Smelly aircon

[tonymy01]

Yes, but as it is cool inside the system, when you turn off the car, the cool interior surface of the air con assembly draws in moisture, which sits for quite a while and a perfect environment to harbour mould/mildew. If you turn off the a/c a few mins before stopping the car (but not the total system) then the warmer air helps bring up the system to outside air temperature so when the car is turned off, moisture won't accumulate on the interior surface of all the aircon system.

Start the car. Turn on the heating at the highest fan level and highest temperature. Leave all the windows down. Leave it all running for 10-15 minutes.

I've had my car for over 6 months now and it's due for its 15k service. For the last few weeks I've been noticing that the aircon is starting to smell upon startup for around 30-60 sec. I asked the service people and they're asking me for 99 dollars for an antibacterial spray. Do you know what can be the other reasons for this? Because for a spray... 99 dollars is abit too much.

Oh and they said it's because of the dead bugs building up in the filter.

Thoughts?

The heater core is after the evaporator. So how will this help?

I've had the same problem after 25,000km. I always try to turn the air-con off and max fan 1 min before I arrive at my destination (turning the heater up on a hot day really isn't ideal!) but couldn't prevent it.

I took our my cabin air filter behind the glove box then vacuum the accumulated rubbish and it seems to have helped significantly.
Maybe do the same or buy a new cabin filter.

quick google search, cabin filter costs around $35

Except buy a carbon-activated one, instead of a plain paper one.

The plain ones are just leaf catchers and nothing more.

True, and I find it genuinely makes a different in pollen reduction.
