Broad Group produces clean air-conditioning systems and other sustainability-oriented products to enhance building efficiency. The company uses a patented, non-electric air chiller in its air conditioning design. Instead of using Freon (the traditionally used chiller), the system taps into natural gas to produce a solution that ultimately cools the air.

Quilt produces ductless, dual-zone home heat pumps controlled by artificial intelligence. Quilt's indoor and outdoor units, Dial and mobile app work together to create intelligent home climate control solution. To compete with established players in the heat pump market, the company has focused on software and design. One example is the over-the-air update it has implemented for existing heat pumps - the new firmware improved unit performance by over 20%. Ductless systems ensure a consistent temperature in every room. Quilt is even more efficient thanks to the Auto-Away feature, which uses smart sensors to save energy when rooms are unoccupied. Installation is simple and quick, like other ductless systems and most modern systems are currently in production. The company is building a network of certified installation partners.
