"Fenix Electric went beyond expectations to hang a flood light camera, replace an outdoor ceiling fan, clear an issue with a gfci circuit, and install automatic light switches for three outdoor lights. His crew was courteous and professional. The work was done expeditiously. His pricing was very reasonable. I recommend Fenix Electric highly!"

"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."

Generator Install FAQs, answered by experts

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two.
