ACiQ 4 Ton Package Unit AC With 115000 BTU 81% AFUE Gas Furnace | 13.4 SEER2 Downflow / Horizontal Airflow | R454B

About this system

The ACiQ 4-Ton Package Unit combines a cooling system and a gas furnace in a single outdoor cabinet, making it a practical choice for homes that lack indoor mechanical space or rely on a single-point rooftop or ground-level installation. The 4-ton cooling capacity targets homes in the roughly 2,000 to 2,400 square foot range, though actual sizing depends heavily on climate, insulation, and local load calculations. Downflow and horizontal airflow configurations give installers flexibility across slab, rooftop, and crawlspace setups, which is a meaningful advantage over split systems in many commercial-residential or manufactured-home applications.

On the efficiency side, 13.4 SEER2 meets the current federal minimum for most of the country and is a step above the bare-code floor, though it sits well below premium 16-plus SEER2 territory. The gas furnace runs at 81% AFUE, meaning roughly 81 cents of every fuel dollar goes to heat, which is acceptable but noticeably below the 95-plus AFUE condensing furnaces found in higher-end package units. Buyers in mild heating climates or those primarily cooling will feel that trade-off less than those in cold northern regions. The system uses R-454B refrigerant, a lower global-warming-potential replacement for R-410A that is increasingly standard as the industry phases out older refrigerants.

What homeowners and pros say about ACiQ

Early owners of ACiQ package and split systems frequently highlight quiet operation and straightforward installation as standout positives, and the brand’s support team draws praise for responsiveness compared to what buyers might expect from a direct-to-consumer channel. That said, the honest caveat is that ACiQ is a relatively young brand, and Consumer Reports has not yet accumulated enough long-term field data to assign it a reliability ranking. That absence is not a red flag on its own, but it does mean buyers are working without the kind of independent reliability benchmarks available for Carrier, Trane, or Lennox units with decades of tracked data.

From a service and parts standpoint, the undisclosed manufacturer is a real practical concern for this specific unit. A technician arriving at a package unit installation may not immediately recognize the internal components or know which cross-referenced parts to pull from a distributor shelf, and that uncertainty can add time and friction to a service call. Because ACiQ sells direct rather than through a dealer network, there is also no single point of contact for coordinating warranty work the way a local dealer handles it for name brands. Buyers who have an established relationship with a willing independent HVAC contractor tend to report the smoothest ownership experience, while those who rely on whoever is available in an emergency have had more variable outcomes.

What it costs to run

At 13.4 SEER2, cooling this 4-ton system for a typical 1200-hour cooling season at the U.S. average electricity rate of $0.17/kWh works out to roughly $731 per year in cooling, about $0 less per year than a minimum-efficiency 13.4 SEER2 unit of the same size. Your real cost depends on your climate and local rate.

Method: (48,000 BTU/hr ÷ 13.4 SEER2) × 1200 hours ÷ 1000 × $0.17/kWh. Rate source: U.S. EIA average; cooling hours: moderate-climate estimate.
