New furnace and boiler installation for Orono and the Greater Bangor area, sized to the house and installed with combustion safety checks before we call the job finished.
We at One Stop Home Repair have installed heating systems across the Greater Bangor area since 1980, according to the company’s own history. Maine’s heating season runs long, so a new furnace or boiler here has to perform for months at a time, not just handle the occasional cold snap.
Because our crew includes licensed electricians alongside heating technicians, a new system’s power and control wiring, along with any venting fan it needs, gets installed by the same team doing the mechanical work, rather than scheduled as a separate visit. Much of the housing stock in and around Orono predates modern insulation standards, and an older home’s heat loss profile is part of what a proper load calculation accounts for, rather than sizing a replacement to match whatever the previous system happened to be rated for.
Every heating system installation is backed by our Best Price Guarantee and covered by insurance. Combustion equipment installed incorrectly is a safety issue, not just a comfort one, so we check venting, combustion air supply, and carbon monoxide safety on every install before considering the job done.
A furnace or boiler is usually worth replacing rather than repairing again once it is old enough that parts are getting harder to source, once repairs are becoming frequent, or once a homeowner is paying more to keep an inefficient system running than a new one would cost to operate. We size every replacement with a load calculation rather than matching the old system’s rated output, since a furnace that was oversized the first time around usually cycles too often and wears out faster than it should.
New gas furnaces are required to meet a minimum efficiency standard set by the Department of Energy, which finalized a 95 percent AFUE minimum for most gas furnaces in December 2023, phasing in over the following years. That standard affects venting, since a high-efficiency furnace vents differently than an older, lower-efficiency unit, and getting the venting right the first time avoids a callback later.
Fuel type is the other major variable. Homes on oil heat face different cost and delivery considerations than homes on natural gas or propane, and a homeowner replacing an aging oil furnace sometimes finds that switching fuel types, or moving to a heat pump for part of the heating load, changes the economics of the whole project. We walk through the real tradeoffs for your specific home and fuel access rather than defaulting to a like-for-like replacement.
If a heat pump might fit your home better than a combustion system, see our heat pump installation page. For a system that just needs a repair rather than replacement, our heating system repair page covers that work, and our heating and cooling maintenance service can extend the life of a system that still has years left in it. Homeowners weighing efficiency upgrades alongside a new heating system can also see our green energy services.

A system nearing the end of its rated service life, needing frequent repairs, or costing noticeably more to run each winter than it used to is usually a candidate for replacement rather than another repair. We look at the specific repair history and the system’s age before recommending replacement, rather than assuming age alone is the deciding factor.
The right size comes from a load calculation based on the home’s insulation, window area, and layout, not from matching the old system’s rated output, since the old system may have been oversized to begin with. An oversized furnace or boiler cycles too often, wastes fuel, and wears out faster than a properly sized one.
Switching from oil to gas, propane, or a heat pump is worth considering at replacement time, since that is when the cost of a fuel switch is smallest compared to changing fuel types outside of a planned replacement. We can walk through the real cost and availability tradeoffs for your specific home rather than pushing one fuel type over another.
Most heating system replacements in Maine require a local permit, and requirements can vary by town within the Greater Bangor area. We handle the permit process as part of the installation so you do not have to track down the requirements yourself.
Most furnace and boiler replacements are completed in one day, though a job that also involves venting changes, ductwork modifications, or new electrical circuits can take longer. We give you a specific timeline based on your system and your home during the quote.
A properly installed new system is generally safer, since it comes with modern safety controls and gets a full combustion and venting check at installation, something an aging system may not have had in years. We check carbon monoxide safety and combustion venting on every installation before considering the job complete.

I’ve relied on Howard and the folks at One Stop for decades at three different locations in Orono. That probably says it all in terms of customer satisfaction.

I have zero plumbing experience and needed a bunch of work done to a shower in my home. Upon first search on Google I found One Stop Home Repair.

The service I got was prompt and they are very nice people to deal with. My heat pump went within a day, they put a new one in for me. Their plumber Eric did a super job.

The December 18 storm caused a 3000 pound branch to fall on two cars and the garage as well as tearing shingles from the house. I called them at 8 AM and they had a crew there at 10 AM.
