I’ve only ever owned 3 vehicles but even the cars I’ve borrowed or rented the feet heat always sucks it just blows it straight forward back into the engine rather than down at my feet, I always have to shove my feet directly up into the dash to get heat, is there a reason we can’t adjust the feet vent or any other solution?
Automotive HVAC engineer here. At least where I work, these floor ducts are fixed and do not have positionable vents like the ones on the dash. The nozzles on the floor ducts are ideally aimed to hit both pedals and the dead pedal. You car might not have great floor duct aiming.
Generally speaking, floor aiming isn’t super important for cabin comfort. These ducts are supposed to be used for heating. The gentle heat coming from these ducts will radiate throughout the cabin.
If your car has automatic climate control, use it. The system will know what to do based on the current coolant temperature and the temperature outside. Leave it at 72F like you would your house.
When you come home on a hot day and you turn on your home’s AC, you don’t drop it down to 60F. You leave around 72 and the AC cools it down. Your car is the same way. Don’t jack up or down the set point hoping to cool or warm the cabin better.
Any tips to save gas during winter? Should I just leave the settings on auto and call it a day ?
