Shopping for furnaces, boilers, and heating systems often comes down to the same tension: you want enough heating power for your home, and you also want a unit you can trust once it's installed. The ACiQ N80MSN1102120A is a gas furnace that checks the high-output box, but it's also an open-box item, so the trust question sits right at the center of this purchase.
Quick verdict
The ACiQ N80MSN1102120A is a single-stage, non-condensing gas furnace rated at 88,000 to 110,000 BTU. It includes a multi-speed ECM blower that can move up to 2,040 CFM. The price is listed at USD 625.00, and the condition is open box, never installed. If you're comfortable with an as-is unit, this furnace gives you a lot of heating capacity for that price.
Who it suits
This furnace makes sense for a homeowner or contractor who has already determined that a high-output unit is the right size. It also fits someone who wants a non-condensing furnace without the extra complexity of a condensing model. Because the unit is sold as-is, this is a better fit for a buyer who can handle the unknowns of an open-box product.
ACiQ N80MSN1102120A Gas Furnace 110,000 BTU 80% AFUE Multi-Speed ECM Open Box
The listed price for this ACiQ furnace is USD 625.00. It's described as an open-box unit that was never installed; the box was opened for inspection and verification only. The seller states the unit is complete and untested beyond a visual check, and the sale is as-is.
The furnace uses a single-stage, non-condensing design with 80% AFUE efficiency. Heating output is rated at 88,000 to 110,000 BTU. Venting is Category I, which is typical for this non-condensing furnace type. The multi-speed ECM blower stands out as a practical feature, since it can be adjusted to match the duct system and airflow needs. The cabinet measures 21"W x 29"D x 33-1/4"H, so potential clearance can be checked before the install.
One concrete reason to choose this unit is the combination of high output and a multi-speed ECM blower at a USD 625.00 open-box price. The main limitation is the condition: because it's an open-box, as-is furnace that has not been run-tested by the seller, you're accepting a unit that may need attention during the first proper setup.
Meaningful trade-offs
The open-box condition is the biggest trade-off. The unit has not been installed or powered up, so the actual operating behavior is unverified. That's not a problem if you're prepared to confirm everything during installation, but it's a real unknown compared with buying a brand-new, sealed furnace.
Efficiency is also part of the decision. At 80% AFUE, roughly 80% of the fuel becomes heat, while the rest is vented. A condensing furnace would capture more of that heat, but it would also be a different venting setup and usually a larger investment upfront. The 80% AFUE design here keeps the venting simpler.
As a single-stage furnace, this unit runs at full output until the thermostat satisfies. That's a straightforward operating mode, but it doesn't offer the two-stage or modulating comfort features that some newer furnaces include.
Bottom line
The ACiQ N80MSN1102120A is a solid match for a buyer who knows the home needs a big gas furnace and who is willing to take on the open-box, as-is condition. The high output is part of the package, and the open-box positioning is worth planning around.
