Can I use a 410A evaporator 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.
Can a R-22 compressor use R410A?
No. You can’t do that. It probably wouldn’t work. Even though you put a compressor in there that’s R410A, the rest of condenser probably isn’t tested and rated for operating at R410A pressures because R410A has to operate at a higher pressure.
How do I retrofit R-22 to R410A?
What does converting to R-410A entail?
- Evacuate the entire AC (vacuum out all R-22 refrigerant)
- Flush out any trace of R-22 then wait for the system to dry completely.
- Replace the compressor, accumulator and expansion valve with ones that can handle the higher temperature and pressure of R-410A refrigerant.
What happens if you mix R-22 and 410A?
The answer: No. Putting R-410A refrigerant into an AC unit that was designed to use R-22 will cause the unit to die soon after it tries to run.
What is the best replacement for R-22 refrigerant?
R-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.
Can I replace just my AC condenser?
Your Condenser Unit Could Solely Be to Blame for a Broken AC A common question we get is if you can replace just the condenser. The short answer is yes, you can. Some technicians often do in some cases. Perhaps if you have a newer system and the damage occurred due to outside forces, such as inclement weather.
How do I know if I have R-22 or 410A?
To know which type of refrigerant your air conditioner uses, take a look at the label on the compressor unit outside. It’ll clearly tell you which type of refrigerant the unit uses. The newer type is R-410A, and the older type that I’ve been talking about is R-22, also identified as HCFC-22.
Can a 410A condenser be installed on a R22 coil?
There is no reason to believe that the 410a condenser only install will have more problems, be less effective at cooling or will not last as long with or with out a matched coil. Why Does a r410a Condenser work on a R22 evaporator coil?
Which is more likely to leak refrigerant R22 or R410a?
R22 coils are made from copper which are more likely to leak refrigerant than the R410a coil. Your particular unit is a heat pump and because of the reversed refrigeration process where high pressure is exposed to the evaporator coil (which does not happen in an air conditioner) you have a greater chance of coil failure.
Can you mix R-410A and R-22 heat pump?
You should never use an R-22 evaporator coil with an R-410a outdoor unit if the outdoor unit is a HEAT PUMP. You should never reuse an R-22 evaporator coil if tin and antimony were used in the brazing process. By the way, if you find a coil like this it will be ancient. Manufacturers stopped using this process in the early 1950’s.
Is the refrigerant good for a R22 coil?
Hopefully The tech cleaned the coil and line set prior to soldering in the new condenser. Other than knowing the charge of R410A refrigerant in the condenser will not be adequate for the R22 coil and be ready to add more, the system should function properly.

Your particular unit is a heat pump and because of the reversed refrigeration process where high pressure is exposed to the evaporator coil (which does not happen in an air conditioner) you have a greater chance of coil failure.
What are the running pressures on a R410A condenser?
Moreover, the operating, running pressures are closer to 165 PSI at the coil. Based on a 9 year history of this practice and 2 dozen plus warehouse test mutts, we know conclusively that there is no more risk of cross-contamination from R22 to the new 410a with a condenser only change out than if you were changing the evap coil too.
What is the temp of a R22 evaporator coil?
The condenser tag states r22 and the evap coil/air handler calls for 410a and I am only getting a 14 degree split. What is the indoor wet bulb temp. What is the dry bulb temp at the condenser coil. What is the indoor temperature. What are the high and low refrigerant pressures.
