Homes with pets or allergies often need closer to every 30 days. **What is the A2L refrigerant transition?** It is the industry-wide shift away from R-410A toward A2L refrigerants such as R-32 and R-454B. It changes what refrigerant new systems use; existing R-410A systems can still be used and repaired. **Do I need to do anything to my AC before leaving for the season?** Yes. A system left off for months can develop problems that show up the moment it restarts. Schedule a check before you leave or before you return. ## Have a Question We Have Not Covered?
