lol....My detector is broke. 4 customers today decided they should get 180* air from the vents 2 minutes after starting a car that was parked outside all night. Turns out they were serious.
Recalibration will be complete somewhere around my 4th glass of ruma coka. I just started #3.

It's people like that who keep you in a job, though. You know they aren't changing their own oil, and you know they can be upsold to recharging the flux capacitor for the winter months, too.
