Not many think it is a good idea to run the a/c when temperatures outside are near freezing and the ground is covered by snow. However, running the a/c in the winter months does not cause any harm to the car’s heating and cooling system.
Does car AC work when its cold outside?
Your A/C refrigerant system is totally protected in cold temperatures.
What outside temp is too cold for AC?
Each air conditioner, regardless of model or brand, has the lowest temperature limit. The temperature must be below 60 degrees Fahrenheit. The unit’s inner coils will freeze. The lubricating fluid will thicken, and the unit will not function properly and may ultimately damage the air conditioner.

The ideal temperature should be 6 degrees Celsius or in old school money 42 degrees Fahrenheit. There are many motorists who still are using their air con incorrectly, leaving them hot and uncomfortable in the driver’s seat.
How cold should car AC be?
Drive the car with the A/C on “max”. With temperatures in the 70’s to 80’s Fahrenheit the outlet temperature should be around 35 to 48 degrees. Some cars made after 2014 use another refrigerant called R134yf, which is a synthetic HFO refrigerant and a successor to R134a for automotive air-conditioning applications.
Is 68 too cold for AC?
An AC unit is happiest creating space temperatures no lower than 68 degrees fahrenheit. … So you’ll still be hot and your thermostat limbo may result in a significant repair bill, or early death of your AC unit, which are definitely NOT great.

How can I make my car AC colder?
Turn the fan to its maximum speed and make sure the airflow is set to “outside” mode. Then, once you’ve forced out some of the humid, hot air that’s accumulated in the car, turn on the A/C and switch to “recirculate” airflow mode. Now you can set the A/C to “max cool.”
What happens if car AC is not used for long time?

How cold can R134a get?
It depends on the type of application, Freons like R134a has freezing point of up to -103°C and in most refrigeration purposes the user set temperature won’t be below -15°C .
