Auto air conditioning systems built before 1995 use the refrigerant R-12 or (CFC-12), also referred to as Freon. The EPA determined that Freon was destroying the ozone layer and in 1995, all production ceased. Freon is now extremely expensive and difficult to find. PTAC offers a retrofit service that enables your A/C system to use the inexpensive R-134a refrigerant. The retrofit pays for itself in the cost savings on the refrigerant. What does the retrofit service include? • All retrofits are evaluated on a case-by-case basis. Different vehicles may require slightly different procedures. • We evacuate all R-12 and most of the existing refrigerant oils from the air conditioning system. • In some instances, certain parts, such as the O-rings, hoses, accumulator or receiver/dryer, must be replaced to assure compatibility with R-134a. • In addition, special fittings and labels must be placed on the vehicle to properly identify that it has been retrofitted.
