Review
Goodman's TX5N4 represents the practical middle ground in residential HVAC, delivering respectable efficiency without the complexity or cost of premium systems. As a 4-ton unit rated at 15 SEER (16 SEER1) and 96% AFUE, it competes directly against thousands of installations made annually by regional contractors. This horizontal configuration targets attic and basement installations where space constraints rule out larger equipment, making it particularly valuable for retrofit scenarios where ductwork already exists.
The numbers tell a straightforward story. The 120,000 BTU furnace at 96% AFUE converts nearly every dollar of fuel into usable heat, while the 48,000 BTU cooling capacity handles four-ton loads across two stages. That variable-speed ECM blower motor caps out at 2000 CFM and adjusts throughout the day instead of cycling on-off like older designs, reducing energy waste substantially. The scroll compressor and R410A refrigerant are industry standards, meaning repair technicians everywhere carry compatible parts.
Pros & Cons
Pros
- 96% AFUE furnace rating is well above minimum efficiency standards, reducing heating costs by 20-30% versus 80% AFUE units
- Two-stage burner and compressor automatically adjust output to match demand, improving comfort and reducing cycling losses
- Variable-speed ECM blower motor runs efficiently year-round, lowering electricity consumption compared to standard single-speed motors
- PVC exhaust venting eliminates expensive masonry flue requirements and simplifies installation in tight spaces
- ENERGY STAR certified system qualifies for utility rebates that can offset 10-15% of purchase price
- 10-year parts warranty with online registration provides genuine peace of mind for homeowners
Cons
- SEER1 rating of 16 lags behind modern 18+ SEER systems, meaning higher cooling costs in hot climates
- 74 dB noise level is noticeably louder than high-end variable-capacity competitors, potentially noticeable in quiet neighborhoods
- Horizontal configuration limits placement options, requiring basement or attic space; not suitable for ground-level closet installations
- Two-stage design cannot modulate capacity smoothly like inverter-driven systems, resulting in slightly less consistent temperature control
Who Should Buy
Best For
Homeowners in transitional climates with moderate heating and cooling needs, particularly those upgrading from 1990s equipment. Contractors serving budget-conscious customers who prioritize reliability and efficiency without premium pricing.
Consider Alternatives If
Buyers in hot climates needing minimal cooling costs should examine 18+ SEER options, and anyone in noise-sensitive areas should audition units before purchase.
Installation
This system requires 208-230V single-phase power with breaker capacity between 27.7 and 45 amps, standard for most homes. PVC exhaust venting simplifies installation compared to traditional metal flues, and sweat-type refrigerant valves use 3/8-inch liquid and 7/8-inch suction lines. Horizontal mounting demands adequate clearance above ductwork, and proper airflow return must be engineered during initial design.
Warranty & Reliability
The 10-year parts warranty applies automatically upon online registration, covering defects in manufacturing for a full decade. This is competitive with Goodman's peers and covers compressor, coil, and motor components. Labor and refrigerant are not included, so budget separately for technician time if repairs are needed after the first year.
