ACiQ 4 Ton Multi-Speed and Multi-Positional Air Handler for Flexible Installation –208/230V 1-Phase 60Hz

The FJM series from ACiQ is a key part of their air handler lineup, offering great flexibility and efficiency. Each model comes with a 5-speed ECM blower motor that adjusts easily to different air conditioning needs, helping to maintain comfort while saving energy. The system also includes a thermal expansion valve (TXV) that’s installed at the factory. This component improves how well the system controls temperature, making it more responsive and precise in various situations.

For colder areas or places that need extra heat, electric heat kits can be added to any model for an extra charge. This option lets you customize the heating setup, adding more flexibility and convenience in one package.

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

A + Company
