Furnace Installation for Scarborough Homeowners

Aces Highlands handles furnace installation for homeowners throughout Scarborough. We work out of 508 Riverside St Unit 1 in Portland, a short drive into Cumberland County, so response times stay quick and every job benefits from knowing the local housing stock and code requirements.
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.

- A straight diagnosis and a clear price before we touch anything — no upsell
- Most calls get on the schedule the same week you reach out
- Licensed, insured, and background-checked, with a track record of Google reviews from real jobs
Scarborough Homes and What They Need
Scarborough is largely a late-20th-century town. Census estimates put the median home at 1988, with only about 8 percent of units built before 1940 and roughly 30 percent built since 2000. About seven in ten homes are single detached houses and more than three quarters are owner-occupied. The older stock clusters in beach villages such as Pine Point, Higgins Beach and Prouts Neck, where cottages built for summer use have often been converted to year-round living, while subdivisions fill the land around Dunstan, Oak Hill and North Scarborough. The newest layer is The Downs, a mixed-use neighborhood rising on the old racetrack site with apartments, condos and single-family homes. Newer houses usually come with ductwork, which makes a ducted heat pump installation straightforward, while converted cottages often need insulation, freeze protection and wiring brought up to date first.
Heating and Cooling in Scarborough
Heating in Scarborough leans on delivered fuels. Census estimates show about 48 percent of occupied homes on fuel oil or kerosene and about 19 percent on bottled propane - a high propane share for a town this close to Portland - with about 15 percent on electricity and about 13 percent on utility gas. Unitil's Northern Utilities serves the town, but gas mains follow the more built-up corridors rather than every road. The town spans a large tidal marsh and several river mouths, so the beach villages feel the ocean's moderating effect while North Scarborough, farther inland, can run colder on clear winter nights. Salt air along Pine Point and Higgins Beach shortens the life of outdoor coils and cabinets. Propane households have a real choice between a high-efficiency gas furnace replacement and a cold-climate heat pump that uses the existing ducts.

Getting to Know Scarborough
Scarborough is one of Maine's oldest towns — incorporated on July 14, 1658 — and it is home to Scarborough Marsh, the largest contiguous saltwater marsh in the state. The town's Prouts Neck peninsula is where the painter Winslow Homer lived and produced many of his famous seascapes.
All that tidal coastline means Scarborough homes deal with real salt-air exposure. It is why we pay close attention to equipment placement and corrosion resistance on every outdoor condenser and heat pump we install near the water.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Scarborough gets treated. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. Earning the next call, not hitting a sales target, is the entire business plan.
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.

How Aces Highlands Handles Furnace Installation in Scarborough
- Where Northern Utilities, Inc. d/b/a Unitil serves the street in Scarborough, gas equipment is usually the simplest furnace installation option; elsewhere we quote oil, propane and heat-pump alternatives side by side.
- With 48% of Scarborough on heating oil, most furnace installation calls here follow NFPA 31 (oil), NFPA 54/58 (gas/propane) or NFPA 211 (venting), depending on what's already installed.
- Part of finishing a furnace installation is verifying CO alarm coverage near bedrooms, the standard Maine sets for homes with fuel-fired heat like a furnace.

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.

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.

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.
