Can you mix R22 and 134a Freon?
R-22 systems are typically about 300 psi maximum. If you add R-22 to an R-134a system, you will not get close to the rated cooling capacity of the A/C system. In conclusion, do not mix R-22 with R-134a refrigerants, you will ruin the charge, and possibly seriously damage or destroy your A/C system.
Can you mix R22 and R410A together?
R-22 and R-410a are both refrigerants, true. They can both be used in air conditioners or heat pumps to cool your home during summer. ... You should never, ever try to mix them in the same system, or use them in a system not rated specifically for that kind of refrigerant.
Is it illegal to mix refrigerants?
Due to the destructive effects of the compositions of refrigerants on the environment, the EPA has banned the use of certain refrigerants altogether. These banned refrigerants were to be replaced with new ones, and mixing refrigerants became totally illegal.19-Oct-2017
Can you mix freon types?
In short, the answer is, "No!" Automotive refrigerants are volatile compounds that can have a negative effect on the environment. Combining them can have adverse effects, and cause damage to your car's A/C system.27-Nov-2018
Can I mix R22 with R290?
Because R290 has similar saturated pressure-temperature characteristics and volumetric refrigerating capacity as R22, is miscible with the oils typically used in R22 compressors, is relatively cheap and is reported to yield favourable efficiency, it is often deemed as a desirable option to use in existing R22 systems.21-Aug-2016
Can you mix R422D with R22?
Re: Conflicting info regarding R22 and R422D R422D is a so called drop in for R22. You must remove the R22 and replace the whole charge with the R422D. In theory R422D runs OK with the original Mineral oil charge in the compressor and simply replacing the gas is all that's required. ( Never mix refrigerants !.)21-Aug-2015
Can I use 410A coil with R-22 condenser?
Mechanically, R-410A operates at higher pressures, lower temperatures, and does not mix with R-22 systems. In order to use a R-410A evaporator coil in an R-22 system, the evaporator coil, condenser, line-sets and refrigerant must all be converted to R-410A specifications.26-Sept-2017

PHASING OUT R-22 REFRIGERANTS
Because R-22 depletes the ozone layer, production and import of the refrigerant was further limited in 2010. According to the Environmental Protection Agency (EPA), in 2020, R-22 will no longer be produced or imported. After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available.
WHAT CAN HAPPEN TO MY SYSTEM IF I MIX REFRIGERANTS?
Operating pressures and temperatures will definitely change for the worse. The different types of refrigerants are not meant to be mixed. The refrigerant charge must be optimized by using the refrigerant’s respective pressure-temperature chart.
IS IT ILLEGAL TO MIX REFRIGERANTS?
The EPA isn’t likely to come banging on your door for mixing refrigerants, but even if they don’t, the environment is already under enough pressure with the use of refrigerants in their purest form. Our environment doesn’t need an unscrupulous contractor or technician mixing refrigerants.
WHY WOULD A CONTRACTOR MIX REFRIGERANTS?
The answer is cost. A 30 lb jug or R-22 can cost 3-4 times that of a replacement refrigerant. The contractor or technician that doesn’t care about you, your equipment, or the environment will “top-off” a system and get away before the homeowner ever notices the losses in system capacity or the damage being done to their equipment.
