New Central Air AC unit undersized?
Had new Central Air installed. Outside temp averaged about 70 degrees on this day. Previous 3 days were 90s, so indoor temp was 80 when new AC unit was started up.
It took about 7 hours for the temp to drop from 80 to 73 (at 11:30 pm with an outside temp of 67).
After 15 minutes thermostat was up 1 degree to 74. AC kicked on and it took 20 minutes to go from 74 to 73.
20 minutes to cool 1 degree with outside temp at 67. Is this AC unit too weak?
