"Great sales team......gave me all of the information requested. The installation went without any issues. Once installed they went over the instructions. Since September 2020, the generator kicked on for 13 hours in December and a couple of times for three hours each. Well worth every penny!"

"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."

"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

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. 

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.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

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.
