"Tri-County Electric Services was able to send a plumber out the next day to provide estimates for a few projects in my home. Chris M. arrived at my home and was professional, knowledgable, straight forward, and friendly. He quoted me fair prices to install a new toilet and new kitchen faucet, both of which I had previously purchased independently and had at home ready to install. I was very happy that he was able to complete the installs that day. He also fixed a minor leak below a bathroom sink. All around a great experience! I will definitely hire them again for future plumbing needs. Chris explained that the company recently added a plumbing division to complement their electric services. Thank you for a job well done!"

"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."

"Mr. Electric provided excellent service for me under difficult circumstances. A building contractor damaged a wire and buried it under 42” of concrete. Ryan Corley, Mr. Electric’s wire detection specialist, was able to locate the wire accurately. Electricians Jeff Shipkosky and Khefren Johnson spent two and a half very long days, in 93-degree heat, digging around the perimeter of my house. Both ends of the damaged wire were eventually located six feet underground, which is considerable deeper than code requires. Justin David, Mr. Electric’s manager, was here working alongside his men and provided all the support possible to them. He maintained full contact and communication with me throughout the entire process. These men, along with a crew of assistants, are a class act company. I was very impressed at the dedication of Mr. Electric and recommend them highly."

Generator Install questions, answered by experts

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

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.
