Sunday Coil Cleaning #BERTLIFE
Subscribe to our Youtube channel
The customers recently had a very dirty evaporator coil cleaned by another company, but the float switch is still clogged. The unit hadn’t been running, as the person who cleaned the coil overflowed the drain and caused the float switch to trip.
Bert exposes the coil (and the other guy’s work ethic) and shows just how much soil buildup is still present. So, Bert walks us through his clean-in-place procedure.
He starts by laying down a drop cloth in the return. He then starts off his cleaning by vacuuming the loose soil off the coil’s surface. Gentle strokes will allow you to get a solid cleaning without damaging the coil.
To clean the coil in place, Bert uses the Refrigeration Technologies Viper Coil Cleaner aerosol. To use the aerosol in the can, spray it in a zigzag motion on the coil from top to bottom and allow it to dwell. The Viper Coil Cleaner is a self-rinse product, but Bert still rinses the product. He connects the shop vacuum to the drain and runs some water through the drain first. He rinses the coil itself in the opposite direction of airflow and from the inside out; to do that, he uses the SpeedClean CoilJet filled with water.
Bert is sure to finish strong by cleaning the work area and showing the customer some before and after photos. He also ends with a flourish by applying Refrigeration Technologies Pan & Drain Treatment, replacing the filter, and filling the trap. Once he confirms drainage, his job is complete.
