"We've used Reliant Assembly on many occasions. Kenny does a terrific job. He's versatile and easy to work with. He even put up about 20 feet of outside fencing for us, which was a kind of job he doesn't normally do. Nonetheless, he did excellent work. We strongly recommend Reliant Assembly."

"Luis was professional and courteous, offering a detailed explanation of the problem. He's very knowledgeable and was able to explain the issue in a way that I could understand while still using technical language. I really appreciated him taking the extra time to be sure I understood the root cause so that I could make an informed decision about whether to repair or replace my unit. I will definitely be contracting this company for a future installation. Thoroughly impressed!"
