"Brian installed a dedicated circuit in our basement. Brian answered the first time I called. He set up a time to come and review the job. On the day he came, he called to make sure I was at home. He gave me a reasonable price for the job and agreed to do the work the following week. He came exactly when he said he would and performed the work in the time frame he specified. I am extremely pleased with Brian's work and would highly recommend him to anyone who is in need of electrical work."

"They were good. They're price were really good for what we wanted to have done. As far as the work, they came in and they had part of our power back on half way through the day and they had the rest of it on before they left that evening. They had to come back out to test the generator after the propane company came and tested out. They came out and did everything."

"I hired Kloock's Electric to install a television antenna. They came out to do an estimate and we discussed equipment options. I decided on an antenna and amplifier and requested that they install the antenna strapped to a chimney. I received a quote for the work and equipment costs. They ordered the equipment and came out to install it when the equipment arrived. The install went well, and it was apparent that the installer had done this before. They were professional and courteous."

"Dan and his team did a fantastic job. My initial issue ended up being a lot more elaborate than initially anticipated but I was so pleased with their initial work I hired them again to address the larger system issue. I absolutely recommend and will definitely look to hire them again next time I have any electrical problems."

Generator Install questions, answered by experts

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more.
