Well it was an "refrigerant" weekend!!!

[67Dart273]

So it's been 2 years for the 86 Ranger (some R-12)

Either 2 or 3 for the 95 Olds (some R-134)

and I believe 4, maybe more, for the old Lennox heat pump, now A/C only (some R22)

Hell we had a couple of rainy days before the 4th it was only 49* F!!!!
