No because I'm not there, but HCV's are a common failure mechanism, failing open, so there is always heat going. If you have HOT air coming out, then HCV is probably open. This doesn't eliminate A/C problems that could be happening at the same time.

My A/C went out (evaporator coil got leakes), and after that was fixed, the shop found the HCV was stuck too which just amplified the problem.
