Review
The Goodman 5-ton system reviewed here represents a solid mid-tier choice for residential HVAC replacement. Positioned between budget units and premium variable-capacity systems, this combination furnace and air conditioner handles demanding cooling loads while maintaining steady heating through modulating gas burners. Goodman's reputation for straightforward engineering and parts availability gives contractors confidence in long-term serviceability. At this capacity and efficiency tier, it competes directly with Lennox XC16 and Carrier 25HNH36 units.
Performance specs reveal a well-balanced design emphasizing practical efficiency over cutting-edge features. The 16 SEER2 cooling rating, backed by AHRI Certificate 7424266, delivers 34,800 BTU of effective cooling from the scroll compressor operating at single-stage capacity. The furnace generates 80,000 BTU heating with 97% AFUE, using a modulating burner to reduce temperature swings. Variable-speed ECM blower with maximum 1,600 CFM output adjusts airflow based on load, minimizing unnecessary energy consumption. The 115V single-phase 60Hz electrical requirement fits standard residential service.
Pros & Cons
Pros
- 16 SEER2 cooling efficiency exceeds the 15 SEER rating advertised, with Energy Star certification
- 97% AFUE furnace with modulating burner stages adjusts heating output for steady temperatures
- Variable-speed ECM blower motor reduces runtime and energy waste compared to single-speed units
- Scroll compressor with single-stage cooling provides reliable, proven performance across residential applications
- PVC exhaust flue compatible with modern venting systems, simplifying retrofits and new installations
Cons
- Single-stage compressor cannot modulate cooling capacity, leading to higher short-cycling in mild weather
- 73.5 dB noise level is moderately loud and may be noticeable in quiet neighborhoods
- 5-ton capacity oversizes many residential applications, reducing efficiency in homes under 3,000 square feet
Who Should Buy
Best For
Contractors and homeowners installing systems in homes between 2,500 and 4,000 square feet in humid or warm climates will benefit from the higher cooling capacity and strong heating backup. This system suits mixed-use homes where both seasonal demands matter equally.
Consider Alternatives If
Skip this if you need a smaller capacity for efficient operation in mild climates, or if budget-conscious operation during shoulder seasons is a priority, since the single-stage compressor will short-cycle frequently.
Installation
Installation follows straightforward A-coil upflow configuration compatible with basements, attics, or utility closets. Standard 3/8-inch liquid line and 7/8-inch suction line with 3/4-inch insulation thickness keep setup consistent with typical ductwork. PVC exhaust flue requirement simplifies venting compared to metal alternatives. Most licensed HVAC contractors complete installation in one to two days. Electrical needs require 18.7 to 30 amp breaker sizing, manageable for homes with adequate service capacity.
Warranty & Reliability
Goodman includes 10-year coverage when you register online after purchase, protecting against manufacturer defects in compressor, heat exchanger, and major components. This mid-tier warranty matches most competitor offerings at this price point. Parts availability through Online Supply and authorized distributors reduces downtime if service becomes necessary. Registration is required to activate coverage, so save documentation.
