"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"

"We needed an interlock put in for a generator. Phoenix was quick to respond. Had the job done in less the a week. Professional, knowledgeable, honest and dependable. He went through all the breakers to check wattage to make sure we could run what we needed in case we loose power. I would highly recommend him. He is our new electrician and already have a project in mind."

Generator Install FAQs, answered by experts

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.
