Furnace Maintenance for New Gloucester Homeowners

Aces Highlands handles furnace maintenance for homeowners throughout New Gloucester. 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.
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.

New Gloucester Homes and What They Need
New Gloucester has about 2,300 homes spread across 47 square miles, and the stock spans more than two centuries. Census estimates put the median year built at 1987, yet roughly one in nine homes predates 1940, many of them in the historic village along the old county road, in Upper Gloucester and around the Shaker community at Sabbathday Lake. Most of the rest are single-family houses from the 1970s onward on rural frontage lots, and about 8 percent are manufactured homes, a larger share than in neighbouring Gray. Old farmhouses with ells and attached barns tend to carry plumbing and wiring from several eras, added room by room over the decades, so an older house can hide undersized circuits or early wiring behind later updates. A wiring assessment and rewire before adding heat pumps, an electric range or an EV charger avoids surprises.
Heating and Cooling in New Gloucester
New Gloucester leans on heating oil harder than most of its neighbours. Census estimates show close to 70 percent of occupied homes burn fuel oil or kerosene as their main heat, about 11 percent propane, about 10 percent wood and only around 7 percent electricity; under 2 percent report utility gas, and no natural gas main serves the town's rural roads. The town sits well inland in the Royal River valley at an elevation of about 360 feet, far enough from Casco Bay that winter nights run colder than on the coast. That fuel mix makes oil-to-electric conversion a big opportunity here, but a careful one. A farmhouse with a single oil boiler and a few cold rooms often does best with a ductless mini-split in the main living space and the boiler kept for hot water and the deepest cold snaps.

Getting to Know New Gloucester
New Gloucester is home to Sabbathday Lake Shaker Village, established in 1783 — the last active Shaker community in the world. Its 1794 meetinghouse still stands, the village is a National Historic Landmark, and a small number of practicing Shakers continue the tradition there today.
That deep history means New Gloucester has some genuinely old homes alongside rural properties running on oil and propane — exactly the kind of housing where a carefully planned heat pump conversion or boiler upgrade pays off, and where we do a lot of our work.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving New Gloucester — not a national franchise. 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 New Gloucester
In New Gloucester, plumbing permits come from the Local Plumbing Inspector at the New Gloucester Code Enforcement Office (385 Intervale Road, New Gloucester, ME 04260, (207) 926-4126 x3). With 5,676 residents, New Gloucester is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The town's water district serves only the Upper Village, created specifically to address groundwater contamination there — most other properties in town are on private wells.
- 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 New Gloucester
- Unitil has mains through parts of New Gloucester, 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 68% of New Gloucester 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.

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 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.
