Variable Speed

Variable-speed air handlers deliver precise airflow control for smoother temperatures, lower noise, and better humidity management. Match with a heat pump or AC condenser to build a high-performance system that helps meet modern efficiency standards, including SEER2, when paired with a compatible outdoor unit. With multi-position flexibility (upflow, downflow, horizontal) and optional electric heat kits, these units adapt to homes, rentals, and light commercial spaces. Typical pricing ranges from $1060 to $2510.

Choose capacities from 1.5 to 5 tons to suit your load and ductwork. Models are available for R-410A and select R32 applications-pairing the correct refrigerant-ready coil and metering device ensures optimal performance. Staging is variable for smooth ramp-up and continuous comfort. Cabinet widths include 17.5", 19.5", 21", and 24.5" to align with common plenums, and multi-position cabinets simplify replacements in tight mechanical rooms. Add an electric heat kit to create heat-on-demand (cool-only with electric heat or use as an electric furnace alternative).

Ideal for homeowners, DIY-capable buyers (purchase), licensed contractors (install), property managers, and light commercial users seeking reduced noise and better airflow control. Shop by subcategory to zero in on the right size: 1.5 Ton, 2 Ton, 2.5 Ton, 3 Ton, 3.5 Ton, 4 Ton, and 5 Ton. Professional installation is required to handle refrigerant, electrical, and code compliance.

Frequently Asked Questions

  • What tonnage variable-speed air handler should I choose for my system?

    Match tonnage to your outdoor unit and load calculation. Common sizes range from 1.5 to 5 tons; use Manual J/duct sizing or your contractor’s recommendation.

  • Are these air handlers compatible with R-32 and R-410A outdoor units?

    Yes, select models are rated for R-410A or R32. Always pair with a coil and metering device specified for the same refrigerant and capacity.

  • Can I add electric heat to a variable-speed air handler, and what sizes are available?

    Most models accept field-installed heat kits, typically 5-20 kW depending on cabinet size and breaker limits. Check the unit’s approved kit list.

  • What cabinet width options are available and will they fit my existing ductwork?

    Widths include 17.5", 19.5", 21", and 24.5". Measure your plenum and return to choose the closest match or plan simple transition pieces.

  • Is professional installation required for variable-speed air handlers?

    Yes. A licensed HVAC pro is required for refrigerant handling, wiring, breaker sizing, airflow setup, and code-compliant startup.

  • How does a variable-speed air handler improve comfort and noise levels?

    The ECM blower ramps gradually and adjusts CFM, reducing temperature swings, improving humidity control, and lowering operating sound.

  • Are these units suitable for multi-position (upflow/downflow/horizontal) installations?

    Yes. Most models are multi-position for flexible placement during replacements or new installs.

  • Can these variable-speed air handlers be used in light commercial applications?

    Yes, many 3-5 ton models serve small offices and retail spaces when properly sized and installed.

  • Do I need a special thermostat for variable-speed operation?

    Most units work with standard 24V thermostats; a multi-stage or humidity-capable thermostat can enhance control where supported.

  • How does SEER2 relate to the air handler?

    SEER2 is a system rating. The air handler’s variable-speed blower helps the matched system achieve its listed SEER2 when paired correctly.
