The Trane Climatuff® compressor was the world's first successful heat pump compressor.

The Trane Climatuff® compressor is the heart of our air conditioning and heat pump systems. It is part of the outdoor unit and pumps refrigerant in order to meet the cooling requirements of the system. To this day, the Climatuff® compressor is the only one Trane uses in its residential systems. It's well known for its superior durability, its low noise levels and high efficiency.
