AC Drain Pan: Must-Have Accompaniment for Your AC Unit

Airtight homes can be energy-efficient, but they require special care to avoid issues like inadequate air quality and humidity buildup. One such issue is water accumulation, which can lead to damage if not addressed properly. This is where a humble yet crucial component of your HVAC system comes into play: the drain pan for your AC unit.

The Importance of a Drain Pan in Your AC Unit

The primary function of a drain pan in an AC unit is to collect condensed water from the indoor coil. This is a natural process where the cold evaporator coil causes warm, humid air to condense, releasing water.

The drain pan ensures that this water doesn't leak onto the floor or walls, preventing potential damage to your home and promoting air quality by preventing mold growth.

Drain pans come in various types, with the most common being the primary and secondary drain pans.

Primary Drain Pans: Used to collect condensation directly from the coil. They often have a hole in the center to facilitate drainage.
Secondary Drain Pans: Designed to catch water from the primary pan and direct it towards the main drain line. They serve as a backup to prevent overflows.
