"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."

"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."

"Terrific job. Mock Electric installed a power line on an independent circuit for a new electric fireplace located about 100 feet away from our fuse box. They were on time and did the work in a thorough and efficient manner and on budget. Thank you for this recommendation!"

"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

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

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

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

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

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.
