Cased Coils

Built for residential and light commercial jobs, these factory-insulated indoor coils are ready to match with your condenser or heat pump. Contractors, property managers, and handy homeowners will find budget-friendly choices from $665 to $1124, backed by deep inventory to keep projects moving.

Use these coils for evaporator coil replacement, to correctly match an indoor coil to a new outdoor unit, to address refrigerant leaks by replacing the coil, or to configure airflow in horizontal or vertical installations. Choose standard cased A- or N-coils in vertical or multi-position cabinets, or select Horizontal Slab Coils when height is tight and a low-profile solution is required.

Select the right specs for your job: capacities from 1.5 to 5 tons to align with system BTU needs; cabinet widths in 14", 17.5", 21", and 24.5" to fit common furnace and air handler sizes; and refrigerant compatibility options including R-32, R-410A, and R-454B. Coils don’t carry a SEER2 rating on their own, but they are designed to be paired with SEER2-rated outdoor units for compliant, efficient performance when properly matched.

Frequently Asked Questions

  • How do I choose the correct tonnage cased coil to match my outdoor unit?

    Match the coil’s nominal tonnage to the condenser or heat pump. Some pairs allow slight upsizing, but always verify the manufacturer or an AHRI-rated match for best performance.

  • Which refrigerant type (R-32, R-410A, R-454B) should I select for my existing system?

    Use a coil that matches your outdoor unit’s refrigerant. Do not mix refrigerants; R-32 and R-454B (A2L) require compatible outdoor units, metering devices, and procedures.

  • What cabinet width do I need for my furnace or air handler?

    Measure the appliance cabinet and choose a coil width to match it-typically 14", 17.5", 21", or 24.5". A proper fit ensures correct airflow and sealing.

  • Should I use a horizontal, vertical, or multi-position coil for my installation?

    Match the coil to your airflow orientation. Multi-position models cover upflow, downflow, and horizontal; horizontal slab coils are ideal where height is limited.

  • Are these cased coils compatible with heat pump systems as well as AC condensers?

    Yes-select a heat pump-rated coil and the correct metering device (TXV or piston) specified for your system.

  • Do I need a licensed contractor to braze and charge the system when replacing a coil?

    Yes. A licensed, EPA 608-certified technician must recover refrigerant, braze with nitrogen purge, evacuate, and charge the system.

  • Can I replace an R-410A coil with an R-32 or R-454B coil without changing other components?

    No. A2L refrigerants require matched outdoor units and compatible parts. Plan a matched-system upgrade.

  • What is the difference between standard cased coils and horizontal slab coils?

    Standard cased coils are taller A- or N-coils for vertical or multi-position use; slab coils are low-profile for dedicated horizontal applications.

  • What comes with a cased coil?

    An insulated cabinet, drain pan, and coil assembly. Some models include a factory TXV or piston; check the model’s specification details.

  • Can these coils be used in light commercial applications?

    Yes. Many 3-5 ton models are suitable for small offices or retail spaces when matched to the load and local codes.
