Review
Goodman's combination gas furnace and air conditioner system represents a solid mid-to-premium offering for homeowners seeking all-in-one climate control. This upflow configuration fits standard indoor installations, and the modulating furnace with variable-speed blower provides responsive comfort management. The system integrates Goodman's proven scroll compressor technology with modern refrigerant compatibility, positioning it as a practical choice for replacement or new construction across residential markets.
Performance numbers tell the real story here. The furnace delivers 97% AFUE efficiency with 120,000 BTU heating output, meaning 97 cents of every dollar spent on fuel generates usable heat. Cooling capacity registers at 45,500 BTU with a 16 SEER2 rating, translating to measurably lower summer electric bills compared to baseline equipment. The variable-speed blower maxes out at 2,000 CFM, allowing the system to fine-tune airflow for both heating and cooling cycles rather than operating full-blast constantly.
Pros & Cons
Pros
- 97% AFUE furnace converts nearly all fuel to usable heat, minimizing waste and reducing winter heating bills
- 16 SEER2 air conditioner efficiency rating qualifies for Energy Star certification and many utility rebates
- Modulating burner stages adjust heating output in real time, improving comfort and reducing cycling
- Variable speed ECM blower motor runs efficiently at multiple speeds, matching system output to actual load
- 10-year warranty with online registration provides solid long-term protection against manufacturing defects
Cons
- Specification sheet lists contradictory tonnage (title says 4-ton, specs show 5-ton), creating confusion about actual cooling capacity
- 73 dBA noise level ranks slightly above industry average, which may be noticeable in quiet homes
- Single-stage cooling compressor cannot modulate capacity like two-stage units, potentially less efficient during partial-load conditions
Who Should Buy
Best For
Homeowners in mixed climates with significant heating and cooling demands who plan to stay in their home long enough to recover higher upfront costs through energy savings. This system suits those who value quiet operation less than maximum efficiency.
Consider Alternatives If
Buyers in primarily cooling climates, homes with noise sensitivity concerns, or those unable to clarify the actual tonnage specification before purchase.
Installation
Installation requires standard split-system procedures with proper lineset sizing and electrical connections. The system accepts R410A or R22 refrigerant depending on existing equipment. Technicians should verify the plastic or PVC exhaust flue configuration works with your home's venting layout. Electrical demands fall between 23.9 and 40 amps, requiring appropriate breaker sizing. Component weight of 48 pounds allows single-technician handling in most scenarios.
Warranty & Reliability
Ten-year manufacturer warranty against defects applies with online registration, protecting against compressor failure, heat exchanger cracks, and component malfunctions. This duration exceeds many budget alternatives but falls short of some premium brands offering 12-year coverage. Warranty terms require proper installation and maintenance to remain valid, typical across the industry.
