"CD Electric was fantastic. They added electrical outlets to the interior and exterior of my home and installed an exterior light. Chase was very thorough with the estimate he provided me and completed the job in the time he said it would take. I would definitely hire them again for any future jobs and I highly recommend them to anyone else."

Customers say: Quick response

"Tom from Synergy did the bid for under cabinet lighting install, however sent someone else to do the job. Originally discussed with Tom that he would use a regular converter box inside the cabinet and place a dimmer switch on the wall, but the other guy he sent wasn't aware of this and placed the dimmer converter in the cabinet. This has resulted in us having to use the dimmer switch inside the cabinet instead of on a wall switch -- not what I requested. Also, I discussed with Tom installing an additional outlet in our kitchen during the bid process. After he left I noticed he did not include that on the written bid. The guy he sent didn't know about it either. The outlet was installed however. Overall, I was charged $95 additional over the bid and didn't get exactly what I wanted in regard to the dimmer switch for under cabinet lighting. Both electricians were very nice and professional, but there was definitely a communication problem in regard to the installation of the under cabinet lighting. Perhaps I should have clarified the issue more strongly, or perhaps I didn't understand. Either way, I'm happy with the lighting overall, but not 100%."

"I could not be happier with the final product! The first pic is the old bathroom from the 60s when the house was built. The rest are the final rebuild and it looks great. I would highly recommend VMK Remodeling for any project that you might have. I am also going to get a bid on redoing the deck on the back of the house as Vince's company does decks as well! Thanks to his great crew as well, great people to work with."

"Things went great with them and we are still using them. As soon as our bar is installed, they are going to finish up the electrical work. They were fast, reliable and really nice people. They were also on time. We got bids and they had the lowest bid."

Generator Install questions, answered by experts

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.

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.

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.

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.

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.
