Customer had downstairs thermostat in emergency heat mode on arrival. Tech recommends standard heat mode. Customer wants to make sure system is working properly before summertime. He reports the front right 2 rooms are not getting enough cooling during summer. Both have only one supply register. Tech tested system. Found no bypass damper on system. Zone dampers are set up to not shut all the way in the closed position. Recorded refrigerant pressures and amp draws. Tech suspects no major issue with 2.5 ton system. Need to call early next week to have field supervisor evaluate front 2 rooms and comfort challenges with house. Need to evaluate 2.5 ton sizing.
