When you need a reliable replacement evaporator coil for your AC unit, the Trane 2 – 3 Ton 30000 BTU A4MX Four Way Cased Coil A4MXB1832AC6HA delivers maximum heat transfer and exact fitment. Built with an exclusive all-aluminum Comfort coil, this unit solves the biggest durability problem with indoor HVAC components. If you compare a Trane all aluminum coil vs copper options, the aluminum design actively prevents formicary corrosion and stops costly refrigerant leaks. Matching this exact coil to your existing furnace and outdoor AC unit instantly improves your overall system efficiency. Routine maintenance is also straightforward since the internal design allows for quick and easy cleaning.
Before you buy your Trane A4MX cased coil, verify your existing furnace width to ensure a perfect match. The Trane 17.5 inch cased coil dimensions provide an exact, gap free fit for standard B-cabinet installations. Inside, the 30000 BTU A4MX 4 Way cased coil features 100% foil-backed insulation. This internal lining dampens operating noise and gives technicians a smooth surface to wipe down. To protect your home from moisture damage, the two way noncorrosive drain pan prevents water from sitting inside the unit. Finally, the exterior of this 2 ton to 3 ton unit is sealed with a heavy duty painted finish that safeguards the metal cabinet from rust and corrosion in damp environments.
