Review
Goodman's 3-ton upflow gas furnace and air conditioner system sits squarely in the value-conscious segment, delivering real efficiency improvements without the premium pricing of top-tier brands. At 3,398 dollars, this SKU TX3N4 configuration offers contractors and homeowners a certified, rebate-eligible package that doesn't compromise on essential features. The combination of 96% AFUE heating with 16 SEER cooling covers most residential applications effectively.
The furnace produces 80,000 BTU of heating output with two-stage burners that modulate to match home demand, while the 3-ton air conditioner delivers 35,000 BTU at 16 SEER using a two-stage scroll compressor and R410A refrigerant. The variable-speed ECM blower motor reaches 1,200 CFM maximum and adjusts automatically, reducing runtime noise and energy waste during partial-load operation. Energy Star certification confirms these efficiency claims hold up in real-world testing conditions.
Pros & Cons
Pros
- 96% AFUE furnace efficiency with two-stage burners cuts heating costs measurably compared to 80% units
- 16 SEER rating with two-stage condenser and scroll compressor provides genuine cooling efficiency for the price point
- Variable-speed ECM blower motor runs quieter and adjusts to actual demand, improving comfort
- PVC exhaust compatibility simplifies venting in tight retrofit situations
- Energy Star certified with rebate eligibility in most utility territories
- Compact dimensions (30 inches tall, 17.5 inches wide) fit standard utility closets and tight spaces
Cons
- 71 dB noise level is audible during operation, noticeable in quiet homes or basements
- R410A refrigerant is older and less efficient than modern alternatives like R32
- Two-stage design means efficiency gains only occur at part load, full load performs like single-stage
Who Should Buy
Best For
Homeowners in moderate climates seeking a practical efficiency upgrade without premium pricing, and HVAC contractors stocking a reliable 3-ton option for residential replacements. This system works well for properties with stable heating and cooling demand.
Consider Alternatives If
Buyers in extremely cold climates needing maximum heating output, or those prioritizing whisper-quiet operation should explore higher SEER units with scroll compressors rated below 70 dB.
Installation
This upflow configuration suits most standard furnace closets with its 30-inch height and 21-inch depth. The PVC exhaust requirement simplifies venting compared to metal ductwork, eliminating clearance headaches in retrofit projects. Requires 208/230V single-phase 60 Hz power with breaker capacity between 21.9 and 35 amps. Sweat valve connections (3/8-inch liquid, 7/8-inch suction) demand experienced HVAC technicians.
Warranty & Reliability
Goodman backs this system with 10 years parts coverage when registered online, a solid baseline for equipment at this price. Registration is essential, as warranty defaults to shorter periods without it. Parts availability through Goodman's distribution network is generally strong, supporting real-world repair scenarios.
