Dispatched to investigate concerns, Carol was having about her system. The maintenance was just performed yesterday. I verified the primary drain is clear and flowing at this time. Filter is new. Check the charge and the refrigerant is 100%. I recalibrated the thermostat. It was actually reading 4° warmer than what it actually was in the house. I advise Carol that it would take at least an hour to meet the demand that she is requesting at this time. Otherwise system is operating at manufacturer specs at this time.
