Upon my arrival I spoke with the customer about his concerns on the hvac system freezing over. I performed a diagnostics on the system, checked the amp draws, temperature split, pressures and air flow of the system. I found that the air movement system kept surging while I performing the diagnostics. Upon further inspection I found that the air movement system is faulted. Spoke with the customer about his different options for repair and he chose to go with HC6E. We will need to schedule a return date to perform the repair and customer would also like window units if the repair can’t be done soon.
