"Outstanding service. I originally needed an electrician to determine why I lost power to ½ my house. What Jody uncovered was a defective circuit breaker and my main switches overheating and in the process of melting down. He was able to change out the panel and install new breakers immediately. I’m grateful for the prompt response by Gene and the professionalism of Jody and Brian."

"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."

"It went very well.  Tony is very responsive, courteous, and goes out of his way to make things convenient for the customer.  Not only is he very competent and thorough in his work, but he also  did a lot of the leg work, picking things up at the electric supply store, returned a couple things that I had incorrectly purchased there in my own trips prior to hiring him, and even went there on my behalf for a bed lamp that needed a new contact.  He disconnected it, brought it to the store, took a trip back to the store a week later to pick it up, and reinstalled it for me.  Tony could have applied a trip charge for each of the many visits he made to my place but didn't.  He also took the time to explain options, solutions, and even gave me a bit of free schooling in electrical work.  I highly recommend him and his business.

Generator Install questions, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home.
