Our long lasting, residential systems create the best air possible for your home. Whether you need a new air conditioner, heat pump or furnace, a Trane system can help you take control of your home's indoor temperature.


An air handling unit circulates both cool and warm air evenly in your home. The efficient variable speed motors deliver steady temperatures and control indoor humidity levels to keep you comfortable during every season.

Built to Withstand any Environment

The all-aluminum coil in our air handlers is more reliable than conventional copper coils. What does this mean for you? Our air handlers have a longer system life and less chance of refrigerant leaking into the atmosphere. All Trane electrical components are extensively tested and required to preform at reliability levels far exceeding standard longevity levels. Plus, the modular design enhances flexibility, allowing installation in tight spaces - without the need for expensive remodeling to your home.

Hyperion™ Series

The extraordinary Trane Hyperion™ air handler represents a substantial advance in air handling technology. Using 14 industry-exclusive patents, the Hyperion offers significant advantages over other air handlers, advantages like refrigerator-styled insulation made without exposed fibrous material, which virtually eliminates sweating and condensation as well as helping create a safer environment for your home.
