, this refrigerant is a non-ozone-depleting HFC blend designed specifically to retro-fit existing R22 systems without requiring a complex oil change. For technicians and homeowners alike, buying R421A represents a practical balance between environmental responsibility and mechanical efficiency.
Another significant advantage that drives people to buy R421A is its compatibility with standard lubricants. Many HFC replacements require a total system flush to replace mineral oil with synthetic POE oil, a process that is both time-consuming and expensive. R421A is engineered to work effectively with the mineral or alkylbenzene oils already present in older R22 units. This "drop-in" capability makes it an attractive purchase for maintaining older residential and commercial air conditioning units, as it significantly lowers labor costs and system downtime. buy r421a refrigerant
