Wipe off the condensation and wrap a few winds of the sticky poly tape on the tubing where it exits the house. Then dry and wrap the service valve on the condenser end of the tubing. Squeeze it in tight around the tubing.
Slip the new foam over the tubing and on top of the cork tape. Remove the adhesive liner, align the edges and press the seam together as you go. Be careful. Once the glued ends touch, you can’t get them apart again.
Measure the length of the A/C line and cut the insulation a few inches longer. Leave the adhesive liner in place and install the insulation.
Have the necessary tools for this DIY project lined up before you start—you’ll save time and frustration.
