"David did an amazing job. He called me very quickly after I signed up on Angi. He set up a time to do the job within 4 days. He got both jobs done in a very short amount of time. His price was really reasonable. I would not hesitate to hire David again!"

Customers say: Quick response

"Had a Tornado hit my house and ripped out my mains power. Figured I'd upgrade the panel while I was at it and have a generator outlet installed for when I lose power again. Nick was VERY professional - gave me a quote, showed up on time, answered all of my questions, and the price was exactly where I expected it to be. Job was very well done. When the power went back on, my fridge didn't have power. He helped me pull the fridge out to find a GFI outlet, and he helped me reset it. Was really just a huge help! The guy is clearly a hard worker who really knows what he's doing. What I love is that I didn't talk to a sales guy who then sent a couple of kids to do the job. I got a quote, and the guy I spoke to did the work. That's awesome. I can't recommend this guy highly enough! Will reach out for any and all electrical work in the future."

Generator Install questions, answered by experts

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.

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.

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.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

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.
