What is R-421A?

Choice™ R-421A is a non-ozone depleting, long term replacement for R-22 refrigerant. Requires no modification to AC / HP systems and is compatible with MO, AB, or POE lubricants. The only 2 component blend to replace R-22 and is within 1% of R-22 temperature / pressures.

What type of oil is used with R-421A refrigerant?

Remember this product as a lubricant which is compatible with basically any oil (Mineral, POE or AB) and the manufacturer claims no oil drain/change is required for any application for any application with less than 20 feet line or less than 20 feet drop in high between compressor and evaporator.

What is the difference between R22 and 407c?

The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.

Can you mix R22 and 407c?

Mixing R22 with R407C According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.

Is r421a a good refrigerant for mid temp systems?

Refrigerant Guys labs tested R421a on mid temp systems and found no particular problems. Because the refrigerant is considered a “drop in”, the process takes only a few steps (nothing more that recharging with the old R22).
