Why don't the A/C makers put an EXO integral with their units? I've wondered about this for a long time. Seems like buying a new car, and then having to buy the steering wheel seperately (you've got to have one)
You'd think that since the HVAC guys can do only a limited amount of work that they could get it right. I guess that's to be expected when there is so little inspection & so many grandfathered licenses.
I'm sure they used schedule 80 pvc (300-5(d)) so the weed wackers & lawn mowers won't cause any damage.
Few things are harder to put up with than the annoyance of a good example.
