Product Information
Who This Furnace Is For
The Trane 80 Two-Stage Gas Furnace is a practical 80% furnace for homeowners who want a little more comfort than a basic single-stage model. This product was formerly known as the Trane S8X2.
The main upgrade is the two-stage gas valve. Instead of only firing at full heat, the furnace can run in a lower stage when the home does not need maximum output.
This can be a smart choice when you want an 80% furnace, want to keep the price reasonable, and still want better temperature control than the most basic furnace.
Key Features
- Energy Efficiency: 80% AFUE
- Heating Stages: Two
- Blower Speed: Constant Torque
- Nine tap blower motor
- Two-stage gas heat
- Microelectronic controller
- Tubular steel heat exchanger
- Insulated cabinet for quiet operation
Benefits
- Two-stage heating for better comfort than a basic 80% furnace
- Lower installed cost than variable-speed furnace options
- Simple, reliable furnace platform
- Good fit when 80% venting makes sense for the home
- More affordable than the 80 Two-Stage Variable Speed Gas Furnace
Considerations
- Lower efficiency than 90%+ condensing furnaces
- No variable-speed blower
- Less airflow control than the S8V2-C replacement
- Not the best fit if comfort complaints are mostly airflow-related
What Our Service Department Says
This is a good furnace to compare when the homeowner wants a durable 80% furnace but does not want the most basic option. The two-stage heat is the main reason to step up.
If the budget allows and airflow is a concern, we would also talk through the 80 Two-Stage Variable Speed Gas Furnace.
