Welcome to the Cool Zone™


When it comes to choosing an air conditioning system for your bus fleet, quality, reliability and performance are critical. Bergstrom’s new Cool Zone™ school bus air conditioning system is a solution you can count on.

Bergstrom began producing heaters for Carpenter & Thomas school buses in 1952 and has grown into the largest supplier of school bus heaters in the U.S. Bergstrom has taken this industry expertise and engineered an OEM-quality air conditioning system for the school bus market that will keep students comfortable and happy.

The system consists of front and rear bulkhead units, a midship unit with two three-fan condensers and two compressors. The result? Cool Zone™ is so effective that it cools the bus down five minutes faster than what’s required by Florida specs.*
