"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."

"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 FAQs, answered by experts

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.
