Furnace Maintenance for York Homeowners

When York homeowners need furnace maintenance, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from York in York County — so we respond quickly and know the homes, the weather, and the codes in your area.
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.

York Homes and What They Need
York's housing stock is largely mid-to-late 20th century, with a median build year of 1977 and about 22 percent of homes predating 1940. The town's large land area and coastal villages support a big seasonal and vacation-home population alongside year-round residents, which shows up as a wide range of system ages and quality on our service calls.
Heating and Cooling in York
About 55 percent of York households heat mainly with fuel oil, and a notably higher-than-average 22 percent use bottled or tank propane, consistent with no piped natural gas utility currently reaching York. That propane reliance makes a tankless water heater on propane a popular choice here.

Getting to Know York
York was first settled in 1624 as Agamenticus, and Sir Ferdinando Gorges chartered it as 'Gorgeana' in 1642 -- a charter sometimes cited as the first incorporated city in what is now the United States. It was reincorporated as York in 1652 under the Massachusetts Bay Colony, making it the second-oldest incorporated town in Maine, just two years behind Kittery.
A photograph of York's Cape Neddick 'Nubble' Light is included on the Voyager 1 Golden Record, labeled simply 'Seashore, Maine.' The town became a fashionable summer resort after the Civil War and still shows off Gilded Age, shingle-style architecture across its historic districts.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving York — not a national franchise. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. That is how we keep customers calling back, one honest job at a time.
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 York
In York, plumbing permits come from the Local Plumbing Inspector at the York Code Enforcement Office (186 York Street, York, ME 03909, (207) 363-1002). With 13,986 residents, York is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Maine's Mandatory Shoreland Zoning Act applies along York's extensive coastline and rivers (York River, Cape Neddick River), restricting structure placement near the water.
- Maine's adopted 2021 International Mechanical Code (part of MUBEC) sets installation, clearance, and venting requirements for furnaces in municipalities that enforce the code. maine.gov
- 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
How Aces Highlands Handles Furnace Maintenance in York
- About 55% of York 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 maintenance 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.

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.

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!

Where to begin? These guys hooked up a sauna for me and did an amazing job, it was not a small job. Projects big or small, these guys are my go to. Responsive, reasonably priced, and professional. In a world where it is tough to get good service, I'm thrilled to have these guys in my phone.
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.
