What Can I Add To R22 System?

What can I add to R22 system? Substitutes for R22 in air conditioning systems and heat pumps

  • R407C as substitute for R22.
  • R410A as substitute for R22.
  • R417A/417B/422D/438A as substitutes for R22.
  • R427A as a substitute for R22.
  • R32 as substitute for R22.
  • What happens if you mix R22 and R-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. Replacing the condenser, compressor, evaporator and refrigerant lines. Evacuating the entire unit (i.e. vacuuming out all refrigerant)

    Can you mix AC refrigerants?

    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.

    Which freon can you mix with 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.

    What refrigerants are compatible with R22?

    However, units made after 2010 can use R22 alternatives such as R410A, R134A, R407C, and R407A. These refrigerants cool just as effectively as R22 without the ozone depleting features, and they have an acceptable Global Warming Potential (GWP).

    Can you mix R22 freon with 410a Freon?

    You can do it. You can mix R-22 and R-410a refrigerant in the same system.


    What happens if you mix car refrigerants?

    In short: no, it's not a good idea to mix different automotive air conditioning refrigerants. Your vehicle's HVAC system is designed for a specific kind of refrigerant, so adding another kind may cause the system to become damaged.


    What happens if you mix R22 with MO99?

    Mixing refrigerants is never recommended. However, based on the similar operating conditions of Freon™ MO99 and R-22, system damange would not be expected.


    Can you mix r134 with R22?

    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. But when mixing an alternative refrigerant with R-22, there's no pressure-temperature chart you can refer to.


    Can I mix R417a with R22?

    Yes you can replace R22 with R417a but you cannot mix refrigerants.


    How much R22 is in a 3 ton unit?

    The amount of cooling for your system can be estimated in the range of 2 to 4 pounds per ton. The 3-ton AC or Heat Pump with a 35 foot lineset will need a total of about 12 pounds of refrigerant.


    What is the most expensive Freon?

    At this moment, R-22 refrigerant is one of the most expensive gases on the market. The cost for a standard tank of R-22 was around $450 in 2015. In 2016, a similar 30-pound tank is over $500-$600. It is the sharpest price increase we've seen!


    Can you add R407C to R22?

    Mixing R22 with R407C

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


    Can you top off R22 with 427A?

    Can I top off with Forane® 427A? Yes, you can top off with liquid Forane® 427A if the system has already been retrofitted with Forane® 427A and leaks occur. The charge should be within specification. If a large portion of the charge has leaked, it is best to recover the remaining charge and weigh in a new charge.


    Can you buy R22 refrigerant?

    Many homeowners have been told that R22 is now illegal, and they have to change their HVAC not to be at odds with the law. That is false. R22 refrigerant is illegal to import and manufacturer in the U.S. But it's not illegal for anyone to buy R22 freon. And it's not illegal to sell it IF you have a license.


    How much is a pound of R-22 today?

    The cost of R-22 per pound is $20 to $50 when purchased wholesale by your HVAC specialist. However, when you call on a repair team to replace R-22, expect your bill to run from $90 to $150 per pound for installation.


    Can I use the same gauges for R22 and R410A?

    R-22 and R-410A, while intended for the same type of appli- cations, are indeed very different refrigerants. This also explains why many of the tools, accessories and components used for R-22 cannot be used with R-410A. Pressure gauges and hoses need to be rated for the higher pressures, or they can be damaged.


    What cools better R22 or R410A?

    Improved efficiency: R410A is able to absorb and release heat better than R22, making it more energy efficient. Plus, because it's more fluid in temperature changing abilities, it does a better job heating or cooling your house quickly.


    Can I use 410A coil with R22 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 I mix R134a with R12?

    As previously stated, R12 systems usually use mineral oil, which is incompatible with R134a. When R134a comes into contact with mineral oil, it can hinder the oil from returning to the compressor, or possibly reduce heat transfer.


    Can you replace R-22 with MO99?

    Retrofitting. For most R-22 systems, when retrofitting to Freon™ MO99, all you need to do is recover the R-22, replace critical seals, charge refrigerant, restart and monitor for leaks, label the system with a Freon™ MO99 retrofit label, and you're done. R-22 replacement can't get any easier.


    How do you convert R-22 to MO99?

  • Establish baseline performance with existing refrigerant. (
  • Remove all the old (R22 or other) refrigerant from the system into a recovery cylinder.
  • Replace the filter drier and critical elastomeric seals/gaskets.
  • Evacuate system and check for leaks.

  • Is MO99 the same as R-22?

    Freon™ MO99 is the closest match to R-22 of all "no oil change" replacement refrigerants. MO99 is compatible with mineral oil and POE oil providing a quick, cost-effective R-22 replacement, and can be topped off during service without removing the entire refrigerant charge.


    What happens if you put R134a in a R22 system?

    Using R134a in Systems Designed for R22

    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 swells the rubber components in the refrigeration system and causes leaks.
