For this course of to achieve success, a selected stage of refrigerant should be maintained. Subsequently, restoring the refrigerant to its optimum stage is finished by recharging the air con system.

TIP: You’ll typically hear air con refrigerant known as “Freon.” Freon, like Kleenex, is a model identify for a hydrochlorofluorocarbon (HCFC) refrigerant utilized in automotive AC methods for many years. It’s now banned by the Environmental Safety Company (EPA).
