Consider that this heat is not just in the air inside, but also in the seats, dashboard, floor board, roof, door panels, etc, (essentially the entire inside of the vehicle).

It isn’t blowing cold enough

June 29, 2022

"It isn't blowing cold enough.” Most any auto repair shop that does A/C work will often hear customers say this phrase. It can be the result of any number of things that can be wrong with an A/C system.  Often it is a case of common things such as, a low refrigerant charge, a refrigerant overcharge, contaminated refrigerant,  a blend door issue, a cooling fan problem, or maybe a weak compressor.
