I have no drip pan at the bottom of the AC unit installed in 2018 and located in a utility closet in my living room. It was installed by the same company does my yearly check up. This year they noticed they forgot to put a drip pan in 2018. They said they are going to install it but have not yet. The job will take two people to remove the furnace (on top), then the AC, put the pan in, then reinstall everything.
I want to know if this can wait or is urgent?
