A/C was recharged and now it's blowing only warm air.
First off, hello to all of you! (First post on here)
My c300 was recently recharged with 134a freon. After the recharge, it started to blow only warm air. When I switch the temperature to hot, it blows out hotter (minor detail). Everything works, as far as the ac components go. It was working perfectly fine until the recharge. I have no idea what's going on, and would appreciate all of your help! Thanks in advance. If more info is needed, id be glad to answer. (Yes, I did push the ac button to activate it, and the vents are open)

When "recharged' do you mean from a can?

You mentioned "it was working perfectly fine until the recharge". Then why did they do it or why did you let them? There are so many shops out there that think freon always needs 'topped off' or convince people it does. A/C systems, HVACs or autos are sealed systems. Freon does not just 'vanish' if the system is sealed and operating properly. Freon is a gas and is only needed when there is leakage. If they overcharged it like others have said, the pressures will be too high and the system will not engage. Grab a guage kit at advanced auto or pep brats and check the low side pressure. It should be between 25-40psi depending on ambient temps.
