Furnace Maintenance for Scarborough Homeowners

Need furnace maintenance in Scarborough? Aces Highlands runs out of 508 Riverside St Unit 1 in Portland and covers Cumberland County routinely, which means a technician who already understands the area's homes and permit process shows up, not a stranger learning it on the job.
Regular furnace maintenance is the best way to prevent unexpected breakdowns and keep your heating bills in check. Aces Highlands provides thorough annual tune-ups that keep your furnace running safely and efficiently.
Our furnace maintenance service includes filter replacement, burner cleaning and inspection, heat exchanger inspection, safety control testing, blower motor lubrication, thermostat calibration, and a complete combustion analysis.
A cracked heat exchanger is one of the most serious furnace safety issues — it can allow carbon monoxide to enter your living space. Our maintenance inspection includes a careful check for this and all other safety concerns. We also recommend having your boiler maintained at the same time if your home has both systems.
Schedule your furnace tune-up in early fall before the heating season. Catching small issues early prevents mid-winter breakdowns and keeps your system running at peak efficiency all season long. Contact us to book your annual tune-up.

- We run trucks through Scarborough and the rest of Cumberland County routinely, not occasionally
- Pricing you see up front and a diagnosis you can trust — never a sales pitch
- Same-week scheduling for most service calls
- 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
We are an independent, Portland-based company, not a franchise chain routing your Scarborough job to a call center. Our technicians are not commissioned salespeople and nobody here is required to upsell you anything. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
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

Annual Furnace Maintenance: The Real Checklist
Furnace maintenance is the most commonly skipped HVAC service, largely because a furnace can run for years with no visible sign it's overdue — until the one cold morning it doesn't.

Codes & Permits for Furnace Maintenance 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.
- A carbon monoxide detector must be present in each area within or giving access to a bedroom in the applicable occupancy types under 25 MRSA §2468, regardless of whether the furnace burns oil or gas. mainelegislature.org
- Oil-fired furnaces fall under the same Maine Fuel Board Oil Burner Technician licensing (Apprentice/Journeyman/Master) as oil boilers. maine.gov
- Installing, repairing, or servicing a propane or natural gas furnace requires a Maine Fuel Board Propane and Natural Gas Technician license, with separate authorizations depending on BTU size and scope of work. mainelegislature.org
How Aces Highlands Handles Furnace Maintenance 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.
- We don't close out a furnace maintenance without confirming CO detectors are installed near sleeping areas, which Maine requires wherever the heat comes from burning fuel.

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!

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.

Furnace Maintenance FAQs
How often should a furnace be serviced?
Once a year — ideally in late summer or early fall before the heating season. Oil furnaces especially should never skip a year, since soot buildup and nozzle wear steadily degrade efficiency and reliability.
How often should I change my furnace filter?
Check monthly during heating season and replace every 1–3 months depending on filter type, pets, and dust. A clogged filter is the single most common cause of furnace short-cycling and overheat shutdowns we see.
How much does a furnace tune-up cost?
Typically $150–$400 depending on fuel type, with oil furnaces toward the top because the service includes a new nozzle, oil filter, and full soot cleaning. We quote up front and run seasonal specials on our coupons page.
What happens if I skip furnace maintenance?
Efficiency drops as dirt accumulates, small failures go unnoticed until they strand you without heat, manufacturer warranty coverage can lapse, and safety issues — cracked heat exchangers, venting problems, CO — go undetected. Skipping maintenance does not save money; it defers it with interest.
Will you inspect for carbon monoxide?
Yes. Every tune-up includes a heat exchanger inspection and a combustion analysis that measures CO directly. We also recommend every home with fuel-burning equipment keep working CO detectors on each level.
