Coils

The evaporator coil is the part of your system that actually makes cold air. Sitting indoors above the furnace or inside the air handler, it holds the refrigerant that absorbs heat from the air blowing across it, which is why a worn or leaking coil shows up as weak cooling and rising bills long before anything else fails. We stock evaporator coils because replacing this single component, when it is the part that has gone, is often the difference between a targeted repair and an unnecessary full-system replacement.

This collection covers cased A-coils from Goodman and ACiQ, sized from 1.5 to 5 tons, built with all-aluminum construction and factory-installed thermostatic expansion valves for precise refrigerant metering. Every coil here is R-32 compatible, matching the current generation of refrigerant in new equipment. The one rule that governs coil selection is matching: the coil has to suit your system's tonnage, refrigerant, and airflow direction, and our team is here to help you confirm that fit before you buy.

Best Evaporator Coils for...

Coil-Only Replacements

The best evaporator coil for a coil-only replacement is one matched to your existing condenser's tonnage, refrigerant, and SEER2 rating. Homes with a relatively new outdoor unit and a failed indoor coil benefit from this targeted fix. Confirm the match before buying, since a mismatch undercuts efficiency.

Upflow and Downflow Furnace Pairings

The best evaporator coil for a furnace pairing is a cased A-coil in the orientation your system uses, upflow or downflow. Installations sitting above or below a gas furnace need the coil oriented to the airflow direction. A versatile upflow/downflow cased coil suits most furnace layouts.

Horizontal Air Handler Installs

The best evaporator coil for a horizontal install is a horizontal-configured cased coil matched to the air handler. Attic and crawlspace systems that run airflow sideways rely on this orientation. Confirm the coil's dimensions fit the available space before ordering.

High-Capacity Systems

The best evaporator coil for a high-capacity system is a 4 to 5 ton cased coil sized to a larger condenser. Bigger homes and light commercial spaces running higher tonnage need a coil that matches that output. A 5-ton coil anchors the top of this range.
