Goodman CAPTA1818A3 1.5 Ton Vertical Evaporator Coil R32

Engineered for residential cooling and heat pump systems that demand more, the Goodman CAPTA1818A3 pairs all-aluminum coil construction with R-32 refrigerant compatibility. This combination delivers strong heat transfer performance while keeping your environmental footprint in check. This is a coil built for installers who value efficiency on the job and homeowners who expect reliability long after the truck leaves the driveway.

What's Inside the Box

• All-Aluminum Coil Construction – Aluminum runs cooler, resists corrosion naturally, and transfers heat effectively — making it a smart long-term choice over traditional copper-aluminum blends.
• Factory-Installed TXV – The thermal expansion valve comes pre-installed, dialing in refrigerant flow from day one and cutting down on setup time at the job site.
• Check Flowrator Included – Purpose-built for cooling and heat pump operation, ensuring proper refrigerant direction and system compatibility without additional components.
• Standard Copper Suction Tube Stub – A universal connection point that keeps installs straightforward and compatible across common system configurations.
• Single-Panel Access – One panel is all it takes to get inside for maintenance or inspection — less downtime, less hassle.
• 21" Compact Depth – Sized to fit where it needs to go, including attic installs where clearance is tight and every inch matters.
• Foil-Faced Insulation – Reduces cabinet condensation and keeps thermal energy where it belongs, improving overall system efficiency.
• Galvanized Leather Grain-Embossed Cabinet – Rust-resistant and built to handle the physical wear that comes with real installations in real environments.

Drain Pan — The Details That Matter

The CAPTA1818A3 doesn't cut corners on drainage. The thermoplastic drain pan is corrosion-resistant, UV-stable, and completely DecaBDE-free — meaning no harmful flame retardants in the material. A low water-retention design moves condensate out quickly, and secondary drain connections offer extra protection against overflow. Drain pan rails let you remove and reposition the pan without disturbing the structure of the unit.
