🌸🚨 SPRING WARNING: Float Switch Tripping? Don’t Ignore It — It’s a Safety Shutoff 💧🏠
If your A/C has been starting up and then shutting off, or it won’t stay running in COOL, don’t assume the system is failing. In many homes, the float switch (safety switch) is what stops the unit when it detects water buildup in the drain pan.
Spring humidity in Houston means your A/C pulls more moisture from the air, creating more condensate water. If the drain line is partially clogged (algae/sludge/dust) or the pan isn’t draining correctly, water backs up and the float switch trips to prevent an overflow — protecting your ceilings, walls, attic insulation, and flooring from 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
• You keep needing to reset the system
⚠️ Important: Never bypass the float switch. It’s there to protect your home. The right fix is to find and solve the cause (most often a drain problem) and confirm the safety switch is working properly.
🧰 What we do on a float switch / spring check:
• Inspect and clear/flush the drain line
• Check the drain pan (primary & secondary)
• Test float switch operation
• Confirm proper drainage + normal system operation
