Your AC’s air filter, blower wheel, evaporator coil, and condenser coil need to be cleaned before you “charge” your unit with more refrigerant. Adding more refrigerant to a unit with dirty parts can damage the AC. Putting the wrong refrigerant in your unit can cause combustion, injury, and property damage. Check your AC manufacturer’s operating guide to find out which refrigerant your unit needs. If you don’t have the operating guide, check the electrical control box or the unit’s cabinet for the information. The 2 most common refrigerants are R-22 and R410A.  R-22 is mostly used in older units and is slowly being phased out because it is an ozone depleting material.  If your AC is leaking R-22, it’s important that you get the problem fixed as soon as possible. Since R-22 is in the process of being discontinued, the price for it has skyrocketed and will only continue to get higher. Wear safety goggles and thick gloves when handling Freon. Never directly inhale any refrigerant; doing so can lead to sudden death. Some refrigerants are particularly hazardous and require respiratory protection -- read the packaging for more information.  If you get Freon on your skin, rinse the area with water and seek medical treatment immediately. R-717 and R-764 refrigerants are extremely irritating to the eyes and lungs. R-717 is flammable. Handle with caution. Liquid Freon will automatically seek the coldest area of an enclosed AC unit between the furnace coil and the outside condensing unit. When outdoor temperatures are under 55°F, the coldest area of your system will most likely be the outside unit. The Freon will not behave properly in these conditions.
