A condensate drain removes the water created when an HVAC system cools and dehumidifies air. Moisture collects in a drain pan and flows through a pipe or hose to a safe drain point, preventing water damage, mold growth, and system issues.

Condensate drains protect equipment and prevent water damage.
On hot, humid days, the condensate drain carries away the moisture pulled from indoor air, keeping the system and home dry.
Flush the drain line periodically with a vinegar solution to reduce clogs and microbial growth.

Modern high‑efficiency HVAC systems often produce more condensate, making drain care even more important.
How do I know if my condensate drain is clogged?
Signs include water near the unit, musty odors, or higher indoor humidity during cooling.
Is cleaning the drain line DIY‑friendly?
Basic flushing can be DIY, but persistent clogs or leaks should be handled by a technician.
Do furnaces have condensate drains too?
High‑efficiency furnaces do. They create condensate that must be drained safely.
