Furnace Maintenance for Westbrook Homeowners

Westbrook homeowners call Aces Highlands for furnace maintenance because we are close by, based at 508 Riverside St Unit 1 in Portland, and out on Cumberland County roads every day — we know this area's housing, weather and permit process cold.
Regular furnace maintenance is the best way to prevent unexpected breakdowns and keep your heating bills in check. Aces Highlands provides thorough annual tune-ups that keep your furnace running safely and efficiently.
Our furnace maintenance service includes filter replacement, burner cleaning and inspection, heat exchanger inspection, safety control testing, blower motor lubrication, thermostat calibration, and a complete combustion analysis.
A cracked heat exchanger is one of the most serious furnace safety issues — it can allow carbon monoxide to enter your living space. Our maintenance inspection includes a careful check for this and all other safety concerns. We also recommend having your boiler maintained at the same time if your home has both systems.
Schedule your furnace tune-up in early fall before the heating season. Catching small issues early prevents mid-winter breakdowns and keeps your system running at peak efficiency all season long. Contact us to book your annual tune-up.

Westbrook Homes and What They Need
Westbrook's housing splits cleanly into two eras. Census estimates put the median home at 1975: about a quarter of units date from before 1940, the old mill-town core along the Presumpscot, while roughly a quarter were built since 2000 as the city grew faster than any other in Maine between 2010 and 2020. Fewer than half of homes are single detached houses, about a fifth of units are in buildings with five or more apartments, and about 6 percent are mobile homes, a higher share than most nearby towns. Neighborhoods such as Cumberland Mills, Frenchtown and Deer Hill carry older two- and multi-family houses, while newer apartments and subdivisions fill in toward Prides Corner and the edges of town. That older half often has aging drain stacks and supply piping, and clearing old drain lines is a routine part of keeping it working.
Heating and Cooling in Westbrook
Oil still heats about half of Westbrook: census estimates show roughly 49 percent of occupied homes on fuel oil or kerosene, about 19 percent on utility gas, about 17 percent on electricity and about 11 percent on bottled propane. Unitil's Northern Utilities serves the city, so gas is an option on many streets near downtown and the main roads. Westbrook sits a few miles inland of the harbor, so winter nights run a touch colder than on the Portland peninsula. Older homes here were built around oil-fired boilers or furnaces and many have no central cooling at all. A common upgrade is adding central air conditioning through a heat pump, which also takes a large share of the heating load off the oil burner.

Getting to Know Westbrook
In January 2019, a giant spinning disk of ice roughly 300 feet across formed on the Presumpscot River in downtown Westbrook and made headlines around the world — news crews from as far away as Europe and Japan covered it, and it has reappeared in later winters. Westbrook's identity as a mill town goes back much further: the paper mill S.D. Warren bought in 1854 still operates today under Sappi.
Generations of mill workers built Westbrook's neighborhoods, which is why so many local homes are sturdy older houses with aging mechanicals. Panel upgrades, boiler swaps, and heat pump retrofits in that housing stock are some of our most common Westbrook calls.
Local & Independent — Not a Franchise
Aces Highlands is independently owned and based in greater Portland, with no franchise territory map dictating how Westbrook gets treated. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. 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

Annual Furnace Maintenance: The Real Checklist
Furnace maintenance is the most commonly skipped HVAC service, largely because a furnace can run for years with no visible sign it's overdue — until the one cold morning it doesn't.

Codes & Permits for Furnace Maintenance in Westbrook
In Westbrook, plumbing permits come from the Local Plumbing Inspector at the City of Westbrook Code Enforcement Department (2 York Street, Westbrook, ME 04092, 207-854-0638). With 20,400 residents, Westbrook is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Housing stock skews older: 36.7% of housing units were built before 1960 (24.8% before 1940), with a median year-built of 1975 — more legacy plumbing/heating systems than the county average.
- Maine's adopted 2021 International Mechanical Code (part of MUBEC) sets installation, clearance, and venting requirements for furnaces in municipalities that enforce the code. maine.gov
- 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
How Aces Highlands Handles Furnace Maintenance in Westbrook
- Northern Utilities, Inc. d/b/a Unitil has mains through parts of Westbrook, 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 49% of Westbrook 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 furnace maintenance 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.

Furnace Maintenance FAQs
How often should a furnace be serviced?
Once a year — ideally in late summer or early fall before the heating season. Oil furnaces especially should never skip a year, since soot buildup and nozzle wear steadily degrade efficiency and reliability.
How often should I change my furnace filter?
Check monthly during heating season and replace every 1–3 months depending on filter type, pets, and dust. A clogged filter is the single most common cause of furnace short-cycling and overheat shutdowns we see.
How much does a furnace tune-up cost?
Typically $150–$400 depending on fuel type, with oil furnaces toward the top because the service includes a new nozzle, oil filter, and full soot cleaning. We quote up front and run seasonal specials on our coupons page.
What happens if I skip furnace maintenance?
Efficiency drops as dirt accumulates, small failures go unnoticed until they strand you without heat, manufacturer warranty coverage can lapse, and safety issues — cracked heat exchangers, venting problems, CO — go undetected. Skipping maintenance does not save money; it defers it with interest.
Will you inspect for carbon monoxide?
Yes. Every tune-up includes a heat exchanger inspection and a combustion analysis that measures CO directly. We also recommend every home with fuel-burning equipment keep working CO detectors on each level.
