"Carlos is a PRO. Came out installed a new 200 amp electrical panel, conduit protected 200 amp line in, full bonding and grounding system, as well as ran a line and installed a generator interlock kit. He was thorough in showing me how to operate everything, the craftsmanship of his work was next level, everything up and running in a timely manner, and the cost was great. 10/10 would recommend for any and all electrical needs."

"Excellent and efficient service, on time for appointment, repaired our Generac generator with OEM parts. I've always believed, if you can't explain it simply...you don't understand it well enough. This guy knows his stuff. The technician explained all repairs while making recommendations for future care and preventative maintenance. We understood and felt confident in our maintenance/repair decisions. One stop shop for generator, electrical and heating repair and including oil and propane products. We will be using them going forward for their services. Highly recommended!"

Generator Install FAQs, 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.

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.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two.
