Boiler Installation for Scarborough Homeowners

Scarborough 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 boiler installation gets a technician who already knows the local housing and codes, not a first-timer.
Aces Highlands installs high-efficiency boiler systems designed to keep your home warm through the toughest Maine winters. Every installation is properly sized, cleanly piped, and thoroughly tested before we leave.
We install oil, propane, and natural gas boilers from trusted manufacturers including Viessmann, Buderus, and Weil-McLain. Our installations feature clean copper piping, properly insulated lines, and professional workmanship that speaks for itself.
Every boiler installation starts with a heat loss calculation to determine the right size system for your home. An oversized boiler wastes fuel and short-cycles, while an undersized system cannot keep up in cold weather. We get the sizing right. Pair your new boiler with a radiant floor heating system for the ultimate in comfort.
We handle complete system installations including boiler placement, piping, zone controls, expansion tanks, and all necessary safety devices. Our work meets or exceeds all applicable codes and manufacturer specifications. Ask about our financing plans for new boiler installations.

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 a locally owned Portland, Maine company serving Scarborough — not a national franchise. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. That is how we keep customers calling back, one honest job at a time.
How a Boiler Works
- Burner — ignites fuel to heat the exchanger
- Heat exchanger — heats the water circulating in the loop
- Circulator pump — pushes hot water through the loop
- Expansion tank — absorbs pressure as water heats and expands
- Baseboard loop — hot water out, cooler water returns

Boiler Installation: Sizing, Piping & the Details That Matter
A boiler replacement is one of the few HVAC jobs where reusing the existing piping layout without checking it can quietly undercut the new equipment's performance.

Codes & Permits for Boiler Installation in Scarborough
In Scarborough, plumbing permits come from the Local Plumbing Inspector at the Town of Scarborough Planning & Codes Department (Scarborough Municipal Building, Lower Level Room 125, 259 U.S. Route 1, Scarborough, ME 04070 (mailing: PO Box 360, Scarborough, ME 04070-0360), 207-730-4040). With 22,135 residents, Scarborough is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Scarborough has significant Gulf of Maine/Saco Bay coastline, including the Prouts Neck, Pine Point, and Higgins Beach neighborhoods, plus Scarborough Marsh — meaning salt-air exposure and marsh/shoreland conditions are a live factor for coastal work.
- Chimneys and vents serving fuel-fired appliances, including hydronic boilers, are governed by NFPA 211, the standard for chimneys, fireplaces, and vents. maine.gov
- State law requires a carbon monoxide detector in each area within or giving access to a bedroom wherever a fuel-burning heating appliance like a boiler serves a covered dwelling. mainelegislature.org

How Aces Highlands Handles Boiler Installation in Scarborough
- Northern Utilities, Inc. d/b/a Unitil has mains through parts of Scarborough, so a gas-fired swap is on the table wherever a line already reaches the street; off that grid the choice is oil, propane or a heat pump.
- About 48% of Scarborough 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.
- Part of finishing a boiler installation is verifying CO alarm coverage near bedrooms, the standard Maine sets for homes with fuel-fired heat like a boiler.

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.

Boiler Installation FAQs
How long does a boiler last in Maine?
A well-maintained cast-iron boiler commonly runs 20–30 years; high-efficiency condensing boilers typically last 15–20. Annual maintenance is the biggest factor — a neglected boiler gives up years early, a serviced one keeps going.
How much does boiler replacement cost?
Most full residential replacements in Southern Maine land between $7,000 and $12,000 installed, depending on fuel type, efficiency class, and the piping and venting work involved. We provide a firm written quote before any work begins, and financing is available.
How long will I be without heat during the swap?
Most replacements are completed in one to two days, and we plan the changeover so your home is without heat for the shortest window possible — usually just part of one working day.
Should I convert from oil to propane or natural gas?
It depends on fuel availability at your address, your current equipment’s age, and long-term fuel pricing. Conversions unlock quiet, compact high-efficiency boilers, but they carry added venting and fuel-line costs. We install oil, propane, and gas systems, so our recommendation is not biased toward any one answer.
What boiler brands do you install?
We install trusted manufacturers including Viessmann, Buderus, and Weil-McLain, and we match the brand and model to your system design rather than pushing a single house brand.
