i mean, por kilo ang bili ng shop from their freon supplier, hindi por psi.
my guess is, they charge a higher price, so that whatever amount of freon they give you, ay siguradong bayad na sila at hindi lugi ang shop.
they probably made prior calculations, that with an increase of xxx psi, the weight of freon given is a maximum of yyy kg, and charge accordingly. anything less than that is pure profit.
