How can I ensure that my refrigerant piping insulation is properly installed and maintained?

Ensure that the insulation is properly sized and fitted to the piping, and that all joints and connections are securely sealed. Regularly inspect the insulation for signs of damage, moisture intrusion, or compression. Check the insulation’s temperature rating and ensure it is suitable for the system’s operating conditions. Finally, consider using insulation with built-in vapor barriers to prevent moisture intrusion.
