AC Installation for Saco Homeowners
Heat Pump & Ductless Cooling
Right-Sized for Your Home
Quiet, Efficient Systems
Saco homeowners call Aces Highlands for ac installation because we are close by, based at 508 Riverside St Unit 1 in Portland, and out on York County roads every day — we know this area's housing, weather and permit process cold.
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.

Saco Homes and What They Need
Saco's housing stock is newer than many of its York County mill-town neighbors: the median home was built in 1982, and only about 22 percent of units predate 1940, with roughly 32 percent predating 1960. That newer mix is one reason we see more calls for routine system upkeep here than for full rewiring jobs.
Heating and Cooling in Saco
About 60 percent of Saco households heat mainly with fuel oil, with electricity at 14 percent and bottled or tank propane at 14 percent; Unitil also serves parts of the city with natural gas. Where gas is available, a gas boiler installation is often the simplest replacement path for an aging oil system.
Getting to Know Saco
Saco was settled in 1631 and cycled through a few names over the centuries, including Winter Harbor and Pepperrellborough, before settling on Saco in 1805 and becoming a city in 1867. It elected its first female mayor, Jodi MacPhail, in November 2023.
The city's York Manufacturing Company, once a major textile employer, closed for good in 1958, and Saco has grown well beyond its mill-town roots since -- it's now part of the Portland-South Portland-Biddeford metro area and home to Thornton Academy and Ferry Beach State Park.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Saco — not a national franchise. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. 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 Saco
In Saco, plumbing permits come from the Local Plumbing Inspector at the Saco Code Enforcement Department (300 Main Street, Saco, ME 04072, (207) 284-6983). With 20,819 residents, Saco is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Maine's Mandatory Shoreland Zoning Act applies along the Saco River and Saco's Atlantic coastline, restricting structure placement near the water.
- 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 Saco
- Because roughly 60% of Saco 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.
- The circuit feeding the outdoor unit is permitted first, and all refrigerant handling follows EPA Section 608 rules — no shortcuts on either.
- 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.

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.

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.

Where to begin? These guys hooked up a sauna for me and did an amazing job, it was not a small job. Projects big or small, these guys are my go to. Responsive, reasonably priced, and professional. In a world where it is tough to get good service, I'm thrilled to have these guys in my phone.

This team was called in by my property management company for where I rent. Elijah and his team were professional, clear speaking. Good communicators gave me the real deal. Didn't give any runaround. I trust them and want to use them for my own projects.
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.
