80% AFUE Metal Vented Furnace

These gas furnace and AC split system combos are a smart fit for replacing existing 80% AFUE upflow/horizontal units in homes, rentals, and light commercial spaces. Built for dependable heating and cooling, they pair a metal-vented furnace with a matched outdoor condenser using R-32 refrigerant. Contractors, DIY-capable homeowners, and property managers will find sizes to serve small rooms to large zones, with package pricing typically from $2945 to $6045.

Match capacity to your project: cooling from 1.5-5 tons and heating inputs from 40,000-120,000 BTU. Choose SEER2 ratings of 14, 14.5, or 15.2 based on regional requirements and budget. These AFUE 80, operating-mode gas, split systems are designed for upflow/horizontal airflow and offered in cabinet widths of 14 in, 17.5 in, 21 in, and 24.5 in to simplify plenum transitions. R-32 refrigerant delivers efficient performance when properly charged and commissioned.

Professional installation is required. A licensed HVAC pro must size equipment, connect and test gas lines, set metal/B-vent flue, verify combustion air and clearances, and handle R-32 refrigerant per code. Correct coil matching, airflow setup, and thermostat configuration ensure comfort, efficiency, and warranty compliance.

We stock popular tonnages and BTU inputs for quick turnarounds, making it easy to standardize across multiple properties or light commercial upflow jobs while maintaining code-compliant metal venting and proven reliability.

Frequently Asked Questions

  • What size (tonnage or BTU) 80% AFUE gas furnace and AC combo do I need for my home?

    Have a Manual J load calculation performed. Typical ranges are 1.5-5 tons for cooling and 40k-120k BTU for heating, depending on climate and home specifics.

  • Are these Goodman 80% AFUE systems compatible with existing upflow/horizontal ductwork and gas lines?

    Yes, they are designed for upflow/horizontal applications. A licensed installer must verify duct sizing, gas pipe capacity, and proper metal/B-vent flue.

  • What SEER2 options (14, 14.5, 15.2) are available with these R-32 split systems?

    Systems are offered in SEER2 14, 14.5, and 15.2. The final rating depends on the matched condenser and coil combination selected.

  • Can I pair these furnaces with my existing thermostat and indoor coil?

    Most conventional thermostats work. Coils must be properly matched and compatible with R-32; many replacements include a new coil to ensure AHRI match.

  • What cabinet widths are offered and how do they fit existing return plenums?

    Cabinets come in 14, 17.5, 21, and 24.5 inches. Measure your plenum; a simple transition may be required for a snug, efficient fit.

  • Is professional installation required for gas line, venting, and refrigerant (R-32) handling?

    Yes. Codes mandate licensed installation, proper metal venting, pressure testing, and EPA 608-certified handling of R-32 refrigerant.

  • How do I choose between BTU inputs (40k-120k) and tonnage (1.5-5 ton)?

    BTU input addresses heating load; tonnage addresses cooling and dehumidification. Correct sizing requires a Manual J and duct evaluation.

  • Are these systems suitable for light commercial spaces with upflow installations?

    Yes, for offices, retail, and similar spaces. Verify ventilation, gas capacity, clearances, and local code requirements before selection.

  • Do these furnaces require metal venting or can they use PVC?

    80% AFUE furnaces use metal/B-vent flue systems. PVC venting is for high-efficiency condensing models, not 80% units.

  • What is the typical price range and what is included?

    Most combos run about $2945-$6045 and include the furnace, matched indoor coil, and outdoor condenser. Accessories and installation are additional.
