ARCOAIRE EAA4X60L24A Evaporator A-Coil | 5 Tons

Five tons above a large electric furnace: the top of the EAA4X series

Arcoaire’s EAA4X series runs from 1.5 to 5 tons. The EAA4X60L24A A-coil sits at the top: 5 tons (60,000 BTU/h nominal) on R-410A, for electric furnaces and air handlers 24-1/2 in wide, according to the manufacturer’s nomenclature. It is the indoor part of a large central system, air conditioner or heat pump. It is available while supplies last, as Arcoaire now features the next generation of coils.

What you get

The R-410A thermostatic expansion valve (TXV) is factory-installed. The main tubes and fins are aluminum, with copper stubs for brazing the 3/8 in (liquid) and 7/8 in (suction) lines. The coil weighs 57.0 lb (26 kg) for shipping and installs vertically, in upflow or downflow. Arcoaire’s brochure declares it compatible with an air conditioner as well as a heat pump.

The plenum, where it all happens

The EAA4X60L24A is uncased. It does not come in a cabinet ready to bolt onto the furnace: it fits in the plenum, or in a suitable casing, not included. For a coil of this size, the existing plenum often has to be adapted. We measure the space using the spec sheet dimensions (A 31-1/16 in, B 23-5/16 in), then fabricate or modify the plenum so that all the furnace air passes through the coil, with sealed joints and access to the drain. This sheet metal work is part of the quote.

Matching a 5-ton system properly

This size is justified by a load calculation of the house, done during the estimate. The coil must then be matched with an R-410A outdoor unit of the same capacity; Arcoaire does not publish a matching list for this model, so we check the unit before ordering. Sold alone, the coil has no efficiency rating of its own and does not qualify for the LogisVert grant. With a heat pump, it also distributes heat in winter, and the electric furnace tops up in deep cold.

AirGreen takes care of it

AirGreen is a family business established in Montreal for more than fifteen years. Our RBQ licence 5645-9605-01 covers ventilation, refrigeration and electrical work: the plenum sheet metal, the refrigerant circuit and the connections are done by the same team. After a free estimate and a written quote, we set the coil, braze the lines, pressure-test and pull a vacuum, connect the drain and commission the system. We serve Montreal, Laval, Longueuil, the North Shore and the South Shore.
