  • Inverter-Ready Communication – Optimizes efficiency when paired with inverter condenser systems for modulating BTU output

  • Great for New Installs or System Upgrades – Reliable choice for replacing older units or building a new HVAC setup

Installation & Maintenance

The installation of the ACiQ central ducted air handler closely mirrors that of any standard replacement air handler. A certified technician will handle all essential connections, including electrical, refrigerant lines, thermostat wiring, and communication links. The unit is then connected to your existing return and supply ductwork to ensure efficient airflow throughout your home.

With a multi-positional design—supporting upflow, downflow, and horizontal configurations—this air handler offers maximum installation flexibility. It’s compatible with any 24V thermostat that supports two stages of heating, allowing for easy integration into most systems.

For colder climates, optional supplemental electric heat kits provide reliable backup heating. And for ongoing reliability, the intelligent control board is equipped with fault code diagnostics, helping to quickly identify and address any system issues during maintenance.

Please Note: This air handler requires installation with a compatible condenser and other necessary system components, which may be sold separately if not included in your package. To use electric-only heating, a dedicated electric heat kit is also required and 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.
