Furnace Maintenance for Eliot Homeowners

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

Eliot Homes and What They Need
Eliot's median home was built in 1979, with about a quarter of housing predating 1940, reflecting a town that grew substantially from roughly 2,500 residents in 1950 to over 6,700 by 2020. That range of construction eras means service calls here run from vintage farmhouse wiring to routine work on newer subdivisions.
Heating and Cooling in Eliot
About 62 percent of Eliot households heat mainly with fuel oil, with bottled or tank propane at 21 percent and electricity at 7 percent; there is no confirmed natural gas utility reaching Eliot itself, even though neighboring Kittery has gas service. A heat pump paired with the existing oil system is a common upgrade here.

Getting to Know Eliot
Eliot incorporated as its own town on March 1, 1810, and today borders three New Hampshire communities -- Dover, Portsmouth and Newington -- across the Piscataqua River, along with South Berwick and York on the Maine side. The town is also home to Green Acre, a historic Bahá'í school property.
Eliot's population has grown steadily from around 1,650 residents in 1810 to over 6,700 by 2020, with most of that growth landing in the second half of the 20th century. The town is now extending municipal water and sewer service along the Route 236 corridor under a tax-increment financing district.
Local & Independent — Not a Franchise
Aces Highlands answers to Eliot homeowners directly, not a franchise office somewhere else in the country. 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

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.

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.
