🌸🚨 SPRING WARNING: Float Switch Tripping? Don’t Ignore It — It’s a Safety Shutoff 💧🏠
If your A/C has been turning on and then shutting off, won’t stay running in COOL, or you keep needing to “reset” it, your system may not be broken. Many times, the float switch (safety switch) is doing exactly what it’s designed to do: shut the unit down when it detects water buildup in the drain pan.
Why this happens in spring
In Houston, spring humidity climbs fast. Your A/C removes more moisture from the air, creating more condensate water. If the drain line starts to clog (algae/sludge/dust) or the pan isn’t draining properly, water backs up and the float switch trips to prevent overflow—helping protect your ceilings, closets, attic insulation, and floors from expensive water damage.
✅ Common signs your float switch is tripping:
• A/C turns on, then shuts off again
• Thermostat calls for cooling but the system won’t keep running
• Musty smell near the indoor unit or vents
• Water in the drain pan or around the air handler
• Repeated shutoffs during humid days
⚠️ Important: Never bypass the float switch. It’s a safety device. The right solution is to clear the drain issue and confirm the switch is operating correctly.
🧰 What we check during a spring visit:
• Drain line inspection + cleaning/flush
• Drain pan inspection (primary & secondary)
• Float switch operation test
• Confirm proper drainage + normal system operation
