The Goodman CHPTA3630B3 is a 3-ton cased horizontal evaporator coil built by Goodman (Daikin Comfort Technologies) for split-system air conditioners and heat pumps running on R-32 refrigerant. It pairs with a compatible Goodman furnace or air handler and outdoor condensing unit to complete a cooling or heat pump system.
Dimensions
- Cabinet: 30″ W x 21″ D x 17-1/2″ H
- Gross weight: approximately 66 lbs
- Cabinet width class: 17-1/2″ (fits matching furnace/air handler cabinets of the same width)
Key Features
- All-aluminum coil construction (tubing, fins, and end plates) for corrosion resistance and efficient heat transfer
- Factory-installed thermal expansion valve (TXV) for precise refrigerant metering in both cooling and heat pump operation
- Optimized circuitry and manifolds engineered specifically for R-32 refrigerant, including an R-32 sensor rated for the coil’s lifespan
- 21″ cabinet depth designed for tight attic or crawl space installs
- Single front access panel with split-seam design for simplified maintenance
- Foil-faced internal insulation to reduce cabinet sweating/condensation
- Rust-resistant, DecaBDE-free thermoplastic drain pan with low water retention and secondary drain connection
- Galvanized, leather grain-embossed, nickel-gray painted cabinet finish
- Standardized copper suction tube stub length for easier line set connection
Benefits
- Lower installation cost/time — factory TXV means one less field-installed component
- Better indoor comfort — precise refrigerant control improves temperature consistency
- Longer service life — all-aluminum construction resists corrosion better than copper/aluminum hybrids
- Attic/crawlspace friendly — compact 21″ depth eases tight-space installs
- Environmentally lower impact — R-32 refrigerant has zero ozone depletion potential (ODP)
- Peace of mind — AHRI certified and ETL listed, backed by a 10-year limited parts warranty (with online registration)

Compatibility
- Designed for horizontal installations only (attic, crawl space, or other horizontal ductwork orientations)
- Must be paired with a furnace or air handler blower and a separately sold outdoor condenser — not a standalone unit and not a replacement coil for single-piece air handlers
- Best matched with R-32 outdoor condensers (e.g., Goodman/Daikin GLXS4BA3010, GLZS4BA3010 series) — pairing with R-410A condensers voids AHRI certification
- Cabinet width must match the connecting furnace/air handler (this model uses the 17-1/2″ wide cabinet family — also available in 14″ and 21″ widths for other cabinet sizes)
- Suitable for homes in roughly the 1,000–1,800 sq ft range depending on the matched outdoor unit
- Always confirm the specific AHRI-matched system combination to preserve SEER2 ratings and warranty validity
Key features
- 3-Ton Cased Evaporator Coil — horizontal 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
