  • 48,000 BTU / 4 Ton Capacity – Delivers efficient and reliable heating and cooling for medium to large-sized homes

  • Variable Speed DC Blower Motor – Ensures ultra-quiet operation, consistent airflow, and enhanced energy efficiency

  • 24V Thermostat Compatible – Fully compatible with any conventional or smart 24V thermostat

  • Multi-Positional Installation – Flexible mounting options: upflow, downflow, or horizontal left/right configurations

  • R454B Refrigerant Compatible – Eco-conscious design supports next-generation refrigerants for long-term sustainability

  • Communicating Capable – Pairs with inverter condensers to optimize performance and adjust BTU output dynamically

  • Dependable HVAC Solution – Ideal for new installs or upgrading existing central air systems

Installation and Maintenance

Installing the ACIQ central ducted air handler is straightforward and similar to replacing a standard air handler. Your HVAC technician will handle all necessary connections, including electrical, refrigerant lines, thermostat wiring, and system communication links. The unit also connects directly to your existing return and supply ductwork.

Thanks to its multi-positional design—compatible with upflow, downflow, or horizontal configurations—this air handler offers flexible installation options to suit a variety of spaces. It can be controlled by any 24V thermostat that supports two stages of heating.

For added comfort during colder weather, optional supplemental electric heat kits are available as a backup heat source. If maintenance is ever required, the built-in intelligent control board displays diagnostic fault codes to help quickly identify and resolve issues.

Please note: This air handler must be paired with a compatible condenser and other required installation components, which may be sold separately if not included in your product bundle. To enable electric-only heating, an electric heat kit (sold separately) is required.

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
