Gray Homes and What They Need
Gray's roughly 4,600 homes are younger than much of Cumberland County. Census estimates put the median year built at 1983, and only about one in eight predates 1940. Those older houses cluster around Gray Village and along the old roads out toward Dry Mills. The bigger story is the building wave of the 1970s through the 2000s, when capes, ranches and colonials went up on wooded lots within reach of Turnpike exit 63; about a quarter of homes date from 2000 or later. Roughly one in twenty is a manufactured home, and around 670 units are held for seasonal use, many of them camps on Little Sebago, Crystal and Forest lakes. Houses from the 1980s and 1990s are now reaching the age where original boilers, furnaces and electrical panels with no spare breaker space come due, while a lakeside camp raises questions about insulation and year-round use.
Heating and Cooling in Gray
Heating oil still dominates in Gray. Census estimates show about six in ten occupied homes heat mainly with fuel oil or kerosene, roughly 18 percent with propane, 12 percent with electricity and nearly 8 percent with wood, while utility gas barely registers at under 1 percent. Natural gas mains effectively do not reach the town, so propane is the fallback wherever a gas range or boiler is wanted. Gray is inland and snowy: its climate record shows January averaging in the low 20s Fahrenheit and around 84 inches of snow a year, and the National Weather Service office that forecasts for western Maine and New Hampshire sits on Weather Lane in Gray. For an oil-heated house, a cold-climate heat pump installation can carry most of the winter load while the existing boiler or furnace stays as backup for the coldest nights, and the same equipment handles summer cooling.

Getting to Know Gray
Gray holds one of Maine's most unusual Civil War stories: in 1862, the body of an unknown Confederate soldier was mistakenly shipped to Gray instead of a fallen local Union lieutenant. The women of the town buried the stranger in Gray Village Cemetery and paid for his headstone — marked simply "The Stranger" — and the grave is still tended today. Gray is also home to the Maine Wildlife Park, the state's refuge for animals that cannot return to the wild.
From the village center out to Dry Mills, Gray's homes range from 1800s farmhouses to newer builds off Route 26 — and we service heating, plumbing, and electrical in all of them.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Gray under its own name. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. Earning the next call, not hitting a sales target, is the entire business plan.
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 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.

Codes & Permits for Boiler Repair in Gray
In Gray, plumbing permits come from the Local Plumbing Inspector at the Gray Code Enforcement Office (Henry Pennell Municipal Complex, 24 Main Street, Gray, ME 04039, (207) 657-3339). With 8,269 residents, Gray is required to enforce the Maine Uniform Building and Energy Code (MUBEC). The Gray Water District, established in 1929, draws from a groundwater aquifer and serves roughly 1,100 connections; most of the rest of town relies on private wells.
- The Maine Fuel Board's rules for oil-burning equipment incorporate NFPA 31, the national fire-safety standard covering installation, venting, and chimney-flue sizing for oil-fired appliances like boilers. maine.gov
- Chimneys and vents serving fuel-fired appliances, including hydronic boilers, are governed by NFPA 211, the standard for chimneys, fireplaces, and vents. maine.gov
- State law requires a carbon monoxide detector in each area within or giving access to a bedroom wherever a fuel-burning heating appliance like a boiler serves a covered dwelling. mainelegislature.org
How Aces Highlands Handles Boiler Repair in Gray
- Unitil has mains through parts of Gray, 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.
- With 53% of Gray on heating oil, most boiler repair calls here follow NFPA 31 (oil), NFPA 54/58 (gas/propane) or NFPA 211 (venting), depending on what's already installed.
- 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.

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.

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.
