"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."

"I have dealt with a lot of contractors. John from Elite Electrical actually shows up (and on time), is respectful, personable, and best of all he knows everything about his trade and did an AMAZING job inspecting and explaining. He was very clear about what needed to happen and pricing for all options. A simple generator outlet turned into a whole panel upgrade, but the original panel was hazardous and he showed me exactly why. He suggested and did not push extra. I would definitely refer and re-hire for more projects."

"The entire project was such a great experience. From the moment I first requested a quote online, Mike has been very responsive (within minutes) and so great to deal with. After talking to a few references provided to me, I decided to proceed with a whole house generator install and new power to my shed out back. They easily worked around my schedule since this is a vacation home. They installed everything in 1.5 days and arrived on time as promised. The entire team was such a pleasure to work with. They prided themselves in making sure they left the place as clean as possible. Don't be swayed by a lack of online reviews. Highly recommend you give them a shot!"

Generator Install questions, answered by experts

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

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