Ventilation & Climate System Cleaning
That musty smell when the fan kicks on has a specific cause.
If your car smells fine sitting still but musty the moment you turn the fan on, the odour is coming from your ventilation system, not your interior. The cause is condensation on the air conditioning evaporator, which stays damp in a dark enclosed space and grows mould and bacteria on its surface. Every time the blower runs, air passes over that growth and carries the smell into the cabin, which is why cleaning your carpets never fixes it. Our treatment addresses the actual source: vents and ducts are cleared, the system is treated with an antibacterial application that reaches the evaporator, and where the odour is severe we follow with an ozone cycle run through the ventilation system to sterilize the full duct path. We will also flag a clogged cabin air filter, which is a cheap part that traps moisture and dust and is genuinely one of the most neglected items on any vehicle.
Our Ventilation Treatment
Stage I: Diagnose the Source
We confirm the smell is ventilation-based rather than interior contamination, and check the cabin air filter condition.
Stage II: Treat the System
Vents and ducts are cleared and an antibacterial treatment is circulated to reach the evaporator surface where the growth actually lives.
Stage III: Ozone Follow-Up if Needed
For severe cases, an ozone cycle is run with the ventilation on so treated air sterilizes the entire duct path.
