Arrived to do a performance maintenance. Set system for cooling. Measured the systems static pressure measured a temperature split between return and supply air. Checked interior of the furnace for cleanliness. Went outside and verified refrigerant levels. Verified operation of all electronic and mechanical components. System is inverter driven and refrigerant pressures and amp draws are continuously fluctuating according to the systems demand. Rinsed coil free of debris. Spoke with homeowner about the system. Air conditioning system is operational at this time.
