"Excellent work, too pricy for simple outlet installation. They wanted $500.00 for a simple outlet in the garage. Very good workmanship on the corrections they did."

"Kane and Scott arrived on the planned day and completed our work in four hours. They were a half hour late from the planned start time, but Kane communicated to me that morning the delayed start time. We had two ceiling fans and two wall sconces, with switches, installed. They worked diligently and carefully, and everything looked great and worked perfectly when they were done. They cleaned up almost everything afterward, but left a lot of dust and some trash behind. We were happy with their work and cheerfully paid the money for which they asked."

"Grand Bay did a phenomenal job installing a new service panel in our home. The crew that they sent out were amazing. Not only did they install a new panel, sub panel and hot tub hook up, They also put in (6) GFI's and ceiling fan. We were so happy with the service we received and would recommend Bay Electric to anyone who needs an electrical job done right, these guys rocked it. Thanks to the entire crew and to Nick who put up with me making change after change. Thanks for putting up with me."

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.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

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.

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.
