Daughters AC quit working tonight. It’s old unit working fine until power went out. Coils frozen. Changed filter. Thawing out but so far not working. She called one place that can’t come out until Wednesday. Didn’t know if any recs for good faster service especially since she may need to replace unit. I think it’s about 30 years old. Hasn’t owned home long and she knew ac may not hang on much longer. I’m out of state. Thx!
