"Stef of Chrome Electrical not only installed 2 car chargers in my driveway, but ran the electrical line from my basement and placed a subpanel in my garage. Stef was very well-informed of not only the requirements and needs for car charging, but what I might need down the road. I could tell that Stef's ideas were thought out for my families' needs. I trust him for any electrical work, in fact, he's also did the rough wiring for my basement remodel."

Welcome to Hanley Electric (formerly) Calvary Electric, LLC! With over 20 years of experience, I'm your go-to guy for all of your electrical needs. My main priority within this business has always been to finish the project to perfection while building lasting customer relationships, and always at an affordable price. I will always treat your home as if it were my own. With me, you will get an upfront and honest answer to any question you have about your project, and I make sure to take the extra time to make sure my clients fully understand what their buying. What I also provide is a $215 diagnostic call before 5pm M-F and $245 after 5pm or Saturday. One hour labor and trip charge included! Give Hanley Electric, LLC, a call today, I look forward to hearing from you!

"I was referred by the hardware store Pro Program for Master Electrician to do some projects we needed accomplished. Skeptical at first; Then, I received a call about 15 minutes later after submitting my proposed project. John, the Master Electrician with Calvary Electric with over 20+ years of experience, said to me, I am extremely busy but I promise, I will work you in within the week. Only two days later, he shows up and is ready to install (2) ceiling fans, switches, run additional electrical lines, etc. John broke everything down, step-by-step for us, what our options are and the exact price it would take to get the projects completed. Then, he noticed I was wearing a Marine Combat-Wounded cover. He said, you are a Vet I see, that is an automatic 10% off I told him he did not need to do that and he said, When I do a job, I look for discounts for the people that request my services, it is the least I can do. I was shocked. We talked a little more and my wife, Rachel and I, made a decision and John got right to work. During the install, he gave continuous updates on where he was and what he was doing. After the project was completed, we did a walk through together (John, Rachel, and Myself) and we were shocked at how outstanding it turned out! He showed us both fan features, how he changed the switches around, so it would be easier for us to control. Then, Joh cleaned up the work areas he had been in. It was cleaner after John left than it was before he arrived. He shook both of our hands, thanked me for my Service, and told us if you have any issues, any at all, contact me immediately and handed me his business card. In summation, I have been around the world while in the Marines. Met, talked and worked with a lot of different and very passionate people, who love their professions. John loves what he does and has that passion to do the very best job he can do, for his customers. John, hands down, is the VERY BEST at what he does, period. My father was in construction for over 30+ years as a General Contractor. So, I have also worked and talked with the civilian side of the Contracting world. Again, you will not find a better Master Electrician than John. I am not into writing things up for people like this however, I wanted people to know that there is a true value, spirit, and faith out there; and it shows in his quality of work and his candor towards his customers. If you want a job done right, the first time, at a reasonable price, contact Calvary Electric @ 810-820-6715 - www.calvaryelectricllc.com You will NOT be disappointed! Respectfully Submitted. Travis and Rachel S. Flushing, MI"

Generator Install questions, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
