    Mixing R22 and R410a

    I had a tech come and service my AC the other day and he put R410 refrigerant in in my R22 system. He said you can mix up to 20% as long as you keep the pressures in line. Is this true ? He said the real problem is the oils and when you add refrigerant you are not adding oil. Is that right ? Sounds fishy to me. Thanks in advance for your thoughts.

    He needs to recover that charge. Then evac and recharge the unit properly. Don't run the system until it's repaired. That company will have to pay to have that refrigerant destroyed.

    With those two common gases, he would be in the wrong.

    But EPA does allow you to mix,if and only if you can't get your hands on the original refrigerant.

    One way to outthink people is to make them think you think. They'll think you're not really thinking what you're trying to get them to think you think...........

    OK I now understand what you thinking, however I don't believe in fact I thought EPA forbid what I call field mixing.

    Are you say EPA allows this??? is so could you show that reg.

    I would like to see reg and be able to show quote it to an EPA Rep for clarification. This would be be nice Infor to have on hand.

    Thanks

    I thought ASHRAE was the entity in charge of approving refrigerants blends. as far as I know EPA is more or less another layer of government bureaucrats gathered under the pretenses of protecting the environment.
