Why it matters to you
In the Lowcountry, line sets often run through humid crawlspaces and along sun-baked exterior walls, where cracked or missing insulation causes sweating, lost capacity, and water damage. Salt air and UV also degrade exposed insulation and connections faster near the water.
Practical guidance
Look at the exposed line set by your outdoor unit once a season; if the insulation is cracked, missing, or dripping, ask a licensed technician to replace it. When replacing equipment, have the installer confirm whether the existing line set is the right size and condition for the new refrigerant, or whether it should be replaced.
