About this system
The ACiQ N80MSN0701712A is a 66,000 BTU, 80% AFUE multi-positional gas furnace built around an 18-speed ECM (electronically commutated motor) blower. That motor distinction matters: unlike a single-speed or two-stage furnace that blasts on at full capacity and shuts off, the ECM blower modulates airflow continuously, meaning quieter operation, more even temperatures room to room, and meaningfully lower electricity consumption from the air-handling side. At 80% AFUE, roughly 20 cents of every dollar in gas is vented as exhaust, which is the minimum efficiency tier allowed under current federal standards for most northern climate zones and a step below the 90%-plus condensing furnaces that qualify for efficiency rebates in many states.
The multi-positional cabinet means it can be installed in upflow, downflow, or horizontal orientations, which gives installers flexibility in tight mechanical rooms, closets, or attic and crawlspace applications. At 66,000 BTU it sits in a mid-range output class suited to homes roughly in the 1,400 to 2,200 square foot range depending on climate zone, insulation, and Manual J load calculation. This is an honest fit for a budget-conscious buyer replacing an aging 80% furnace in a moderate-to-warm climate where upgrading to a 96% condensing unit would require new PVC flue runs and higher upfront cost that the energy savings may not recover before the equipment lifecycle ends.
The ACiQ N80MSN0701712A delivers a genuinely capable ECM-equipped furnace at a price that undercuts established brands by a noticeable margin, and the 12-year warranty is competitive with anything in this class. The honest trade-off is that the brand is new enough that long-term reliability data does not yet exist, and buying direct rather than through a dealer network means your service experience depends entirely on whoever you hire locally.
Overall score is the average of the five ratings above.
What we like
- 18-speed ECM blower reduces operating noise and electricity draw compared to PSC-motor furnaces at this price point
- Multi-positional cabinet suits a wide range of installation configurations without buying a dedicated unit
- 12-year parts warranty ships standard with no dealer markup inflating the price
- 80% AFUE uses standard B-vent or metal flue, avoiding the cost of rerouting to PVC condensate drain required by 90-plus units
- Early owner feedback consistently notes quiet operation and responsive customer support from AC Direct
Trade-offs
- 80% AFUE is the federal minimum for many northern zones and will not qualify for most utility rebate programs that require 95% AFUE or higher
- The actual manufacturing origin is not publicly disclosed, which complicates parts cross-referencing and makes some independent technicians cautious about service
- No established dealer network means warranty labor scheduling falls entirely on the homeowner to arrange with an independent contractor
- Consumer Reports has not yet ranked ACiQ due to insufficient long-term field data, so reliability confidence rests on early reviews rather than actuarial history
What homeowners and pros say about ACiQ
Owners who have installed the ACiQ furnace line early on consistently highlight how quiet the ECM blower runs compared to their previous equipment, and AC Direct’s direct-sale support channel gets repeated praise for responsiveness. That positive early signal is worth noting, but it should be weighed honestly: these are short-tenure impressions, not the kind of multi-year reliability record that Consumer Reports builds its scores from, and ACiQ does not yet appear in those rankings due to insufficient long-term data. For a homeowner comfortable buying direct and managing their own service contractor relationships, that early feedback is encouraging. For someone who wants the reassurance of a ranked reliability history, the data simply is not there yet.
Independent HVAC technicians have a mixed but mostly practical reaction to the brand. The undisclosed manufacturing origin is the most commonly cited friction point: without confirmed OEM lineage, a tech cannot as easily cross-reference parts histories or draw on institutional familiarity the way they can with a Carrier or Trane unit. Some contractors are candid that they prefer to work on equipment they know, which is a real consideration for warranty service scheduling. On the other hand, the ECM motor technology itself is not exotic and is serviceable by any competent technician. The absence of a dealer network also means no factory-authorized labor markup, which is part of why the unit is priced where it is. Whether that trade-off works depends almost entirely on how strong your local independent HVAC contractor relationships are before you buy.

Questions about this system
Will this furnace work with my existing metal flue and B-vent, or do I need new venting?
Yes. As an 80% AFUE non-condensing furnace it exhausts through a standard metal flue or B-vent at high enough temperatures to prevent condensation, so you do not need to run new PVC pipes or add a condensate drain. Verify the existing flue diameter matches the unit's outlet spec before installation.
What does the 18-speed ECM blower actually mean for day-to-day comfort versus a standard furnace?
An ECM motor ramps airflow up and down in small increments rather than switching between a handful of fixed speeds, which reduces the temperature swings and air-rushing noise associated with conventional furnaces. It also draws significantly less electricity than a permanent-split capacitor (PSC) motor during lower-demand operation, which shows up modestly on your electric bill over a heating season.
The 12-year warranty sounds good, but how do I actually use it if something fails?
ACiQ sells direct through AC Direct, so warranty claims go through their customer support rather than a local dealer. You are responsible for hiring a licensed independent HVAC contractor to do diagnostic and repair work; you then submit for parts coverage. Labor is not covered, which is standard across virtually all furnace warranties at this price tier.
Is this furnace large enough for my 2,000 square foot home in a cold climate?
At 66,000 BTU it can work for a reasonably insulated 2,000 square foot home in a moderate climate, but a proper Manual J heat load calculation is the only reliable answer for your specific house, insulation level, window area, and local design temperature. Oversizing a furnace causes short-cycling and humidity problems, so do not skip that calculation.
Since ACiQ is a newer brand without Consumer Reports data, how do I assess the risk before buying?
The honest picture is that long-term reliability data does not yet exist for ACiQ, and Consumer Reports has not ranked it. Early owner reviews are largely positive, and forum speculation (unconfirmed) links the hardware to a major OEM manufacturer. The 12-year parts warranty limits your financial exposure on components, but you carry more uncertainty on reliability than you would with a brand that has a decade of Consumer Reports data behind it.
