Boiler Installation for Gardiner Homeowners
High-Efficiency Systems
Proper Sizing & Design
Clean Copper Piping
Gardiner homeowners call Aces Highlands for boiler 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.
Aces Highlands installs high-efficiency boiler systems designed to keep your home warm through the toughest Maine winters. Every installation is properly sized, cleanly piped, and thoroughly tested before we leave.
We install oil, propane, and natural gas boilers from trusted manufacturers including Viessmann, Buderus, and Weil-McLain. Our installations feature clean copper piping, properly insulated lines, and professional workmanship that speaks for itself.
Every boiler installation starts with a heat loss calculation to determine the right size system for your home. An oversized boiler wastes fuel and short-cycles, while an undersized system cannot keep up in cold weather. We get the sizing right. Pair your new boiler with a radiant floor heating system for the ultimate in comfort.
We handle complete system installations including boiler placement, piping, zone controls, expansion tanks, and all necessary safety devices. Our work meets or exceeds all applicable codes and manufacturer specifications. Ask about our financing plans for new boiler installations.

Gardiner Homes and What They Need
Gardiner's median home was built in 1944, with 47 percent of housing dating before 1940 and two-thirds before 1960 -- among the oldest housing stock of any Kennebec County town Aces serves. Much of it sits inside the National Register-listed downtown historic district, about 7 acres and 47 buildings along Water Street, Cobbossee Stream and the Kennebec riverbank. Exterior work in that district can draw added review, so a heat pump installation near downtown often starts with a conversation about where the outdoor unit can actually go.
Heating and Cooling in Gardiner
About 58 percent of Gardiner households heat mainly with fuel oil, with utility gas from Summit Natural Gas of Maine at 14 percent and bottled or tank propane at 12 percent, per Census estimates. That leaves a healthy share of oil-heated homes as candidates for a heat pump add-on, and gas-served streets as candidates for a straightforward furnace replacement when the old system finally gives out.
Getting to Know Gardiner
Gardiner traces back to 1754, when Boston physician and drug merchant Dr. Silvester Gardiner began developing more than 100,000 acres at the head of navigation on the Kennebec River. The city later built an economy around exporting river ice, packed in sawdust and shipped as far as the tropics, alongside a paper industry that boomed from the 1860s into the 1920s.
Gardiner's entire downtown was added to the National Register of Historic Places in 1980, and the poet Edwin Arlington Robinson, who won three Pulitzer Prizes, grew up here and is still remembered locally. That historic downtown, with its ice-and-paper-era brick blocks, is a big part of why Gardiner's housing stock runs as old as it does.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Gardiner — not a national franchise. Technicians are not on commission, so the recommendation you get is the one your house actually needs. That is how we keep customers calling back, one honest job at a time.
How a Boiler Works
- Burner — ignites fuel to heat the exchanger
- Heat exchanger — heats the water circulating in the loop
- Circulator pump — pushes hot water through the loop
- Expansion tank — absorbs pressure as water heats and expands
- Baseboard loop — hot water out, cooler water returns

Boiler Installation: Sizing, Piping & the Details That Matter
A boiler replacement is one of the few HVAC jobs where reusing the existing piping layout without checking it can quietly undercut the new equipment's performance.

How Aces Highlands Handles Boiler Installation in Gardiner
- Where Summit Natural Gas of Maine serves the street in Gardiner, gas equipment is usually the simplest boiler installation option; elsewhere we quote oil, propane and heat-pump alternatives side by side.
- About 58% of Gardiner 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.
- We don't close out a boiler 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.

Boiler Installation FAQs
How long does a boiler last in Maine?
A well-maintained cast-iron boiler commonly runs 20–30 years; high-efficiency condensing boilers typically last 15–20. Annual maintenance is the biggest factor — a neglected boiler gives up years early, a serviced one keeps going.
How much does boiler replacement cost?
Most full residential replacements in Southern Maine land between $7,000 and $12,000 installed, depending on fuel type, efficiency class, and the piping and venting work involved. We provide a firm written quote before any work begins, and financing is available.
How long will I be without heat during the swap?
Most replacements are completed in one to two days, and we plan the changeover so your home is without heat for the shortest window possible — usually just part of one working day.
Should I convert from oil to propane or natural gas?
It depends on fuel availability at your address, your current equipment’s age, and long-term fuel pricing. Conversions unlock quiet, compact high-efficiency boilers, but they carry added venting and fuel-line costs. We install oil, propane, and gas systems, so our recommendation is not biased toward any one answer.
What boiler brands do you install?
We install trusted manufacturers including Viessmann, Buderus, and Weil-McLain, and we match the brand and model to your system design rather than pushing a single house brand.
