[Denny and Angie Miller]

Thanks to this forum, I went out and checked for some of the a/c issues other members are experiencing. I removed my return air grates and found both of my return air ducts collapsed down to about 1" opening. Like others, I used some pvc pipe cut into 6" sections and inserted them into the duct to hold it open. I haven't measured my air flow, but i could tell the difference just standing under vents.
