I would have the dealer check the dip switches to make sure they are set up right.
I have the TUY80r9V3w4 w/ 2Ton A/C, set at 400cfm/ton and I don't hear it running unless I am right in the utilty room next to it...
I agree with the other guys, It has been a hot summer in most area this year, and cause the system to run more.
in A/C mode, the blower only runs in single speed on a single speed compressor.. W/ Comfort-R on, the blower starts off slow for a min, then ramps up next speed, then after 7 min, goes to it's set speed, and stays there till there is no call of cool.
In heating on 2-stage, yes the blower will go from one speed to another when the t-stat calls for 1st or 2nd stage.
Old yeller made a point bout "Run less"... Mine runs pretty much steady all afternoon and keeps temp on a hot afternoon.
