Choosing a furnace for your home's heating system starts with matching heat output to your space. These two Johnson Controls gas furnaces both offer 80,000 BTU of two-stage heat, but their listed prices and spec sheets pull them in different directions. The TM8V080B12MP12C is listed at $899.99, and the TM8V080C16MP12C is listed at $1,169.10. The higher-priced model adds several listed performance details, so the choice comes down to whether those details matter for your setup.
Quick Verdict
If you want a straightforward 80,000 BTU two-stage gas furnace with an ECM blower and fewer listed extras, start with the TM8V080B12MP12C. If you want a version with listed specs for 1600 CFM airflow, a variable-speed blower, Energy Star compliance, and upflow/horizontal configuration, the TM8V080C16MP12C is the one to choose.

Where Each Product Wins
The TM8V080B12MP12C wins on the price spread and the listed efficiency range. It is a new, 80,000-89,999 BTU gas furnace with an ECM two-stage blower and a US country of origin. Its AFUE range is listed as 80-85%, which is broader than the other model's flat 80% AFUE.
The TM8V080C16MP12C wins on airflow and configuration detail. It is listed with a 1600 CFM airflow capacity, a variable-speed blower motor, Energy Star compliance, and an upflow/horizontal setup. If your ductwork needs a higher airflow rating or you want a multi-position furnace, this model's specs give you more to work with.
Product Notes
Johnson Controls TM8V080B12MP12C 3 Ton 80000 BTU 80% Ecm Two-Stage Gas Furnace
This furnace keeps the selection simple. The listed AFUE range of 80-85% is wider than the flat 80% AFUE on the other model, and the US country of origin, new condition, and ECM blower are all stated. As a 3-ton, 80,000 BTU two-stage gas furnace, it is positioned as a straightforward heating unit. Keep in mind that the efficiency spec is a range, not a single number, so your actual efficiency will depend on how the furnace is matched to your system. For shoppers who want the core two-stage gas furnace spec without additional airflow extras, this model is the more restrained choice.
Johnson Controls TM8V080C16MP12C 80% AFUE Two Stage Gas Furnace Multi-Position
This model brings more to the table. The 1600 CFM airflow capacity, variable-speed blower motor, Energy Star compliance, and upflow/horizontal configuration are all part of the specs, and the unit is described as using an energy-efficient ECM blower for quiet operation. It still delivers 80,000 BTU of two-stage gas heat with an 80% AFUE rating. The limitation is the efficiency ceiling: the AFUE is shown as a flat 80%, which sits below the 80-85% range listed for the other model. If airflow and blower performance are your deciding factors, this is the product to focus on.
Final Choice by Use Case
For a straightforward 80,000 BTU replacement, the TM8V080B12MP12C gives you the core two-stage gas furnace features in a new, US-origin unit. For a system that needs the listed 1600 CFM airflow and variable-speed blower, the TM8V080C16MP12C is the more complete package. Use the airflow spec as your tiebreaker: if you need the extra airflow and blower control, the higher-priced model is the fit. If you are happy with the simpler spec, the other model covers the basics.
