Drained water heater and diagnosed the ac. Unit is operational but it is very low on refrigerant causing unit not to cool. The ac uses refrigerant that is banned to be produced due to the harming effects of ozone layer. Recommend replacement of ac due to having to do leak search repair, add an old refrigerant that is hard to get, as well as compressor going out due to the low amount of refrigerant. Chance will be coming out on Tuesday to give client options.
