Sizing honestly, not upselling
The easiest way to sell a generator is to frighten someone into the largest unit on the price list. We would rather run the numbers. Most Stonington households do not need to run central air, an electric range and a hot tub during an outage — they need heat, well or boiler pump, refrigeration, some lighting, internet and the ability to charge devices. That is a much smaller and cheaper machine.
We build a circuit list with you, calculate the actual starting and running loads, and then recommend a unit that carries it with sensible headroom. If you genuinely want whole-house coverage including air conditioning, we will size for it and tell you what it costs — but you will be choosing that, not being steered into it.
Automatic versus manual, and where the real cost sits
An automatic transfer switch senses the outage, starts the generator, transfers the load, and reverses all of it when utility power returns — usually within thirty seconds and with nobody home. A manual switch with an inlet box costs a fraction as much but needs a portable generator, fuel on hand, and somebody physically present to start it.
The right choice depends on whether the property is occupied full-time, whether anyone in the house depends on powered medical equipment, and whether you have a well pump or a sump that cannot go unattended. We will lay out both properly. Note that the generator itself, the gas line and the pad are often larger line items than the electrical work — we will tell you which parts of the quote are ours and which are the plumber's or the supplier's.
Testing and the years afterwards
A generator that has never been tested under load is a decoration. On commissioning we run it against real load, verify the transfer and re-transfer timing, check the frequency and voltage under step loads, and walk you through the exercise schedule and what its status lights mean.
After that, an annual check keeps it honest — battery, oil, filters, transfer switch contacts, and a load test. Most generator failures in New London County happen because a unit sat untested for four years and then met a February ice storm. We can look after that for you or show you what to check yourself.
Generator Installation in Stonington — what to expect locally
The properties we work on in Stonington range from period homes with original wiring in the walls to newer builds where everything is accessible and the job is straightforward. That range is why we quote after looking rather than over the phone — the same nominal job can be a two-hour visit or a full day depending entirely on what is behind the plaster.

Stonington customers on this work
They fixed a mess left by a handyman — junction boxes buried in the wall with no cover. Found four of them. Terrifying but sorted.
Warehouse LED retrofit. They ran the numbers on the payback honestly, did it over a weekend, and our lighting bill dropped exactly like they said.
Office fit-out — new sub panel, data runs, LED retrofit across the suite. They worked evenings so the staff never lost a day. Invoice matched the quote exactly.
Generator Installation in Stonington — common questions
What size generator do I need for my Stonington home?
It depends entirely on which circuits you want running. An essential-circuits setup covering heat, water, refrigeration, lighting and internet is typically a modest unit. Whole-house coverage including central air needs considerably more. We build the circuit list and run the load calculation before recommending anything — call (833) 652-8933.
How much does whole house generator installation cost in Stonington?
The electrical portion — transfer switch, sub panel, wiring, permit, commissioning — is quotable flat once we have seen your panel and the proposed generator location. The generator unit itself and the gas supply are separate line items. We will break the quote out clearly so you can see exactly what each part costs.
Do you install Generac generators in Stonington?
Yes, Generac is the most common standby brand we install in Stonington, along with Kohler and Briggs & Stratton. We are happy to install a unit you have already bought, or to source one as part of the project.
How long does the installation take?
The electrical side of an essential-circuits install is usually a single day. A whole-panel automatic transfer switch is one to two days. If a gas line needs running or a concrete pad pouring, that adds calendar time but not necessarily our days on site.
Does a generator need a permit in Connecticut?
Yes — the transfer switch and generator circuit require an electrical permit and inspection, and the gas connection is separately permitted. We handle the electrical permit and inspection within our flat price.
