Furnace Installation for Augusta Homeowners

Augusta homeowners call Aces Highlands for furnace installation because we are close by, based at 508 Riverside St Unit 1 in Portland, and out on Kennebec County roads every day — we know this area's housing, weather and permit process cold.
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 Augusta Calls Aces Highlands
- Based just outside Augusta and out on Kennebec County calls every day
- We tell you what is actually wrong and what it costs, plainly, every time
- Scheduling that moves quickly, because a home without heat or water cannot wait
- Properly licensed and covered by insurance — neighbors in Augusta leave us reviews on Google
Augusta Homes and What They Need
Census estimates put Augusta's median home at 1965, with close to 29 percent of the city's housing built before 1940 and nearly 45 percent before 1960. As the state capital, Augusta's stock runs from 19th-century construction near downtown and the Kennebec River to mid-century development further from the center, which means the oldest wiring and piping tends to cluster in the historic core. A rewiring project near downtown Augusta usually starts with figuring out what is actually behind the plaster before any quote gets written.
Heating and Cooling in Augusta
About 59 percent of Augusta households heat primarily with fuel oil, roughly 15 percent with utility gas from Summit Natural Gas of Maine, and 11 percent with electricity, per Census estimates. Sitting inland along the Kennebec River gives Augusta colder overnight lows than the coastal towns closer to Portland. Where a gas main already runs down the street, a furnace replacement is often the simplest swap; elsewhere we are just as likely to be quoting a heat pump alongside the existing oil system.

Getting to Know Augusta
Augusta has been Maine's seat of government since 1827, when lawmakers picked it over Portland, Brunswick and Hallowell; the State House architect Charles Bulfinch designed for the new capital opened in 1832 and still anchors the city today. Long before that, Fort Western went up on the Kennebec in 1754, and Benedict Arnold staged his ill-fated 1775 march on Quebec from its riverbank.
The city actually started life under a different name -- it incorporated as Harrington in February 1797, then renamed itself Augusta before the year was out. That is the kind of civic history that comes with being a state capital, and it is part of why so much of the historic core near the river still stands, complete with the wiring and plumbing generations of it have accumulated.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Augusta gets treated. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. 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

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 Augusta
In Augusta, plumbing permits come from the Local Plumbing Inspector at the City of Augusta Bureau of Code Enforcement (16 Cony Street, Augusta, ME 04330, (207) 626-2365). With 18,899 residents, Augusta is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Downtown Augusta sits at the head of tide on the Kennebec River and is vulnerable to spring flooding; the 1987 Maine 'Great Flood' affected the city.
- 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
- 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
How Aces Highlands Handles Furnace Installation in Augusta
- Where Summit Natural Gas of Maine serves the street in Augusta, gas equipment is usually the simplest furnace installation option; elsewhere we quote oil, propane and heat-pump alternatives side by side.
- With 59% of Augusta 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.

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.

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.
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.
