"Beware!! As you can see high voltage electric cables were installed through a rough, sharp sheet metal housing without the proper circle grommet. This is a clear and present danger to myself and future service workers. It only takes a small amount of pressure to cut through the wire sheath and cause a catastrophic situation. This is a safety violation and I urge you to have your HVAC inspected if Evans did the installation Also, I was charged for work not performed."

"No doubt they hire great installation people, but their communication and honoring their quotes has little to be desired. I will elaborate. I was given a quote, left on my voicemail. I responded the next day letting NRG know I accepted their quote. 1 week later I received a phone call telling me they wouldn't honor the quote give, and they cited the reasons as Tarif's. This was back in April 2025. I still went with NRG, albeit at a$1000.00 increase. The second reason I wouldn't recommend this company, and this for me is the final straw, after installing my solar NRG didn't let me know I needed to have an ESR release, in layman's terms this is necessary for your power company to accept your new solar system. I found out this information when they contacted me in August 2025. NEG blamed the company who upgraded my Electrical Panel. NRG INSTALLED MY SOLAR AFTER THE PANEL WAS UPGRADED. Since this company doesn't communicate with its clients I would say go with another company."

"You know who you don't want to p*** off? A tired mom who hasn't got any sleep or air condition in six weeks during a heat wave after failed services from this business. Rockwall one hour air has been out to my home 5 times in the last six weeks. During this time I've paid for parts and labor for an issue that was never resolved. On the last visit, Josh came out to my house. He pointed out a leak in our attic that had been overlooked by our previous technicians on their previous visits. He apologized and told me that that service fee would be waived for the trouble. After days of waiting around with no response during a heat wave I called. They told me that I owed a service fee of $90 for that visit which the technician had already told me would be forgiven as we have been annual members with this company for over three years in my new home. During this time I've been up-charged for parts, and been billed for services/parts that never addressed my issue. Their manager told me that they would not come back out to my house to fix the problem unless I paid yet another service fee. During this conversation, I was hung up on, and all of my calls from my husband and I have been ignored. If you're reading this, please save yourself the headache."

"They did a great job and met my schedule perfectly. Jason was a huge help in the completion of the task on time. I would highly recommend them and I would definitely hire them again."

"I am pleased at the customer service and speed of feedback from C. Woods Company. Our technician was Paul Herndon, and he was great to work with. He arrived on time, and was very polite and courteous, and very knowledgeable. I will be happy to review further once the work has been completed."

"It was efficient and prompt. The insulation was great. They made an appointment to start the job. The work they did was installed very nicely and they cleaned up."

"Charged me $350.00 to install a $18 transformer. Spent less than 30 minutes on property total, Two trips. Didn't check anything else, clean coils check condensing unit- NOTHING. Asked them to adjust the gas for the furnace heat start and they said they didn't have the tools. It takes a screwdriver. I think it was-I don't know how. When I asked their office about the outrageous fee, I was rudely scolded and told they were the cheapest in town."
