Unit was not operating upon arrival. After further inspection I found that the ac fan motor has completely failed and therefore is not allowing the system to cool properly. On top of this I also found that the indoor fan motor is not running due to a relay switch that has failed. Another concern I found is the compressor does not seem to be operating correctly either. On top of all of this there could be even more going wrong with the rooftop unit. Overall with all of these findings I believe that the best thing to do would to be looking into replacing the entire system due to age and high cost of repairs needed in order to get the system up and working properly, and avoiding high costing repairs.
