My heat will come on but when I turn on the AC or Fan nothing happens. I hear the outdoor unit turning on but nothing comes out. Tried resetting t-stat and turning breakers on and off. Any ideas?

Thanks

Unless you have a heat pump... they are totally different systems with different hardware except the thermostat. Which do you have? I'm assuming you don't have a heat-pump and your A/C unit has some problem. Without the right tools and the know-how to use them... short of checking for tripped breakers there isn't a lot you can do but call a HVAC repairman.

I live in a condo, the unit inside is a Nordyne GB3BM-024K-A-10B and the outdoor condensing unit is a AeroSys THDC-24T

You still didn't answer the original post. What type of system? Gas heat/electric air or a heat pump?

Its an electric air system.

Meaning you have electric heat in the winter (with the big electric bills)... this system does not function at all when its cold out?

Heat pumps are basically a reversible A/C system which I take it to mean you do not have.

You need to get an HVAC guy out there... there are a number of possibilities... including a Refrigerant leak.
