"Mr. Green TRULY puts the customer first! He installed a whole house generator for me last August and called to check on us 6 months later because bad weather is coming. Brought me a key and showed me (again) how to add oil. I had several estimates and he beat other prices by several thousand $ AND he installed a bigger generator! I will definitely hire him again and recommend him to every one!! 5 star service *****!!"

"They are a busy company and I can understand why. It seemed like things were slow but a lot was going on behind what I could visualize. The permits and the Net metering agreement had to be approved first. After that the work began very fast. The waiting on Duke energy was a couple weeks after everything was installed but the results were extremely good. I now have a system that cools the house properly. My power bills went from $320 a month to $9.18 and even with the solar payment I am saving hundreds of dollars a month. The crews were very professional and did not take any short cuts. In this world everyone wants immediate installation and results but somethings take a little time to achieve the results expected. The company kept me up to date with the progress and the channels they had to go through to complete the process. They are very customer oriented and I would recommend them to anyone who was to save money. You have to have long term goals. Mine are going to be achieved with the help of U S Energy solutions. I thank them very much as they not only made me feel like a special customer, they made me feel like part of the family."

"Quite honestly, this was not the lowest cost proposal I received for this project. If it wasn't for Ron I would have awarded the work to someone else. But Ron convinced me that there was a price for quality, and that I could trust them to deliver. I made the RIGHT decision. The installation is beautiful. Better than the original roof. When they arrived, they worked non-stop. When the project was complete, they cleaned up better than it was when they arrived. There was never a question on what was included in the price, and the workmanship is exquisite. big 5 stars."

"We were affected by Hurricane Helene and had no power. I was running extensions all throughout my house to my generator and it was an absolute mess. I called Greg seeing if he had availability to hook my generator up to my breaker box and told him my situation and how we had no idea how long this outage would last. Greg wasted no time at all to get over here. He was very professional, punctual, funny, and kind. He had my generator hooked up to my breaker box in less than a hour and it was such a blessing. We ended up going 5-1/2 days with no power and it was so much easier to bear this storm with my 3 young kids thanks to Greg’s work. We will definitely be calling Avila Electric for all of our electrical needs!"

"I was very impressed with Keen and the crew. As a former remodel contractor (now retired) I know that contractors like Keen are a very rare breed. Honest, reliable and does what he says he will do when he says he will do it. He is the kind of contractor that everyone wants but rarely gets. Yes... I will have him back for a larger project. They started here installing 85' of underground wiring, installed a new panel,new breakers,outlets and a surge protector to cover the entire home and outbuilding. All in Tripple digit temperatures without any delays."

"Corley is great when it comes to routine service checks. They always make suggestions of what can be done to improve systems and provide the costs up front. I personally find that to be expensive so I rarely agree to have anything added. I would recommend them for your routine checks!"

Generator Install questions, answered by experts

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.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

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. 

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.
