InstallationQuestion 30 of 110
Refrigerant suction lines on a split system are typically insulated for what reason?
a.To add structural support
b.To prevent refrigerant leaks
c.To reduce heat gain and prevent condensation on the cold line
d.To increase line pressure
Explanation
The suction line carries cold, low-pressure vapor, so it is insulated to limit heat gain that would reduce efficiency and to prevent surface condensation that drips and causes damage. The insulation should be continuous and properly sized. The liquid line is usually left uninsulated unless exposed to extreme heat.
