Upstairs system needs secondary water safety installed inline with the pvc. Black mold growth inside supply plenum. Recommend installing u/v lighting system to kill mold and bacteria. Evaporator coil showing advanced signs of wear and will need to be replaced soon. Down stairs system showing thick black mold growth. Recommend u/v lighting for that system as well. Condensate pump sits outside of pan, if pump safety fails it will flood basement recommend small pan just for pump and water safety switch. Outdoor units both slightly low on charge. Both capacitors are metering writhing acceptable ranged but have extensive corrosion. Units are 12 years old. Recommend hard start kits to lower start up amp drawl and noise. Cooling is operating normal at this time. Changed upstairs filter, downstairs filter was clean. Added bleach to drain lines and pump.
