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.
What would happens if you put R22 in a 410A system?
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 . ... Replacing the condenser, compressor, evaporator and refrigerant lines. Evacuating the entire unit (i.e. vacuuming out all refrigerant)
How do I retrofit R22 to R410A?
- 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 refrigerant can you mix with R22?
- Mixing R22 with R407C or any other refrigerant.
- According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.
What happens if you mix AC refrigerant?
Mixing refrigerants can have an adverse effect on air conditioning and refrigeration systems, resulting in reduced efficiency, performance, and longevity. And it can create a safety hazard for the technician who may not know exactly what type of refrigerant a system may contain.
How much does it cost to convert R22 to R410A?
The average R22 to R410A conversion cost is $2,000 including materials and labor. Homeowners spend an average of $400 per 25 pounds of R410A refrigerant. You can save money and replace your air conditioner with a single-stage unit for $1,500 instead of converting it.
How do you tell if you have R22 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.
What is the best replacement for R22?
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.
How do you add refrigerant to R22?
Pure refrigerants like R22 can be added in liquid or vapor states . If adding liquid into the suction like, throttle it in slowly to avoid slugging the compressor or diluting and washing out the compressor oil. After the charge has been set, avoid installing the gauges as part of regular service.
Is there a direct replacement for R22?
RS-44 is a direct drop-in replacement for R22 in ac applications in systems with a capillary as well as an expansion device. There is no need to change the lubricant since, as with all the RS series of refrigerants, RS-44 is compatible with mineral, alkyl benzene and POE oils.
Can I use a 410A condenser with R-22 coil?
Can I use an R410A condenser with an R22 air handler? No, you cannot . To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures.
What happens if you use the wrong refrigerant?

Can I add R134a to a R-22 system?
If you have a home or auto air conditioner designed to work with R22 refrigerant, and the system needs a recharge, a number of issues prevent the direct substitution of R134a. ... R134a has a lower thermal conductivity than R22, so an R134a system needs a larger heat exchanger.
Do I have to replace my R22 air conditioner?
The ban doesn’t require you to replace a functioning, R22 refrigerant AC or heat pump system. ... Even though OPTION 1 may sound like an easy fix, the price of R22 refrigerant is subject to shrinking supply. This may make R22 very expensive.
What is a drop in replacement for R22?
