2.5 - 3 Ton

These cased evaporator coils are built to pair with 2.5-3 ton condensers and heat pumps in residential and light commercial applications. Choose from cabinet widths of 14", 17.5", and 21" to fit common furnace and air handler plenums, and select Horizontal, Vertical, or Multi-Position models to match your airflow orientation and space constraints.

Whether replacing a leaking or mismatched indoor coil, or upgrading to ensure proper refrigerant compatibility, you’ll find models for R-32, R-410A, and R-454B systems. Coils in this class support typical BTU loads for 2.5 and 3 tons, with selected units rated 3 - 3.5 tons to provide flexibility when your outdoor unit or ductwork benefits from a slightly larger coil.

These coils are designed for today’s efficiency standards and can be matched to SEER2-rated outdoor units when properly configured with the correct metering device (TXV) and line set sizing. Price points from $745 to $1,543 keep projects budget-friendly without sacrificing reliability.

Installers and capable DIYers appreciate factory-cased construction for a clean, insulated finish, easy access panels, and drain pan designs suited for multiple orientations. Always verify cabinet width, refrigerant type, and airflow direction before ordering to ensure a seamless fit and optimal performance.

Frequently Asked Questions

  • How do I choose the correct cased coil size for a 2.5 or 3 ton system?

    Match the coil tonnage to your outdoor unit. A 2.5 or 3 ton coil is typical; some 3 - 3.5 ton coils are approved to pair with 3 ton condensers for better efficiency and airflow.

  • Which refrigerant coil (R-32, R-410A, or R-454B) matches my existing outdoor unit?

    Use the same refrigerant as your condenser or heat pump. Mixing refrigerants is not permitted; select a coil specifically labeled for R-32, R-410A, or R-454B.

  • What cabinet width (14, 17.5, or 21 inches) will fit my furnace or air handler?

    Measure the supply plenum or furnace top. Choose a coil cabinet width that matches 14", 17.5", or 21" to avoid transition pieces and airflow restrictions.

  • Should I select horizontal, vertical, or multi-position for my installation?

    Pick the orientation that matches your ductwork and drain layout. Multi-position coils offer flexibility when access or space is tight.

  • Can these cased coils be used with heat pumps as well as AC condensers?

    Yes. Most models are approved for both cooling-only condensers and heat pumps when matched and metered correctly.

  • Are there any additional components needed when replacing only the indoor coil?

    Often a TXV matched to your refrigerant and tonnage is required. Plan for line set flushing, filter-drier replacement, nitrogen purging, and a new drain connection.

  • Will a 3 - 3.5 ton rated coil work with a 3 ton condenser?

    In many cases yes, if the manufacturer approves the match. A slightly larger coil can improve efficiency and comfort when properly configured.

  • Do these coils support SEER2 systems?

    Yes. When paired with a compatible SEER2 outdoor unit and correct metering device, they meet performance requirements.

  • Is professional installation required?

    Yes. Refrigerant handling and warranty compliance require installation by a licensed HVAC professional.

  • Are these coils suitable for light commercial applications?

    Yes. Many 2.5-3 ton cased coils serve small offices and retail spaces when ducting and load calculations support the capacity.
