2012 Hot 50 Editor Picks: HVAC

Trane "EarthWise Hybrid": The company's EarthWise Hybrid all-in-one system contains the same components found in an EarthWise Hybrid Split System. However, they are all engineered to work and fit together in one attractive cabinet. www.trane.com

Uponor "Radiant Ready 30E": Radiant floor heating is a good way to address indoor air quality, as there are no ducts to collect dirt/allergens. The "more comfortable" heat, rising from the floor versus being blown around in the air, means homeowners may be able to keep the temperature lower. www.uponor-usa.com

Panasonic "WhisperGreen": This product is up to 781% more energy efficient than Energy Star standards. www2.panasonic.com
