An AC or heat pump system is only as good as its evaporator coil. The Goodman CAPTA evaporator coils are designed with this simple thought in mind for its longevity, accessibility, and value as their other heating and cooling equipment. The advanced design and all-aluminum constriction of this coil improves its durability and heat transfer efficiency. The CAPTA series are cased A-Coils for use in Upflow/Downflow applications. These units include an internal TXV (thermostatic expansion valve), which is perfect for high-performance systems. Goodman pressure tests each coil twice prior to it leaving the factory. Whether you are replacing an old failing coil or installing a new system, you can choose Goodman's CAPTA units with confidence.
Features
All-Aluminum Coil: Goodman's evaporator coils maximize surface area and optimize heat transfer for efficient comfort by using a reliable all-aluminum design complete with sine fins and grooved tubes.
Internal Thermostatic Expansion Valve: Goodman's CAPTA units have a factory-installed internal thermostatic expansion valve, which streamlines installation and maintains ideal refrigerant flow for your system.
Cabinet Durability: Providing superior longevity and efficiency, CAPTA units have a galvanized, embossed, and insulated cabinet that protects the coil and prevents air leakage.
Condensate Management: Keeping your system sage and operational, the CAPTA units feature a foil-faced insulation to inhibit the formation of condensate and a rust-resistant, DecaBDE-free thermoplastic drain pan secondary drain connections. The drain pan is UV-resistant.
R32 Compatibility: Complies with Clean Air Act New Refrigerant Requirements.
Perfect Match for R‑32 Split Systems The Goodman CAPTA3626B3 3 Ton Evaporator Coil is engineered for R‑32 refrigerant, ensuring compatibility with modern HVAC condensers and heat pumps designed for lower environmental impact.
Precise Factory‑Installed TXV for Efficiency With a factory‑installed thermostatic expansion valve (TXV), this coil enables accurate refrigerant metering, improving overall system efficiency, reducing superheat swings, and enhancing humidity control compared with fixed‑orifice coils.
All‑Aluminum Coil Enhances Heat Transfer & Durability The all‑aluminum tube and fin design boosts heat exchange while resisting corrosion, supporting reliable long‑term performance and lower maintenance needs.
Flexible Upflow/Downflow Installation Designed for upflow and downflow configurations, this coil fits a wide range of residential HVAC layouts — including attics, basements, and closets — with a 17.5″ cabinet width that matches common furnace sizes.
Advanced Condensate Management & Insulation Foil‑faced insulation and rust‑resistant thermoplastic drain pans with secondary connections help reduce moisture issues and improve indoor comfort by minimizing condensation and corrosion risks.
Installer‑Friendly Access & Service Features like a single front access panel and standardized copper suction stub make charging and diagnostics easier for HVAC professionals, reducing service time.

Maintenance Tips
Replace Air Filters Every 1–3 Months – Clean filters maintain proper airflow across the all‑aluminum coil, preventing reduced efficiency and coil icing.
Keep the Coil Clean – Dust and debris on the aluminum fins reduce heat transfer; schedule annual professional coil cleaning. (hvacstore.com)
Inspect Condensate Drain & Pan – Ensure the rust‑resistant drain pan and lines remain clear to prevent water leaks and microbial growth.
Check TXV Performance – The factory-installed thermostatic expansion valve regulates refrigerant flow; periodic inspections ensure proper superheat and cooling efficiency.
Maintain Proper Airflow – Keep supply and return vents unobstructed for optimal upflow or downflow operation.
Inspect Cabinet & Insulation – The insulated galvanized cabinet reduces condensation; check annually for moisture or damage.
Schedule Annual HVAC Service – Professional maintenance helps detect refrigerant issues, clean internal components, and maintain peak system performance.
