  • R454B Refrigerant Compatibility: The ACiQ-12-AHD air handler is compatible with R454B refrigerant, a more environmentally friendly and energy-efficient refrigerant choice, reducing your system’s carbon footprint.

Installation and Maintenance

Installing the ACiQ central ducted air handler is similar to installing any standard replacement air handler. Your technician will handle the electrical, refrigerant, thermostat, and communication connections, as well as linking the air handler to your return and supply ductwork. This unit is highly versatile, as it is multi-positional—capable of being installed in upflow, downflow, or horizontal orientations.

The system can be controlled by any 24V thermostat with two stages of heating, and supplemental electric heat kits are available for backup heating during the coldest days. Should maintenance be necessary, the intelligent control board in the air handler will display fault codes to help identify any issues with the system.

Please Note: For proper operation, the air handler must be paired with a condenser and other installation equipment, which are sold separately if not included in the product bundle. Additionally, if you wish to use straight electric heating, an electric heat kit is required, which is also available at an additional cost.

very reliable company and great prices

Bought a few units from this company and they were very friendly and easy to work with. Either matched prices or beat the price and had fast shipping also.

Excellent company to purchase from

I wasn’t to sure about if this company could deliver it quickly but it arrived within a week. No issues. I needed this one for parts as my first one that I installed a year ago had the ecm go out on the blower fan. Parts are hard to come by for this Chinese brand. I think the ecm went out due to condensation in the main supply plenum dripping onto fan motor. I do like this ac unit but hope the fan lasts longer than a year. I covered the fan ecm with flex seal tape.

Goodman 5 Ton System

Excellent value, customer sales support (a human called to confirm online order... greatly appreciated!), fast shipping. Very happy customer.

A + Company

Sale representative Lopez was very experienced and professional. I would recommend this company to any one and I am looking forward to work with Lopez again.
