"Bottom line up front, I was beyond impressed with the work done by Cash Electric. I have a rental property with some electrical gremlins I could not get figured out. After too long, I broke down and looked for an electrician. I was dreading it both mentally and financially. However, from the first interaction through the troubleshooting and to the end of the job I was impressed. Kayleb laid out a straightforward plan for figuring out my problems and made sure I knew what to expect. His crew was able to determine the cause of my issues and give me a prognosis by the end of the day. Kayleb sent over an estimate really quick and was able to get back over to fix my issues within a couple of days. In this economy, and with so many poorly run trade businesses out there, it was a true breath of fresh air to hire Cash Electric. If you have electrical issues, don't like messing with outlet installations or need a generator setup Kayleb and his crew are the only ones you should be looking for."

"Got my ductwork cleaned out and replace 23 outlet covers. All done in record time. Very friendly and professional and explained the whole process as he went and showed me all the junk that came out of my ducts. Cleaned up as he went along and couldn't even tell he had been here except that there's no dust floating around in the air now."

"Sparky Electric was very professional and did a great job with the new outlets and light/vent fan installation. Terry was great to work with and took the time to make sure everything was to my liking and was very capable of the work he performed. I would highly recommend this professional if you are looking for electrical work that has to be done right."

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.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.

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.
