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.
