Furnace Repair for Falmouth Homeowners

Falmouth sits in Cumberland County, part of the territory Aces Highlands covers out of 508 Riverside St Unit 1 in Portland every week — so a call for furnace repair gets a technician who already knows the local housing and codes, not a first-timer.
A broken furnace in Maine winter is an emergency. Aces Highlands provides fast, accurate furnace repair with honest diagnostics — we fix what actually needs fixing and nothing more.
Common furnace problems include no heat, blower issues, ignition failures, strange noises, short-cycling, and thermostat malfunctions. Our technicians can quickly identify the root cause and get your heat back on.
We repair oil, propane, and natural gas furnaces from all major manufacturers. We carry common parts like ignitors, flame sensors, blower motors, and control boards to complete most repairs in a single visit. Regular furnace maintenance can prevent many of these common issues.
If your furnace is at the end of its life and repair costs do not make sense, we will tell you honestly and help you evaluate replacement options. We never pressure you into a decision.
Why Falmouth Calls Aces Highlands
- We run trucks through Falmouth and the rest of Cumberland County routinely, not occasionally
- Diagnostics come first, upsells do not — the invoice matches the quote
- Booking stays quick because we do not overbook the schedule
- Properly licensed and covered by insurance, and reviewed by real customers on Google
Falmouth Homes and What They Need
Falmouth's housing is younger than most of Greater Portland. Census estimates put the median home here at 1986, and roughly 14 percent of homes have been built since 2010, many of them in newer subdivisions. The older layer is still real: about 14 percent of homes predate 1940 and about four in ten predate 1980, from Falmouth Foreside along Route 88 to West Falmouth Corner and Highland Lake. Around 80 percent of homes are single-family detached houses, and most are owner-occupied. In practice that means two very different kinds of job in one town: a newer colonial with PEX, a mechanical room and room for ductwork, and a Foreside house with copper or galvanized supply lines, tired shutoff valves and pinhole leaks that need tracing behind finished walls.
Heating and Cooling in Falmouth
Falmouth heats with a wider mix than most Maine towns. Census estimates show fuel oil or kerosene in roughly 43 percent of occupied homes, bottled propane in about 21 percent, utility natural gas in about 19 percent, electricity in about 11 percent and wood in about 5 percent. Gas is available because both Unitil and Summit Natural Gas of Maine run mains in town; Summit built into Falmouth, Cumberland and Yarmouth after the three towns chose it through a joint request for proposals, beginning in 2013. Homes near the bay see slightly milder nights than those out toward West Falmouth and Blackstrap, but both need equipment sized for a real Maine January. For many owners the choice is whether to keep an oil or propane boiler as backup or move most of the load to a cold-climate heat pump system, which also adds cooling.

Getting to Know Falmouth
The original town of Falmouth once encompassed what are now Portland, South Portland, Westbrook, and Cape Elizabeth — those communities were all carved out of it over time. Just offshore, Mackworth Island was Governor Percival Baxter's family retreat before he deeded it to the State of Maine in 1943; today it is famous for the "fairy houses" visitors build in its woods and for Baxter's stone-walled memorial to his Irish Setters.
Modern Falmouth is known for well-kept homes with high-end finishes — the kind of properties where clean line-set routing, tidy penetrations, and spotless job sites matter. That is how we work.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Falmouth — not a national franchise. Nobody on our crew works on commission, so there is no incentive to sell you more than the job needs. We show up, fix the actual problem, and let the work speak for itself.
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 Won't Heat? Here's How We Narrow It Down
Furnace calls almost always start the same way — "it's not blowing warm air" — but the actual cause splits into a handful of distinct failure points.

Codes & Permits for Furnace Repair in Falmouth
In Falmouth, plumbing permits come from the Local Plumbing Inspector at the Falmouth Code Enforcement Division (271 Falmouth Road, Falmouth, ME 04105, 207-699-5310). With 12,444 residents, Falmouth is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Falmouth is served by Portland Water District for water but has its own municipal wastewater utility, and by Summit Natural Gas of Maine (not Unitil) for piped natural gas.
- 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
- Oil-fired furnaces fall under the same Maine Fuel Board Oil Burner Technician licensing (Apprentice/Journeyman/Master) as oil boilers. maine.gov
- Installing, repairing, or servicing a propane or natural gas furnace requires a Maine Fuel Board Propane and Natural Gas Technician license, with separate authorizations depending on BTU size and scope of work. mainelegislature.org
How Aces Highlands Handles Furnace Repair in Falmouth
- Where Summit Natural Gas of Maine serves the street in Falmouth, gas equipment is usually the simplest furnace repair option; elsewhere we quote oil, propane and heat-pump alternatives side by side.
- With 43% of Falmouth on heating oil, most furnace repair calls here follow NFPA 31 (oil), NFPA 54/58 (gas/propane) or NFPA 211 (venting), depending on what's already installed.
- Once a furnace 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.

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.

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 Repair FAQs
My furnace stopped working — what should I check first?
Check the thermostat batteries and settings, the furnace power switch (looks like a light switch on or near the unit), the breaker, and the filter — a fully clogged filter can trip the furnace’s safety limit. On oil units, confirm you have fuel and press the reset button only once. If none of that works, call us.
Why does my furnace turn on and off every few minutes?
Short-cycling is most often a clogged filter causing overheating, a dirty flame sensor dropping the flame signal, or an oversized furnace reaching temperature too fast. It wastes fuel and wears components, so it is worth fixing promptly.
How much does furnace repair cost?
Common repairs — flame sensors, ignitors, capacitors — typically run in the low hundreds. Blower motors and control boards cost more. We quote the exact price after diagnosis and before any repair, so there are no surprises on the invoice.
When is a furnace not worth repairing?
When it is past 15 years and facing a major repair like a heat exchanger, blower motor, or control board, replacement usually wins the math — especially counting the fuel savings of a modern high-efficiency unit. A cracked heat exchanger on an older furnace is almost always a replacement, for safety reasons.
Do you repair oil furnaces?
Yes — oil, propane, and natural gas. Our team holds a Maine Master Oil Burner license, so oil-fired equipment is core work for us, not an afterthought.
