"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."

"The installation today by Cory could not have gone better. He called before arrival, gave me a fair estimate before starting work, completed the work in no time flat (less than 2 hours) and was a complete pleasure to work with. Very knowledgeable electrician who I easily conferred with about other electrical issues and I would gladly work with Cory in the future. Highly recommended!"

Generator Install FAQs, answered by experts

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. 

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.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

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.
