Just had a brand new goodman 13 seer system installed. It was fine for 1 week while we were away. Came back with weather temp in high 90s. Set therm to 72. Brought house down to same. Later that night the house didn't feel so cool do we dropped thermostat to 64. Next morning the unit froze up and flooded the house.
Had it fixed and now the inside unit is making a high pitch loud whirring sound. Can't sleep with it. I'd appreciate any insight into this. Have lost any and all confidence in Installer .
