived and produced many of his famous seascapes.
All that tidal coastline means Scarborough homes deal with real salt-air exposure. It is why we pay close attention to equipment placement and corrosion resistance on every outdoor condenser and heat pump we install near the water.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Scarborough under its own name. Technicians are not on commission, so the recommendation you get is the one your house actually needs. Getting invited back is the only metric that matters here.
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.

How Aces Highlands Handles Ductless Mini-Splits in Scarborough
- 48% of Scarborough 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.
- Every outdoor unit we set gets its own permitted circuit before it's wired in, and any refrigerant work is done under our EPA Section 608 certification.
- We flag which Efficiency Maine incentives apply to a ductless mini-splits before work starts, since the rebate only applies through a Residential Registered Vendor.

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.
