What seems to have worked for us with the Whisper Quiet AC. We opened each return air vent with two 10" lengths of 3/4" PVC (it's what I had laying around and worked well). We also cut the extra off the sleaves of each supply vent and cut every other louver off 5 supply vents (the others I left to direct air away from thermostats etc) and used aluminum tape where the factory didn't do so well. The last two days have been in the middle 90's, with us in full sun, and we have been comfortable, without any extra fans, and not had any freezing up with the A/C fans running on auto. Sometime before next summer (when we might see 121 for a heat index again) I'm going to open up some of the return air holes where they still aren't cut completely open.
