AC Installation for Lisbon Homeowners
Heat Pump & Ductless Cooling
Right-Sized for Your Home
Quiet, Efficient Systems
Lisbon sits in Androscoggin 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.

Lisbon Homes and What They Need
Lisbon's median home was built in 1973, notably newer than neighboring Lewiston or Auburn, with about 23 percent of units predating 1940 and 31 percent predating 1960 -- a mix of the old Worumbo Mill village core and later mid-to-late-20th-century growth around it. That newer housing still needs regular heat pump maintenance and system checkups as it ages.
Heating and Cooling in Lisbon
Lisbon leans heavily on delivered fuel: about 69 percent of households heat mainly with fuel oil, 14 percent with bottled or tank propane, and 8 percent with electricity, with no confirmed utility natural-gas distribution in town. That makes a boiler installation or oil-to-heat-pump conversion one of the more common calls we get here.
Getting to Know Lisbon
Lisbon grew up around the Worumbo Mill, a woolen manufacturer founded in 1864 that stayed a major local employer until it burned down in 1987. Three waterways run through town -- the Androscoggin River, the Sabattus River, and the Little River -- which shaped where the old mill village and its housing took root.
Lisbon is one of the few towns in the area that names its own Electrical Inspector directly on the town website, rather than routing everything through a general code office. It's also grown noticeably since the mill era: the median home here dates to 1973, meaningfully newer than the mill-city housing stock next door in Lewiston or Auburn.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Lisbon gets treated. 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 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
Homeowner Guide
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 Lisbon
In Lisbon, plumbing permits come from the Local Plumbing Inspector at the Code Enforcement, Town of Lisbon (Lisbon Town Offices, 300 Lisbon Street, Lisbon, ME 04250, 207-353-3000 ext. 108). With 9,711 residents, Lisbon is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The town's sewer system is run directly by Lisbon's own Public Works department rather than a separate regional district, per the town's sewer rate/ordinance pages.
- 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 Lisbon
- Because roughly 69% of Lisbon 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.
- 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.

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.

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.
