"Call this electrician! He s worth your call, don t wait for him to call you! He was fair, honest and went above and beyond our expectations. We got two other quotes, one being from another company (Service detectives) who charged us $89 for a QUOTE and then quoted us $19k for everything we wanted done. For the things we needed done (not the whole house but a new meter outside, wiring to the inside, new panel and several outlets rewired) Holtzclaw Electric did for 3 times less than S.D. Just call Brandon. You won t regret it."

"My panel was maxed out with several double taps. I wanted to upgrade as necessary so it would pass inspection before putting my house on the market. A few options were given, with pros and cons of each, and explained as needed. Once a decision was made a contract was signed and the work scheduled. The owner kept in contact with me from beginning to end, even when he needed to reschedule due to unforeseen circumstances. The work was performed efficiently, neatly, and for slightly less than the bid amount."

"As a professional in a similar field, these folks know how to get the job done. Can't say you can hire a company that has the T's crossed and their "i's" dotted more so than these guys. Happy to work with them in the near future!"

Generator Install FAQs, answered by experts

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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. 

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.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
