"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."

"The owner, Dave Fisher, recently installed a Home Guardian Backup Generator for my home. He did a great job of helping design a system that meets my needs. The installation works perfectly and looks great. Electrical and Lift Services did an A+ job of resolving all issues associated with the install. I highly recommend this dealer for a professional generator install."

"They remodeled our bathroom. Reconfigured the shower stall and put in tile. They put in vinyl plank flooring and a new commode. They installed gutters on the house and installed a new front door. They have a great work ethic. Easy to get along with when we changed our minds a time or two and then added some things we thought of later. They responded quickly to any issues we were concerned about. We highly recommend DLT Contracting and will be contacting them again for any future projects."

Generator Install questions, answered by experts

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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.

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.
