If it is an apartment, chances are it is a Goodman(Janitrol) air
handler. If so, the problem is the blower relay-- they had nearly a 100%
failure rate on the older type relay they used. Even if it is not a
Goodman, from what you describe, the blower relay would be the first
thing I would suspect. Larry

If they focus on the freon levels when it's the inside blower that
isn't coming on, then you're hiring the wrong people.

No research done here by this idjit!

If the outdoor unit is starting up then the low voltage circuit is good, and
there is no problem with the thermostat. Your
problem is with a fan board or relay, or the motor may be overheating.
Take the black wire from the motor and wire it directly to the power comming
into the furnace. You can bypass any board
problems and use the a/c. This only applies to a direct drive psc blower.
