"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 !"

"Ted and Robert arrived, got right t to it and within a few hours we had 2 ceiling fans installed, one which had no existing light so it was a more involved project. They were professional and stuck to their original quote! To say we are impressed is an understatement. We strongly recommend using Connole Electric."

"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!"

"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

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.
