"Not good, tech said the generator was out of code due to location, did not perform services. He told me office would be in touch they scheduled a quote bid for 9/23/2020 many weeks after tech was here, so after bid it will be one to two weeks before relocation of generator and service. Process is taking way to long I was willing to advance pay if they brought materials on 9/23 and complete proper install. It’s Hurricane season. They also billed me for the maintenance which he could not do because he said it was out of. Code."

"I would highly recommend this contractor. He was hired to install a home generator. He was professional and completed the job in an acceptable time. He came to my home & advised me what kind of generator I needed, gave me a quote (which I thought was very reasonable), ordered it & had it delivered to my home. Once delivered, he & his crew installed & tested it to make sure it operated correctly. They cleaned up after themselves, took away all debris. Everything was accomplished very quickly & the pro gave me good instructions on how to use it along with the manufacturer’s guidelines. Thank you, Dreamworld and thank you, Angi for recommending this pro."

"Mr. Wadford was and is very responsive to any query or request. He was always on time as was the installer. He was very patient and thorough in explaining the system operation and Bluetooth software. He insured that I understood everything and answered any and all questions. I have only had the system for a short time but it is performing perfectly. This project is to replace n old system. This new system cost $1500 less than the 20 year old system it replaced. The Wadford Water Works provides a quality system as well as quick, efficient and professional installation. I am thoroughly pleased with my decision with my choice to do business with Mr. Wadford."

"Very well. The Mister Sparky electrician who did our estimate also did the repair work on our home at our request. He did an excellent estimate of the work we needed done, did the work very professionally and personably, and finished the job within the estimate. This involved pulling new cable through an underground conduit and routing part of the same cable through a Charleston crawl space - it was no simple job. If I was rating this electrician I would rate him "A" across the board, but the company gets a "C" for Responsiveness because of its extremely poor office support, i.e., its answering service. Similarly, the electrician would have been rated "A" for Professionalism but the company gets a "B" rating for Professionalism for its office support. I told the company's manager and the electrician who made the repairs that its answering service is in need of substantial improvement at the time of the job."

"The company does great work. I am please with the work. They worked fast and were very friendly. They will be installing more lights for me in the near future. The lights that I bought for him to install in the kitchen doesn’t light up the kitchen enough, so since I liked the design of light so much the owner suggested that i place the same exact light in another area of the kitchen. Great idea. He was hundreds dollars cheaper than other quotes that I received. They do wonderful work. I have already recommended him to my sister that needs electrical work."

Generator Install questions, 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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
