Ductless Mini-Splits for Bath Homeowners
No Ductwork Required
Zone-by-Zone Control
Whisper-Quiet Operation
Need ductless mini-splits in Bath? Aces Highlands runs out of 508 Riverside St Unit 1 in Portland and covers Sagadahoc 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.

Bath Homes and What They Need
Bath has the oldest housing stock among the Sagadahoc towns Aces serves, with a median build year of 1938 and 57.5 percent of homes dating before 1940 (66.5 percent before 1960). That history traces straight back to the city's shipbuilding boom, and it means downtown and the surrounding historic district carry plenty of original wiring and cast-iron plumbing. Exterior changes in the historic district need Planning Board review under the city's Land Use Code, so a heat pump installation here often starts with figuring out where the outdoor unit can go.
Heating and Cooling in Bath
About 47 percent of Bath households heat mainly with fuel oil, with bottled or tank propane at 20 percent and electricity at nearly 20 percent, and the city sits within Maine Natural Gas's service territory. With so much of the housing stock this old, a boiler repair call is just as likely to turn up a decades-old cast-iron boiler as a newer high-efficiency unit.
Getting to Know Bath
Bath was incorporated as a town in 1781 and chartered as a city in 1847, named after Bath, Somerset, England. Since 1743, roughly 5,000 vessels have been built along its Kennebec River waterfront, including the Wyoming, widely considered the largest wooden ship ever built, launched from the Percy & Small Shipyard.
Bath Iron Works, founded in 1884 by Thomas W. Hyde, has built hundreds of Navy vessels and given the city its 'City of Ships' nickname, one that still fits given how much of the local economy still runs through the shipyard. The Abenaki called the river itself 'Sagadahoc,' meaning the mouth of the big river, which is also where Sagadahoc County gets its name.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Bath under its own name. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. That is how we keep customers calling back, one honest job at a time.
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 Bath
In Bath, plumbing permits come from the Local Plumbing Inspector at the City of Bath Code Enforcement Office (55 Front St., Bath, ME 04530, (207) 443-8330). With 8,815 residents, Bath is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The City sits directly on the tidal Kennebec River; exterior modifications to buildings within the Bath Historic District require Planning Board review (often completed administratively in as little as three days).
- 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 Bath
- With heating oil the leading fuel in Bath (about 47% of homes), most ductless mini-splits jobs here are an add-on to an existing system rather than a full replacement — we walk you through both paths.
- The circuit feeding the outdoor unit is permitted first, and all refrigerant handling follows EPA Section 608 rules — no shortcuts on either.
- 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.

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.
