3.5 Tons

The ACiQ FJMA4X42L0CB air handler is rated for an output of 3.5 tons. In many cases, this air handler will be larger in tonnage than the condenser it is paired with to maintain the unit's overall efficiency. Please note that for this unit to provide cooling, an outdoor condenser is required for it to function. The unit can support electric heating as a straight electric furnace or as a backup for a heat pump, offered at an additional cost to be field installed.


ACiQ offers a 5 year no hassle replacement warranty, as well as a 10 year parts warranty on this unit. For these warranties to be upheld, the unit must be installed following your state and local codes, a new and certified coil must be installed at the same time, and the entire system must be registered online through the manufacturer. After your purchase, a representative will reach out to you to retrieve installation information so we can register the product for you.

Installation and Durability

To make a more versatile unit, ACiQ designed the FJMA4X42L0CB to easily be installed in an upflow, downflow, or horizontal position. A TXV kit is already installed on the unit so your installer does not have to install one, decreasing installation costs. For durability, the FJMA4X42L0CB air handler is designed with an extremely strong, one-piece outer casing to protect the unit, and the coil is designed with corrosion-resistant aluminum.

Intelligent Comfort

The FJMA4X42L0CB air handler has an efficient 5-speed ECM blower motor, providing a more stable temperature in your home, making you more comfortable. The control board will automatically communicate with your thermostat to adjust the output of the blower to suit your needs. With this intelligent comfort and efficiency, the FJMA4X42L0CB meets ACiQ's superior standards.
