Restore portable AC cooling. Clean the hidden condenser coil. No cost fix.

My decade old Haier roll-around portable A/C unit was not cooling properly. I needed it during renovation work due to very hot weather. Cleaning the filter did not help, and I needed to clean the hidden condenser coil which was caked with years of dust and debris. I'll show the viewer how to effectively clean the evaporator and condenser coils to restore efficient operation.  After this deep cleaning it works as good as new.
