Sendal was created to solve a growing problem in homes: indoor air systems are more complex than ever, yet they are still controlled using fixed assumptions and disconnected devices. Ventilation, heating, air conditioning, dehumidification, and IAQ products often operate independently—leading to comfort issues, moisture problems, and unhealthy indoor environments, even in code-compliant homes. Sendal Breathe changes that.

Sendal is an intelligent home control software platform that actively manages how a home breathes, feels, and protects itself. Rather than relying on timers, occupancy guesses, or standalone products, Sendal continuously evaluates real-time conditions—temperature, humidity, air quality, and outdoor factors—and autonomously coordinates connected systems to deliver measurable performance.

Built specifically for HVAC contractors, Sendal works with the equipment, brands, sensors, and IAQ products they already install. There is no brand lock-in and no requirement to replace existing systems. Sendal acts as the intelligence layer above the hardware, improving system behavior, reducing callbacks, and enabling contractors to deliver higher-value IAQ solutions. Sendal is purpose-built for real homes and real climates, especially moisture-critical and high-humidity environments where ventilation alone can create problems. By focusing on performance instead of fixed prescribed compliance, Sendal helps contractors move beyond minimum code requirements and offer healthier, more comfortable homes backed by data. At its core, Sendal is about performance: better air, better comfort, and better protection for the home and occupants—automatically.
