Condensate Pan Level Sensors

Detect water buildup in HVAC condensate pans and trigger alarms or shut-offs—preventing overflow, building damage, and mold growth.

Float Switches

Accurately control fluid levels in tanks and reservoirs—automating pump systems and preventing flooding or pump burnout.

Custom HVAC Sensor Solutions

We design and build custom sensors to integrate seamlessly into your HVAC and refrigeration equipment—tailored to meet your exact technical, electrical, and installation requirements.

Why Leak and Level Monitoring Matters in HVAC-R Systems

Even small leaks or overflowing condensate pans can cause major issues in HVAC-R systems—including mold growth, ceiling damage, and operational downtime. MadisonSensor’s early-detection sensors help prevent these costly failures while supporting energy efficiency, equipment longevity, and code compliance.
