Aware helps contractors protect the home between service visits.

Aware monitors for early warning signs of problems such as water leaks, mold risk, freezing conditions, power loss, and HVAC system issues. It helps contractors know sooner, respond faster, and create more proactive service opportunities.

Balance helps contractors solve comfort issues caused by humidity.

Balance addresses comfort complaints tied to latent humidity load, especially in homes with high-performance HVAC systems or added ventilation. It helps contractors identify and manage humidity-related comfort problems more effectively.

Breathe identifies where IAQ problems are happening in the home and helps manage the right solution in the right area—humidity control, filtration, ventilation, and pollutant source awareness.

What contractors are saying

Built for home service professionals and proven across every U.S. climate zone, Sendal manages real-world home conditions - not just theoretical design-day assumptions.
