My customer upon arrival. Customer led me to the unit that's in the basement which is the new unit. Notice that the polarized filter was not plugged in and also replace correctly. Removed old filter put a new filter correctly and put it in and make sure it was plugged in. Turned on the first floor thermostat to see the condenser running it did. Unplug disconnect to wash down the condenser. Plug the disconnect back in. Check pressures on the condenser the pressure and the temperature split were good. Went upstairs turned on a second floor unit also pulled out that disconnect to work on it cleaned it inside out wash it down with chemical and water put it back together and play disconnect back in. Change the filter in the Attic as well.
