No, it is not legal to purchase R410A refrigerant without a license.
R22 needs import license,R410A does not need anything special
R410A refrigerant was introduced to replace R22, as R22 is ozone-depleting and harmful to the environment. R410A is a more environmentally friendly alternative with zero ozone depletion potential.
short answer: Only people with and EPA certification may purchase R22 and/or R410A refrigerants.
Yes, R410a is an azeotropic refrigerant, meaning it is a mixture of two or more refrigerants that behaves as a single substance with a constant boiling temperature.

Converting an R22 system to use R410A refrigerant involves replacing the existing components with ones that are compatible with R410A. This typically includes the compressor, expansion valve, and possibly the condenser and evaporator coils. It is important to consult with a qualified HVAC technician to ensure the conversion is done correctly and safely.
An empty R410A refrigerant cylinder weighs approximately 33-35 pounds.
When converting from R22 to R410A refrigerant in an HVAC system, key considerations include ensuring compatibility with the system components, proper flushing of the system to remove old refrigerant and contaminants, adjusting the system's pressure and temperature settings, and following safety guidelines to prevent leaks and ensure efficient operation.
To convert an HVAC system from R22 to R410a using a conversion kit, the process typically involves recovering the existing R22 refrigerant, replacing the compressor oil with a compatible oil for R410a, installing a new filter drier, flushing the system to remove any remaining R22, and then charging the system with the new R410a refrigerant. It is important to follow manufacturer guidelines and consult with a professional HVAC technician to ensure proper conversion and system performance.

Bubbles in the sight glass of an R410a system can indicate a refrigerant charge issue, such as undercharging or a refrigerant leak. It is important to address this issue promptly to prevent damage to the system and ensure optimal performance. A qualified HVAC technician should be consulted to diagnose and resolve the problem.
