1. Can 404A replace R‑22 systems?
   Not directly—R‑22 systems are not designed for its low-temperature operating profile.

2. Is R‑404A environmentally safe?
   It has zero ODP but very high GWP; new regulations may restrict usage in the future.

3. What maintenance is required with 404A?
   Frequent leak detection, recovery, and recycling are essential due to high GWP impact.
