Furnace Installation for Lewiston Homeowners

For furnace installation in Lewiston, homeowners turn to Aces Highlands: a Portland-based crew (508 Riverside St Unit 1) that is minutes from Androscoggin 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 Lewiston Calls Aces Highlands
- Local team minutes from Lewiston, serving all of Androscoggin County
- A straight diagnosis and a clear price before we touch anything — no upsell
- A short wait for a truck, not a long one — most jobs move fast
- Fully licensed, fully insured — neighbors in Lewiston leave us reviews on Google
Lewiston Homes and What They Need
Lewiston's median home was built in 1957, with about 32 percent of the housing stock dating before 1940 and 54 percent before 1960 -- a mill-city profile concentrated in the tenement and triple-decker neighborhoods that grew up around the Bates Mill complex in the late 1800s and early 1900s. That density and age combination means plumbing work in older Lewiston buildings often has to account for shared walls and stacked units, not just a single-family layout.
Heating and Cooling in Lewiston
About 53 percent of Lewiston households heat mainly with fuel oil, 23 percent with utility gas, and 10 percent with electricity, per Census estimates, though Lewiston is not in Summit Natural Gas of Maine's published service area, so that utility-gas share likely reflects an older, more limited local distribution system rather than a modern buildout. Either way, a lot of Lewiston's oil-heated multi-unit buildings are strong candidates for a heat pump retrofit.

Getting to Know Lewiston
Lewiston grew up around Lewiston Falls on the Androscoggin River, which started powering the Bates Manufacturing Company's mill complex in 1852. For roughly three decades, Bates was Maine's single largest employer, and it stayed one of Lewiston's biggest employers well into the 20th century, a scale of industry that shaped the city's dense, mill-town neighborhoods.
The Androscoggin River still forms Lewiston's western border, separating it from twin city Auburn, and the two towns share more than a river: Lewiston draws its water through the jointly run Auburn Water District. That kind of shared infrastructure is common between the two cities, a legacy of how closely their industrial histories are tied together.
Local & Independent — Not a Franchise
We are an independent, Portland-based company, not a franchise chain routing your Lewiston 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. Getting invited back is the only metric that matters here.
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.

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.
