Arrived to do a performance maintenance. Set system for cooling. Measured the systems static pressure measured a temperature split between return and supply air. Found the system operating with more than double the static pressure the system is rated for. Reached out to a field supervisor to finish the diagnosis on the systems static pressure. Went outside and verified refrigerant levels. Verified operation of all electronic and mechanical components. Rinsed coil free of debris. Went back inside and checked interior of the furnace for cleanliness. Spoke with homeowner about the system. Air conditioning system is operational at this time.
