"Chris was a great service man. After a thorough inspection of my power panel, Chris found the problem of power surges and recommended I call ONCOR to fix the service to the house. One phase had burned through the rubber boot. ONCOR promptly came and reconnected the power properly."

"I needed an additional lighting fixture wired in and mounted above our pantry as well as an outdoor outlet in our patio ceiling, Cool Hand crushed it! They were extremely respectful of our home and wore disposable booties over their shoes every time they had to come inside from the attic or backyard. The install was extremely clean & professional, and of course worked flawlessly. Luke was very kind to our curious daughter who didnâ t make his job any easier! We wouldnâ t hesitate to hire them for the next project, they are 1st class."

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. 

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

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

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

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

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
