AC Installation for Bath Homeowners
Heat Pump & Ductless Cooling
Right-Sized for Your Home
Quiet, Efficient Systems
Aces Highlands handles ac installation for homeowners throughout Bath. We work out of 508 Riverside St Unit 1 in Portland, a short drive into Sagadahoc County, so response times stay quick and every job benefits from knowing the local housing stock and code requirements.
Maine summers are getting warmer, and a properly sized air conditioning system keeps your home comfortable through every heat wave. Aces Highlands installs high-efficiency cooling — from whole-home heat pumps to single-room ductless units — sized and installed right the first time.
For most Southern Maine homes, the smartest way to add air conditioning is a cold-climate heat pump: it cools efficiently in summer and heats your home the rest of the year, all from one system. We are certified GE and Hitachi installers and work with every major brand to match your home and budget.
If you only need to cool a few rooms — a bedroom, a finished attic, an addition, or a home office — a ductless mini-split delivers targeted, zone-by-zone cooling without any ductwork. Every install begins with a proper load calculation so your system is sized correctly: an oversized AC short-cycles and leaves humidity behind, while an undersized one never keeps up on the hottest days.
Our cooling installations include indoor and outdoor unit placement, refrigerant line routing, electrical connections, and full performance testing. Many systems require an electrical panel upgrade to support the new load — we handle that in-house as a licensed Maine electrical contractor. Ask about our financing options to make your AC installation more 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
Aces Highlands is a locally owned Portland, Maine company serving Bath — not a national franchise. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. We show up, fix the actual problem, and let the work speak for itself.
How Central Air Conditioning Works
- Condenser — outside, rejects heat picked up indoors
- Compressor — pressurizes the refrigerant gas
- Evaporator coil — at the furnace, absorbs heat from indoor air
- Blower — pushes air across the cold coil
- Cool air — delivered through the ducts

Central AC Installation: What to Know Before You Buy
Air conditioning used to be optional in Maine. Between hotter, more humid summers and homes built tighter for heating efficiency, it's become close to standard — but it's worth understanding what you're actually buying.

Codes & Permits for AC Installation 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). Part of the City's sewer system uses combined sewers that can overflow during heavy rain, prompting ongoing infrastructure upgrades (e.g., the Harward Street sewer/pump station project).
- 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
- 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
How Aces Highlands Handles AC Installation in Bath
- Because roughly 47% of Bath homes are already on heating oil, a AC installation usually means deciding how much of the heating load the new equipment should carry, not ripping out what's there.
- 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.

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.

AC Installation FAQs
How much does AC installation cost in Maine?
A single-zone ductless system — the most common way to add cooling to a Maine home — typically runs $4,000–$6,000 installed. Whole-home multi-zone heat pump systems cost more. Because these systems also heat, Efficiency Maine rebates on qualifying models often apply.
Is a heat pump or central air better for cooling?
For most Maine homes, a ductless heat pump wins: no ductwork required, higher efficiency, and it heats in winter as well as cools in summer. Central air only tends to make sense if your home already has good ductwork from a forced-air furnace.
Will a mini-split dehumidify my house?
Yes — properly sized, a mini-split removes humidity as it cools, and most models also have a dedicated dry mode for muggy days that are not especially hot. Oversized systems dehumidify poorly, which is why we size from a load calculation.
How long does AC installation take?
Single-zone installations are typically completed in one day. Multi-zone or whole-home systems take two to three days, plus any electrical panel work, which our licensed electricians handle within the same project.
Do I need an electrical upgrade to add AC?
Sometimes. Each outdoor unit needs a dedicated circuit, and older 100-amp panels may not have the capacity. We are a licensed Maine electrical contractor as well as an HVAC company, so we evaluate your panel during the estimate and handle any upgrade in-house.
