I would also like to take this moment to express my great appreciation for my technician Bruce. He’s like family over here at Warehouse Direct (and one of the best HVAC guy’s that I’ve had the privilege of working with!!!) Curtis S.

I wanted to let you know that it was a complete pleasure working with you on the TJ Harkins project. Ryan and Tom K. did a great job and the field guys were great to work with. Everyone came to work ready to do a good job and with a great attitude. Today we had a orientation meeting with the owner, Jerome and Rich were completely professional, patient and knowledgeable. Keep up the good work. Scott R

I just wanted to drop you a note telling you how pleased I am with John’s team. This project has not been easy from day 1. John’s team has fought through all the adversities they have faced with tremendous fortitude and desire to succeed. Recent events with large RTU were resolved with John’s team quick response and help. The teams dedication to success is greatly appreciated. Tony L
