      Mastercool question: I have been using Mastercool for about 25 years and have two 6500cfm units on my roof. I have a problem with one unit this summer that is a mystery to me. I have new pads (40x28x12). They are completely soaked with water (ie: the pump is working fine). I have a new belt on the system so that the two speeds work fine. The pads are tight at the front so that air can't get around them. The unit is closed up properly. The duct work is intact and not broken in anyway. The barometic damper is out of the system so that there are no restrictions to the airflow. Everything seems perfect... except it's not cooling very well. The other unit (same water supply, same exposure etc.) is cooling great, but this unit is about 10-12 degrees warmer. Any ideas what to look for? I can't figure it out!
