We just a got a new Lennox 2-stage air conditioner in February. After several months of operation, it appears that Stage 1 and Stage 2 cool at the same rate. Does that seem right? Shouldn’t Stage 2 cool faster? I’m wondering if this thing’s installed right. A screen capture of the data from beestat is below showing Stage 1 and Stage 2 on almost identical plots for cooling rate. I have Ecobee set to cool at Stage 1 for minimum 15 minutes - and then to move to Stage 2 if necessary. But when Stage 2 supposedly starts, I don’t hear a noticeable difference in fan speed. But Ecobee and Beestat tell me Stage 2 is running. Help! Do I need to get a commissioning agent out here to check the installation?
