"I hired Ozzy’s electrical service to install a 3 phase surge protector on an electrical box for a not-for-profit education center. He provided a quote in writing (via text message) for this and a few other services. Not only did Ozzy (the owner) NOT COMPLETE this service; he told me that I needed an additional service which doubled his original quote. We paid for all of this work including the surge protector even though he did not complete the entire job in one day ( as discussed). It was not until I asked him the location of the surge protector (after he had left the property) that he told me tell that he did not install the surge protector! This was the first thing on my written list for him to complete. He then told me that it would be another $650 to install the surge protector (that I had already paid for)!!!! DO NOT USE OZZY’S ELECTRICAL SERVICE! This is the WORST SERVICE THAT I HAVE EVER ENCOUNTERED WITH A CONTRACTOR FROM ANGI’S LIST! I wish I could give a zero or negative #!"

"SSGE acted like a teenager wrt aftersale service. The first time I called SSGE was when then was an alarm on the system, ( a year after install) and they refused service!!! The reason per SSGE was that there was dispute during install. During the sales process, SSGE had told me that HOA approval was NOT needed. Right after installation, the HOA wanted to remove the generator, and it took me 2 weeks to sort out the issue. I paid SSGE the second half of the payment in full only after the dispute with HOA was settled in about 2 weeks.Is that a good enogh reason to not provide service?? I had to call Generac's head-quarters and they helped me trouble shoot the alarm on my system."

Generator Install questions, answered by experts

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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.
