"I got quotes from 4 other companies. Worley's was the only one who looked for and found the water shut off valve behind a shelving unit in my garage.They were very detail oriented. The man who found the turn off valve asked about my water heater. Where was it. He decided that the updated code required a tank to be installed above the water heater. When they did the job of replacing the water line in my front yard, they also put box with a turn off valve in the ground in front of my home. They were very neat and cleaned up after the job was done. All of the men who came here to work were very polite, nice guys."

"Jay did an outstanding job! He showed up right on time and was very professional. He installed a new GFCI breaker and ran a new outlet about 50ft through my crawl space to allow me to run my dehumidifier on a dedicated source. His work was fast and of very professional quality. He will be my first call the next time I need any electrical work done!"

"I hired Quantum because I needed to have a 30amp plug and transfer breaker circuit installed for my generator to connect to my house. Quantum also added a 30 amp service to my garage for my camper hook up. Mike made sure the project was done to code and looks great also. He was very professional and completed the job in the time promised. Both projects were very fair priced. I have had contractors and neighbors ask for his information after seeing the great work on my projects. I highly recommend Quantum and will use them again for sure."

Generator Install FAQs, answered by experts

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.

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. 

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. 

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
