Allied Air 29a86 Cased Evaporator Coil 4 Ton Upflow R-410A

Product Description

The ALLIED AIR 29a86 is a cased upflow evaporator coil rated for 3.5 to 4 nominal tons and designed for use with R-410A refrigerant systems. Built with an aluminum coil construction, this evaporator coil is the indoor heat-exchange component responsible for absorbing heat from return air before it circulates back through the conditioned space. The coil ships in an enclosed casing, simplifying installation into upflow air handler and furnace-based systems. It is sized to match a 21-inch cabinet opening and is typically installed by licensed HVAC technicians as part of a split-system cooling or heat pump installation.

This coil is suited for residential upflow split-system applications where R-410A refrigerant is required. It is designed to pair with compatible condensing units in the 3.5 to 4 ton capacity range. The cased design allows direct placement in the supply plenum above a gas furnace or air handler in upflow configurations, making it a common choice for residential central air conditioning installations where indoor cabinet space and refrigerant line sizing are standard considerations.

Key Features

• Nominal capacity of 3.5 to 4 tons for flexible system matching
• R-410A refrigerant compatible — no retrofit modifications required
• Upflow cased design for straightforward plenum integration
• Aluminum coil construction for corrosion resistance and efficient heat transfer
• 3/8 inch liquid line and 7/8 inch suction line connections
• 10-year limited warranty from the manufacturer

Compatibility

Designed as an OEM-style cased evaporator coil for upflow R-410A split-system installations in the 3.5 to 4 ton capacity range. Compatible system pairings should be verified against the manufacturer published equipment matching tables.

Installation Notes

Installation of this evaporator coil must be performed by a licensed HVAC technician in compliance with local mechanical codes and EPA Section 608 regulations governing refrigerant handling. Disconnect and lock out all electrical power to the air handling equipment before beginning coil removal or installation. Ensure the suction and liquid line connections are properly brazed and leak-tested before recharging the system with R-410A. Confirm that the indoor cabinet width accommodates the coil dimensions prior to installation.
