Air conditioning repairs Unit #1 Very low charge on r22 system. Made customer aware of the situation. Customer is looking into unit repalcement options. Unit #2 Thermostat was set to heating mode. Turned cooling mode on and air conditioning unit is working. Made customer aware that with only one unit running out of the two, this unit will be running hard and may never shutoff since it will not be able to cool the whole house. Customer will be in touch with sales advisor.
