"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 !"

"Earlier today, I searched on Google for an electrician in the Farmington / Unionville CT area and IES came up with high ratings. I quickly called and Greg the owner picked up. He had a pretty packed day but knowing my issue where it impacted my furnace which meant no heat, he understood the urgency and said, he would be willing to stop by in route to his big job today. Within 30 mins or less, he was at my house and resolved my issue quickly. I plan to hire Greg for additional work as adding additional outlets in my garage and helping with a generator hookup. He def earned my business and I highly recommend him. I would like to wrap up this review with - e's a family man, very professional, reputable, and local - happy I came across his company earlier today!"

"Rick, the project manager, was prompt with his response and quote, and checked in with me post installation to ensure satisfaction with the work. The electricians, Drew and Rick, were on time, courteous, and very professional. I had several recessed lights, some switches, and light fixtures installed in a newly renovated space. They were careful to make sure nothing was damaged while they worked and even took their shoes off on the new floor. I would absolutely work with them again in the future."

"They came out in the middle of a storm and promptly hooked the generator to my panel. While I thought I’d be running extension cords to my appliances it turned out that the whole house was up and running. I wish I had done this earlier. I would recommend MGT for any electrical needs. I will surely use them again."

Generator Install FAQs, answered by experts

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

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.
