"This was an usual project. It was redoing a mini bar. Hard to find a contractor that would do it or had the time. Homepro was great lead by project manager Shir Hadad. Jumped right in there and took it on and got the job done. Really appreciate their professionalism."

"I live in the valley six months and East Coast 6 months. I have used Hegge three times. In 2005, Jose Santos replace 2 kitchen fluorescents with 6 recessed cans and then put in 4 additional recessed cans with its own dimmer in eating area where there had been only a fan with a bad light. In 2011, Francisco Montano put in an additional recessed can in a dimly lit closet. On 1/18/18, Francisco repaired loose wiring leading to a frequently tripping GFCI and corrected a blown circuit with a GFCI. These guys are expert, quick, neat, friendly, and prices are so reasonable for what they do. They are so neat that when they are done, you can't tell that what was new was not there before. Hegge goes out of its way to accommodate your schedule. I wish I had a Hegge for everything, not just electrical. The price quoted was just for the last service"

Generator Install FAQs, answered by experts

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.
