Looking over cooling system in Braselton Georgia . Second opinion on the upstairs system . System is slightly low on R22 charge and showing its age , the indoor coil is very rusty took pictures . Talked over some options on what we can do . Family has a home warranty and at this time they don’t want to put any repairs on the unit and they want to let it ride and get it through the little bit of warm weather we have left since it’s almost winter .
