Walgreens, St. Louis MO Maintenance "Howard, I just wanted to let you know that in the 2-3 years we have been getting the RTUs with the Trent CostGard™ drains on them, the evaporator pans are the cleanest we have EVER seen them! There's a little residue and dirt, but nothing like the old-style 'TRAP' that just clogged up in the summer and froze in the wintertime. The pans have been clean for the most part, and that has helped to eliminate quite a few emergency calls regarding water flowing back down into the stores from a clogged drain and overflowing evaporator pan. They truly are paying for themselves, and we wanted you to know."

Kentucky Fried Chicken, East TX "Most (95%) of our roof leaks can be traced back to faulty drains from our HVAC systems. We will send your instructions for installing the CostGard™ Condensate Drain Seal to our A/C contractors when we build new restaurants or replace old rooftop A/C units ….."

Brook Hill School, Bullard TX "…your product promised a possible solution to foul odor in our flagship building. The results were phenomenal. Immediately, the odors disappeared, ending 14 years of undesirable and unpleasant occupancy… there have been no malfunctions and no service calls, and the air handlers are now dry inside. … we will be replacing all our trapped systems with your product."
