How do you re gas your air conditioning on your ford focus?

Answer 1

You recharge an A/C system by adding freon through the Low side port. Look for the L on the cap. Never recharge on the high side. Too much pressure on this side and your freon can might explode.

OK, once again it's not freon! it's R134a refrigerant that should be used to fill your car system. Many people call it freon but you need the r134a refrigerant( and oil, too). Anyway, freon cans are only available to certified mechanics in most states now.
