1.5 - 2 Ton Goodman R32 Horizontal Slab Coil, CSCT2412S3
The Goodman CSCT2412S3 is the most compact cased horizontal slab coil in Goodman's R-32 CSCT lineup, sized for 1½ to 2 ton split systems where the indoor coil lies on its side next to a horizontal furnace in an attic, crawlspace, or platform closet. A 25½" wide cabinet, factory-installed TXV, all-aluminum evaporator coil, and built-in R-32 leak detection sensor make it a smart pick for contractors and homeowners replacing a small-tonnage coil or building a new R-32 system around a matching outdoor condenser.
Is a 1.5 - 2 Ton Horizontal Slab Coil the Right Size?
The CSCT2412S3 carries a nominal 1½–2 ton rating, which lines up with outdoor units in roughly the 18,000–24,000 BTU/h range. It is the right coil when a load calculation calls for a smaller system and the furnace or air handler is installed horizontally, so the coil has to sit in line with the airflow rather than on top of the cabinet.
Tonnage is only part of the decision. Your home's heat gain, insulation, window area, duct size, and blower capability all affect whether a 2 ton match is enough. Goodman publishes pressure-drop data for this coil from 500 to 1,200 SCFM, and the 16" x 21" plenum opening should be checked against your existing supply duct transition before ordering.
Ideal for: Condos, apartments, small single-family homes, room additions, and attic or crawlspace furnace installs needing a compact 1½–2 ton R-32 horizontal coil.
Need more capacity? Step up to the 2 - 2.5 Ton Goodman R32 Horizontal Slab Coil, CSCT3012M3 for systems that need a wider 33½" cabinet and larger 7/8" suction connection.
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.

At just 35 pounds, the CSCT2412S3 is the lightest coil in the CSCT family, which makes a real difference when carrying it up an attic ladder or setting it on a platform. The 20" x 24" coil face sits inside a galvanized, foil-insulated cabinet with a factory-mounted TXV and R-32 sensor, so it arrives ready to braze in and wire to a compatible furnace.

Frequently Asked Questions
What size air conditioner pairs with the CSCT2412S3?
The CSCT2412S3 is rated for 1½ to 2 ton R-32 systems. Goodman requires the complete indoor and outdoor combination to be manufacturer approved and AHRI listed, so confirm the match with your outdoor unit before installation.
Is the CSCT2412S3 the smallest coil in the CSCT series?
Yes. It uses Goodman's S-size 25½" wide cabinet, the narrowest of the four CSCT models, and has the smallest 16" x 21" plenum opening.
What duct opening does the CSCT2412S3 connect to?
The plenum opening measures 16" wide by 21" high. If your furnace outlet is a different size, Goodman calls for a field-supplied transition to center the furnace and coil openings.
What line set sizes does the CSCT2412S3 use?
The coil has a 3/8" liquid connection and a 3/4" suction connection. Browse copper line sets and kits to complete the install.
How heavy is the CSCT2412S3 for an attic installation?
Goodman lists a ship weight of 35 lbs. The installation instructions recommend carrying the coil by the cabinet corners or with a hand truck so the piping is not damaged.
What airflow range is the CSCT2412S3 rated for?
Goodman's spec sheet lists wet and dry pressure-drop data for this coil from 500 to 1,200 SCFM. Set the furnace blower speed to deliver the airflow your outdoor unit requires within that range.
