On this job I looked at both heating and cooling. Issues Heating up stairs. System has an issue turning the heat on. This is due to a faulty thermostat. Cooling down stairs. The system has started take bites out of the disconnect key. This is due most likely to the high inrush amps. Cap is out of tolerance System needs soft start device new disconnect and new cap size 70mfd currently reading 66 Recommend both system have this done on the cooling side. Downstairs system needs 410a recharge. Super heat reads 27° indicating a starving evap coil. Should be 15° System have been cleaned.
