Furnace Installation for Kennebunkport Homeowners

When Kennebunkport homeowners need furnace installation, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Kennebunkport in York County — so we respond quickly and know the homes, the weather, and the codes in your area.
When it is time for a new furnace, Aces Highlands helps you choose and install a high-efficiency system that delivers dependable heat and lower energy costs. Every installation includes proper sizing, clean ductwork connections, and thorough testing.
We install oil, propane, and natural gas furnaces from trusted brands. Modern high-efficiency furnaces can operate at 95% efficiency or higher, meaning more of your fuel dollar goes toward heating your home instead of going up the chimney. You might also want to consider a heat pump system for even greater efficiency and year-round comfort.
Proper sizing is critical for furnace performance. An oversized furnace short-cycles and creates temperature swings, while an undersized unit runs constantly without reaching comfortable temperatures. We perform a load calculation to determine the right size for your home.
Our furnace installations include removal of the old unit, new furnace installation, ductwork inspection and connection, thermostat setup, and a complete system test. Older homes may also benefit from an electrical panel upgrade to support the new system. We make sure everything is working perfectly before we leave.
Why Kennebunkport Calls Aces Highlands
- Local team minutes from Kennebunkport, serving all of York County
- Pricing you see up front and a diagnosis you can trust — never a sales pitch
- Scheduling that moves quickly, because a home without heat or water cannot wait

Kennebunkport Homes and What They Need
Kennebunkport's median home was built in 1982, with about 13 percent of units predating 1940 and 29 percent predating 1960 -- a mix of early-1900s shingle-style cottages in the Cape Arundel Summer Colony Historic District alongside newer coastal construction. Those older cottages are prime candidates for a heat pump retrofit that extends comfortable use into the shoulder seasons.
Heating and Cooling in Kennebunkport
About half of Kennebunkport households heat mainly with fuel oil, with bottled or tank propane at 27 percent and electricity at 20 percent; there is no piped natural gas in town. With propane this common, a tankless water heater on propane is a popular upgrade for a seasonal cottage being used more of the year.

Getting to Know Kennebunkport
Kennebunkport was first incorporated in 1653 as Cape Porpus, renamed Arundel in 1701, and finally took its current name in 1821 to reflect a growing shipbuilding and trading economy. Walker's Point, the Bush family's summer estate here, has hosted world leaders including Margaret Thatcher and Mikhail Gorbachev.
Cape Porpoise remains a working fishing harbor village within the town, keeping its own restaurants, church, library and commercial fleet. The Cape Arundel Summer Colony Historic District, running from Chick's Creek to Walker's Point, is full of early-1900s shingle-style summer cottages that still define much of the town's coastline.
Local & Independent — Not a Franchise

How a Furnace Works
- Return air — pulled in through the filter
- Blower — pushes air across the heat exchanger
- Burners — ignite to heat the exchanger
- Heat exchanger — transfers heat without mixing combustion gases
- Supply air — warm air delivered to the home

Furnace Installation: Sizing, Ductwork & Venting
A furnace replacement is a chance to fix problems the original installation may have never addressed — most of which live in the ductwork, not the furnace cabinet.

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.

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!

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!
Furnace Installation FAQs
How much does a new furnace cost installed?
Most residential furnace replacements run roughly $5,000–$9,000 installed depending on fuel type, efficiency class, and ductwork condition. We provide a firm written quote before ordering equipment, and financing is available.
How long does furnace installation take?
A straightforward replacement is completed in one day, with heat restored the same evening. Jobs involving significant ductwork, venting changes, or fuel conversion may take a second day.
What size furnace does my home need?
The size should come from a heat-loss calculation of your actual home — insulation, windows, air sealing, square footage — not from copying the old unit’s label. Oversized furnaces short-cycle and create temperature swings; undersized ones run constantly and still fall behind.
Should I replace my furnace with a heat pump instead?
Worth considering. Cold-climate heat pumps heat efficiently through most of a Maine winter and add air conditioning, and Efficiency Maine rebates may apply. Many homes pair a heat pump with a furnace as backup. We install both, so we can price the options against each other honestly.
Do you remove the old furnace?
Yes — removal and disposal of the old unit is included in every installation, along with a full cleanup of the work area.
