FAQs:

1. Can R‑410A be used in R‑22 systems?
   No—its higher pressure requirements make it incompatible.

2. Why choose R‑410A over older refrigerants?
   It improves efficiency and eliminates ozone impact.

3. Is AZ‑20 still used in new installations?
   Current regulations limit usage; many manufacturers transitioning to low‑GWP alternatives.
