"He installed exhaust fans for two of our bathrooms and a dedicated line for a sump pump that we are getting installed. Service was great and he was really easy to schedule and communicate with. As a newly first time home owner, I appreciated how transparent he was when explain what needed to be done and associated costs. I plan to use him for additional work down the road!"

"Anthony and his team do expert electrical work of all kinds. We are a 145 year old non-profit organization with buildings and grounds, and have contracted with Technician Engineers Group (TEG) on two large projects (and several small ones) over the last 15 years. One project rewired a large 125 year old building listed on the National Register of Historic Places, and one installed an extensive outdoor lighting system. In these two unusual situations TEG worked closely with us to find innovative solutions to our unique needs. We are very pleased with the results, enjoyed their can-do approach, and highly recommend this company for any electrical challenge. We found TEG reliable, honest, on time, and all the work was completed ahead of schedule."

"Awesome! I wanted to do a heavy-up at my new home. I shopped around and got quotes from several companies incl Tim. I chose Paradise because of the price, responsiveness, and professionalism that Tim conducted himself. The job called for significantly more work than expected because of my desire to eventually add a backup generator, Tim made sure that I would not need to reinvent the wheel later and installed the right equipment to meet my future needs. During the course of his work I decided to add several additional outlets and discovered a mis-wired light. He took care of all of the work in short order. Tim is officially my go-to electrician."

"We would definitely contact Mr. Williams for more household projects. He installed a gas cooktop with a downdraft for us. During the install, he discovered that the vent pipe being used by the old downdraft fan was too small. To ensure that we would have a working cooktop that evening, Mr. Williams went to the hardware store for new parts. The price of the project was very reasonable. He also followed COVID-19 safety protocols (mask, gloves, social distancing, staying within the worksite) for the entire project."

Generator Install FAQs, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.
