🌸💧 Why You Should Check Your Float Switch (Before Your A/C Shuts Off!) 💧🌸

Your float switch (safety switch) is a small part with a big job: it helps prevent water damage by turning your A/C off when it detects a problem with drainage. In spring and summer—when humidity is high—this is one of the most common causes of “random shutdowns.”

Here are the main reasons you should have your float switch checked:

✅ 1) Prevent Water Damage
When the drain line clogs, water backs up into the drain pan. The float switch trips to stop the system before it overflows into ceilings, closets, attic insulation, or floors.
✅ 2) Avoid Unexpected A/C Shutdowns
If the float switch is dirty, stuck, failing, or tripping due to drainage issues, your A/C may stop running suddenly—often on the hottest day.
✅ 3) Catch Drain Problems Early
A tripping float switch usually means:
Clogged drain line
Drain pan holding water
Improper drain slope or blockage
Algae/sludge buildup
Fixing this early is usually fast and inexpensive compared to repairing water damage.
✅ 4) Reduce Mold & Musty Odors
Standing water can lead to musty smells, mold growth near the air handler, and poor indoor air quality. Checking the float switch and drain system helps keep the area clean and dry.
✅ 5) Protect Your HVAC System
If the system is repeatedly shutting off and on, it can put stress on components and leave your home uncomfortable. A proper check helps your system run steady and efficient.
✅ 6) Safety & Peace of Mind
Some systems have multiple safety switches (primary/secondary pan, wet switch, etc.). Testing them ensures your home is protected—especially if your unit is in the attic or a closet.
