Perform system maintenance on multi head unit inverter. System Has two head units & 1 Condensing unit. Debris buildup across coils on indoor & outdoor coil. Clean outdoor coil using water only indoor head units are going to require a light chemical clean As well as blower motor as you will be able to tell in the pictures from buildup and debris, causing a lack of airflow on both and coil. I need to get with homeowner about pricing to clean indoor blower fan blades And clean indoor coils in place with light chemical/ water usage.
