As the warmer weather has arrived (for how long who knows...) I decided to switch the air con on for the first time since I purchased my FN2 CTR GT. When I first put it on there is a really stale smell - after a few minutes this does seem to go away and the air is chilled but again next time I put it on the same happens.

Is this some sort of filter or something that needs cleaning? My old ctr didnt have air con so I'm not sure about this!

Thanks

As the Air con has not been run for some time, mould and stuff can grow within the filters.

Try changing the cabin air filter, there are also other on this forum that have purchased a spray that they spray into the air vents.

Best cure is to use the air con all the time - it also helps in cold weather too ;)

When I picked up my Civic, it smelled like something had died in it and then been left to rot until the car was sold. I mentioned this to the dealers, and they changed the cabin filter for me. On the 4 hour drive home, the smell gradually disappeared, but didn't go away completely. The solution for me was to set off one of those air con cleaners from Comma. It worked a treat, and my car no longer has the smell of death in it.

Halfords | Comma Aircon Cleaner

An examples of a spray, you can get others.
Some you spray into the vents, others you set off in the car, close all the windows, doors, and set the air to internal circulation, and leave the car and air con running for a few mins (dont be sat in the car when you set it off, lol).

But best thing is to leave the air con on all the time (perhaps not so good for fuel), but beats smell of feat or mould!

As said by others - the filter is probably 'shot', so I'd replace it ...

Leave the AC on all the time - even in Winter - fuel consumption is not measurable ...

There is always a funny smell from all aircon devices once you first turn it on, its worse if you had it on the day before. Its just moisture and its pretty normal. If it was the gas then the aircon wouldn't cool, so I wouldn't get it re-gased. You may also find a pool of water under the car if you have it on for a while, this is also normal. I've owned cars with aircon for the past 12+ years and they are all the same.

You must remember to turn on the aircon at least once a month for it to keep working correctly and to stop it drying out. Honda recommend using the aircon once a week, this may be overkill!

Leaving it on Auto should be the preferred option, but it is so damn noisy at low speeds, and downright intrusive when sitting stationary!! :eek:
What i do is switch on the air con on my drive to or from work once a week during the Winter months. This is a 9 mile 10-15 minute drive, and will be more than enough to stop any nasty bacteria from forming.

I agree that any negative effect on fuel consumption due to having the air con running constantly, will be minimal.

Both AC systems in my Accord and my Primera failed after I had left them off for some time.

After the Accord was regassed, it was always on AUTO, and I'm doing the same with the Civic.

How long a period are you talking, and how old were your cars at that time?

Im just trying to get a better undestanding of the problem. :)

Excuse my ignorance, but why is a smell related to a regas?

That would sound so obvious in a different context :D
I think some people mean AC service... regas, pollun filter etc.

Quite...:)

However unless I'm missing something, the original post was about a smell, so don't get the suggestion of a regas just for the sake of it?

The issue is bacteria buildup in the filter and ducting.
You can change the filter.... need a sanitizer bomb for the ductwork though.
Best to leave the AC on anyway or it will pack up if it aint used.
Regas only helps with the temps. :thumbsup:
