Goodman 2 Ton R32 Vertical Evaporator Coil - CAPFA1818A3

Goodman CAPFA1818A3 1.5 Ton R32 A-Coil Evaporator Coil

Don't let the compact size fool you — the Goodman CAPFA1818A3 is a versatile, efficiency-focused evaporator coil that adapts to how you need it installed and what system you're pairing it with. Whether you're running an AC-only setup or a heat pump, and whether your application calls for upflow or downflow orientation, this coil is built to fit the job without compromise.

One thing worth noting upfront: this coil is intentionally rated at 1.5 tons, which may exceed the tonnage of its paired condenser in certain configurations. That's by design — oversizing the coil relative to the condenser helps maintain overall system efficiency and keeps energy costs in check over time.

What Makes It Work

• Upflow & Downflow Compatible – Flexible orientation support means this coil works across a wider range of system layouts without requiring additional components or modifications.
• AC & Heat Pump Ready – No need to spec a different coil depending on the condenser type. The CAPFA1818A3 handles both applications reliably.
• Check Flowrater Expansion Device – Designed to perform across varying system conditions, keeping refrigerant flow consistent whether you're in cooling or heat pump mode.
• R-32 Compliant – Meets Clean Air Act requirements for new refrigerant standards, making this coil a forward-compatible choice for modern installs.
• Low Air Leakage Design – Foil-faced insulation minimizes air loss within the cabinet, pushing more conditioned air into your ductwork where it actually counts — improving comfort and reducing unnecessary run time.
• Split-Seam Front Access – When maintenance is needed, a split-seam casing on the front of the unit makes internal access quick and clean without major disassembly.

Built to Last

The cabinet is constructed from galvanized steel with a leather-grain embossed finish — sturdy enough to handle real-world installation conditions while resisting corrosion over time. The rust-resistant thermoplastic drain pan features a low water-retention design that outperforms older models, reducing standing condensate and the problems that come with it.

Quick Specs

Warranty

The CAPFA1818A3 is backed by Goodman's 10-year parts warranty, provided the unit is installed in accordance with local and state codes, paired with a compatible condenser, and registered online through Goodman's manufacturer portal.

Please Note: This coil requires a separate furnace or air handler blower and condenser to operate — all sold separately. It is not compatible as a replacement for single-piece air handler coils.

The Bottom Line

The CAPFA1818A3 hits the mark for installers and homeowners who need a dependable, versatile coil that works across multiple system types and orientations without a premium price tag. Efficient airflow, durable construction, and a solid warranty make it a practical choice for residential HVAC upgrades and new installs alike.
