Whole-Home Generator Installation in Northeastern Connecticut

Northeastern Connecticut loses power — sometimes for days. We install standby generator systems and wire transfer switches so your home or business keeps running when the grid goes down.

Why Windham County Homes Run on Backup Power

Windham County sits in some of the most storm-exposed terrain in Connecticut. Nor'easters, ice storms, and downed lines along rural roads mean multi-day outages are not rare events here — they are a regular part of winter. For homeowners in Putnam, Thompson, Killingly, and the surrounding towns, a whole home standby generator is not a luxury item. It is the difference between three days of frozen pipes and spoiled food and three days of normal life.

 

We have been doing electrical work in this region for over 23 years, starting as Deary Electric. We know how these storms hit and what it costs when the power stays out.

Standby Generators and Transfer Switches — We Install Both

Not every customer is starting from the same place. Some want a permanent whole-home solution. Others already own a portable generator and need the electrical work done safely. We handle both.

 

Whole-home standby generator installation:

 

  • Automatic transfer switch activates within seconds of a utility outage
  • Runs on natural gas or propane — no fuel hauling, no manual startup
  • Generac and Kohler systems available — two of the most trusted names in residential standby power
  • Sized to your actual load, not the most expensive unit on the shelf
  • Permitted and inspected through the proper Connecticut channels

 

Transfer switch wiring for portable generators:

 

  • Manual transfer switch wired to your panel so you can connect your portable generator safely
  • Eliminates the risk of backfeed, which is dangerous to utility workers and illegal without proper isolation
  • Permitted, inspected, and done by licensed electricians

 

If you are not sure which option fits your situation, we will walk you through it.

We Size It for Your Home, Not for the Upsell

One of the most common mistakes in generator installation is oversizing — selling a customer more capacity than they need because larger units carry better margins. We do not work that way. Before recommending a system, we assess your home's actual power requirements: the circuits you need to keep live, your heating system type, whether you have a well pump, and what your budget allows.

 

The result is a generator recommendation that fits your home and your load — and an installation you can trust was done right.

Annual Generator Maintenance Keeps It Ready When You Need It

A standby generator that has not been serviced is a generator you cannot count on. These systems require periodic run testing, oil changes, and inspection of the automatic transfer switch to confirm they will perform when a storm hits. We offer annual generator maintenance for systems we install and for existing units that need a reliable service provider.

 

What our generator maintenance includes:

 

  • Full operational run test under load
  • Oil and filter change
  • Air filter inspection and replacement as needed
  • Transfer switch function check
  • Battery and connections inspection
  • Visual inspection of the enclosure and fuel connections

 

Scheduling annual service is the simplest way to make sure your investment works the first time it is called on.

Licensed Electrical Work, Proper Permits, No Shortcuts

Generator installation is not a DIY project and it is not a job for an unlicensed contractor. Improper transfer switch wiring can backfeed voltage onto utility lines — a serious hazard to line workers and a code violation. Every generator installation we complete is pulled with the proper permits, inspected, and done by our licensed electricians.

 

We serve homeowners and commercial property owners throughout Windham and New London counties, including Putnam, Thompson, Woodstock, Killingly, Plainfield, Norwich, Lisbon, Brooklyn, Willimantic, Ashford, and Eastford.

Frequently Asked Questions

  • What size generator do I need for my home?

    It depends on your load — the circuits and appliances you need to keep running during an outage. A well pump, electric heat, and central air conditioning add up quickly. We assess your home's requirements before recommending a system so you get the right capacity without paying for more than you need.

  • What is the difference between a standby generator and a portable generator?

    A standby generator is permanently installed outside your home, connected to your gas or propane supply, and wired with an automatic transfer switch that activates within seconds of an outage — no action required from you. A portable generator is a lower-cost option you own and fuel manually, but it still requires a properly wired transfer switch to connect to your home's panel safely.

  • Do I need a permit for generator installation in Connecticut?

    Yes. Generator installations in Connecticut require an electrical permit and inspection. This applies to both standby generator installations and transfer switch wiring for portable generators. We handle the permit process and schedule the inspection as part of every installation.

  • Which generator brands do you install?

    We install Generac and Kohler standby generator systems — the two most established brands in the whole-home residential generator market. Both carry strong warranties and have reliable parts and service networks.

  • How often does a standby generator need to be serviced?

    Annual maintenance is the standard recommendation for most residential standby generators. This includes an oil and filter change, run test, transfer switch inspection, and a check of all connections and components. Generators that are not serviced regularly are more likely to fail at startup when you actually need them.
