"He is extremely attentive to your needs . What he says will happen , does! He keeps all appointments and thoroughly explains what he plans to do. He is one of the most reliable, ethical , conscience businessman I have ever dealt with. I have recommended him to friends . He actually went out of his way to help Ill friends deal with their generator problems even though he had not installed it. He made arrangements for someone to fix the generator when he was not able. Highly recommended !"

"Jeremy is an incredibly efficient, kind, and hugely capable electrician. He spent the day at our house with his helpers installing a generator, and he dealt with every single problem that came up cheerfully and efficiently. I would highly recommend him to anyone for any size job. He makes himself available for any problems and is just overall a terrific person, who is extremely good at what does."

"Great service and Mark was professional at his work and explaining the problem. It wasn't the fan in the master bedroom that went bad, and he suspected the circuit GFI was tripped. We spent a little time to look for the failed GFI and was able to locate it in an odd place. The diagnostic price was a little expensive though."

"The electrician Kyle was professional , honest and affordable. He was punctual and courteous. I hired him for the wiring and panel upgrade but I requested he change my six GFCI outlets and check the older outlets. He checked the outlets that I was worried about -they were good. He did need to replace a different inside outlet and 2 of the 4 outside outlets. He was kind and explained why they needed to be replaced. One just was no longer working. The other 2 were not up to code actually were a fire hazard. I am female senior citizen grateful I hired Elevate Electric."

"We've worked with Mike on three major kitchen/bathroom remodels now, and he has always managed the projects expertly, ensuring that everything was done to an extremely high standard. What's more, he and his co-workers are a pleasure to have around the house. Renovations are inherently stressful, but Mike takes care of everything for you. My only reservation in recommending him and his company is that he'll get so booked up he won't be available to help on our future projects! Highly recommend."

Generator Install questions, answered by experts

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.

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. 

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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.

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.
