A/C Re-New has been successfully used for many years to improve the performance of air conditioning systems. A/C Re-New provides significant savings in energy use, quiets noisy systems, extends the life of systems, and resolves sticking reversing valves and TEVs due to friction. It is a lubricant that blends with the system’s oil, lasting for the life of the equipment, or until the oil is changed. In recent years, A/C Re-New has been successfully used to aid in existing oil migration when retrofitting an R-22 air conditioning system with a near drop-in refrigerant; examples include R-427A and R-407C and others. A/C Re-New not only helps with oil return at retrofit, but also comprehensively renews the air conditioner by reducing friction in the compressor (lowers amp draw), quiets the system and can aid in sticking flow control valves because of friction due to years of service.
