"We had Tim install a hookup for an external generator into our home electrical system. He was superbly professional in his inspection, quote, and execution processes. It was a pleasure working with this fine young man and watching him in action. He has a passion for the work, and is doing a great job growing his business. He arrived each time as promised, and when there was a delay, I knew about it ahead of time. Quality of the work was first class. Follow through was admirable. Highly recommended."

"Juan was on time and very professional. Did an excellent job adding a sub panel for a generator and even correct a code violation that was found in the main box when he opened it up. The time estimate and price quot where both right on the money. He also did a great clean up job when the work was finished. Would recommend him to anyone needing some electrical work."

"It was pretty rocky. At first. Several appoints made by Tri-State no one ever showed up.Crew showed up to install the Generator before the site survey and did not have necessary equipment or cooperation of Electric or gas company nor call before you dig had been notified. I called Tri-State to warn them the call before dig had never been preformed. They said they'd take care of it, did not happen until right before installation crew came back the second time. The first time they were here they could not have installed the generator even had they had all the parts because none of the utilities had been marked. Finally after about three months the Generac was installed and working. I had several questions that I could never get answered by calling Tri-State. One of the installation team had to come back a couple of weeks later to replace a damaged part and he answered all my questions. The guys who installed the Generac were great, the problem is your guys operation center and call center as far as I can see do not communicate very well. Anyway the generator has worked fine in several power outages this spring. I am happy right now but I live in dread something goes wrong and I have to call Tri-State for help."

"Brian Kozara is a real professional. He spent 2 days evaluating our total electrical systems with pictures of items to be upgraded. He also submitted several quotes for us to select the project we wanted. After selecting our and date to be completed. he showed up on time and completed the project within the parameters he agreed to. He upgraded electrical boxes, major ground Wire, House electrical mast, and GFI outlets. Brian even uses a level to ensure all outlets are installed vertically level. He was very respectful of us and our home. on a scale of 1-5, I would rate him a 10. You can't go wrong with McCormick."

Generator Install FAQs, answered by experts

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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.
