Here at Everly Electrical Contracting we strive for excellence and take extreme pride in our work. We are not your typical service provider we are not going to come in and take advantage of our customers like most electricians do, we don't believe in lying to or cheating our customers by making them think services are required when they are not necessary.

"Hired Anthony Everly for multiple jobs related to my new home purchase. Communication was terrible, very unreliable, and I am not sure how but he billed my credit card directly at times without my approval. I have not been able to get him to provide justifications for the expenses/direct charges. I will definitively not use him again and am contemplating options to make sure the charges stop, perhaps even get refunded."

"They charged me almost $500 for a job that took them less than 30 minutes. They're explanation of the job was not detailed when I made my initial phone call and they charge $75 to drive there $150 to tell you what is wrong and $250 to do the job. There is no hourly rate, but they say they have one. They don't tell you that each job has its own price."

Generator Install questions, answered by experts

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. 

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.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
