"We had a great experience working with Byron, during our home renovation. He didn’t just come in and do the electrical work, he took the time to offer thoughtful input that really helped us plan out our lighting and make decisions we’re very happy with. He was knowledgeable, professional, easy to communicate with, and incredibly easy to work with around our renovation schedule. Having someone who was flexible, dependable, and willing to share his expertise made the whole process so much easier. We’re very pleased with the finished work and would absolutely recommend him to anyone looking for a knowledgeable and reliable electrician. We’ll definitely be calling him again for future projects!"

"He received the notice early on Saturday morning and called within an hour. He was at my house to get the estimate done an hour after that. We agreed to have the install done the following Friday to give him time to get the permits done. He and his son we exactly on time and the price was actually lower than I anticipated. A totally professional job. This guy is on my list for my next electrical job."

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. 

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.
