a/c blows hot air,looking for a shop
 

My wife is on Manchester now and keeps on calling me for her a/c problem. When she starts her car the A/C also runs but then it only blows hot air after she starts driving. Told her to have her freon re-charged yet after this the problem still occurred. I cant help her since she is there. the car is full of freon now but it just blows hot air. And if anyone could recommend a shop there on Manchester and other contact details. I've found one from New Hampshire auto repair and saw one named A1 auto body inc. If anyone here has tried this,please leave some comments. thanks

What kind of car? I know my past BMW's A/C is tied to the outside air temp sensor. Prevents the car from blowing cold air when it's "cold" outside. Problem is, if your sensor breaks, the car reads "-40F" and thus won't blow any cold air.

It's a 2008 Nissan Altima Coupe 2.5 S.

Did you try asking on an Altima forum? That's kinda weird posting an Altima problem on a Z forum.
