Ductless Mini-Splits for Waterboro Homeowners

Need ductless mini-splits in Waterboro? Aces Highlands runs out of 508 Riverside St Unit 1 in Portland and covers York County routinely, which means a technician who already understands the area's homes and permit process shows up, not a stranger learning it on the job.
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.

- We run trucks through Waterboro and the rest of York County routinely, not occasionally

Waterboro Homes and What They Need
Waterboro's housing stock is young for York County, with a median build year of 1983 and only about 6 percent of homes predating 1940. The mix runs from older lake cottages around Little Ossipee Lake and Lake Arrowhead to newer year-round homes built as the town's population nearly tripled between 1970 and 1990. Heat pump installation on a converted lake cottage is one of our more common calls here.
Heating and Cooling in Waterboro
About two-thirds of Waterboro households heat mainly with fuel oil, with bottled or tank propane at 14 percent and wood at 10 percent; there is no piped natural gas utility in town. That heavy oil reliance makes Waterboro a strong candidate for pairing existing heat with a heat pump.

Getting to Know Waterboro
Waterboro incorporated on March 6, 1787, as 'Waterborough,' shortening to its current name in 1895. Little Ossipee Lake, at 564 acres, is the town's largest body of water, and Waterboro also shares a border with Lake Arrowhead -- the community whose development drove the town's population from about 1,208 in 1970 to nearly 8,000 by 2020.
That growth wasn't always smooth: the 'Great Fires of 1947' burned through roughly three-quarters of the town's land area and destroyed about 90 percent of its lakeside cottages. Today Waterboro also protects the 2,140-acre Waterboro Barrens, a preserved pitch pine barren that's one of the more unusual landscapes in York County.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Waterboro — not a national franchise. Nobody on our crew works on commission, so there is no incentive to sell you more than the job 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.

Codes & Permits for Ductless Mini-Splits in Waterboro
In Waterboro, plumbing permits come from the Local Plumbing Inspector at the Waterboro Code Enforcement Office (Jason Sevigny, Code Enforcement Officer) (24 Townhouse Road, East Waterboro, ME 04030, (207) 247-6166 Ext. 121). With 8,055 residents, Waterboro is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Much of the lakeside housing stock predates the 1980s Lake Arrowhead subdivision boom and may need electrical/plumbing brought up to current code.
- 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
- 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
How Aces Highlands Handles Ductless Mini-Splits in Waterboro
- Because roughly 66% of Waterboro homes are already on heating oil, a ductless mini-splits usually means deciding how much of the heating load the new equipment should carry, not ripping out what's there.
- 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.
- 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.

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.

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.

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.

I've had an excellent experience working with them for both electrical and HVAC work as I remodel my 1785 home. I highly recommend them.
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.
