Furnace Maintenance for Auburn Homeowners

Need furnace maintenance in Auburn? Aces Highlands runs out of 508 Riverside St Unit 1 in Portland and covers Androscoggin 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.
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.

- We run trucks through Auburn and the rest of Androscoggin County routinely, not occasionally

Auburn Homes and What They Need
Auburn's median home was built in 1954, with 38 percent of housing dating before 1940 and 57 percent before 1960 -- slightly older on average than Lewiston's stock, concentrated in the shoe- and mill-era neighborhoods that grew up after the city's 1848 rail connection went in. That vintage of housing is exactly where rewiring work tends to turn up knob-and-tube remnants and undersized panels.
Heating and Cooling in Auburn
About 51 percent of Auburn households heat mainly with fuel oil, 22 percent with utility gas, and 11 percent with electricity, per Census estimates -- though Auburn, like Lewiston, is not in Summit Natural Gas of Maine's published service area, so that utility-gas figure likely reflects an older local distribution setup. Either way, plenty of Auburn's oil-heated homes are good candidates for adding a heat pump alongside the existing system.

Getting to Know Auburn
Auburn once had one of the largest shoe industries in the country -- by 1917 the city's factories were turning out roughly 75 percent of the world's supply of white canvas shoes, before the industry faded after World War II. That manufacturing boom is a big part of why Auburn's older neighborhoods look the way they do today.
Auburn sits across the Androscoggin River from Lewiston, and the two cities share more than a border: they draw water together through the Auburn Water District, and the Little Androscoggin River cuts through Auburn as well. Auburn also runs its own municipal Electrical Department, which both maintains the city's traffic signals and streetlights and handles the city's electrical code inspections.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Auburn — not a national franchise. 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 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 Auburn
In Auburn, plumbing permits come from the Local Plumbing Inspector at the Planning, Permitting & Code, City of Auburn (60 Court Street, Auburn, ME 04210 (Auburn City Hall), (207) 333-6600). With 24,061 residents, Auburn is required to enforce the Maine Uniform Building and Energy Code (MUBEC). Auburn grew as a mill town after the railroad arrived in 1848, powered by falls on the Androscoggin and Little Androscoggin Rivers; its shoe-manufacturing industry once produced a majority of the world's white canvas shoes (1917).
- 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 Maintenance in Auburn
- With 51% of Auburn on heating oil, most furnace maintenance calls here follow NFPA 31 (oil), NFPA 54/58 (gas/propane) or NFPA 211 (venting), depending on what's already installed.
- 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.

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!

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.

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 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.
