The Goodman CAPTA4230D3 is a high-efficiency, all-aluminum cased A-coil evaporator designed for residential split-system air conditioning and heat pump applications. Optimized exclusively for R-32 refrigerant, this 3.5-ton (42,000 BTU) coil delivers reliable cooling performance for homes roughly 1,700–2,100 sq ft (depending on climate, insulation, and load calculations). It features a factory-installed thermostatic expansion valve (TXV) for precise refrigerant metering and is built for flexible upflow or downflow installation.
Dimensions
- Width: 24.5 inches
- Height: 30 inches
- Depth: 21 inches
- Approximate weight: 70 lbs
These dimensions fit standard 24.5-inch cabinet openings common in many residential installations.
Key Features
- All-aluminum construction (tubing, fins, and end plates) for excellent heat transfer and corrosion resistance
- Factory-installed internal TXV for accurate refrigerant control and improved system efficiency
- Cased design with painted cabinet for durability and a clean appearance
- Rust-resistant, high-temperature thermoplastic drain pan with low water-retention design and secondary drain connections
- Multi-position capability: upflow or downflow
- Compatible with both cooling-only and heat pump systems
- Designed for R-32 refrigerant only (A2L compliant, lower global warming potential than older refrigerants)
Benefits
- Enhanced efficiency and performance when paired with matching R-32 outdoor units
- Longer coil life thanks to all-aluminum construction that resists formicary corrosion better than traditional copper-aluminum coils
- Easier, more flexible installation with dual-orientation capability and factory TXV (reduces field labor)
- Better moisture management and reduced risk of water damage from the advanced drain pan design
- Environmentally friendlier R-32 refrigerant supports compliance with current regulations (including AIM Act transitions)
- Reliable cooling for medium-to-large homes with consistent temperature control
Specifications
- Capacity: 3.5 tons / 42,000 BTU
- Refrigerant: R-32 only
- Coil Type: Cased A-coil (vertical)
- Airflow Direction: Upflow / Downflow
- Liquid Line Connection: 3/8 inch
- Suction Line Connection: 7/8 inch
- Material: All-aluminum
- Expansion Device: Internal TXV
- Approximate Airflow: Around 1,900 CFM (system-dependent)
- Warranty: Typically 10-year limited parts warranty when registered (confirm current terms with manufacturer/distributor)
Compatibility
The CAPTA4230D3 is designed for use exclusively with R-32 refrigerant systems. It pairs with AHRI-matched Goodman (and some Amana/Daikin) R-32 outdoor condensers or heat pumps in the appropriate tonnage range. It is not compatible with R-410A or other refrigerants. Always verify AHRI matchups for the specific outdoor unit to ensure proper performance, efficiency ratings, and warranty coverage. Suitable for new installations or replacements in existing upflow/downflow air handlers or furnaces with matching cabinet width.
This Goodman coil is a solid choice for contractors and homeowners upgrading to or installing modern R-32 split systems who need a durable, efficient, and installation-friendly indoor coil. Always consult local codes, a licensed HVAC professional, and current manufacturer literature for exact matching, installation, and warranty details.
Key features
- 3.5-Ton Cased Evaporator Coil — upflow or downflow configuration
- Built for R-32 — matched to Goodman R-32 ACs and heat pumps
- Factory-Installed TXV — precise refrigerant metering
- All-Aluminum Construction — resists corrosion for long service life
