No AC, upon arrival both thermostats were satisfied at 74. Turned both on, noticed small amount of water around indoor unit in basement. Checked charge, found unit low on gas, watched water fall off of coil, this is common when low on refrigerant. Added 1.5 lbs of 410a, charge is perfect now. No more water fell off the coil, checked and confirmed drain was not clogged. Cleaned up water on floor. Tested both thermostats, working great. Unit has to have sprung a small leak, charge was good during maintenance in April. Would suggest a $185 leak search, or just wait until spring and we can look for it during maintenance
