"We brought Gridwise in for electrical work connected to a solar wiring project. I was a little on edge going in because our last contractor experience was? not great. Stas was the first person we talked to and he set the tone: clear scope, what?s included, and what might change if the panel had surprises. That alone made it feel more predictable. On install day, Enrique ran the job and the crew was steady and respectful in the house. When something small came up, they didn?t force one path?they gave a couple options and explained the pros/cons in a way I could actually follow. The finished work looks intentional (not rushed), and we passed inspection without any back-and-forth. Overall it was just? smooth. I?d use them again."

"Just got a hot tub delivered and needed the electrical run to it. Mark and crew came out and installed a 50-amp GFCI breaker and ran conduit along the side of the house to a disconnect near the tub. Looked way cleaner than I expected. Passed inspection and we were soaking that weekend."

"I had 2 ceiling fan/lights installed in the bedrooms. Installation included 2 new circular circuit boxes in each bedroom ceiling. In addition, I replaced the kitchen ceiling light with an LED fixture. The 2 workers were very polite and professional and worked quickly and efficiently, in addition to being respectful of my personal belongings."

"We needed to install an EV charger receptacle quite far from the electrical panel. Chris suggested leading individual wires through a conduit instead of simply using Romex, saying that heat characteristics are better. He also wanted to know what EV charger we were getting and asked for documentation. We also discussed other aspects of the work. His genuine interest and attention to detail made us choose him. At the end, we were impressed with the quality of the work he delivered and how easy it was to communicate with him. He charged about the average price for this work but delivered more than many other electricians would do."

"Edgar is very detailed, respectful, professional with very good customer service! He showed up on time and completed the electric panel change sooner than expected! I have already referred him to my cross the street neighbor, Diane. Hopefully she will reach out soon for an estimate to change out her electrical panel too. Thank you ð ð"

"The installers were very sweet and professional. But I donâ t think I was made completely aware of how the exterior installation would look. The last 4 or 5 feet of the white pipeline are not covered and it looks unfinished and messy."

Generator Install questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
