The Goodman CAPTA1818B3 is a 1.5-ton (18,000 BTU) all-aluminum cased A-coil evaporator designed for modern R-32 (A2L) split-system air conditioners and heat pumps. It features a factory-installed thermal expansion valve (TXV), AlumaFin7 coil technology, and a compact 17.5-inch cabinet optimized for residential installations.
Dimensions
- Cabinet: 17.5″ W × 21″ D × 18″ H
- Plenum opening width: Approximately 16.5″
- Weight: ~35 lbs (shipping weight typically 35–40 lbs)
- Line connections: 3/8″ liquid / 3/4″ suction (sweat/copper stubs)
- Drain connections: 3/4″ FPT primary and secondary
The 21″ depth improves attic access compared with deeper traditional coils.
Key Features
- All-aluminum AlumaFin7 evaporator coil (aluminum tubing, fins, and end plates) for excellent heat transfer and corrosion resistance
- Factory-installed TXV sized for both cooling and heat-pump applications
- Optimized refrigerant circuits and manifolds specifically for R-32
- Integrated R-32 leak-detection sensor designed for the life of the coil
- Single front access panel for easier service
- Foil-faced insulation to reduce cabinet condensation
- Galvanized leather-grain embossed painted cabinet (nickel gray finish)
- DecaBDE-free, UV-resistant, rust-resistant thermoplastic drain pan with low water-retention design and secondary drain connections
- Drain pan rails that allow coil repositioning without compromising structural integrity
- Standardized copper suction tube stub length
- AHRI certified and ETL listed
Benefits
- Supports the industry transition to lower-GWP R-32 refrigerant (compliant with AIM Act requirements for A2L systems)
- Improved efficiency and precise refrigerant metering via the factory TXV
- Superior corrosion resistance and longer service life versus traditional copper-tube coils
- Easier installation in tight attic or closet spaces thanks to the shallow 21″ depth and accessible front panel
- Reduced condensation and better moisture management for cleaner operation
- Reliable performance when matched with compatible Goodman/Amana R-32 outdoor units
- 10-year limited parts warranty (with online registration)
