Our units cannot be charged with any type of refrigerant other than that listed on the name plate. There are a few reasons for this being:

In the example of R22 to R410a

  • The pipe is not rated at higher pressures of R410a
  • The oil in the compressor is not compatible with R410a
  • The system has not been designed to run with anything other than R22

R410a to R32

  • The system has not been designed to have a mildly flammable refrigerant
  • The oil is different in the compressor
  • The compressor has not been registered as part of the regulations

R410, R32 or R22 to a hydrocarbon

  • The system has not been designed to run with a flammable A2 class refrigerant
  • The product has not been registered to run with any other refrigerant other than what is stated on the name plate
  • Our service agents aren’t trained in to use of hydrocarbons

According to Airah, the following should apply




If our field teams or any other agent comes across a system that has been retrofitted, we have instructed them to instruct the customer that  the customer needs to return the unit to its designed condition before working on the product
