“Corey was the service tech that came to my home to service my ac unit.
I can say he was one of the best in home service personnel I have worked with so far. He was very respectful and knowledgeable. He was able to explain to me in terms that I can understand exactly what was wrong with my ac unit. I would recommend this company to anyone I know especially if they be lucky 馃崁 to get Corey that shows up”
