1.5 Ton

These variable-speed electric air handlers are purpose-built for reliable cooling and optional electric heat in small zones or apartments. Designed to pair with R-410A outdoor condensers, they deliver smooth airflow, quieter operation, and better humidity control. Most models in this category feature a 17.5" cabinet width and multi-position flexibility for closets, attics, or basements.

Whether you’re a homeowner upgrading an older indoor unit, a DIY-capable buyer sourcing equipment, or a contractor managing multi-family and light commercial properties, these components simplify changeouts and new installs. Use them to replace a tired air handler, match with a new condenser for cool-only operation, or add electric heat strips for backup heat without gas.

Key specs include approximately 18,000 BTU (1.5 ton) capacity, R-410A refrigerant compatibility, and variable-speed ECM blowers for balanced comfort. Many models are rated to serve 1.5-2 ton matches when properly paired. SEER2 performance is determined by the matched outdoor unit and coil configuration. Multi-position installation (upflow, downflow, horizontal) and the compact 17.5" cabinet help meet tight-clearance jobs while keeping service access manageable.

Frequently Asked Questions

  • What outdoor condensers are compatible with a 1.5-ton Goodman variable-speed air handler using R-410A?

    Use a properly matched R-410A condenser rated 1.5 tons (or approved 1.5-2 ton match). Verify AHRI matches and manufacturer guidelines for best SEER2 performance.

  • Is a 1.5-ton multi-position air handler suitable for closet or attic installation with a 17.5-inch cabinet width?

    Yes. The 17.5" cabinet is designed for tight spaces. Confirm clearances, condensate drainage, service access, and duct connections per the install manual.

  • Does this electric furnace/air handler support cool-only operation with electric heat strips?

    Yes. It operates cool-only and accepts optional electric heat kits. Choose the correct kW heat strip and circuits as required by the model.

  • What size space is typically served by a 1.5-ton air handler and when would moving to 2 tons be appropriate?

    About 600-900 sq ft in average conditions. Move to 2 tons when load calculations indicate higher demand. A Manual J is the best guide.

  • Are any additional accessories or thermostats required for variable-speed operation?

    Most units work with standard 24V thermostats. Advanced dehumidification and comfort features may require compatible thermostat options and setup.

  • What are the electrical and breaker requirements for installing this air handler?

    Follow the nameplate MCA/MOP. Heat strip kits change amp draw and may need separate circuits. A licensed electrician should size wiring and breakers.

  • Can this unit be installed in upflow, downflow, or horizontal configurations?

    Yes. It’s multi-position. Use approved orientation, drain configurations, and accessory kits (like secondary pans) per the installation manual.

  • Is professional installation required to maintain warranty coverage on Goodman air handlers?

    Yes. Manufacturer warranties require installation by a licensed HVAC professional and adherence to all codes and instructions.

  • Is this air handler compatible only with R-410A refrigerant?

    Yes. These models are for R-410A systems. They are not for R-22. For other refrigerants, use equipment specifically listed by the manufacturer.

  • What airflow (CFM) should I expect from a 1.5-ton variable-speed air handler?

    Plan for roughly 350-450 CFM per ton, about 525-675 CFM for 1.5 tons. Actual CFM depends on setup, static pressure, and comfort targets.
