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.
Call your tech back and ask him to put 3LB of 134a and 15.5oz of 404a and your unit will work better than ever before make sure he changes the oild to mobil 5w30:grin2:
NO EPA say NO
Anyone who Know anthing about HVAC knows thats WRONG.
A Tech like that should not be allowed to work in HVAC

Dude was a dumbass.
It's sad companies send guys like that out to run service.
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.
You gotta be kidding!!!!!!!!!!
that guy deserves a punch in the throat ...
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 temp
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!!
