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.FEN

You gotta be kidding!!!!!!!!!!
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...........

So what if the epa allows you to mix? Are you serious? The 2 ref. couldn't be much more different. 2000 Posts and you never looked at a flash or saturation tempTwilly is my hero!

Is this guy crazy!!!!!!!!!!!
The oils are different, the pressures are different, and the copper used to make the coils is different. Never let this close to anyone you care about ever again.
We cannot even use the same gauges with these two refrigerants because of the differences. This is so crazy it is almost absurd!!
