LG wall splits (including Dual Inverter) are common in apartments. Thin indoor plastic and tight coil gaps mean cheap high-pressure washes bend fins easily — we do not do that. Gold-fin outdoor coils still clog with sand; coating is not a substitute for rinsing.
We are an independent AC service company, not an authorised service centre of LG. Warranty work that must go through the brand should go through the brand. We repair and service the machine as an independent technician.

Thin fins: chemical foam + gentle rinse, not a petrol-station jet.
