Question
York condenser unit located outside (model #TCGD48S21S1A), with evap coil and air handler in the basement. New construction, installed last fall. Unit never blew cold air from the day it was turned on. Coil iced up within a few hours of being on. Filter was not clogged and another contractor who's looked at the system says my ductwork is adequately sized. Also, the coil itself is clean and unobstructed. I let the unit thaw and when I turned it back on, the compressor was making an awful grinding noise. Contractor told me that liquid refrigerant got back into the compressor and ruined it, and thus, I'm screwed, and he can't help me. Are there other causes for iced coils besides airflow problems, like maybe an underperforming compressor? Thanks for your time.  

Answer
Kyle,
There are other problems that can ice a coil,
If your system is less then a year old you should be covered for a new unit labor and material.
I don't know what you got in the way of paper work from the contractor but you need to take him to court.
York should replace the the unit no charge and maybe even give you an allowance for labor.
Get ahold of your nearest York rep.
