In order to add Freon to a car the car does not need to be running. However it is recommended that the car be turned on and the air conditioning be turned to the max setting in order to help distribute the Freon evenly. It is also important to make sure that the car’s engine is cool before adding Freon as adding it to a hot engine could cause damage.
When adding Freon it is important to follow the instructions that come with the Freon canister. Usually the Freon will need to be diluted with a lubricant before being added to the car. Once the Freon is added the air conditioning system should be turned on for a few minutes to help distribute the Freon evenly. After that the car can be turned off and the Freon will continue to circulate.
If the car does not have Freon already then it likely needs to have a Freon recharge. This can be done at most auto shops and only takes a few minutes. The cost of a Freon recharge will vary depending on the shop and the type of car but it is typically around $100.
