"I am very pleased with the service I received from Mr. Electric of Gastonia. Daniel and Matt explained all the issues with the old panel and I decided to have it replaced along with a whole house serge protector. While they were here they kept me informed of what they were doing and how the job was progressing and when they were done they cleaned up. Daniel and Matt were always on time and they called ahead when they were on their way. Brian set up my appointment times and scheduled me for the electrical inspection so I didn't have to do any of that. The inspector was here this morning and told me that it was really nice to see good quality electrical work. I would not hesitate to refer them to family and friends, I am happy with the job they did for me."

"Drew, the owner of Walker Electric was the technician that actually showed up to do the work. I had him install a ceiling exhaust fan in my bathroom. He did excellent work replacing the old one with new and didn’t do any unnecessary drywall damage. I also had Drew install under cabinet strip lighting in my kitchen that came out looking wonderful. His pricing was more than reasonable and his quality of work was top notch. I would recommend Walker Electric for any of your electrical needs and I will absolutely be using them again in the future!"

"Having owned four different houses the past 16 years, this was hands down the best experience with a plumber... ever. We hired WyattWorks to install a laundry sink (the stainless over cabinet kind) which required drilling through the floor to tie-in with supply and drain pipes in our basement. Jeremy performed the work flawlessly and was a true pro: measure and recheck, plan and dry fit, and clean up the work area during and after. The whole process from start to finish was painless!"

Generator Install questions, answered by experts

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.
