Need boiler repair in South Portland? Aces Highlands runs out of 508 Riverside St Unit 1 in Portland and covers Cumberland County routinely, which means a technician who already understands the area's homes and permit process shows up, not a stranger learning it on the job.

When your boiler breaks down in the middle of a Maine winter, you need it fixed fast and fixed right. Aces Highlands provides expert boiler diagnostics and repair with a focus on safety and accuracy.

Common boiler issues include no heat, low pressure, strange noises, leaking, short-cycling, and thermostat problems. Our technicians diagnose the root cause accurately so you are not paying for repeat visits or unnecessary parts. If your boiler leak has caused water damage, our leak repair team can help address that as well.

We repair oil, propane, and natural gas boilers from all major manufacturers. Whether it is a faulty circulator pump, a failed zone valve, a cracked heat exchanger, or a control board issue, we have the experience to handle it.

Safety is always our first priority with boiler repairs. We test all safety controls, check for proper combustion, and verify carbon monoxide levels before clearing a system for operation. If your boiler is beyond repair, we offer professional boiler replacement with honest guidance on the best option for your home.

South Portland Homes and What They Need

South Portland's housing is younger than Portland's but still old: census estimates put the median home at 1968, about a quarter of units date from before 1940, and roughly six in ten were built before 1980. A noticeable bump in the 1940s reflects the wartime shipyard years already noted on this page. About half of homes are single detached houses and about a quarter of units are in buildings of five or more apartments, and close to six in ten households own. The older grid neighborhoods such as Ferry Village, Knightville and Meetinghouse Hill hold modest capes and two-story houses on small lots, with later subdivisions filling in the rest of the city. Houses from the 1940s and 1950s can still have small 60- or 100-amp services, ungrounded circuits and galvanized supply lines, so plumbing work in a South Portland cape often turns up aging pipe once walls are opened.

Heating and Cooling in South Portland

Heating fuel in South Portland is close to a three-way split. Census estimates show about 38 percent of occupied homes on fuel oil or kerosene, about 34 percent on utility gas and about 18 percent on electricity, with bottled propane near 5 percent. Unitil's Northern Utilities serves the city, so gas is available on many streets but not all. The whole city sits on Casco Bay and the Fore River, and the Jetport runway is inside city limits, so the official Portland weather record is effectively local: January lows average in the mid-teens and nights at or below zero come about ten times a winter. Wind off the water drives heat loss in older, loosely built houses. Many owners of oil-fired homes are adding ductless mini-splits in South Portland to cut oil use while keeping the existing system for the coldest stretches.

Getting to Know South Portland

During World War II, South Portland's two shipyards built 266 cargo ships in just four years — 236 American Liberty ships plus 30 "Ocean" class vessels for Britain — with a workforce of roughly 30,000 that included thousands of women welders. The Liberty Ship Memorial near Bug Light Park marks the spot today.

That wartime boom is why South Portland has so much solid mid-century housing — homes built for shipyard workers and their families. Those same houses are now prime candidates for modern heat pumps, updated panels, and new water heaters, and we work in them constantly.

Local & Independent — Not a Franchise

We are an independent, Portland-based company, not a franchise chain routing your South Portland job to a call center. 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 Boiler Works

  1. Burner — ignites fuel to heat the exchanger
  2. Heat exchanger — heats the water circulating in the loop
  3. Circulator pump — pushes hot water through the loop
  4. Expansion tank — absorbs pressure as water heats and expands
  5. Baseboard loop — hot water out, cooler water returns

Boiler Troubleshooting: Reading the Symptoms

A boiler that won't fire and a boiler that fires but doesn't heat the house are different problems with different urgency. Here's how to tell them apart before we arrive.

How Aces Highlands Handles Boiler Repair in South Portland

  • Northern Utilities, d/b/a Unitil has mains through parts of South Portland, so a gas-fired swap is on the table wherever a line already reaches the street; off that grid the choice is oil, propane or a heat pump.
  • About 38% of South Portland 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.
  • Once a boiler repair 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.

    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.

  • John Walton

    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.

  • Adam Ayan

    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 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.

Boiler Repair FAQs

My boiler has no heat — what should I check before calling?

Check the thermostat is calling for heat, the emergency switch (usually a red switch at the top of the basement stairs) was not flipped off, the breaker is on, and — for oil systems — that you have fuel in the tank. Press the red reset button on an oil burner no more than once. If none of that restores heat, call us rather than repeatedly hitting reset, which can flood the chamber with oil.

Why is my boiler making a banging or rumbling noise?

That kettling sound usually means scale buildup on the heat exchanger or air trapped in the system — both fixable, and both worth addressing promptly since kettling stresses the boiler and wastes fuel.

Why does my boiler keep losing pressure?

A leak somewhere in the system loop, a failing expansion tank, or a relief valve that is weeping. Small leaks are not always visible — they can hide in a slab or wall — and continually topping off with fresh water accelerates corrosion, so it is worth diagnosing rather than living with.

Is a leaking boiler an emergency?

Treat it as one. A minor fitting drip is often a quick fix, but a leak from the boiler block itself means the heat exchanger has failed. Either way, shut off the water feed if the leak is significant and call — water damage compounds by the hour.

How much does boiler repair cost?

Common repairs like circulator pumps, zone valves, and ignition components typically run from a couple hundred dollars up to around a thousand depending on the part. We diagnose first, quote the exact repair before doing it, and never invoice you for guesswork parts.
