"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."

"Apex installed a Whole Farm generator for my horse farm. They were very professional when they came to determine the size generator I needed and the quote was quite reasonable. 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."

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

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
