Honda Accord Cooling Coil — Clean or Replace?
Musty smell from Honda Accord vents? Evaporator cleaning guide, costs and when full replacement is necessary in Malaysia.

Accord evaporator (cooling coil) accumulates moisture and biofilm over time, causing musty odours. Refrigerant leaks from the evaporator are harder to detect than condenser leaks.
Evaporator care and replacement
Preventive: use genuine Honda cabin filter and dry the coil by running fan-only for 5 minutes before shutdown. Curative: evaporator sanitise spray (RM80–130). If refrigerant keeps being lost without a condenser leak, pressure-test the evaporator. Replacement involves dashboard removal — a major job at RM900–1,500.
