Q: AC blowing hot air after engine replacement

asked by on

The AC is blowing hot air. The engine was replaced only 1,000 miles ago.

It sounds like your air conditioning has lost a charge. The refrigerant may have leaked, or they may not have charged the AC when they replaced the engine. I would have a technician come out and inspect your entire AC system, charge the AC, and inspect it for leaks.
