Boiler Installation for Winthrop Homeowners

Winthrop 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.

Winthrop Homes and What They Need
Winthrop's median home dates to 1977, per Census estimates, with about 24 percent of housing built before 1940 and 35 percent before 1960 -- newer than neighboring Augusta or Gardiner, which fits a town that grew as a lakes destination rather than around an old mill or river port. That newer stock still means plenty of 1970s- and '80s-era systems reaching the end of their service life. Water heater repair calls on those original units are common.
Heating and Cooling in Winthrop
About 59 percent of Winthrop households heat mainly with fuel oil, 16 percent with wood, and 12 percent with electricity, and there is no natural gas utility in town. Winthrop's population roughly doubles every summer as seasonal camp owners return to its lakeshores, which drives a predictable spring rush of startup and shutdown plumbing work. For a camp that is slowly becoming a year-round home, a cold-climate heat pump paired with the existing oil or wood setup is a common upgrade path.

Getting to Know Winthrop
Winthrop started out in 1765 as a scattering of lakeside homesteads known informally as "Pondtown," then took its current name at incorporation in 1771, honoring Massachusetts's first colonial governor. For roughly 150 years, the Winthrop Mills Company was one of the country's largest woolen-blanket makers and the town's biggest employer -- a scale of industry that is easy to forget looking at Winthrop's lake-town feel today.
One of the more unusual local landmarks is the 'Ladies Delight Light' on Cobbossee Lake, a small lighthouse built in 1908 that is thought to be the only active inland lighthouse anywhere in Maine. The town has also been growing steadily for over a century, from about 2,088 residents in 1900 to 6,121 at the 2020 count, making it the largest town, as opposed to city, in Kennebec County.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Winthrop gets treated. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. 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.

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.

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!

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!
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.
