Hi LKC0402,
The wisp of frosted air you noticed could be due to frosting/freezing of the evaporator.
Possible causes.
1. Temperature adjusted too cold.
2. External air mix, ie vents might have been turned to fresh air instead of recirculating. This might happen if you use Auto AC function and when the vents are turned to fresh automatically.
