A/C on or off during winter?
I'm confused if I should turn on A/C during winter. I changed the setting, so that only warm air is coming out. What are the benefits or disadvantages using A/C during winter? Also, when the engine is off, the air is not as warm as the engine is on, what should I do?

Time to time you have to turn it on for 5 -10 min. to oil de gaskets and avoid the further leaks.

Mine is always on - the A/C doesnt cool the air anymore automatically (if ur talking about the automatic A/C not the manual of the CS) if the outside temperature is below (if i remember right) 5°C but it always drys the air in the car (esp. important in the winter with all the snow (so water in the end) at ur shoes and clothes...).

Did you know that the AC is used when the ventilation is set to defrost?? The AC is used to dry out the air.

Leave it on. It acts as a dehumidifier in the winter.

Leave the system to keep the climate as constant as possible. Heat, chill, demist, dehumidify, etc. I'm in quite a humid environment, the full climate control keeps a dry and smell free vehicle. |

"A/C" as "Air Conditioning" can be used for the purpose in any season. The "Air Cooling" function is fool proof (in modern cars, at least?) and reportedly just does not work in cold weather even if it is "on": regardless automatic climate or not. See the user manual for usage suggestions and precautions (if any). Regarding dehumidifying. Those who not only went to school but learned there as well should be aware (from thermodynamics basics?) that it's a side effect of cooling: the water is being removed from the air by condensing on the cold radiator that's cooling the air (you can find the water underneath the vehicle afterwards). No cooling = no drying. This simple. (A disclaimer: the refrigerating air cooling is meant, not the evaporative cooling which wouldn't dehumidify, just the opposite.) Therefore it's doubtful if air cooling can be used for defrosting the windows but you can try as the manual suggests. It should be safe to keep the air cooling on all the time if you don't need that engine power consumed for it and neither mind some fuel consumption it takes, apparently. Otherwise mind your need for the function and consider turning it off for ultimate efficiency when it's not needed. If it's the dehumidifying you are after (often in cool weather?) and cooling is an unwanted side effect use the air heating function to compensate (and take some heat which might be extra sometimes off the engine meanwhile) when using air conditioning in manual mode. |

Unless you want your car to smell like a used jock strap, AC is always on. Despite popular belief, ac doesn't cause smelly vents. Turning them off causes it especially in winter, when moisture from the snow and rain adds to the moisture in your car cabin.

Air conditioning still works when it’s cold, just as a heat exchanger would. It is designed to run through all seasons and, yes it does have a an affect of being a dehumidifier, especially when the cabin is damp from passengers. Auto manufacturers set them up that way, so,seals and gaskets don’t dry out. |

Plus the HVAC system is designed to protect itself in colder temperatures. Will switch off the compressor if the evaporator temperature drops below ~3C. So we don't need to intervene at all. We get the dehumidifying function to the lowest possible temperature possible in a car's HVAC system. |

I see the HVAC system for what it is, "climate control", not simply do we need A/C function switched on. I can understand users in sub zero temperatures switching the A/C function off, but not for guys like me, where temperature swings are quite large during winter with high humidity. I need A/C more in winter for dehumidifying than I need it in summer for cooling. Hence why I simply leave the climate control in full auto mode, no misting, fogging, or damp, in the car. |
