Debbie F.
Adam did a great job of quickly analyzing and diagnosing loss of AC cooling - plugged ac drain line. Thanks!

Philip E.
Design Aire provides very professional and friendly service. We've been customers for 30+ years and have been very satisfied. They are very good at explaining and answering any concerns. They expertly test, clean & maintain the systems (including repairing any damage caused by rodents interested in the wiring of our outside unit). This latest visit fixed our humidifier at a fraction of the cost of installing a new one. Highly recommend!
