Upon my arrival in Smithville, for an AC service, the customer had concerns with the HVAC system not cooling. I performed a diagnostics and found that the system was not being supplied with high voltage. I checked the breaker panel and the 30amp fuse was turned off to the outdoor system. Before turning it on I verified the refrigerant circulation pumping system was not grounded and the voltage enhancement system was good. After supplying high voltage to the outdoor system I tested its operations and found everything operating properly at this time. I spoke with the customer about what I found today and also went over our maintenance program. She is interested in joining it again but the ac just went out in her car so she wants to that fixed first being she is month to month on expenses. I will follow up next month about the maintenance program.
