Choosing among furnaces, boilers, and heating systems comes down to more than choosing the largest number in a title. In this group, the decision is between a higher-efficiency, higher-capacity ACiQ furnace, two identically specified Johnson Controls listings at different prices, and an open-box ACiQ single-stage furnace. Start with the heating rating and operating setup your system calls for, then weigh efficiency, condition, and listed price.
Quick take
- The 120,000 BTU 96% Propane/Natural Gas Furnace Multi-Positional 1-Stage 9-Speed R32 is the choice for shoppers focused on the listed 95-96% AFUE range and a 120,000-120,999 BTU heating rating.
- The two Johnson Controls TM8V080C16MP12C 80% AFUE Two Stage Gas Furnace Multi-Position entries carry the same model and specifications, making their listed prices the key distinction.
- The ACiQ N80MSN1102120A Gas Furnace 110,000 BTU 80% AFUE Multi-Speed ECM Open Box is the distinct condition-based option, combining an open-box designation with a multi-speed ECM blower.

Decision matrix
- Prioritize the highest listed efficiency range and heating rating: Choose the 120,000 BTU ACiQ. It combines a 95-96% AFUE rating with a multi-speed high-efficiency blower and a 1-stage design.
- Want two-stage operation with a variable-speed blower: Focus on the Johnson Controls TM8V080C16MP12C. Both entries are new, rated at 80% AFUE, list 1,600 CFM airflow capacity, and support upflow or horizontal configuration.
- Make listed price the deciding factor for the Johnson Controls model: The USD 700.00 Johnson Controls entry is the lowest-priced option in the comparison while retaining the same named model and specification set as the USD 1,169.10 entry.
- Are specifically considering an open-box furnace: The ACiQ N80MSN1102120A is the relevant match, with single-stage, non-condensing operation and a multi 18-speed ECM blower described up to 2,040 CFM.
Product notes
120,000 BTU 96% Propane/Natural Gas Furnace Multi-Positional 1-Stage 9-Speed R32
Choose this ACiQ furnace when the stated 120,000-120,999 BTU heating rating and 95-96% AFUE range fit the requirements of the heating system. Its title identifies natural gas and propane use, while the specifications add a multi-speed high-efficiency blower and 2,000-2,999 CFM airflow volume. The multi-positional format is another reason it may suit a project with placement flexibility. The tradeoff is straightforward: at USD 2,432.00, it carries the highest listed price of the four. It is also a 1-stage furnace, rather than the two-stage setup named on the Johnson Controls model.
Johnson Controls TM8V080C16MP12C 80% AFUE Two Stage Gas Furnace Multi-Position - USD 1,169.10
This new Johnson Controls TM8V080C16MP12C is a clear choice when you want the combination of an 80% AFUE rating, two-stage gas operation, and a variable-speed blower motor. It lists an 80,000 BTU heating rating, 1,600 CFM airflow capacity, and upflow/horizontal configuration. The two-stage format is intended to operate at a lower level during milder conditions before moving to full capacity when needed. Its limitation in this comparison is price: the USD 1,169.10 entry is USD 469.10 above the other listing carrying the same Johnson Controls title, model, and stated specifications.
Johnson Controls TM8V080C16MP12C 80% AFUE Two Stage Gas Furnace Multi-Position - USD 700.00
Pick this Johnson Controls entry when the TM8V080C16MP12C's stated two-stage operation and variable-speed blower are the features you want, while keeping the listed price as low as possible in this group. It matches the other Johnson Controls entry on new condition, 80% AFUE, 80,000 BTU heating rating, 1,600 CFM airflow capacity, and upflow/horizontal configuration. That makes it the direct like-for-like price comparison in this set. The limitation is the same as for the other TM8V model: its 80% AFUE rating and 80,000 BTU heating rating are a different specification direction from the 95-96% AFUE, 120,000 BTU ACiQ option.
ACiQ N80MSN1102120A Gas Furnace 110,000 BTU 80% AFUE Multi-Speed ECM Open Box
The ACiQ N80MSN1102120A is aimed at shoppers who are comfortable selecting an open-box gas furnace and want a listed multi-speed ECM blower. It is described as a single-stage, non-condensing unit with 80% AFUE efficiency, Category I venting, and a maximum airflow figure of 2,040 CFM. The product description also identifies a constant-torque, multi 18-speed ECM motor. Its key limitation is condition: it is designated open box and described as scratch and dent, sold as-is. That makes condition a central part of the choice rather than a minor specification detail.
Final recommendation by use case
Choose the 120,000 BTU 96% Propane/Natural Gas Furnace Multi-Positional 1-Stage 9-Speed R32 when the priority is the higher listed AFUE range and heating rating. Choose the USD 700.00 Johnson Controls TM8V080C16MP12C for the same named two-stage, variable-speed model at the lowest listed price. The higher-priced Johnson Controls entry retains the same model specifications, so it is best considered only when that specific listed option is the one under consideration. Choose the ACiQ N80MSN1102120A when its open-box condition and multi-speed ECM setup align with your purchase criteria.
