Question about American Standard Heating & Cooling
What I would do first is to compare the wiring between the unit that is not working to one that is. Make sure thermostats are hooked up and set the same. Check t-stat wiring into furnace and from there to condensors.Check voltage into contactors on a/c.With t-stat not calling for cool there should be 220-240 volts across input leads.Turn t-stat to call for cooling and contactor should close and compressor come on.If the contactor does not close then double check all t-stat wiring or replace stat
I would check all breakers an fuses if so equipped. If these units are all new can't you have contractor take care of it under warranty. Thank you
