Ag-Pro Power Division specializes in the sale, service and installation of Generac home automated standby generator systems. We provide preventative maintenance programs for residential generators regardless of where you purchased the unit and also sell portable generators made by Generac. Our products can be purchased at any of Ag-Pro's locations in Ohio & Kentucky.

"We had purchased a home that include a 13.5kw Generac whole house standby generator that was not actually installed but just sitting behind the house unused. I contacted JD Power Systems to see if they could test and verify that the generator worked and if so then hook it up. They sent out a technician free of charge that was able to get the generator up and running and was able to verify that it was basically a brand new never used generator. They gave me a fair quote of what it would cost to pull proper permits, move the generator to the correct location to be within city codes and get everything hooked up with a full house auto transfer switch. It took about 5 hours total to get everything done but i'm very happy with the results. The entire crew was friendly and courteous and I appreciated that they didn't mind me hovering around them as I watch them do the install."

Generator Install questions, answered by experts

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. 

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

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. 

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.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.
