excellent
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.
Had some heating issues with my HVAC system. Called these guys on Saturday night and they were available to assist and send somebody out immediately. Very professional team. We were very happy with their service and would definitely use them again!
