"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."

"I found him off Craigslist, I didn't find him on Angie's List. He did his thing, he was on time, but I thought he was outrageously expensive for what he did. I didn't know it was Mister Sparky. I went on to Craigslist and they had this one ad that didn't identify who they were. They just said that they were super cheap and the lowest cost etc etc etc. I called them up and I set up an appointment and then Mister Sparky rolls in to the driveway. I had no experience with Mister Sparky. He is the on time electrician. He showed up, he wasn't in the house for more than 50 minutes. All he did really was, he took a wall socket and turned it upside down. I had the polarity upside down, I didn't know it, it was a dimmer switch, a really simple job that he knew and I didn't know it. It was knocking off some wall sockets and then he installed a ceiling light fixture for me that I couldn't do because I just needed three hands and I didn't have them. So, he had the experience. That was all he did. He really just did practically nothing and he charged me $180. It was like $200 an hour. I live in Mount Pleasant. Mount Pleasant is on the Carolina coast here, north of Charleston. It has a lot of people like myself who aren't native to the area. Mount Pleasant in here is perhaps the state's most affluent suburb. It's a very popular place because of its proximity to the downtown of Charleston, with all those attraction for dining etc. The rest of the population kind of lives elsewhere. My experience and I've been here eight years, there is like a Mount Pleasant price and there is a price for rest of the people, wherever they live. That's the problem that you have. You mention that you live in Mount Pleasant and all of a sudden the price is, "How much?" You just have to kind of grin and bear it and shop around. That's just the way it goes around here. They think everybody is rich who lives in here. I pulled them off Craigslist. They didn't identify themselves. They rolled in the driveway and I got a $200 bill, I was a little bit shocked. It was $200 an hour. I was expecting a little over $100 or something, not even that much for what he did. They were on time."

"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."

"R&W Electric was always polite and very professional. It is very nice to see good people with a great work ethic complete a job on task and on budget. We opened up our kitchen and needed to move switch locations, outlet locations, new circuits, ceiling fans and added under cabinet lights. I am glad we hired R&W Electric and would recommend them to anyone."
Removed switch and outlets on this wall
The original kitchen before cabinet demolition. We moved the hood and range outlet and changed the outlet locations for the countertop height outlets.

Generator Install questions, answered by experts

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.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.
