AC Installation for Hallowell Homeowners
Heat Pump & Ductless Cooling
Right-Sized for Your Home
Quiet, Efficient Systems
Hallowell sits in Kennebec County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for ac installation gets a technician who already knows the local housing and codes, not a first-timer.
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.

Hallowell Homes and What They Need
Hallowell's median home was built in 1938, with 57 percent of the city's housing dating before 1940 and 64 percent before 1960 -- the oldest stock of any of the four Kennebec towns Aces serves. Much of downtown and the residential blocks around it fall inside the Hallowell Historic District, listed on the National Register since 1970 and covering roughly 450 buildings, about half of them built before 1865. A rewiring job in that district usually means working carefully around original plaster and trim while still bringing the electrical up to code.
Heating and Cooling in Hallowell
About 42 percent of Hallowell households heat mainly with fuel oil, 17 percent with utility gas from Summit Natural Gas of Maine, and 14 percent with electricity, per Census estimates -- a more mixed fuel picture than some of its Kennebec neighbors. That mix means we are regularly quoting side-by-side comparisons between keeping an oil boiler running and switching part of the load to a heat pump.
Getting to Know Hallowell
Hallowell's first European settler, Deacon Pease Clark, arrived from Massachusetts in 1762, and the city takes its name from Benjamin Hallowell, a Boston merchant and one of the Kennebec Proprietors who backed its early development. Between 1783 and 1901, the city launched roughly 50 ships from its Kennebec wharves, part of an economy that also leaned on granite quarrying and ice exports.
In 1875, Hallowell became home to the Maine Industrial School for Girls, the state's first reform school for girls, which stayed open into the 1970s. Downtown still shows off its 19th-century commercial architecture, anchoring a historic district that gives Hallowell one of the best-preserved old riverfronts on the Kennebec.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Hallowell under its own name. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
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 Hallowell
In Hallowell, plumbing permits come from the Local Plumbing Inspector at the Hallowell Code Enforcement Office (1 Winthrop Street, Hallowell, ME 04347, (207) 430-4405 (office) / (207) 446-0316 (cell)). With 2,570 residents, Hallowell is under the 4,000-resident line at which Maine requires a town to enforce MUBEC. The city is bounded by the Kennebec River, which historically produced regular spring flooding that disrupted downtown commerce.
- 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 AC Installation in Hallowell
- With heating oil the leading fuel in Hallowell (about 42% of homes), most AC installation jobs here are an add-on to an existing system rather than a full replacement — we walk you through both paths.
- 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 AC installation before work starts, since the rebate only applies through a Residential Registered Vendor.

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.

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!

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.
