"I had an excellent experience working with Andy and Chris for our electrical needs. From the very beginning, they were professional, knowledgeable, and incredibly responsive. They arrived promptly, assessed the situation quickly, and explained everything clearly before getting started. The job they completed was absolutely phenomenal. Their attention to detail, workmanship, and commitment to doing things the right way truly stood out. You can tell they take pride in their work. Not only was the quality outstanding, but they also worked efficiently and completed everything much faster than expected without cutting any corners. It’s rare to find contractors who combine skill, professionalism, and speed the way Andy and Chris do. I highly recommend them to anyone looking for reliable, high-quality electrical work. I will definitely be calling them again for future projects!"

Generator Install FAQs, 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.

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. 

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.

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