What’s Included With Your Trane 14.3 SEER2 Gas System?
You are buying a complete central AC and gas furnace system, not an outdoor condenser by itself. Each configuration includes the equipment required for matched cooling and gas heating.
- Trane 14.3 SEER2 single-stage air conditioner: Provides the cooling side of the split HVAC system.
- 80% AFUE Trane gas furnace: Provides gas heating with furnace capacities from 40,000 to 100,000 BTU, depending on the selected system.
- Matched indoor coil: The indoor evaporator coil works with the outdoor AC equipment and furnace airflow.
- R-454B refrigerant equipment: The systems listed in this category use R-454B.
- Professional installation: Our HVAC team installs, starts, and tests the system as part of the listed price.
- 10-year parts warranty: We include a 10-year parts warranty with your new system.
The rated performance of a central HVAC system depends on the complete equipment combination. The condenser, furnace or blower, and indoor coil must work as a matched system. We verify the correct equipment configuration for the system you purchase.
Why Buy a Trane 14.3 SEER2 Gas System?
A Trane 14.3 SEER2 gas system makes sense when you want a complete Trane AC and furnace replacement without moving into the higher price range of two-stage or variable-speed equipment.
The 14.3 SEER2 category gives you:
- Lower upfront cost within our Trane gas lineup
- Single-stage central air conditioning
- 80% AFUE gas heating
- 1.5 to 5 ton cooling options
- 40,000 to 100,000 BTU furnace options
- R-454B equipment
- Free professional installation
- 10-year parts warranty
- Upfront package pricing with no hidden installation charge
This efficiency tier can be a practical choice for replacing an older AC and gas furnace when purchase price matters. If you place more value on higher cooling efficiency, two-stage operation, quieter low-stage performance, or more consistent temperature control, compare our higher-SEER2 Trane options before ordering.
Trane 14.3 vs 16 SEER2 Gas Systems: Which Should You Buy?
The main difference between 14.3 and 16 SEER2 is not simply the efficiency number. Green Leaf Air’s current 14.3 SEER2 gas systems use single-stage cooling, while our 16 SEER2 Trane gas systems move into two-stage equipment.
| Feature | Trane 14.3 SEER2 Gas System | Trane 16 SEER2 Gas System |
| Cooling Efficiency | 14.3 SEER2 | Higher |
| Cooling Operation | Single-stage | Two-stage |
| Upfront Cost | Lower | Higher |
| Temperature Control | Standard single-stage operation | More flexible two-stage operation |
| Part-Load Operation | Runs at full cooling output when on | Can operate at a lower stage when full output is not required |
| Best Fit | Buyers focused on Trane quality and lower upfront cost | Buyers willing to spend more for efficiency and two-stage comfort |
A higher SEER2 rating can reduce cooling energy use, but the value of the upgrade depends on your runtime, electricity cost, property, comfort priorities, and how long you expect to own the system.

Choose the Right Trane 14.3 SEER2 Gas System Size
Choosing the correct HVAC size matters as much as choosing the brand or SEER2 rating.
AC tonnage measures cooling capacity. Furnace BTU measures heating capacity. They solve different load requirements, so you should not choose a gas HVAC system from square footage alone.
Our current configurations include:
- 1.5 Ton: 40,000 BTU furnace
- 2 Ton: 40,000 BTU furnace
- 2.5 Ton: 60,000 BTU furnace
- 3 Ton: 80,000 BTU furnace
- 3.5 Ton: 80,000 BTU furnace
- 4 Ton: 100,000 BTU furnace
- 5 Ton: 100,000 BTU furnace
We consider the property’s cooling and heating load, insulation, windows, layout, ceiling height, existing ductwork, airflow, and other conditions before recommending a size. A properly sized system helps reduce short cycling, poor airflow, uneven temperatures, and excess indoor humidity.
If you are replacing an existing system, do not assume the old tonnage is automatically the correct size for the new equipment. Contact us if you need help choosing the right Trane AC and furnace configuration before ordering.

Buy Trane 14.3 SEER2 Gas Systems in Texas & North Carolina
Green Leaf Air sells and installs these Trane gas HVAC systems for residential and commercial properties in Texas and North Carolina. We do not sell these systems outside those two states.
Texas buyers often place more weight on long cooling seasons, correct AC sizing, airflow, and summer operating costs. North Carolina buyers also need to consider cooling, humidity, and winter heating capacity. In both states, correct equipment sizing matters more than selecting a system from square footage alone.

Trane 14.3 SEER2 Gas System FAQs
How much does a Trane 14.3 SEER2 gas system cost?
Our current Trane 14.3 SEER2 gas systems cost $8,199 to $8,399 with free professional installation. The 1.5, 2, and 2.5 ton systems are $8,199. The 3, 3.5, 4, and 5 ton systems are $8,399.
Is installation included in the Trane HVAC system price?
Yes. Professional installation is included in the price displayed on the product grid. We do not add a separate installation charge to the listed package price.
What does 14.3 SEER2 mean?
SEER2 measures seasonal cooling efficiency. A higher SEER2 rating indicates greater cooling efficiency under the test procedure used for the rating. SEER2 applies to the cooling side of the system, and AFUE measures gas furnace efficiency.
What does 80% AFUE mean on a Trane gas furnace?
AFUE stands for Annual Fuel Utilization Efficiency. An 80% AFUE furnace converts about 80% of the fuel’s annual energy into usable heat. AFUE describes furnace heating efficiency. It does not describe the AC system’s cooling efficiency.
What size Trane gas HVAC system do I need?
The correct size depends on the property’s cooling load, heating load, insulation, windows, layout, ductwork, airflow, and local climate. Do not choose tonnage from square footage alone. We can help you determine the appropriate system before purchase.
What is R-454B refrigerant?
R-454B is the refrigerant used by the Trane 14.3 SEER2 gas systems listed in this category. The outdoor AC equipment and matched indoor coil must be compatible with the refrigerant used by the system.
I am replacing an older Trane XR14. Can I shop this category?
Yes. If you are replacing an older Trane XR14 or comparing an XR14 replacement quote, our current 14.3 SEER2 gas systems are a useful starting point. We still confirm the current model, tonnage, furnace capacity, indoor coil, and installation requirements before you order.
Can I finance a Trane 14.3 SEER2 HVAC system?
Yes. Green Leaf Air offers flexible financing options for qualified customers. Contact us to review available payment options before purchasing your system.
