"Sergio and his assistant installed an EV charger at my place, and they did an amazing job. I’m so glad I hired them. Their price was reasonable compared to other contractors. I highly recommend them and would definitely use their company again for any future jobs."

"Highly Recommended! We have hired Zero Electric to do several jobs at our apartment complex including installing a generator, EV chargers, new panel, and even installing recessed lighting in the units. They handled all aspects of the projects and had top notch communication throughout. The team has always been quick and professional. We will continue using Zero Electric for our electrical needs."

"The electricians installed two outlets and one LED light fixture in a very professional manner. They provided good advice and suggested that I consider rejunvenating my electrical panel as my home is now 26 years old without pressuring me to have it done immediately. I will definitely consider Trout Electric when I decide to have it done."

"They are knowledgeable and installed the car charging station in my garage. I had compared with other companies who seemed to be cutting corners, and I felt McKee was doing things the right way so I chose them. His communication was good, he was on time, and followed through on what he said he would do. Good, clean, and professional. I intend to have him back out for my next electrical project."

Generator Install questions, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.
