"Overall experience was average. First day of installation was okay until I find out half of the house did not have power. Edgar came back the next day and explained the cause and fixed it with ease. Was getting push back about how everything was installed as it was and there shouldnâ t be any issues, well there was and he graciously came back and fixed the problem. I would definitely use this company in the future."

"Hector was great. When I initially sent out the request for some electrical work to be done, Hector responded with a price range which helped me to make a quicker decision. He came out on a Sunday morning and installed the new outlets and explained exactly what I needed to convert my 2-prong outlets to include a ground. He was fast and efficient. I checked all the outlets he installed and they are working."

Generator Install questions, answered by experts

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.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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. 

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.
