An AC stoppage occurs when your air conditioning system’s condensate drain line becomes clogged, preventing the excess moisture from draining properly. This clog, often caused by algae or mold growth, can cause the air conditioning unit to turn off to avoid overflow. If left untreated, AC stoppages can lead to decreased efficiency, mold growth, and even water damage to your home.
In this article, we’ll explore why these stoppages happen, how algae and mold can be harmful and provide simple DIY solutions. For more complex issues or professional help, homeowners can rely on a trusted plumber in Cypress TX .
Why Do AC Stoppages Occur?
When the growth becomes severe, it can lead to clogs that block water flow, causing AC stoppages. For persistent issues or professional maintenance, homeowners can rely on a trusted plumber in Cypress to inspect and restore proper AC function.
Not only do these clogs impede the AC’s functionality, but they can also damage the unit and lead to costly repairs. When algae in the AC drain line and mold in the system multiply, they can:
-
Reduce AC Efficiency: Blocked tubes mean excess water accumulation in the drain pan, causing the AC to turn off to prevent overflow. This reduces cooling efficiency, leaving your home uncomfortable during Cypress’ hot summers.
-
Cause Foul Odors: Algae and mold buildup lead to stagnant water, which can cause bacteria growth and unpleasant odors circulating through your home.
-
Compromise Indoor Air Quality: Mold in the AC drain line is a health risk, potentially triggering allergies or respiratory problems, especially in sensitive individuals.
-
Lead to Water Damage: Overflowing water from a clogged drain pan can damage your home’s walls, ceilings, and floors, leading to expensive repairs.

The Problem with Algae and Mold Growth in AC Drain Lines

Flush the Tube: Use a mixture of equal parts white vinegar and water or a mild bleach solution to flush out the algae and mold. Let the solution sit for several minutes before rinsing the tube with clean water to clear any remaining debris.

Reattach the Tube: Once clean, securely reconnect the tube to the drain pan and outdoor unit.

Regular Maintenance: Clean the AC drain tube once or twice a year, especially before summer, to avoid clogs and keep your system running smoothly.
