Natalie: Dan! I spoke to building maintenance about the air conditioning, they're sending someone up.
Dan: The air conditioning...
Dan: That's good, ummm, but the problem we're having in the studio is with the heat.
In any modern commecial structure (as well as most domestic facilities), the two, heat and air conditioning, are a part of the same interrelated system, usually known as "HVAC" (heating, ventilating, and air conditioning). Someone sent up to deal with problems in one would be able to deal with the problems in the other. Unless the entire structure is having lack of heat issues, a problem like this most likely would relate to a valve not opening properly to allow the heated ventilation into the area. Dan's concern with the nature of the problem is irrelevant.
