Furnace Installation for Cape Elizabeth Homeowners

Cape Elizabeth sits in Cumberland County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for furnace installation gets a technician who already knows the local housing and codes, not a first-timer.
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.

Cape Elizabeth Homes and What They Need
Cape Elizabeth's housing is markedly older than Falmouth's or Cumberland's. Census estimates put the median home at 1967, about two-thirds of homes were built before 1980, and nearly one in five predates 1940, in neighborhoods such as Cape Cottage and Delano Park near Fort Williams. Building has slowed sharply: only about 4 percent of homes date from 2010 or later. Roughly nine in ten are single-family detached houses. Close to half of all homes date from 1940 to 1979, across areas like Pond Cove, Shore Acres and Oakhurst, which means original branch-circuit wiring, two-prong outlets, ungrounded circuits and early panels are still common, often extended piecemeal by later owners. Before adding heat pumps, an induction range or a finished basement to one of these houses, it is worth having the older wiring inspected and brought up to date.
Heating and Cooling in Cape Elizabeth
Oil still dominates in Cape Elizabeth. Census estimates show fuel oil or kerosene heating roughly 64 percent of occupied homes, a higher share than Falmouth or Cumberland, with electricity at about 12 percent, bottled propane at about 11 percent and utility natural gas at about 10 percent; Unitil lists Cape Elizabeth in its Maine gas territory, but mains do not reach every street. The ocean moderates the worst inland cold, but the town is mostly water by area and houses along Shore Road, Two Lights and Kettle Cove take steady wind and salt spray, which matters for outdoor heat pump units, their mounting and their coils. In oil-heated houses with hot-water or steam heat, replacing an aging oil boiler with a high-efficiency unit, paired with heat pumps, is often the practical first step.

Getting to Know Cape Elizabeth
Cape Elizabeth is home to Portland Head Light, completed in 1791 — the first lighthouse finished by the young United States government, commissioned during George Washington's presidency, and still Maine's oldest lighthouse. The town also produced Joan Benoit Samuelson, who won the first-ever women's Olympic marathon in 1984 and founded the TD Beach to Beacon 10K, which finishes at the lighthouse each summer.
Between Fort Williams and the open Atlantic, Cape Elizabeth homes take the full force of coastal wind and salt air — conditions we plan for in every outdoor equipment installation here.
Local & Independent — Not a Franchise
Aces Highlands answers to Cape Elizabeth homeowners directly, not a franchise office somewhere else in the country. 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 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.

Codes & Permits for Furnace Installation in Cape Elizabeth
In Cape Elizabeth, plumbing permits come from the Local Plumbing Inspector at the Cape Elizabeth Code Enforcement Office (320 Ocean House Road, Cape Elizabeth, ME 04107-0060, 207-799-1619).

Cape Elizabeth is a coastal peninsula town with 31.23 sq mi of water area versus 14.70 sq mi of land, including two islands (Ram Island and the 226-acre Richmond Island) — salt-air/coastal exposure is a relevant factor for equipment materials and corrosion (Wikipedia: Cape Elizabeth, Maine).

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!

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.
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.
