I just had one of our units repaired the other day (Zone 2). Everything was running but there was hot air coming out. Turns out the capacitor was blown. This unit has been repaired so many times and every 6 - 9 months something else goes wrong. Certainly cheaper than buying a new unit but no air in the summer is not much fun. Good thing our first zone never breaks so we can always keep cool on the first floor.

same symptoms with my unit a few weeks ago. blown capacitor.
Bearings and Capacitor is a good place to start.
Another common problem is a pressure switch on a tube that comes out of the compressor. It's purpose is to turn on and off the outside blower motor to keep the condensor cool. If it is bad, you can short the wires that lead to it out. That way, the blower motor will come on every time the compressor comes on. If that is it, it will keep it running until a service guy can come (saving emergency charges). Ive even run some units like that for relitively long periods of time.
That switch has to be replaced by an AC tech because the coolant has to be drained, a tee installed and it has to be recharged.

Repair guy just left. Worn motor and the bearings are sealed. Capacitor tested fine - it used a single housing that had two capacitors in it, one for compressor and another for fan.
He was really good, added a separate capacitor just for the fan, checked and adjusted coolant, something called head pressure and cleaned it out. 324 bucks, not too bad considering got a checkup as well and 2+ hours of labor.
