Tech Cody arrived to customer's home and met the homeowner. System is a 6yo Goodman furnace. INDOOR: I replaced the filter, the blower is clean, the blower motor is in good condition, the blower capacitor is within tolerance, and the coil is clean. The furnace went through all of its safeties with no issue and began to operate normally. The system had a UV light installed and it was functioning properly, and the system had a 18 degree temperature split. OUTDOOR: I washed and waxed the unit before taking any readings. The compressor and fan motor were operating within manufacturer range, the unit had a compressor saver installed, the capacitors were within tolerance, and the primary electrical control was in good. The refrigerant charge was within acceptable levels at this time. I shared my findings with the homeowner and left the system off at the thermostat per the request of the customer as I left.
