What is a Float Switch?

A float switch is a safety device installed in your AC condensate drain line to prevent water from overflowing into your home. It's usually a small plastic or metal device that floats on the surface of the water in the drain pan. When the water level rises too high, the float switch trips, shutting down your AC to prevent further damage.

Common Causes of Float Switch Trips

There are several reasons why a float switch might trip, including:

  • Clogged condensate drain lines: If your drain line is clogged with debris, dirt, or mold, it can cause the water to back up into the drain pan, triggering the float switch. Our AC condensate drain trap cleaning near me service can help clear out any blockages.
  • Dirty or faulty float switch: If the float switch itself is dirty or faulty, it may not function properly, causing it to trip unnecessarily. Our AC safety float switch repair service can help fix or replace the switch.
  • Improperly installed or maintained AC system: If your AC system was not installed or maintained correctly, it can lead to issues with the float switch. Our team of experts at ClearFlow HVAC Solutions Pros can help you identify and fix any problems.
