Walgreens, St. Louis MO Maintenance "Howard, just wanted to let you know that in the 2-3 years we have been getting the RTU’s 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 winter time. 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."

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 existing rooftop A/C units …"
