No, R12 Freon or R134 are refrigerants. They are used to cool the vehicle and have nothing whatsoever to do with heating the vehicle. That is done by hot coolant flowing through the heater core.
(Edit by JTM): I don't think Gerald C. thought this 1 through. While you don't need refrigerant to heat a car, try getting someone to let the refrigerant out of your car (or if your car has a sizable leak) & see what happens when winter gets here. The a/c refrigerant is circulated throughout the system to dry the windshield & windows off along with the heat from the engine. Without refrigerant in the system you'll be wiping a small hole in the windshield every few minutes so you can see what's in front of you. A somewhat dangerous practice. So, while you may not need it for heat, you'll definitely need it for defrosting. Most people don't even realize the a/c compressor is running when they turn the setting switch to "DEF". So, if your cars A/C doesn't work like mine did last winter, hopefully you'll have a friend who can help you fix it before it gets cold. Hope this helps.

Yes, the heat pump (in the heating mode) is like an air conditioner in reverse. It cools the outside air and heats the room air. Of course, you need Freon to do this heat-transfer process.
In order to buy freon you need a license, therefore you shouldn't attempt to add freon. Call a contractor to service your unit.
No, Freon is a "Refrigerant". It is compressed and then run through a heat exchanger where it expands and absorbs heat from the air that is being blown into the car. Coolant (Ethylene Glycol) only carries heat from one place (the engine) to another (The radiator).
On all years, makes and models you will need to go to any automotive a/c repair shop and have them reclaim this for you.... (Do not just let it out in the atmosphere this is illegal)....... Depending of if your have R-12 freon or R134A freon you can buy the R134a freon at any auto parts store but you need to be licensed to buy R-12 freon.........
Yes a heat pump reverses the function of an air conditioner. Like any refrigerant system if a Technician says "it needs Freon", make sure the leak is repaired first.
the air coming from the vent is warm
No.
yes but you need to how much freon if may not be cost effective. Plus you need to know if it is the same type of freon.
The exact amount of Freon that needs to be added to a Kia Optima is unknown. This is because if Freon is needed there may be a leak and the car will need to be taken to a mechanic.
Compressor not running?Heater control in heat position?
where do u put freon in a smart cAR 2009
Freon is odorless; you cannot smell it.
