About this system
The ACiQ G97CMN1202422B is a 120,000 BTU, 97% AFUE modulating gas furnace designed for larger homes in cold climates where heating efficiency and precise comfort control matter most. At 97% AFUE, it converts 97 cents of every dollar of natural gas into usable heat, placing it squarely in the top tier of residential gas furnace efficiency. The variable-speed blower and modulating gas valve work together to adjust heat output and airflow in small increments rather than cycling on and off at full blast, which translates to steadier indoor temperatures, quieter operation, and lower utility bills compared to single-stage or two-stage equipment.
The multi-positional design means it can be installed upflow, downflow, or horizontal, giving installers flexibility in attics, basements, closets, and crawl spaces. The R-454B refrigerant compliance label on this furnace is mostly relevant when it is paired with a matched cooling system, signaling that ACiQ is building toward the low-GWP refrigerant transition already underway in split systems. At 10 tons of equivalent heating capacity, this unit is sized for homes roughly in the 2,800 to 4,500 square foot range depending on climate zone, insulation, and local heat loss calculations. Proper Manual J load sizing before purchase is essential, since oversizing a modulating furnace still causes short-cycling and comfort problems.
The ACiQ G97CMN1202422B delivers genuine top-tier efficiency and variable-speed comfort at a price point that undercuts most name-brand equivalents by a meaningful margin, making it a strong option for budget-conscious buyers who are comfortable sourcing their own installer. The trade-off is real: ACiQ is a newer brand with limited long-term reliability data, an undisclosed manufacturer, and no factory dealer network to fall back on if service gets complicated.
Overall score is the average of the five ratings above.
What we like
- 97% AFUE places it among the most efficient residential gas furnaces available
- Modulating burner and variable-speed blower deliver noticeably quieter, more even heating than single- or two-stage units
- Multi-positional cabinet adds installation flexibility across common residential configurations
- 12-year parts warranty ships with the unit and is not inflated by dealer markups
- Direct-to-consumer pricing typically lands well below comparable-spec name-brand furnaces
Trade-offs
- No long-term independent reliability data exists; Consumer Reports does not yet rank ACiQ
- The undisclosed manufacturing origin complicates parts sourcing and cross-referencing service history
- No factory dealer network means you are responsible for vetting your own installer and service contractor
- Modulating furnaces are more complex to diagnose and repair than single-stage units, which raises the stakes if a local tech is unfamiliar with the controls
What homeowners and pros say about ACiQ
Early owner feedback on ACiQ gas furnaces follows a consistent pattern: buyers highlight noticeably quiet operation once the variable-speed blower settles into steady-state, and several report that setup and first-season performance met or exceeded expectations. ACiQ’s customer support line receives positive mentions in independent forums for responsiveness, which matters when you are buying direct without a dealer buffer. That said, Consumer Reports does not yet rank ACiQ because the brand is too new to have generated the long-term reliability sample size the organization requires, so the optimistic early reviews carry a caveat that they reflect short ownership windows rather than multi-year durability data.
For HVAC contractors, the undisclosed manufacturer is the most common point of hesitation. Technicians who suspect a connection to the ICP and Carrier family say the controls and components look familiar, but without confirmed documentation, cross-referencing a failed part or pulling a service bulletin from a parent brand’s database is not straightforward. The direct-sale model also means there is no factory-trained dealer channel: the tech you hire is working from whatever documentation ACiQ provides, not a manufacturer training program. On a modulating furnace with an ECM blower and a two-stage or modulating gas valve, that gap matters more than it would on a simple single-stage unit, since diagnostics are more involved when something eventually does need attention.

Questions about this system
Who actually manufactures this furnace, and does it matter for parts availability?
ACiQ does not publicly disclose its manufacturing source, though forum discussion points toward the ICP and Carrier family of manufacturers without confirmation. It does matter practically: because the origin is unconfirmed, a service technician cannot easily cross-reference parts catalogs from a known parent brand, which can slow down repairs compared to a furnace from a brand with a fully transparent supply chain.
Is 120,000 BTU the right size for my home?
Furnace sizing depends on your home's heat loss calculation, not square footage alone. As a rough guide, 120,000 BTU input covers larger homes in cold climates, but a licensed HVAC contractor should run a Manual J load calculation before you buy. Oversizing a modulating furnace reduces the efficiency and comfort benefits the variable-speed system is designed to deliver.
Can any licensed HVAC contractor install and service this furnace, or does it require a factory-authorized tech?
Any licensed HVAC contractor can install it, and there is no factory dealer network requirement. The practical challenge is that some independent contractors are less familiar with ACiQ controls and diagnostics than they are with Carrier or Trane equipment, so asking your installer about their experience with the brand or with similar modulating furnaces from the ICP family is a reasonable step before hiring.
What does the 12-year warranty actually cover, and are there registration requirements?
ACiQ advertises a 12-year parts warranty, and because the unit is sold direct, that coverage is not reduced by dealer markups or split into shorter base and extended tiers. You should confirm registration requirements directly with ACiQ at purchase, since warranty terms can require timely registration to be valid and conditions can change.
Why does this furnace mention R-454B if it is a gas furnace with no refrigerant?
The R-454B compliance notation signals that this furnace is designed to be paired with split-system cooling equipment that uses the new lower-GWP R-454B refrigerant, meaning the coil and controls are compatible with that refrigerant transition. If you are buying the furnace as a standalone heat-only system, the refrigerant designation has no effect on furnace operation or efficiency.
