AC Installation for Auburn Homeowners
Heat Pump & Ductless Cooling
Right-Sized for Your Home
Quiet, Efficient Systems
When Auburn homeowners need ac installation, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Auburn in Androscoggin County — so we respond quickly and know the homes, the weather, and the codes in your area.
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.

Auburn Homes and What They Need
Auburn's median home was built in 1954, with 38 percent of housing dating before 1940 and 57 percent before 1960 -- slightly older on average than Lewiston's stock, concentrated in the shoe- and mill-era neighborhoods that grew up after the city's 1848 rail connection went in. That vintage of housing is exactly where rewiring work tends to turn up knob-and-tube remnants and undersized panels.
Heating and Cooling in Auburn
About 51 percent of Auburn households heat mainly with fuel oil, 22 percent with utility gas, and 11 percent with electricity, per Census estimates -- though Auburn, like Lewiston, is not in Summit Natural Gas of Maine's published service area, so that utility-gas figure likely reflects an older local distribution setup. Either way, plenty of Auburn's oil-heated homes are good candidates for adding a heat pump alongside the existing system.
Getting to Know Auburn
Auburn once had one of the largest shoe industries in the country -- by 1917 the city's factories were turning out roughly 75 percent of the world's supply of white canvas shoes, before the industry faded after World War II. That manufacturing boom is a big part of why Auburn's older neighborhoods look the way they do today.
Auburn sits across the Androscoggin River from Lewiston, and the two cities share more than a border: they draw water together through the Auburn Water District, and the Little Androscoggin River cuts through Auburn as well. Auburn also runs its own municipal Electrical Department, which both maintains the city's traffic signals and streetlights and handles the city's electrical code inspections.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Auburn gets treated. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. Getting invited back is the only metric that matters here.
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 Auburn
In Auburn, plumbing permits come from the Local Plumbing Inspector at the Planning, Permitting & Code, City of Auburn (60 Court Street, Auburn, ME 04210 (Auburn City Hall), (207) 333-6600). With 24,061 residents, Auburn is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Auburn's water utility (Auburn Water District, drawing on Lake Auburn) supplies both Auburn and Lewiston, and the city coordinates with the Lake Auburn Watershed Commission on development near the source lake.
- 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 AC Installation in Auburn
- 51% of Auburn households still heat primarily with heating oil, so we size a AC installation around whatever is already running the house and tell you straight whether it is worth keeping as a cold-snap backup.
- The circuit feeding the outdoor unit is permitted first, and all refrigerant handling follows EPA Section 608 rules — no shortcuts on either.
- We flag which Efficiency Maine incentives apply to a AC installation before work starts, since the rebate only applies through a Residential Registered Vendor.

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.
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.
