Review
Goodman's two-stage system pairs an 80,000 BTU furnace with a 24,000 BTU air conditioner in a single matched unit designed for upflow installation. This is the type of offering that fills the middle ground in HVAC, targeting contractors and homeowners who want above-average efficiency without venturing into premium brand territory. The upflow A-coil configuration and sweat valve connections are standard for most residential replacements. Energy Star certification signals that this unit meets EPA efficiency thresholds, which often unlocks utility rebates.
The furnace delivers 97% AFUE efficiency through modulating burner stages that fine-tune heat output rather than cycling between full-on and off positions. On the cooling side, 16 SEER performance comes from a two-stage scroll compressor running at 71 dBA, paired with a variable-speed ECM blower capable of 1,200 CFM maximum. The modulating approach reduces temperature swings and extends equipment life by avoiding repeated hard starts. Real-world heating and cooling bills should run 10 to 15 percent lower than single-stage units, though results depend on installation quality and ductwork design.
Pros & Cons
Pros
- 97% AFUE furnace efficiency means minimal heating fuel waste, translating to measurable savings on winter gas bills
- 16 SEER cooling efficiency qualifies for Energy Star certification and many utility rebates
- Modulating burner stages heat output to actual demand, avoiding on-off cycling and temperature swings
- Variable-speed ECM blower motor adapts airflow for even distribution and lower electricity consumption
- Two-stage scroll compressor runs quieter at 71 dBA than single-stage units during partial load operation
Cons
- Tonnage mismatch in specs, 2 ton listed in title but 3 ton in condenser specifications, creates confusion for proper installation
- Requires licensed technician installation in many jurisdictions, adding $1,500 to $3,000 to total project cost
- 71 dBA noise level is moderately loud and may be noticeable from adjacent rooms during cooling cycles
Who Should Buy
Best For
Homeowners replacing aging furnace and AC units who want matched-pair efficiency and can use available rebates. Contractors serving moderate climate zones where 97% AFUE and 16 SEER balance operating costs with equipment affordability.
Consider Alternatives If
Budget-conscious buyers should compare single-stage alternatives, and those in extreme climates may benefit from higher SEER units.
Installation
This gas furnace requires a licensed technician in most jurisdictions, and that professional must verify proper gas line connections and PVC flue venting before startup. The unit needs 115V single-phase 60Hz power with a 15.7 to 20 amp breaker, which existing homes usually accommodate. The A-coil fits tight spaces at 34.5 inches tall and 17.5 inches wide, but confirm clearances in your return plenum before purchase. Improper installation voids warranty and creates safety hazards, so never attempt DIY installation.
Warranty & Reliability
Goodman provides 10 years of parts coverage when you register online within 30 days of installation. This is standard in the industry and protects against compressor failure, heat exchanger cracks, and component defects. It does not cover labor, refrigerant recharge, or damage from poor maintenance. Registration is straightforward and takes five minutes through Goodman's website.
