"Y'all, this company was so fast in getting a professional electrician to me, that I know you will be equally pleased. The electrician repaired my outdoor garage outlets, installed new outdoor garage lights, installed a new front entrance light fixture, repaired an outdoor electrical outlet, and indoors, installed a new "tiffany style" 5 globe chandelier, which required assembly that he completed in no time. This technician was an "on time", professional, expert electrician, and I most highly recommend "Livewire Electrical Solutions"."

"If you want a system that will keep everything in your home or business running when the power goes down, Ron and the gang can take care of it. They coordinated the whole operation from a propane tank contract, generator rating, and even surge protection. The installers were very professional and their knowledge is outstanding and earned our respect."

"Very well. I can already tell an improvement in the amount of heat that was being generated inside my home from the ceiling. Three attic fans were installed on the roof to replace three vents that just wasn't getting the job done. Thank you so much."

Generator Install questions, answered by experts

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.

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.

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.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
