Quick facts
The largest size in the FJMA4X series, for very large spaces
Five tons: which buildings
The FJMA4X60L0DB is the 5-ton (60,000 BTU/h) air handler of Arcoaire’s FJMA4X series, and the largest in the range. Arcoaire publishes a nominal airflow of 1,750 CFM for it. It is found in very large homes, in houses extended several times and in small commercial spaces or offices served by ducts, wherever the load calculation reaches 5 tons.
It works with an outdoor unit of the same capacity, a central heat pump or central air conditioner, chosen from the manufacturer’s matches. The air handler is sold alone: the outdoor unit is not included.
Height first
At 59-3/16 in high, 24-11/16 in wide and 22-1/16 in deep, it is a sizeable unit. In many basements in Montreal and Longueuil, the clear height below the joists decides the location before anything else, because the plenum and duct connections also have to fit. We measure these spaces during the estimate, along with the service clearance the manufacturer requires.
The air handler runs on 208/230 V single phase, 60 Hz. Arcoaire publishes a 7.6 A minimum circuit ampacity and 15 A maximum overcurrent protection. The liquid connection is 3/8 in (9.5 mm), inside diameter.
One system or two
Beyond a certain size, the real question is no longer the air handler size but how to distribute the air. A single 5-ton system keeps installation and maintenance simple; two smaller systems sometimes serve better a house whose floors have very different needs. We present both options when the house lends itself to it, and we check that the main ducts and return air can handle 1,750 CFM nominal.
Installation and conditions
Sold alone, the air handler does not qualify for the LogisVert grant: the grant follows the certified outdoor unit + air handler pair. No heater kit is described for this model in the data we verified; for electric backup heat, we confirm the compatible kit before ordering.
AirGreen is a family business established in Montreal for more than fifteen years, holding RBQ licence 5645-9605-01 in ventilation, refrigeration and electrical work. After the free estimate and written quote, our technicians remove the old unit, install the air handler, adapt the plenum, connect the refrigerant piping, the condensate drain and the electrical supply, pull a vacuum and commission the system. We install in Laval, on the South Shore, on the North Shore and throughout Greater Montreal.

Frequently asked questions
Will the cabinet fit under my basement joists?
It is 59-3/16 in high, not counting the plenum. In a low basement, that measurement is checked first; we take it during the free estimate.
Is one 5-ton system better than two smaller ones?
It depends on the house. A single 5-ton air handler keeps the installation simple; two systems sometimes distribute air better between very different floors. We compare both options in the quote.
What power supply is needed?
208/230 V single phase, 60 Hz, with a 7.6 A minimum circuit ampacity and 15 A maximum overcurrent protection for the air handler, per Arcoaire.
Is the outdoor unit supplied?
No. The air handler is sold alone; we choose a 5-ton outdoor unit with you from the manufacturer’s matches. Sold alone, the air handler does not qualify for the LogisVert grant.
