Topic	PSA: Your AC can probably only handle lowering your living area 20 degrees
chrono625 07/21/19 11:13:32 AM #26:	IdiotMachine posted... We have a 5-ton unit for our home, and it was freakin 81F in this house during the morning (when outside it was 95F peak). Only now, with the sun down, is the inside temperature going lower and lower. We hired an HVAC tech to come take a look, and he said the unit is undersized for our house (approximately 6,400sqft house). He recommended a light commercial unit of 7-tons or adding a split unit in the main hall. 500sqft per ton is rule of thumb for HVAC sizing. For 6500sqft, yeah 5 ton isn't able to handle that. You should realistically have two 5 ton units for the entire house. --- https://imgur.com/Rqk1DYV - Super Bowl XXI/XXV/XLII/XLVI Champions - NY Giants Eli Manning SB tracker: 2/2 Superbowls 2/2 SBMVP's <cite>chrono625 posted [p:924981022] in PSA: Your ...
