Arrived to do a performance maintenance. Set up for temperature split and static pressure tests. Verified operation of all mechanical and electronic components of the air handler. Verified operation of the heat pump and the electric heat strips. Checked blower for cleanliness and to see if there is any play in the bearings. Checked cleanliness of the indoor coil. Moved inspection outside. Found heat pump coil clean. Verified operation of the heat pump components. Wiped system down. Air handler filter will need replaced eventually but today it has plenty life left in it. System is functioning properly at this time.
