    FAQ

    1
    What does this HVAC condensate float switch do and when will it activate?
    The float switch monitors the condensate drain pan or drain line and automatically interrupts the cooling system or condensate pump when water rises to a critical level. It prevents overflow and water damage during heavy condensate production—common in hot, humid climates like Florida—by shutting the system off until the drain issue is resolved.
    2
    Where should I install the float switch and how is it mounted?
    Install it in the primary drain pan or inline on the condensate drain (using the supplied clamp/bracket or a saddle fitting) at the point where rising water would back up. Position it so the float can move freely and wire it per the product instructions—typically in series with the condensate pump or the air handler/compressor control circuit. If you’re unsure about wiring or access, use a licensed HVAC pro.
    3
    Will this float switch fit my central AC or air handler?
    It’s designed to fit most central AC systems and air handlers, but you should confirm drain pan dimensions, drain line diameter, mounting method, and control-voltage compatibility for your unit. Check the product manual or specs for cable length and whether the switch contacts match your control board or pump requirements.
    4
    How do I test the float switch and what happens after it trips?
    To test, shut down power to the unit (if required), then pour water into the drain pan until the float rises and the switch trips. The system or pump should stop when triggered. Many float switches automatically reset when the water level falls, but some models require a manual reset—always consult the included instructions before testing.
    5
    How should I maintain the float switch to avoid false trips or failures?
    Inspect and clean the drain pan, drain line, and float every 3–6 months (more often in very humid conditions). Remove algae, debris, and buildup; use algaecide tabs if appropriate; verify the float moves freely and the drain line slope and trap are correct. Regular maintenance reduces nuisance shutdowns and water-damage risk.
    6
    What if the switch keeps tripping or won’t reset—what troubleshooting steps should I take?
    First check for a clogged drain line, full/failed condensate pump, or misaligned float. Verify wiring and control connections and test continuity with a multimeter if you’re comfortable doing so. If the drain is clear and wiring looks correct but the problem persists, turn the system off and contact an HVAC technician to prevent continued shutdowns or water damage.
