Cornerstone air is great company they were recommended to me when my previous a/c company that I had been with for a decade could not trouble shoot my ac problem they caused. I paid cornerstones service fee and he gave me some options and one was to replace my defrost board my self since i need to save money for a whole system. I took his advice and now my ac works again. In the fall when we have the money saved for a new unit they will definitely be my new AC company going forward. Thank you for help.
