Washed condensers with water. Note: recommend that capacitor on condenser for downstairs be replaced at next visit
Checked the trane furnace and found a burnt up indoor blower. The heat exchanger is bad on this furnace and the unit is very old. It is recommended that that the furnace and the indoor coil be replaced. If the motor is replaced the burnt smell will still be present.
