"Quinn was professional and courteous. In addition to the EV charger installation, he also installed 2 new circuits with breakers and new conduit. All the work looked amazing and he and his associate cleaned up everything when they were done. Couldn’t have been happier with the work done. Would highly recommend Quality Electric."

Customers say: True professional

"Highly recommend this electrician! He installed my chandelier at a very fair price and went above and beyond by coming up with a smarter wiring solution that avoided cutting into the drywall. That saved me a lot of extra repair and restoration work. Professional, thoughtful, and efficient—exactly the kind of service you hope for."

Generator Install questions, answered by experts

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.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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. 

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

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
