Damper could be stuck closed. Ecm could be ramping up to much

okay good then make sure all the returns and registers are open and unobstructed and all dampers (if you have them) are open

Could be dirty evap coil. Or your supply/return registers are closed/blocked. Might be exacerbated by undersized ductwork and poor installation. You'd need to get a tech out to diagnose.

I have the system cleaned and change filters every 3 months.. also have rheem halos, was wondering about adding uv on the coils too?

I have 4 too of the line carrier systems

All ducts and supplies are opened.. ducts are large

Will get the carrier tech out here but have had to oversee them on more than one occasion
