My dealership has offered me a Deodorising service of my Air Conditioner next week when it goes in for a 60,000km Service.
I knocked them back on the offer as I think it is a scam, I had it done once before in my 2013 CRV and the nice clean smell lasted about a week.

Outside of making the aircon smell nice for a week at most, is there any other advantage to having it done?

If it is some kind of germicide and help prohibit mold growth you might consider it.
I'm wondering now--- how they do it.
Do they spray something into the system, a aerosol ? And where do they spray this?
Can we buy this product from the parts dept and do it ourselves?

See what you can find out and get back to us.
I'd do it to my AC System--It is prone to bacteria growth from the humidity.

Here "downunder" we can buy a Deodoriser from Auto shops ... http://search.supercheapauto.com.au/search?w=air%20conditioner%20cleaner.

I think I will check this out with an Auto Air Conditioning specialist just to be certain.
I checked YOUTUBE and watches people use sprays like Lysol--
which deodorizes and has bacteria killing stuff.
You spray it into the outside air intake while the AC is running
and bringing in fresh air---not recirculate.
Also remove the Cabin Air Filter--BEFORE you do this so the spray gets to the vents.
If you do use a spay like Lysol--remember they do come in different sents
so get a nice smelling one.

$45.00AUD for a Cabin Filter and $90.00AUD for the Deodoriser & Bacteria Treatment that comes in a small container that has a fitting to lock down the spray activator to set it off like a "bomb" inside the car.
No Thanks I'll do it myself.

First post! Just got a used CRV, came to ask a different question, but thought I'd offer an answer before I ask a question. :)

Mold grows between the fins of the AC evaporator coil when organic matter is allowed to get into the coil. Mostly this would be pollen and dust. The way to prevent the odor is to replace the cabin air filter often. Replace it after pollen season is just finished so you don't carry a load of pollen around in the filter all year, because mold will grow on it in the filter.

If the coil is already smelly, then an ozone generator can be used to kill any germs anywhere in the car. Ozone doesn't just kill germs, it oxidizes germs, meaning it dissolves them into water and CO2. Ozone is made an even stronger germicide when the surface to be sanitized is wet, so it is the perfect way to clean the AC evap coil, which is always wet. Disaster recovery professionals use O3 generators to rid the wet house of mold after a fire or flood, even in carpets.

Get a powerful ozone machine. I have one that makes 6mg per hour. They are cheap now, like $70.

Run the engine and air conditioning system on high with the windows down on a humid day. The humidity will keep the coil wet so the ozone works better. Use a wet finger under the dash to locate the air intake when the fan is on high. The air movement will cool your wet finger and indicate the direction of airflow. Aim the output of the O3 machine into the AC intake. Turn the O3 machine to highest output level and let it work for a while. I would give it at least 30 minutes. Then shut off the O3 machine, open the doors to let O3 spill out (heavier than air) and you're done. Ozone breaks down into O2 in 6 minutes. Don't sit in the car while running the O3 machine.

You could also close the windows and close the recirculation to get even higher concentration of O3, but I think the wet coil helps.
You can run the O3 machine in the car while the carpets and upholstery are drying after cleaning them. It will also kill bugs in the car if you run it long enough.

Hope this helps!

Doesn't seem to be a good idea to me.

The information even comes from the USA & Canada.

Definitely not a good idea to sit in the car with it running or to hop in immediately after it finishes. It would most certainly be bad for you. But it only takes a few minutes to air the car out after you finish, and O3 will naturally break down into O2 within 10 minutes or so.
Did the following not get your attention: "Further, ozone is not effective for killing bacteria or mould in materials such as air conditioning duct lining and ceiling tiles."

Exposure to ozone

Can cause eye, nose, throat and lung irritation, cough and shortness of breath.
May exacerbate chronic respiratory diseases such as asthma.
Is likely to increase hospital admissions and emergency room visits for respiratory disease.
Can also adversely affect indoor plants, and damage materials such as rubber, electrical wire coatings, and fabrics.

The original link I posted to facts about Ozone Generators makes them sound more & more like snake oil to me.

I dont know about all of what they claim will be damaged by ozone. I'm sure if it stays in contact long enough (a very long time), something may be adversely affected. And it most certainly will kill mold and bacteria in soft material provided you have a high enough concentration. As far as exposure goes, like I said before, you cant occupy the space while you are using it. It will dissipate pretty quickly after the generator is turned off.

Here there is an enzyme bathroom cleaner that can be purchased locally at the commercial cleaning supply house. It is a white liguid to be sprayed on bathroom surfaces. It kills germs and odors and leaves a pleasant smell while not staining or leaving a noticeable residue. When I change the cabin air filter, I spray some inside the plenum, then run the A/C for a bit. Works great, no overwhelming cancer-causing cover-up air freshener smell.
