AC Installation for North Yarmouth Homeowners

For ac installation in North Yarmouth, homeowners turn to Aces Highlands: a Portland-based crew (508 Riverside St Unit 1) that is minutes from Cumberland County and already familiar with the homes, climate and codes here.
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.

North Yarmouth Homes and What They Need
North Yarmouth grew from fewer than 1,000 residents in 1950 to about 4,100 in 2020, and its housing shows that growth. Census estimates count about 1,600 homes, nearly all detached single-family houses, with a median year built of 1981. About 17 percent predate 1940, mostly farmhouses and capes around Walnut Hill and along Routes 9, 115 and 231, while subdivisions from the 1970s through the 2010s fill in the land between them. Homes here are also valued higher than in the other inland towns nearby, with a median owner-estimated value near $480,000, and close to nine in ten are owner-occupied. The result is a large group of 30- to 45-year-old houses whose original heating systems, water heaters and panels are reaching the end of their service life, and a furnace replacement in a forced-air home is a natural moment to add central cooling or a heat pump coil.
Heating and Cooling in North Yarmouth
Census estimates put fuel oil or kerosene as the main heat in about six in ten North Yarmouth homes, but propane is unusually strong here at close to 20 percent, with electricity around 9 percent and wood around 6 percent. Utility gas reaches only about 4 percent of homes; Summit Natural Gas has built mains in neighbouring Yarmouth and Cumberland, but most of North Yarmouth's rural roads are not piped. The town lies a few miles inland from Casco Bay, and inland towns typically see colder, calmer winter nights than the shore. For propane-heated homes, the comparison between a high-efficiency propane appliance and a cold-climate heat pump system usually comes down to the price of a gallon of propane against a kilowatt-hour, and a hybrid setup that lets the heat pump run most of the season and the propane unit cover the coldest stretches is a common middle path.

Getting to Know North Yarmouth
North Yarmouth is one of the oldest towns in Maine — the original 1680 plantation of "Ancient North Yarmouth" was a mother town whose territory included present-day Cumberland, Yarmouth, Chebeague Island, Pownal, Freeport, Harpswell, and part of Brunswick. One by one those communities were set off, leaving the quiet inland town that carries the original name today.
That long history shows in North Yarmouth's housing — classic farmhouses and capes alongside newer homes — and we bring the same care to a 200-year-old post-and-beam as to new construction.
Local & Independent — Not a Franchise
Aces Highlands answers to North Yarmouth homeowners directly, not a franchise office somewhere else in the country. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. We show up, fix the actual problem, and let the work speak for itself.
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 North Yarmouth
In North Yarmouth, plumbing permits come from the Local Plumbing Inspector at the Town of North Yarmouth Code Enforcement Office (10 Village Square Road, North Yarmouth, ME 04097, (207) 829-3705 ext. 206). With 4,072 residents, North Yarmouth is required to enforce the Maine Uniform Building and Energy Code (MUBEC). North Yarmouth has no village sewer system, so septic design/setback review is a routine part of most renovation and new-construction permits.
- 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 North Yarmouth
- 60% of North Yarmouth 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.
- 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.

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.

I've had an excellent experience working with them for both electrical and HVAC work as I remodel my 1785 home. I highly recommend them.
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.
