We had an unfortunate situation with a contractor working on an adjacent condo unit who accidentally hit my AC line in the wall causing my system to go down. I called Cuestas and within 2 hours Dennis was at my house. He very efficiently and quickly repaired the line and charged my system and got my AC back up and running. This is the second time they have responded quickly to my call. I have been in PSL for over 30 years and used several different A/C companies, but by far Cuestas is the best company I have ever dealt with. Their customer service and their follow-up phone calls are indicative of their professionalism. I highly recommend Cuestas Air Conditioning.
