Power outages in Windham County are not the kind that last a couple of hours while you wait out a thunderstorm. Ice storms, nor'easters and downed lines on rural roads can knock out the grid for days. When that happens, losing power does not just mean sitting in the dark. For most homes in this part of Vermont, it means losing the well pump, so there is no water. It means losing the boiler, so the pipes are at risk. It means losing the refrigerator, the sump pump, whatever medical equipment someone in the house depends on. A generator is not a luxury item here. It is a practical response to a real and recurring problem.

Windham County Generators installs and services whole-home standby generators and automatic transfer switches for homes across Windham County, and can also set up portable generator interlock systems for homeowners who prefer that route. Every job starts with a real conversation about what the house actually needs. That means looking at the loads, the fuel situation, the budget and whether a standby unit or a properly wired portable setup is the right answer. The goal is not to sell the most expensive piece of equipment. It is to make sure the customer ends up with something that works when the grid goes down.

Homeowners shopping for a generator usually arrive with a list of questions, and the right answers depend on specifics that vary from house to house. How big does the generator need to be? What fuel should it run on? What happens to the transfer switch if the power comes back in the middle of the night? Does the propane tank need to be a certain size? What does annual maintenance actually involve? These are all fair questions, and they deserve straight answers.

The FAQ section below covers what most Windham County homeowners ask before they make a decision. If your situation raises something not covered here, the best next step is a call so the specifics of your home can be factored in.

How do you figure out what size generator my home needs?
Sizing starts with a load list specific to your house. That means identifying which circuits you want to power, then calculating the running and starting draw of each one. A well pump motor, for example, pulls two to three times its running wattage when it starts. Adding those numbers up correctly is what prevents an undersized unit from tripping on overload the first time the furnace and pump start together.
Do I need a whole-home standby generator, or will a portable unit do the job?
It depends on your priorities and budget. A whole-home standby unit starts automatically and runs on a fixed fuel supply, covering your full electrical load without any action on your part. A portable generator wired through an interlock and inlet can cover essential circuits at a lower upfront cost but requires you to be home to start it and manage fuel. If the interlock and portable setup genuinely fits your situation, that is what we will recommend.
What is a portable generator interlock, and how does it work?
An interlock is a mechanical device installed on your main electrical panel that prevents the utility feed and the generator inlet from being on at the same time. This stops backfeed from reaching the utility lines, which protects utility workers and your equipment. Your portable generator plugs into a dedicated inlet on the outside of the house, and you manually select which breakers to run.
What fuel options are available for a standby generator in Vermont?
Most whole-home standby generators in Windham County run on propane, since natural gas lines are not available in much of the county. Propane is stored on-site in a dedicated tank. The tank needs to be sized to carry the generator through an extended outage, which we factor into the planning conversation before any equipment is ordered.
How big a propane tank do I need for a standby generator?
Tank size depends on how much fuel the generator burns per hour at typical load and how long you want the supply to last without a refill. A generator running continuously through a multi-day storm can empty a standard residential tank quickly. We calculate the run time based on the generator's consumption rate and recommend a tank size that matches the outage durations this region actually sees.
What does an automatic transfer switch do?
An automatic transfer switch monitors the utility feed. When it detects that power has been lost, it signals the generator to start and then switches your home's circuits over to generator power, typically within seconds. When utility power returns, it switches back and shuts the generator down. You do not need to be home or do anything manually for this to happen.
Will the generator run my well pump and boiler at the same time?
That depends on the generator being sized to handle both loads simultaneously. A well pump motor has a high starting surge, and so does some boiler ignition equipment. If both happen to start at the same moment, a generator that was only sized for running watts can trip. Getting the sizing right from the beginning is what prevents this from being a problem during an actual outage.
How long does installation typically take?
A straightforward whole-home standby installation generally takes one to two days once equipment and fuel supply are in place. Jobs that involve longer electrical runs or panel work can take longer, and adding a new propane tank to the scope adds time as well. We will walk through the scope of your specific job before scheduling so there are no surprises about what is involved.
What does an annual maintenance visit involve?
A standard maintenance visit covers oil and filter changes, battery and spark plug checks, and a full exercise run under load, plus coolant level checks and transfer switch contact inspection on larger liquid-cooled units. Generators that sit unused between outages can develop fuel and battery issues that only show up when the power goes out, which is the worst time to find a problem.
My generator is running but something seems off. Can you diagnose it?
Yes. Generator repair and diagnostics are part of what we do. Battery failure and carburetor problems on air-cooled units come up often, as do transfer switch faults. Bringing the symptoms, error codes if your unit displays them, and the service history to the call helps narrow things down faster. Some issues can be identified over the phone; others require an on-site visit.
Does the generator need to be tested regularly even if the power has not gone out?
Most standby generators are set to run a short automatic exercise cycle once a week, usually under no load or light load. That cycle keeps the engine lubricated and the battery charged, but it does not replicate real operating conditions. An annual service visit that includes a loaded test run gives a more complete picture of whether the unit will perform when it is actually needed.
What permits are required for generator installation in Vermont?
Generator installations typically involve an electrical permit and an inspection by the local electrical inspector. If a new propane tank is being installed, that work has its own requirements. We handle the electrical side of the permitting process. Your propane supplier handles the tank and fuel line permitting. We will walk you through what applies to your specific installation before work begins.

Choosing a generator setup is not a decision you want to rush, and it is not one you want to get wrong. An undersized unit trips on overload the first time the furnace and well pump start up together. An oversized unit costs more to buy and more to fuel, and it runs wet if it is never loaded properly. A transfer switch wired without attention to local utility requirements can create a dangerous backfeed condition. These are not theoretical problems. They are the kinds of things that happen when the equipment selection and installation process is treated as a formality rather than the actual work.

The sizing process at Windham County Generators starts with a load list built around your actual house. Which circuits do you need to keep running? What is the starting draw of your well pump motor? What does your boiler control board require? Those numbers drive the generator selection, not a rule of thumb. If the numbers say a 14-kilowatt unit handles your essential loads comfortably, that is what gets recommended. If they say you need 22 kilowatts to run the whole house without shedding loads, that is what gets recommended instead.

Fuel supply is part of the same conversation. A standby generator that runs on propane needs a tank sized to carry it through an extended outage, not just a standard residential tank that empties after 48 hours. Getting the tank sizing right upfront avoids a situation where the generator shuts down because the tank ran dry during a four-day storm.

Annual maintenance matters too. Generators that sit for months between outages need to be exercised, have their oil and filters changed on a schedule and have their transfer switch contacts inspected. A unit that has not been properly serviced is not a unit you can count on.
