I performed a system check today on a 2010 Trane unit. I changed the homeowners filter, verified the overall operation of the thermostat, inspected the system for cleanses (microbial growth development), on the evaporator coils & blower wheel, check the draw on all electrical components, inspected the capacitor, inspected the contactor, verified refrigerant, pressures & temperatures, flushed and vacuum the drain line, and wash the outdoor unit coils. Thank you for choosing Total Air….. See quotes for recommendations…
