Please forgive me for my ignorance but I am a Sheet Metal worker and only install about three to five residential systems a year on the side. I haven't installed a r410a system yet and have always used super heat to charge R 22 systems. Can I still use superheat for 410a.

Depends on if it has a TXV or not.. The installation manual for the system you are installing will explain exactly how to charge the system.
Make sure your gauges/hoses are the type to be used on a 410a system.

RUNDAWG is offering some good advice. Maybe you should look into getting R-410a certified . There are many areas with this refrigerant that you can put you and many others in danger. In fact if you install R-410a equipment without being certified your breaking the law.

There isn't any special EPA cert for R410A.

ESCO R-410a SAFETY CERTIFICATION is Proctored with a seminar , study guide and exam ,as well as equipment wholesalers requiring it for purchase of their equipment , EXAMPLE " US AIR CONDITIONING ITs part of the HVAC Excellence .. Mainstream offers a free R-410a exam by internet.

410-a has a safety course but you do not need it to buy 410-a.

Still not an EPA requirement. So no law broken if someone doesn't have it.
ESCO's Proctored exam. just means you pay more for it. Thats all.
It is not an EPA requirement.
While I believe people should take a course on it.
I'm not gonna lie to them and tell them they are breaking the law if they don't.

I was teaching R410A training just a while back. My presentation was about 300 slides. There are many similarities to R22 charging but also some key differences that affect the system long term.
I think it's interesting that Esco has called it safety training - what a clever 'twist'. As far as safety goes, the pressure is exactly 1.6 times that of R22. R22 is also unsafe if you do it wrong, as is R12, etc, etc.
The fear that gripped many old timers is what kept them from embracing it in the first place.
Should you have respect for pressurized gases? Yes. Promote Fear? Kind of Borderline.
But safety is always important. I'm sure somebody will try and make a buck off training R410 any way they can. I suggest taking a good 2 to 4 hours R410A class. just make sure you know your R22 stuff terms and charging procedures before you go take the 410 class
The classes I did when with a manufacturer were free, but I squeezed in a few minutes of product sales info. :D
.....Hmmmm ...Maybe I should start an R410A Thermostat safety class ........:couchhide:
