How do you charge 410a.
When R-410A is recovered from an appliance it: A) can be mixed with either R-32 or R-125 during recovery process, since R-410A is a mixture of those two refrigerants B) can be mixed with R-134a but not R-22 during recovery C) need not be recovered since R-410A is not one of the refrigerants covered by the clean air duct D) should be recovered ...
R-410A's Global Warming Potential (GWP) is 1,725 times that of Carbon Dioxide. This large number is why 410A is being pressured to be phased out. While R-32 is an HFC it's GWP is only 675. That is about a sixty percent decrease. It's not a perfect bullet but it would help with the battle against Global Warming.The short answer is no; you don't need to recharge your AC unit on a set schedule. In fact, most units only need to be recharged once every two to five years - and sometimes even longer than that. The main exception to this rule is if there's a leak in the system, which will cause the refrigerant level to drop over time.Mar 30, 2019 ...

Condenser subcooling is an excellent indicator of the system's refrigerant charge, but it is not the only one. The lower the refrigerant charge, the lower the subcooling. The higher the charge, the higher the subcooling. For instance, you may need 0.01 lb of refrigerant per additional ft. To charge refrigerant into the mini split, partially open the blue valve on the manifold gauge for 1-2 seconds and shut the valve to release about 5 oz of refrigerant into the mini split at once. Do not insert too much refrigerant at once.
