Review
Goodman's 5-ton upflow system represents a thoughtful middle-ground approach for regions where heating demand outpaces cooling needs. The 120,000 BTU furnace with 97% AFUE efficiency sits in the premium class for gas furnaces, while the 54,000 BTU air conditioner delivers respectable cooling without oversizing for mild summers. This SKU LS381183850 carries Energy Star certification and an AHRI certificate number 7424268, confirming lab-verified performance. Aimed at cost-conscious contractors and homeowners willing to prioritize winter comfort over summer cool-down speed, the system strikes a practical balance.
Performance data tells the story here. The furnace's modulating burner stages output between 40,000 and 120,000 BTU, eliminating the energy waste of traditional on-off cycling. The 16 SEER2 air conditioner uses a scroll compressor for smooth operation at 73 dBA, acceptable for most residential settings. Variable-speed ECM blower reaches 2,000 CFM maximum and adjusts continuously, consuming substantially less electricity than constant-speed alternatives. With R410A or R22 refrigerant compatibility, this unit offers installation flexibility, though R410A is the newer standard. The 10-year warranty with online registration provides reasonable long-term protection.
Pros & Cons
Pros
- 97% AFUE furnace efficiency means minimal gas waste, translating to lower winter heating bills in climates with moderate heating demand
- 16 SEER2 cooling efficiency beats the Energy Star minimum and qualifies for utility rebates in most regions
- Modulating burner adjusts output in real time, reducing on-off cycling and improving comfort consistency
- Variable-speed ECM blower motor ramps airflow intelligently, cutting auxiliary electricity consumption by 25-40% versus fixed-speed units
- Scroll compressor design runs quieter at 73 dBA and produces fewer vibrations than rotary competitors
Cons
- Single-stage condenser cannot modulate cooling output, so it short-cycles on mild days instead of running continuously at reduced capacity
- 54,000 BTU cooling capacity is borderline for 5 tons in hot climates, meaning longer run times in peak summer heat
- Plastic PVC flue requirement limits retrofit applications in older homes with masonry chimneys
Who Should Buy
Best For
Homeowners in northern and moderate climates who heat more than they cool, particularly those replacing aging furnaces with poor AFUE ratings. Contractors installing complete system replacements where heating dominates energy usage will see strong customer satisfaction.
Consider Alternatives If
Buyers in high-heat regions like Arizona and Texas should look at higher SEER2 units, and those with existing masonry chimney systems may face expensive flue modifications.
Installation
Upflow configuration suits basements and utility closets with overhead ductwork distribution. The 30 by 24.5 by 21 inch footprint fits standard mechanical spaces without extensive retrofitting. Electrical requirements are modest, 115V single-phase 60 Hz service with breaker sizing between 29.6 and 50 amps. PVC flue requirement allows horizontal and vertical venting through exterior walls or rooflines, simplifying many installations. Suction line insulation at 1/2 inch thickness and 50-foot maximum length are standard for R410A systems.
Warranty & Reliability
The 10-year parts and compressor warranty covers defects when registered online within 30 days of purchase. This exceeds typical 5-year baseline coverage, adding meaningful value. Evaporator coil coverage extends protection to matched indoor components. Registration is simple but mandatory, so skip this step and you forfeit extended protection. Coverage excludes labor, refrigerant, and damage from improper installation or maintenance.
