That's the funny part. There are 4- 5 ton heat pumps total. The 2 over the sanctuary are all flex and just about every piece was destroyed and yes there were babies and they caught 2 other adults. But the other 2 units that serve the rest of the church are all fully insulated metal duct. No one knows why it was done this way. My guess is they were running low on funds and went the cheap route with the flex.
