Case reports · Aircon cleaning

Wall-mounted aircon clean with foam over the coil: outdoor coil, filters and fan wheel before and after

The outdoor coil fins had a layer of dust, the filters had dust caked on in sheets, and the blower wheel had black dust in its grooves. I sprayed cleaning foam over the whole evaporator coil so it could lift the dust before rinsing with water.

Arm, the technician, was responsible for and carried out this job.
