FAQ

AC Drain Line Clogged Questions

Can I clear my own AC drain line?

NILOV does not recommend attempting to blow out, snake, or pour chemicals into the line yourself. Clearing it correctly usually requires the right tool and knowing exactly where the line runs.

Why do drain lines clog so often in South Louisiana?

Our humidity means the AC pulls a lot of moisture out of the air, which creates ideal conditions for algae and sludge to build up inside the drain line over time.

What happens if I ignore a clogged drain line?

Water can back up and overflow near the indoor unit, leading to flooring damage, ceiling damage, or mold growth. It is worth addressing quickly.
