'Building Products' magazine selected Trane and Mitsubishi as 2009 Green Product Award winners! Here is what the article from 'Building Products' had to say about these award winners:

Trane - XL 20i 

The XL 20i air conditioner/heat pump boasts 20-SEER efficiency and includes ComfortLink II with Charge Assist. Plug-and-play ComfortLink II requires just two wires for installation and provides a digital interface for precise setup; ComfortLink II-enabled indoor and outdoor units communicate for automatic and proper charging, configuration, and calibration. The Energy Star-qualified unit includes R410A refrigerant; dual compressors for two-stage heating and cooling; and an all-aluminum Spine Fin coil with low air resistance, greater heat exchanging capabilities, and more corrosion and leak resistance, the maker says. "The ease of installation and service, along with the added efficiencies make this a very attractive option for AC," one judge commented.

Mr. Slim M-Series heat pump systems qualify for an Energy Star Tier 2 rating, measuring in at 22 or 25 SEER, up to 75 percent better than the industry standard of 13 SEER, the maker says. Even at 17 degrees F, the MSZ-FD models produce up to 13,600 BTU/h of heat, says the company. No ductwork is required at installation, and the product includes zone control to cool and heat only desired spaces. "It is significant to have an electric source heat pump operating at this level of efficiency," one judge remarked. "They have created a quality product with simple measures for application."
