"Working with Elite was incredible. A company I had used for years had refused to do the work. I found Elite on Angie's List and saw their fantastic ratings and reviews. They worked with me on a timeframe, arrived when promised, and dealt with less than ideal conditions that come from a house that has multiple cats. The owner came himself and spent the time necessary to find the problem and then corrected it in short order. The price was very grease. Elite has a new customer for life. Excellent in every way."

"He was a professional which is what i wanted for my home. I just thought the service provided was expensive. 175 dollars for and outlet seemed high for me. But i wouldn't hire anyone else except for a certified electrician for my home so it was worth the expensives. Safety and quality cost money."

Generator Install FAQs, answered by experts

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 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.

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.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
