"My son had a whole house generator installed by this company. Very pleased. I had a whole house generator installed also. Had a water softener installed too. They did a great job. Very friendly and skilled workers. Came on time and finished on time. I couldn't be happier. Fair price, great products and great service. Could not ask for more"

"Chris and his assistant did an excellent job of explaining the situation and options for repairing or replacing our hot water heater. In the end we chose to replace it and they were able to secure a new unit and install it within 3 hours. Would definitely recommend Chris and Tri-County Services and will use them again if another situation arises."

"Services were solid but prices are ridiculous with this company. It was a $20 part that took less than 30 minutes to install. They charged me $337.00. I should have researched before agreeing to the service. Way better values out there in NE Ohio."

"The job was done very well. Our lower level was a major problem and it turned out that our fuse box was in serious trouble. The team explained the problem and quickly fixed the lower level issues and fuse box. The bathroom fan needed parts in order for the installation to be completed to my satisfaction, the technician showed me exactly what to order and I have, he is coming back out to install them. We are pleased with the work, how easily it is to make an appointment and they were on time, in addition I received an email with the a photo of the technician and name therefore I knew ahead who was coming to my house."

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. 

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
