Furnace Installation for York Homeowners

York sits in York County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for furnace installation gets a technician who already knows the local housing and codes, not a first-timer.
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.

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
We are an independent, Portland-based company, not a franchise chain routing your York job to a call center. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. We show up, fix the actual problem, and let the work speak for itself.
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.

Codes & Permits for Furnace Installation 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 Installation in York
- With 55% of York 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.
- We don't close out a furnace installation without confirming CO detectors are installed near sleeping areas, which Maine requires wherever the heat comes from burning fuel.

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'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.

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.
