Luis & team are awesome! My AC went out during one of the hottest weeks of the year. I called a few places before Cornerstone, and was told I'd have to wait at least a week for a new unit. I gave Luis a call, and within two days I had a brand new AC & furnace installed for a fair price.

My heat went out on a Thursday. Called Cornerstone on Friday and Luis came out that afternoon, right on time. He quickly diagnosed the issue and let me know my options. Luis was able to get my heat running again with a temporary fix, and gave me a very reasonable quote for the long term repair. I wIll be giving Cornerstone a call if and when I need service again.

I am very pleased with their service mostly their customer service and quick turnaround in responding. I used their services to install my central AC. They were quick, efficient, affordable, and very professional. During hurricane Ida I lost both of my water heaters, I called Luis and the next morning he was installing new ones. The turnaround time of their service is impeccable. This is a company I can count on, they are truly dependable.
