Our old A/C unit broke down about six months ago and one our closest friend recommended Nonstop Air to diagnose and solve the problem for us. Nonstop Air showed up and were super helpful. They were honest and supportive. They educated us on how to keep our unit clean and also what changes would be beneficial to keep our facility cool. Since we installed two new units with them in different parts of the facility and the service has always been prompt and on point.
