"Mike re-wired my basement outlets at my apartment. He figured out that all of them were wired incorrectly. Not only did he restore power to my basement outlets, he prevented an electrical fire from the previous incorrect wiring. He also installed a new bathroom fan/light combo, with Bluetooth speaker capabilities and multiple led light colors. He was efficient, fairly priced and honest. Highly recommend! Thank you again Mike!"

"The owner Chris was fantastic and answered my calls and questions in record time, came out quickly for an estimate. Once great price was agreed on, he arrived on time with his staff to get started. This is an old house which I'm sure gave them some challenges, but they efficiently went about their business and answered all my questions, got the job done, left everything clean and made sure I was satisfied. Kudos to Will and Aimee! I would highly recommend and will definitely use Calkins Electric again for my next project."

"He is extremely attentive to your needs . What he says will happen , does! He keeps all appointments and thoroughly explains what he plans to do. He is one of the most reliable, ethical , conscience businessman I have ever dealt with. I have recommended him to friends . He actually went out of his way to help Ill friends deal with their generator problems even though he had not installed it. He made arrangements for someone to fix the generator when he was not able. Highly recommended !"

"Kevin has been doing electrical work for us for about a decade, first upgrading the electrical ststem in our 1920s bungalow in Willimantic, and then coming out numerous times to update various elements in our historic home in Chaplin. He's great to work with, no- nonsense, thoughtful about creating safe solutions for our older house, including a generator installation. A nice person and a true professional."

FAQs for generator install projects in Lisbon, CT

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:

  • Portable generators with 1kW–7.5kW capacity: $500–$2,000

  • Partial generators with 9kW–20kW capacity: $2,000–$6,300

  • Whole-house generators with 22kW–48kW: $5,000–$18,000

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:

  • Experience frequent or prolonged power outages

  • Work from home

  • Store a lot of cold food

  • Have a sump pump

  • Have a pump for well water

  • Use electronic medical devices

  • Live in a climate requiring heating or cooling
