"We hired Bob to install an electrical outlet on a separate line for our electric outdoor grill and a 100 cfm exhaust fan our bathroom. No moisture appears on our bathroom mirror and surrounding area. They kept all appointments on time and gave us exactly what we asked for. We would hire Bob again. His men were very courteous."

"Hewson Electric could not have done better with our new detached garage! They even installed a generator on my new structure and it couldn’t look more professional. So happy with them, I will never call another contractor for electrical work!!!"

"Aubrey is great. We set an appointment which he was prompt for. He estimated the time which he was also right on the money, and the work was done neat, clean, and everything tested perfectly. This is the second time I have had him do some work for me and will call him for anything else electrical that I have."

Generator Install questions, answered by experts

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.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.
