Arrived to water on the floor from a leaking air handler drains are clear. Noticed water dripping from the back of the drain pan. Due to the location of the drips the technician believes it to be a crack in the pan. Tried to locate the crack but could not get to the back of the unit to see. R22 system installed in 2009. Dual run capacitor is weak and needs to be changed. Compressor saver had failed and needs to be replaced. No drain protection has been installed. Blower wheel and evaporator coil are very dirty. Due to the current issues replacement is advised. Comfort advisor is coming tomorrow evening to speak with the customer.
