4 - 5 Ton Goodman R32 Horizontal Slab Coil, CSCT6012L3
The Goodman CSCT6012L3 is the top-capacity model in the CSCT series, a 4 to 5 ton cased horizontal slab coil designed for large homes running R-32 split systems on a horizontal furnace. Goodman rates it for up to 2,146 SCFM, and it packs a factory TXV, all-aluminum coil, and an R-32 leak detection sensor into a 39½" L-size cabinet. It is a strong match for high-capacity air conditioner, gas furnace, and cased coil systems where airflow and drainage need to keep up with heavy cooling loads.
Is a 4 - 5 Ton Horizontal Slab Coil the Right Size?
The CSCT6012L3 handles nominal loads of 4–5 tons, about 48,000–60,000 BTU/h, which typically means larger homes, open floor plans, or houses in hot climates with significant solar gain. At this capacity, duct sizing becomes critical. Undersized supply and return ductwork can keep the system from moving the air a 4 or 5 ton coil needs.
Goodman's airflow table for this coil runs from 800 SCFM up to a maximum of 2,146 SCFM, so verify your furnace blower can reach your outdoor unit's required airflow at your system's static pressure. Return air sizing, filter restriction, and supply register count all deserve a close look on a 5 ton install.
Ideal for: Large single-family homes, high-load living spaces, and horizontal furnace systems pairing with a 4 or 5 ton R-32 outdoor unit.
Need less capacity? Step down to the 2.5 - 3 Ton Goodman R32 Horizontal Slab Coil, CSCT3612L3, which shares this coil's 39½" cabinet footprint for 2½ to 3 ton systems.
Recommended tonnage applications are general guidelines only. Actual system requirements depend on a proper load calculation, duct design, blower airflow, and the approved outdoor unit match. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Is the CSCT6012L3 the largest coil in the Goodman CSCT line?
Yes. At a nominal 4–5 tons, the CSCT6012L3 is the highest-capacity model among the four CSCT horizontal slab coils.
What is the maximum airflow for the CSCT6012L3?
Goodman's airflow data lists a maximum of 2,146 SCFM for the CSCT6012L3, with pressure-drop data starting at 800 SCFM.
Why choose the CSCT6012L3 over the CSCT3612L3 if they share the same cabinet?
Although both use the 39½" cabinet and 30" x 21" plenum opening, the CSCT6012L3 is rated for 4–5 tons versus 2½–3 tons, and it carries a higher ship weight (58 vs. 53 lbs). Choose it when your load calculation calls for 4 or 5 tons.
Does the CSCT6012L3 need an AHRI-matched outdoor unit?
Yes. Goodman requires the complete indoor and outdoor combination to be manufacturer approved and AHRI listed. Browse outdoor condensers and confirm your match before purchasing.
What if my furnace is not an Amana, Goodman, or Daikin model?
Goodman instructs installers to check the furnace manufacturer's instructions for a mitigation mode. If it can be disabled or isn't present, the R-32 sensor is wired through the Non-A2L Furnace Integration Kit. If mitigation mode is present but can't be disabled, the furnace must be replaced.
Can the CSCT6012L3 be installed outdoors?
No. Goodman states none of the components in this product line are designed or approved for outdoor use. Install it indoors in an attic, crawlspace, or mechanical space, and protect it with a barrier in areas like garages where it could be damaged.
