"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."

The installation and hook up was completed in a timely manner. I now have peace of mind knowing that in the event of a power outage I can still provide excellent care to my horses. I will certainly be contacting Apex for my future electrical projects."

"I was so impressed at the excellence and professionalism of this company in doing the projects I needed for my remodel. Iâ m learning that surprises are to be expected when doing so, and for a homeowner, what would be daunting for me, was dealt with easily and knowledgeably for Ryan and Kyle. Ryan came back to address an issue stemming from the quality of the fixtures I chose, and helped me to find an adequate solution, with patience and a great attitude, which spoke volumes to me. I am grateful to find professionals that do quality work, and possess integrity, and I would highly recommend Ryan and his crew."

"I spoke to this company over the phone that told them that I was looking for somebody to trace my household telephone lines. I have a short somewhere and I would like to find somebody that could find it and rewire the telephone system to bypass the short. This company does do that type of work and didn't know of anybody that did."

Generator Install questions, answered by experts

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.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
