"40 X 32ft shop. 27 conduit drops to include two 220 drops for Welder and Mini Split Technicians were very courteous, knowledgeable and professional. They answered all my questions thoroughly. After the install, they briefed on the electrical panel. Organized to perfection. I would not hesitate to hire this business again. Highly recommended. Thanks again to Mike and Chadwick, you made the experience positive. Brandon"

"I would still like to hire CP, Hill, Davis or Circle S. but I don't know what to do from here. I would give them a better score If I could see their work on my home. I only marked ( would not hire them ) because there is no in-between. I have been trying to get some one to install a Transfer Switch for my new generator, I called ( Hill ) with no response then Home Advisor gave them my number and still no response. I called ( CP Electric ) with no response then Home Advisor suggested them And gave me their number. So what's the point of me calling them again. I first hire another Electrician (Circle S) he came out and gave me a bid but never showed up to do the job. I then called him three times and he never called back. I then called a fourth electrician (Davis Electric) 2 times and he never called back. This might be considered a small job but I think they should at least call you back and tell you that they can't do it for what ever reason. That's called doing good business. No disrespect to any of these businesses I'm just getting pretty frustrated trying to get something done. This is the same thing that happened when I tried to hire a roofer with Home Advisor , I still have a bad roof jack that is probably leaking water into my rafters causing damage. I have cash money and no one wants it. Is this Texas wide or just a Gilmer Problem. Never had these issue where I used to live. Home Advisor does not work at least not here."

"After being in the dark numerous times, I wanted a whole house generator. I contacted CD Electric (Clint) to come assess my situation. He recommended the right size for us! It was installed quickly and correctly! I have recommended him to friends who have also had generators installed too."

Generator Install FAQs, answered by experts

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.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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.

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. 

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
