"After Tropical Storm Helene took down a large tree which took down my Duke Energy power line on side of my home, Chris came and worked 2 full days and got all the electrical service back up and running, They also were sooooo helpful with our 2 year old Generac backup generator which we have had issues with and will soon be returning to address our generator issues. The Field Supervisor, Brandon, went above and beyond by calling Generac and explaining our generator issues. Mister Sparky will from now on be our maintenance contractor after our last one failed us when we really needed them. It was a stressful 8 days without power and using a generator that was leaking oil and not knowing if or when it might blow -up. All the guys at Mister Sparky who came by and helped were professional and truly cared about taking care of us. I will forever Trust and Appreciate Mr Sparky for all my electrical needs."

"I hired GSM Services to replace my A/C unit and furnace with a newer, upgraded system. A few weeks ago Kelly came to my house to give me an estimate for a new heating and air system. He was on time and very professional. He surveyed my existing system, took measurements of my house, and did some calculations to determine exactly what type and capacity system that I would need. He showed and explained to me several options as well as their prices. He wasn’t pushy as he left in order to give me time to review the different options before making my decision. I called the office the next day with my decision and to set up a date and time for installation. Today (May 22) Kyle and Craig showed up on time and were extremely professional as well. They worked from 8:30 to 5:30 completing the replacement of my entire heating/air system. The field team leader also showed up just to ensure that everything was going smoothly. They were very helpful in answering any questions that I had throughput the day and they took the time to explain to me about the new system after installation was complete (I.e. how to operate the new programmable thermostat). Overall, it was a great experience and I will definitely use them again."

"If you need electrical work done, please call J. N. Green Electrical. We started off by calling several companies out to our house to fix what we thought was a minor electrical problem. After three different electricians came out and three different bills, with nothing fixed, we found J.N. Green Electrical on Angie List. We were skeptical at first but said, Let give it a try. Green Electrical was out at our house that same day and was able to fix the problem in no time. They were very professional and charged me less than the other three companies that did not fix the problem. I would definitely recommend them to anyone! They have been our go-to guys ever since!"

Generator Install questions, answered by experts

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

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

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.
