I'm not sure even the name of my AC unit there is not a name anywhere on it, but I do have model # CA3024VKA1, manufacturer# NCA3024VKA1. I did call a friend that works for an heating & cooling company & he told me that the unit was more likely to be a tempstar or carrier & that with the model being so old they would not have the wiring schematics. The air conditioning unit is 1 1/2 ton split unit. I know where the wiring schematics are located but I can not make it all out d/t how old it is. Any help would be greatly appreciated.
