"Scott and Doug were prompt, professional, personable and outstanding in getting the job done. The fans had to be assembled during installation and some of the fixtures were from China so a good electrician was required. They respected my home and I paid the amount quoted. They are focused and do not waste time; they wiped their finger prints off my chrome fixtures!! I will be hiring them again in the next few weeks."

"The electrician was prompt, courteous, and skillful. My only reservation was cost. However I did not try to negotiate it when the estimate was given . I provided all of the material to run a line from an attic fan and switch that I had installed, and a dedicated generator circuit breaker with an outside outlet. The cost of $485 included the permit fees. The work took a little over 2 hours."

"Review: I recently had an EV charger installed at my home, and I couldn’t be more pleased with the service. Shield electric was professional, knowledgeable, and efficient throughout the entire process. The installation was completed flawlessly, and everything was left clean and organized. Our electrician took the time to explain the setup and ensured everything was working perfectly before leaving. I highly recommend him for anyone in need of electrical work, especially EV charger installations!"

"He received the notice early on Saturday morning and called within an hour. He was at my house to get the estimate done an hour after that. We agreed to have the install done the following Friday to give him time to get the permits done. He and his son we exactly on time and the price was actually lower than I anticipated. A totally professional job. This guy is on my list for my next electrical job."

Generator Install questions, answered by experts

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

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.
