Choose the Right Type of Complete HVAC System
A complete central HVAC system can use gas heat, electric heat, or a heat pump. Your existing equipment, utility connections, comfort goals, and property requirements help determine the right configuration.
Electric Central HVAC Systems
An electric split HVAC system typically combines:
- Outdoor AC condenser
- Indoor air handler
- Electric heat kit
The air conditioner cools the property while the air handler distributes conditioned air through the ductwork. Electric heat provides heating when needed.
You can also shop individual air handlers and electric heat kits for compatible HVAC projects.
Heat Pump Systems
A heat pump provides heating and cooling. During summer, it removes heat from the building. During cooler weather, it reverses operation to provide heat.
A complete split heat pump system generally pairs an outdoor heat pump with an indoor air handler and compatible electric heat kit where required.
Compare complete heat pump packages above or browse individual heat pump condensers.
Central AC and Gas Furnace Systems
An AC and furnace combination pairs central air conditioning with gas heat.
A typical system includes:
- Outdoor AC condenser
- Gas furnace
- Evaporator or cased coil
This configuration is relevant for buyers looking for a furnace with air conditioning, central air and furnace combo, AC unit with furnace, or gas furnace and central air package.
Green Leaf Air also sells individual gas furnaces and cased coils.
Complete HVAC Systems from 1.5 to 5 Tons
Green Leaf Air offers complete Trane and Goodman HVAC systems in 1.5 to 5 ton capacities for residential and light commercial properties.
Available system sizes include:
- 1.5 ton: 18,000 BTU
- 2 ton: 24,000 BTU
- 2.5 ton: 30,000 BTU
- 3 ton: 36,000 BTU
- 3.5 ton: 42,000 BTU
- 4 ton: 48,000 BTU
- 5 ton: 60,000 BTU
The correct HVAC tonnage depends on more than square footage. Insulation, windows, sun exposure, ceiling height, air leakage, ductwork, occupancy, and local climate can all affect the cooling load.

Compare HVAC Systems by SEER2 Rating
SEER2 measures seasonal cooling efficiency for central air conditioners and heat pumps.
A higher SEER2 rating generally means greater cooling efficiency, but efficiency is only one part of the buying decision. Equipment cost, compressor technology, system sizing, installation quality, and expected ownership period also matter.
14.3 SEER2 Systems
14.3 SEER2 systems provide a practical option for buyers who want current-generation equipment with a lower initial investment.
15.2 SEER2 Systems
15.2 SEER2 equipment represents a large part of Green Leaf Air’s current complete HVAC selection.
Both Trane and Goodman offer options at this efficiency level, making it useful for buyers comparing brands, tonnage, and system configurations at a similar efficiency rating.
16 SEER2 Systems
Higher-efficiency Trane systems add two-stage and upgraded comfort options on selected models.
These systems can appeal to buyers who value longer operating cycles, more consistent temperatures, and improved comfort control.
18 SEER2 Variable-Speed Systems
Selected Trane 18 SEER2 systems use variable-speed or variable-capacity technology.
Instead of operating at one fixed output, the system can adjust performance based on changing demand. This can support more consistent indoor temperatures, quieter operation, and better humidity control.
What Is Included in a Complete HVAC System?
Green Leaf Air’s complete HVAC systems pair compatible indoor and outdoor equipment for central heating and cooling. The components depend on whether you choose an electric AC system, heat pump system, or gas furnace and AC system. Current packages are available from Trane and Goodman in 1.5 to 5 ton capacities.
Electric HVAC Systems
A complete electric HVAC system uses a central air conditioner for cooling and an air handler to circulate conditioned air through the ductwork.
Goodman electric systems in this category pair an R-32 AC condenser with a compatible multi-position air handler. Current Goodman systems are available in 15.2 SEER2 configurations across multiple tonnages.
Trane electric systems pair the outdoor AC unit with a compatible air handler and electric heater. Green Leaf Air carries Trane electric systems from 14.3 SEER2 through premium two-stage and variable-speed configurations. Many current Trane systems use R-454B refrigerant, while refrigerant and equipment specifications vary by model.
Heat Pump HVAC Systems
A complete heat pump system provides both central cooling and heating without using a gas furnace.
Goodman heat pump systems pair an R-32 outdoor heat pump with a compatible multi-position air handler. Green Leaf Air currently carries Goodman 15.2 SEER2 heat pump systems from 1.5 through 5 tons.
Trane heat pump systems pair the outdoor heat pump with a compatible air handler and electric heater or heat kit. Depending on the model, buyers can choose single-stage, two-stage, or variable-speed equipment. Selected higher-efficiency systems use TEM6 air handlers with appropriately sized electric heaters.
AC and Gas Furnace Systems
A complete gas HVAC system combines central air conditioning with a gas furnace for heating.
Green Leaf Air’s current Trane and Goodman gas systems pair an outdoor AC condenser with an 80% AFUE gas furnace and compatible indoor coil. Furnace capacity changes with the system configuration and tonnage.
Current Goodman gas packages use R-32 equipment with upflow/downflow coils. Trane gas systems include configurations with multi-positional coils, R-454B equipment, and single-stage, two-stage, or variable-speed options depending on the efficiency tier and model.
These are the systems to compare if you are shopping for a furnace with air conditioning, central air and furnace combo, AC unit with furnace, or complete gas heating and cooling system.
Check the Exact Equipment Before You Buy
Each product listing identifies the actual equipment included in that system, including tonnage, BTU capacity, SEER2 rating, furnace capacity, air handler size, coil configuration, electric heater size, refrigerant type, and system performance level where applicable. This makes it easier to compare complete systems based on real equipment specifications instead of brand or price alone.
If you need to replace an individual component rather than the complete system, shop central AC condensers, heat pumps, gas furnaces, air handlers, cased coils, or electric heat kits.

Complete HVAC System FAQs
What is included in a complete central HVAC system?
It depends on the system type. An electric system commonly includes an AC condenser, air handler, and electric heat kit. A heat pump system pairs a heat pump with an air handler. A gas HVAC system generally includes an AC condenser, gas furnace, and evaporator coil. Check our each product listing for exact included equipment.
What size HVAC system do I need?
The correct size depends on the building’s heating and cooling load. Square footage alone is not enough. Insulation, windows, air leakage, ductwork, ceiling height, orientation, occupancy, and local climate also affect sizing. Contact us for expert help.
What is the difference between a 2.5 ton and 3 ton AC system?
A 2.5 ton system provides about 30,000 BTU of nominal cooling capacity. A 3 ton system provides about 36,000 BTU. The larger system is not automatically better. The correct choice depends on the property’s actual cooling load.
What does SEER2 mean?
SEER2 is a seasonal efficiency rating for central air conditioners and heat pumps. Higher SEER2 ratings generally indicate higher cooling efficiency under the applicable testing procedure.
Is Trane or Goodman better?
Both brands serve different buyer priorities. Goodman is often attractive to value-focused buyers. Trane offers a wider selection of higher-efficiency, two-stage, and variable-speed equipment. Compare equivalent systems by specifications, features, warranty, and price.
Do the HVAC systems come with a warranty?
Qualifying Trane and Goodman systems include a 10-year parts warranty, subject to applicable warranty and registration requirements.
