// Bottom Line
This Goodman system makes sense for homeowners upgrading from older equipment who want solid efficiency gains without premium pricing. The 97% AFUE furnace and modulating burner deliver better comfort and lower heating bills, while the 5-ton, 16 SEER2 AC handles most mid-sized homes effectively.

Review

Goodman's 5-ton gas furnace and air conditioning combination targets the bread-and-butter residential replacement market where value matters more than premium features. With 97% AFUE heating efficiency, 16 SEER2 cooling performance, and ENERGY STAR certification, this system sits comfortably above builder-grade equipment while staying accessible to cost-conscious homeowners. The modulating furnace and variable-speed blower motor show Goodman's commitment to comfort and efficiency without exotic complexity.

The furnace delivers 100,000 BTU of heating output with modulating burner technology that ramps up or down rather than cycling on and off. The 5-ton air conditioner produces 54,000 BTU of cooling with a scroll compressor and R410A refrigerant compatibility. Maximum airflow reaches 2,000 CFM through the variable-speed ECM motor. The 73 dB noise level during operation is acceptable but noticeable in quiet rooms. Electrical requirements of 208/230V 1-phase 60 Hz and breaker sizing between 29.6 and 50 amps fall within standard home service capacity.

Pros & Cons

Pros

  • 97% AFUE furnace with modulating burner reduces energy waste and improves temperature consistency compared to single-stage alternatives
  • Variable speed ECM blower motor automatically adjusts to optimal airflow, lowering electricity consumption and noise
  • 16 SEER2 rating on 5-ton cooling unit qualifies for ENERGY STAR and most utility rebates
  • Scroll compressor and PVC flue compatibility simplify installation in retrofit applications
  • 10-year warranty with online registration provides solid peace of mind for mid-market buyers

Cons

  • 73 dB noise level runs louder than premium variable-capacity competitors, noticeable during heating cycle
  • Single-stage condenser cannot modulate cooling capacity, wasting energy on mild days unlike two-stage systems
  • Requires 208/230V single-phase power, limiting installation flexibility in some older homes without electrical upgrades

Who Should Buy

Best For

Homeowners in 1,500-2,500 square foot homes looking to replace 10-15 year old equipment will see genuine utility savings from the 97% AFUE rating and modulating furnace. Contractors value the straightforward installation, PVC flue compatibility, and attractive rebate eligibility.

Consider Alternatives If

Skip this if you need whisper-quiet operation, live in a very mild climate where single-stage cooling is wasteful, or lack 208/230V electrical service without planning upgrades.

Installation

This upflow configuration suits basement and mechanical room placement with right-side flue exit. PVC flue compatibility simplifies venting through exterior walls compared to metal ductwork requirements. The 30 inch by 21 inch by 21 inch footprint and 48-pound weight fit standard equipment spaces. Contractors should verify 208/230V availability and install 3/8 inch liquid and 1 1/8 inch suction lines with proper insulation per documentation.

Warranty & Reliability

Goodman covers parts and labor for 10 years when you register online after installation. This matches industry standard non-premium coverage and protects against manufacturing defects in the compressor, motor, and heat exchanger. However, shipping and service calls after year one typically fall to the homeowner, so factor that into long-term cost planning.

Frequently Asked Questions

How much will this system lower my heating bills versus a 90% AFUE furnace? +
The 97% AFUE rating versus 90% AFUE means roughly 7% better efficiency annually. On a 100,000 BTU furnace heating a typical home, expect $150-300 yearly savings depending on local gas prices and heating degree days. Modulating burner adds another 5-10% efficiency in mild weather when full capacity is unnecessary.
Can I install this in an attic or horizontal position? +
This upflow model is certified for upflow and downflow configurations. Horizontal attic installation requires different ductwork planning but the unit supports it. Check AHRI certificate 7424267 and contact Goodman technical support to confirm your specific horizontal layout before purchase.
Does the variable-speed blower really reduce electric bills? +
Yes. The ECM motor ramps down during mild weather and heating-only periods, using 50-70% less blower electricity than single-speed motors. On a year-round basis, expect $30-60 annual savings in most climates. This compounds the furnace efficiency gains for total utility improvement.
How does the 16 SEER2 rating compare to higher-efficiency units? +
16 SEER2 qualifies as high efficiency and earns ENERGY STAR status. Premium systems reach 18-20 SEER2 but cost significantly more. For moderate climates and typical usage, 16 SEER2 delivers most of the efficiency benefit at 70% of premium pricing, making it the sweet spot for value-focused buyers.
What happens after the 10-year warranty expires? +
Coverage ends after 10 years. Service calls and parts become your responsibility. Budget $200-500 annually for preventive maintenance and potential repairs after year 10 to extend system life toward year 15-17.
