Authorized Generac generator installation across Orono and the Greater Bangor area to keep your home powered through outages.
One Stop Home Repair has served Maine homeowners from Orono since 1980, growing into a full-service contractor with five specialized divisions. We are an authorized Generac dealer and install stand by generators for homes and businesses. Our crews work across Bangor, Brewer, Old Town, Hampden, Hermon, and out to Belfast, Bucksport, and Ellsworth. We know the rural lots, long driveways, and older homes where outages hit hardest.
In much of Maine, the heating system is the first to stop when the power fails. Boilers need electricity for their burners and circulators, as do pellet stoves and heat pumps. That is why we size every generator installation around the loads a household cannot lose in January.
We start with a property assessment and load calculation to determine your power needs, generator location, and fuel requirements. Then we select the right Generac model, prepare the pad, and set the generator in place.
We install the automatic transfer switch, complete the electrical and fuel connections, and configure the system. We then test the generator under load and verify automatic transfer when utility power fails and returns. Finally, we set the exercise schedule and controller and walk you through the operation.
A standby generator in Maine has to start in deep cold, and Bangor sees plenty of it. According to the National Weather Service’s 2023 Annual Climate Review, Bangor had only 10 nights below zero that year, which was half of normal, and the city’s wind chill still reached minus 47 degrees in February.
Cold hits a generator at its weakest points: the battery loses cranking power and engine oil thickens. Generac recommends a battery warmer and an oil filter warmer where temperatures regularly fall below 32 degrees. A breather warmer is advised where sub-zero temperatures or heavy icing are routine. We include these accessories in the installation plan.
Placement matters as much. Generac’s clearance guidance calls for 5 feet from any operable window, door, or vent, 5 feet of open space above, and 3 feet at the front and both ends. Installation under a wooden deck is not allowed. We also keep units clear of roof edges where sliding snow lands and plan a path you can shovel in February.
Transfer switch connections and gas piping are licensed trade work in Maine, so we complete them with properly licensed tradespeople and pull the permits your town requires.
Every home generator installation we complete in Maine is built around the house, not a package size. A home with a heat pump and electric range may need whole-house coverage. A camp may only need the boiler, well pump, and a few circuits.
Schedule a Generac Site Assessment
We offer Generac financing options so backup power does not have to wait until you have saved the full project cost. Generac says its financing program covers both the generator equipment and installation.
The lender sets rates, terms, and approval, all subject to credit approval. We can review available options when we quote your installation.
Homeowners in Orono, Bangor, Brewer, Hampden, and towns across the Penobscot region rely on our authorized Generac technicians, certified electricians, and 24/7 emergency line, all from one local company here since 1980. Book your site assessment and head into winter with emergency backup power that starts on its own.
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.

Whole-house coverage fits homes where every circuit should work during an outage. Essential-circuit coverage keeps heat, water, refrigeration, and some lighting running. We decide by measuring your actual electrical loads, listing what your household cannot lose in a Maine winter, and checking your panel and service size. A load management module can let a smaller Generac unit cover more of the house by shedding lower-priority loads during peak demand.
Natural gas is the most convenient fuel when a gas line already serves your street because it supplies the generator continuously with no tank to refill. Homes without gas service, including much of rural Maine, typically run a Generac on propane from a tank sized for a multi-day outage. We weigh expected run time, your existing propane setup, and available space, then coordinate licensed gas piping as part of the installation.
Yes, a properly sized Generac standby generator can run an oil boiler, propane furnace, or heat pump through an outage. Oil and propane systems draw modest power for the burner, circulators, and controls. Heat pumps need more capacity, and their startup demand must be part of the load calculation. If your boiler or furnace needs work first, our heating system repair team can handle it before the generator goes in.
The timeline depends mostly on equipment availability, your town’s permit and inspection schedule, and the fuel connection. We start with a site assessment and load calculation. Then we provide a written quote and clear schedule before beginning any work. After installation, we test the system under load and walk you through it. Booking before late fall gives you the best chance of being ready before winter storms arrive.
Yes, we install Generac standby generators at camps, lake houses, and seasonal homes where backup power keeps the heat, well pump, and freezer running while you are away. These properties often suit an essential circuit system fueled by propane. Generac’s Mobile Link monitoring on compatible models lets you check the generator’s status remotely. We plan winter access so the unit can be serviced when the camp road is snowed in.
A Generac generator needs scheduled maintenance including oil and filter changes, battery testing, air filter and spark plug checks, and a review of its exercise and fault history. Generac sets maintenance intervals by model and run hours so a long outage can bring the next service due sooner. Our Generac service team handles upkeep and repairs any unit that fails to start or transfer power.
