"We had Henderson Electric hook up the electrical for our new hot tub. They installed the proper breakers, ran conduit/wiring through the attic, to the outside wall, underground to a post, then mounted a switch panel and completed wiring to the hot tub. Can't say enough good things about our experience. Excellent quality of work overall. Very clean and complete professional work. Also very good communication and follow up, which, unfortunately, is not all that common these days. Classic example of doing it right or don't do it, which we really appreciated. We also appreciated the knowledge and expertise as we knew what we wanted done, but not necessarily the best way to accomplish what we needed. They helped us explore and weigh out several options for different ways to do the job, and explained pros and cons of each option. Gave us an estimate the next day and got us on the schedule right away. We had contacted other contractors/electricians and got a few other estimates, some more expensive, some less, but none of them gave us the level of personal service and professionalism like Henderson's. Would absolutely recommend Henderson's to anyone looking to get any home electrical work done."

"Near impossible to get ahold of them, I understand being business, but then there is blatant ignoring. Even after planning another job. I cant access my Internet cable as its now stuck under a outside wire tube. Needing to call my Internet provider to get it moved."

Generator Install questions, answered by experts

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.

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.

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. 

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.
