"I went with a local company that has been around for decades because I want an installer who will be here when I need service or follow-up in the future. Hegge Electric installed panels, subcontracted roofing preparation and completed all approvals in a timely manner with excellent workmanship. They completely refinished interior walls where drywall had to be removed for conduit, and you can't tell it was ever done! The system works perfectly and we are enjoying our green energy from a local company with a long reputation."

"There was an unexpected charge for punching a hole in the drywall and installing a five foot copper wire from nearest light switch box to feed to each of the 4 lights. There was a second upcharge to convert from 6 inch to the modern 4 inch diameter LED lights (expected). Unfortunately one of the workers started his work early failing to understand that 4 inch was to be installed, he cut a hole for 6 inch. Now the drywall has to be patched to close the hole. They were punctual, fast & cleaned up. There is more work to do, ie convert existing 6 inch incandescent down lights on the lower two floors, those total to about 15. This work was done on the third level. I would re-hire if these things were addressed."

"We live in the Joshua Tree area and had a Kohler generator installed in 2021. Unfortunately, by 2025, it had failed. A local electrical contractor inspected it but couldn’t repair the issue, so we turned to the expert—Pete Poillon. I’m incredibly glad we did. Pete promptly diagnosed the problem: the controller board needed replacing. Kohler confirmed the part was covered under warranty, but required us to contact their Rancho Cucamonga service location. That’s when things got costly. They charged $3.95 per mile plus $185 per hour for travel time, bringing the total service estimate to a staggering $1,500–$1,800. In hindsight, choosing a Kohler generator was a major misstep. If we had gone with Generac, warranty service would have been handled locally by Poillon Electric at no extra charge. Lesson learned—we won’t make that mistake"

Generator Install questions, answered by experts

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.
