    problem with blower
    An a/c co. had installed in my house & garage AMANA 16.7 seer a/c. 4 T cond. 2 speed M# RSG48C2A, Ultron R-410. 95% variable speed AMV90704CXA furn. And 5 T evap. CH60FCA. House 1,530 & garage 462. City inspector req'd all supplies removed from garage before approving permit. I have a WHITE-BROTHERS 90 Series Premium 1F95-391 Humidistat. If COOL FAST if set to ON it will bring 2nd stage of cooling on any time you manually lower the temp 3 or more degrees below room temp. If COOL FAST is set to OFF, the thermostat will delay 2nd stage from 0 to 30 min. based on how well the 1st stage is keeping up with your setting. When an interior door is opened I believe the flow of air is far too great, especially when 2nd stage is operating. Will you please share with me, my alternates? Thanks, Terry Mishler

    Have the contractor come back and adjust the blower. You paid good money for there service so it should work correctly.
