Ac was not operating upon arrival. After further diagnostics I found that the system had no high voltage at the ai conditioner. I hen found that the two high voltage fuses have blown. I replaced here fuses with brand new ones and he system started right away. I also found that the company that installed the furnace never connected the ac to the control board. This was causing the fan to run at a very low speed. I then ran new wiring to the furnace from the existing wires inside and wired everything up accordingly. As of now the system is up and running however due to the age I do highly recommend looking into replacement. Home advisor visit scheduled for 6-28-2022 at 5 pm with our home advisor Chris A.
