Can I use a R-22 evaporator coil to R410A?
Almost all new evaporator coils can be used with either an R-22 system or an R-410a system. They cannot, however, have been used with both types of gas: once you have released gas into the evaporator coil it becomes dedicated to that type of gas and cannot later be used with a different type of gas.
How do I retrofit R-22 to R410A?
If you’re going to convert from R22 to R410A refrigerant, the best thing to do would be to flush the lines you have, and put in units, an air handler and condenser that is meant to use R410A. R410A and R-22 are just so different that doing stuff like you want to do won’t really work.
Can you put a 410A condenser on a R-22 coil?
The answer is an undeniable and indisputable yes. Though you may hear several opinions to the contrary, we know from experience that it will cool equally as well as the old unit. When tuned properly, it will produce at least as cold of air as the R22 counter part being replaced.
Can you use R-22 in a 410A air handler?
You cannot just switch refrigerants because R410-A and R-22 have different chemical properties.
Can I replace R22 condenser with R407C condenser?
The following is a set of general guidelines to assist in the replacement of R22 condensing units with equivalent R407C units. They are not meant to replace any existing relevant standards or recommended good practice.
Do they still make R22 coils?
The U.S. government has placed restrictions on R22 and has issued the requirement that R22 refrigerant must be eliminated from use in cooling systems by the year 2020. At this point, R22 will no longer be manufactured and cannot be used as a refrigerant in new air conditioning systems.
Is there a substitute for R-22 refrigerant?
R410A as substitute for R22. In addition to R407C, the near-azeotropic mixture listed by ASHRAE as R410A is available and widely used for medium-sized capacities in air conditioning and heat pump applications.
What refrigerant is compatible with R-22?
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.
