"When do we need to perform Chemical Wash"? Actually, it depends on the usage of your aircon units, if you have one unit's usage that is low, like 2-3 hours a day compared to another unit which is high frequency between 8-10 hours a day, this high frequency unit will definitely get dirty faster than the low usage one, so it will need a chemical wash much sooner. Usually takes about 30 minutes to an hour duration per unit of aircon to be chemical washed, depending on the brand, model & BTU size of the aircon units.

Benefits of Aircon Chemical Wash

Why go for a chemical wash? A chemical air conditioning wash is suitable for aircon units that faced issues like gel-like residue formed overtime that's filling up the fins and gaps of cooling coil, decreased air-flow power, blower fans dust accumulation, weak fan power etc. Because chemical aircon wash flushes out the coil, clean up the interior where possible without dismounting the full unit. It’s also a great way to ensure your aircon unit doesn’t start smelling, stop cooling the air or starts to leak. If you’re noticing any of these issues, a chemical aircon wash is the right service for you! Compare aircon chemical wash to chemical overhaul here.
