AC Installation for Standish Homeowners

When Standish 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 Standish in Cumberland 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.

Standish Homes and What They Need
Standish, on the southeastern shore of Sebago Lake, is largely rural, and its housing shows it. Census estimates put the median home at 1980, with about half of homes built before 1980 and about 17 percent before 1940, much of the oldest in the villages of Standish Corner, Steep Falls, Sebago Lake Village and Richville. About 7 percent of homes are mobile or manufactured homes, a far higher share than in the towns closer to Portland. Most striking, nearly one in five housing units is held for seasonal or occasional use, largely camps and cottages along the Sebago Lake shore, Standish Neck and Watchic Lake. That mix means a lot of work on homes that were not built for year-round comfort: shallow or exposed plumbing, crawlspaces with no heat, electric baseboard added later, and manufactured homes whose furnaces and ductwork follow their own replacement rules.
Heating and Cooling in Standish
Standish has essentially no natural gas; census estimates show utility gas in well under 1 percent of homes. Instead, fuel oil or kerosene heats about 61 percent of occupied homes and bottled propane about 26 percent, an unusually high propane share, with wood at about 5 percent and electricity under 3 percent. Standish lies well inland, bounded by Sebago Lake on the west and the Saco River to the southwest, so winter nights here tend to run colder than on the coast. With nearly every household paying for delivered fuel, heat pumps are the main route to lower bills, but most homes keep a combustion system for the coldest days. For those, a well-maintained oil or propane boiler remains the backbone, and Aces Highlands holds Maine Master Oil Burner and Propane and Natural Gas Technician licences.

Getting to Know Standish
Standish began as Pearsontown, a township granted in 1750 to veterans of the French and Indian Wars, and was incorporated in 1785 under a new name honoring Captain Myles Standish of Plymouth Colony fame. When rail service reached Sebago Lake Station in 1870, Standish became a gateway for the lake tourism that still defines the area.
Between year-round homes and lakeside camps, Standish properties see big seasonal swings in use — which is why efficient mini-splits that can heat, cool, and be zoned room-by-room are such a natural fit here.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Standish under its own name. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. Earning the next call, not hitting a sales target, is the entire business plan.
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 Standish
In Standish, plumbing permits come from the Local Plumbing Inspector at the Town of Standish Code Enforcement Office (175 Northeast Road (Route 35), Standish, ME 04084, 207-642-4571). With 10,244 residents, Standish is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Standish sits beside Sebago Lake and is drained by the Presumpscot River (eastern border) and the Saco River (southwestern border), with Watchic Lake also inside town limits — extensive shoreland zoning applies near these waters.
- 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 Standish
- With heating oil the leading fuel in Standish (about 61% 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.
- 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.
- Efficiency Maine rebates only pay out when a Residential Registered Vendor did the install, so we confirm eligibility with you up front — you can check any installer's registration yourself before signing anything.

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.

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.
