I had my car serviced and I accidentally agreed to have some sort of service called "A/C Vent Mist Service" done. They described the service as cleaning your car's A/C vents and removing things that irritate your allergies and so on.
But after getting the bill I kind of regret having the service because it seems expensive and not worth the $80 cost (25 minutes totaling $55 and $25 parts).
What is "A/C Vent Mist Service"?
Is this service only needed for cars that have really bad smell maybe? my car is new so maybe I should have avoided it...
