About this system
The ACiQ G97CMN0801714A is an 80,000 BTU, 97% AFUE modulating gas furnace designed for homeowners who want near-top-tier efficiency without paying a premium-brand price. A 97% AFUE rating means roughly 97 cents of every dollar spent on natural gas becomes usable heat, which places this unit among the most efficient furnace tiers available and makes it eligible for federal tax credits under the Inflation Reduction Act’s high-efficiency heating equipment provisions. The variable-speed, modulating burner is the defining feature: instead of simply switching on at full blast, it adjusts both the flame and the blower continuously to match actual heating demand, which reduces temperature swings, lowers operating noise, and cuts fuel consumption during the milder shoulder-season days that account for most of a furnace’s annual runtime.
The communicating control board means this furnace is built to talk to a compatible communicating thermostat and air handler, exchanging real-time performance data rather than relying on simple on/off signals. That integration can improve comfort and diagnostics, but it also means you will get the most out of this unit when it is paired with compatible ACiQ or other communicating-protocol equipment. The multi-positional cabinet allows upflow, downflow, or horizontal installation, which gives installers flexibility in tight utility rooms, crawl spaces, and attic applications. This unit suits homes in cold-to-moderate climates where a high-efficiency gas furnace carries a clear payback over a standard 80% unit, and where the homeowner is comfortable buying direct and sourcing their own qualified HVAC contractor for installation and future service.
The ACiQ G97CMN0801714A delivers genuine 97% AFUE modulating performance at a price that undercuts established brands by a meaningful margin, making it a strong option for cost-conscious buyers who can find a qualified independent contractor. The trade-off is a shorter track record than Carrier or Trane and an undisclosed manufacturing origin that can complicate parts sourcing if something goes wrong years down the line.
Overall score is the average of the five ratings above.
What we like
- 97% AFUE puts it in the top efficiency tier, minimizing long-term fuel costs
- Modulating burner and variable-speed blower together produce noticeably quieter, more even heat than staged units
- Multi-positional cabinet gives installers flexibility in tight or unconventional equipment spaces
- 12-year parts warranty ships with the unit and requires no dealer markup or registration fee
- Early owner feedback consistently highlights responsive ACiQ support and quieter-than-expected operation
Trade-offs
- Manufacturer identity is not publicly disclosed, which makes cross-referencing parts, service bulletins, and long-term reliability data harder than with a name brand
- No dealer network means installation and service depend entirely on finding an independent contractor willing to work on a direct-sale brand
- Consumer Reports has not yet ranked ACiQ due to insufficient long-term field data, so reliability over a 10-15 year lifespan is still unproven
- Communicating system requirements mean pairing it with non-compatible equipment can limit functionality and complicate setup
What homeowners and pros say about ACiQ
Early owners of ACiQ furnaces frequently cite quieter-than-expected operation and responsive customer support as standout positives, and those themes hold for the high-efficiency modulating models in particular. Because the brand is relatively new to the market, Consumer Reports has not yet assigned it a reliability score due to insufficient long-term data, which is an honest gap worth acknowledging. HVAC forum discussions often circle around the undisclosed manufacturing origin as both a selling point and a risk: the speculation that ACiQ equipment shares a production line with better-known brands is appealing on price grounds, but because it remains unconfirmed, contractors cannot easily pull up service histories, cross-reference OEM parts, or rely on established repair procedures the way they can with a Carrier or Trane unit.
On the installer side, contractors who have worked with direct-sale brands point out that the absence of a dealer network is a real practical issue for this furnace specifically. A communicating, modulating gas furnace is not a straightforward installation: it requires proper commissioning of the variable-speed blower, correct setup of the communicating controls, and careful attention to venting for a 97% AFUE condensing unit. Finding an independent contractor experienced with communicating systems and willing to install a direct-purchase unit takes more legwork than calling the nearest authorized dealer. The 12-year parts warranty is genuinely strong for the price tier, but labor is not covered, and if the manufacturing origin remains undisclosed, sourcing an obscure replacement part outside of ACiQ’s own supply chain could be frustrating in a worst-case scenario a decade from now.

Questions about this system
Does the communicating feature require a specific thermostat, and what happens if I use a standard non-communicating thermostat?
The communicating board is designed to work with compatible communicating thermostats that exchange two-way data with the furnace. If you use a standard non-communicating thermostat, the furnace will typically still operate, but you lose the advanced diagnostics and optimized control that make the communicating setup worthwhile. Confirm thermostat compatibility with ACiQ or your installer before purchasing.
Who actually manufactures this furnace, and will I be able to find parts in 10 years?
ACiQ does not disclose its manufacturing partner, though forum speculation points to the ICP and Carrier family of manufacturers. That connection is unconfirmed, so you cannot reliably cross-reference parts catalogs. ACiQ has stated it maintains parts availability for its product lines, but given the brand's short history, long-term parts supply is a legitimate open question.
Is this furnace eligible for the federal high-efficiency heating tax credit?
As of 2024, gas furnaces at 97% AFUE qualify for the federal Energy Efficient Home Improvement Credit (25C), which can offset a portion of the equipment and installation cost. You should verify current IRS eligibility requirements and keep your purchase and installation documentation, and consulting a tax professional is advisable since credit rules can change.
Will any licensed HVAC contractor install this, or will some refuse because it is a direct-sale brand?
Some contractors are reluctant to install equipment they did not supply because it removes their equipment margin and can create liability questions if something goes wrong. It is worth calling ahead and being upfront that you purchased the unit direct. Many independent contractors will install it, but expect that some dealers tied to specific brands may decline.
How does the 12-year warranty work when there is no dealer network?
ACiQ's 12-year parts warranty is handled directly through the company rather than through a dealer, which is actually simpler in some respects because there is no middleman markup or dealer registration requirement. If a covered part fails, you work with ACiQ's support team to obtain the replacement part, and then a contractor installs it. Labor costs are not covered by the warranty, so budget for those separately.
