Furnace Installation for Lebanon Homeowners

For furnace installation in Lebanon, homeowners turn to Aces Highlands: a Portland-based crew (508 Riverside St Unit 1) that is minutes from York County and already familiar with the homes, climate and codes here.
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.
Why Lebanon Calls Aces Highlands
- York County is our backyard, and Lebanon is on that route every week
- Honest diagnostics and transparent pricing — no upselling
- Scheduling that moves quickly, because a home without heat or water cannot wait
- Properly licensed and covered by insurance; Google reviewers back up the work
Lebanon Homes and What They Need
Lebanon has the newest median housing stock of the York County towns Aces studied, built in 1989, with the lowest pre-1940 share at about 14 percent. Most of that growth happened after 1980, which means a lot of Lebanon's systems are reaching the age for their first major replacement rather than a full historic rebuild.
Heating and Cooling in Lebanon
Fuel oil and wood together heat the large majority of Lebanon homes -- about 67 percent on oil and 15 percent on wood, the highest combined oil-and-wood share of any town in this group -- with bottled or tank propane at 16 percent; there is no natural gas utility in town. That wood-and-oil combination is a natural fit for adding a heat pump to carry the shoulder seasons.

Getting to Know Lebanon
Lebanon was incorporated on June 17, 1767, making it Maine's 23rd incorporated town, and Wikipedia describes it plainly as 'the westernmost town in Maine.' It borders Acton, Sanford, Berwick and North Berwick on the Maine side, and Milton and Rochester, New Hampshire, on the other.
The town's population grew from about 1,150 in 1930 to more than 6,400 by 2020, with most of that growth arriving after 1980. Lebanon is drained by the Little River and the Salmon Falls River, the latter forming part of the state line with New Hampshire.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Lebanon — not a national franchise. Technicians are not on commission, so the recommendation you get is the one your house actually needs. Earning the next call, not hitting a sales target, is the entire business plan.
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 Lebanon
In Lebanon, plumbing permits come from the Local Plumbing Inspector at the Lebanon Code Enforcement Office (Rod Furbush, Code Enforcement Officer) (15 Upper Guinea Road, Lebanon, ME 04027, (207) 457-6082 option 2). With 6,629 residents, Lebanon is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The Little River and the Salmon Falls River (bordering New Hampshire) run through Lebanon and fall under state shoreland zoning.
- 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
- Propane and natural gas equipment and dispensing installations in Maine must comply with NFPA 54 (National Fuel Gas Code) and NFPA 58 (Liquefied Petroleum Gas Code). maine.gov
How Aces Highlands Handles Furnace Installation in Lebanon
- With 67% of Lebanon 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.
- Once a furnace installation 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.

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 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.
