Variable-Speed Air Handlers - Three-Stage Constant CFM

Premium air handlers for advanced efficiency and control.

Our variable-speed air handlers operate at the lowest possible power output in order to save energy. As a result of their variable speed blower, they are quieter, more efficient, and offer enhanced moisture management. These units represent Durastar’s Advanced Series and can be paired with our three-stage outdoor units for a highly efficient combination – Core Series air handlers are also available. Tested in extreme conditions and built to last using premium materials, you can depend on Durastar’s variable-speed air handlers for year-round comfort. All of our three-stage constant CFM models are adaptable for upflow, downflow, horizontal-left, and horizontal-right applications and are designed to be easily serviced. Call your contractor today to discuss which air handler is best suited for your home.

Frequently Asked questions

Is an air handler or furnace better?

Both Durastar’s furnaces and air handlers offer dependable options for distributing even airflow throughout your home. When selecting between the two, consider your location and climate. For areas with long warm seasons, an air handler will likely be more energy-efficient, however, we recommend discussing your options with a licensed contractor to ensure the best combinations of HVAC products for your home.

What does variable speed mean?

Variable speed air handlers operate at the lowest possible speed to achieve your desired indoor temperature. This results in increased energy efficiency. Variable speed units are also quieter than standard units.

Is a two-stage air handler more efficient than a single-stage air handler?

Yes, when paired with a two-stage outdoor unit, both units will operate on low capacity during milder days, requiring less energy; and switch to full capacity and power when needed.
