When Harpswell 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 Harpswell in Cumberland 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.

Harpswell Homes and What They Need

Harpswell's housing is almost all detached houses, over 90 percent in Census estimates, spread along Harpswell Neck and Orr's, Bailey and Great Island. Of roughly 4,300 homes, about a third are seasonal, many of them old summer cottages on the water. The median build year is 1979; about one in five homes predates 1940, and roughly half predate 1980, while under a fifth were built after 2000. Many started as summer places and were converted to year-round use, which often leaves shallow crawlspaces, piping in unheated spaces and additions wired and plumbed at different times. Salt air adds its own wear to outdoor equipment and fittings. On older island houses, repiping and plumbing upgrades are often part of making a cottage livable through February.

Heating and Cooling in Harpswell

Harpswell heats with oil and propane, since no natural gas mains reach the peninsula. The latest Census five-year estimates show about 44 percent of occupied homes on fuel oil and about 34 percent on propane, one of the highest propane shares in the county, with wood around 9 percent and electricity about 7 percent. Surrounded by Casco Bay, the town is milder than inland Maine in deep winter, but it takes the full force of coastal wind, which matters for heat loss in drafty cottages. A tank of propane or oil also has to arrive over a single road on each neck. For a converted cottage, cold-climate heat pumps can cut delivered fuel, provided the outdoor units are mounted above drifting snow and out of direct salt spray.

Getting to Know Harpswell

Harpswell has more coastline than any other town in Maine — about 216 miles of it, spread across a long peninsula and dozens of islands. It is also home to the Bailey Island Bridge, built in 1927–28 from granite slabs stacked in an open cribwork that lets the tide flow through — the only granite cribstone bridge of its kind in the world.

All that shoreline means nearly every Harpswell home lives with salt air, wind, and weather off the water. We choose equipment and mounting locations accordingly, so systems on Orr's and Bailey Islands last as long as they should.

Local & Independent — Not a Franchise

Aces Highlands is a locally owned Portland, Maine company serving Harpswell — not a national franchise. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. That is how we keep customers calling back, one honest job at a time.

How a Furnace Works

  1. Return air — pulled in through the filter
  2. Blower — pushes air across the heat exchanger
  3. Burners — ignite to heat the exchanger
  4. Heat exchanger — transfers heat without mixing combustion gases
  5. 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.

How Aces Highlands Handles Furnace Installation in Harpswell

  • About 44% of Harpswell homes heat with heating oil today. Oil equipment is installed to NFPA 31, gas and propane to NFPA 54/58, and every vent or chimney tie-in to NFPA 211.
  • Once a furnace installation is finished, we check that carbon monoxide detectors are actually present near the bedrooms — Maine law requires them in any home heated by fuel-burning equipment.

    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.

  • John Walton

    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.

  • Adam Ayan

    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!

  • Susan Donegan

    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.

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.
