It wasn’t cheap, but from what I understand freon is really expensive. You know my calculus professor at LSU invented a fridge that used CO2 rather than freon. CO2 is pretty cheap. Just throwing that fun fact out there. But, yeah… Le, the technician, was cool and respectful and seemed like he knew what he was doing from experience rather than a stint in trade school. He diagnosed the problem that a previous tech from another company had missed(I don’t know how!!!), and now my AC is cooling my house like it did in the good olé days. Thanks Le
