Review
Goodman's 3-ton gas furnace and air conditioner system represents solid mid-range equipment for contractors stocking common sizes. Priced at $89, this upflow configuration uses a scroll compressor with two-stage condenser support and modulating burner technology. The unit measures 30 inches tall by 21 by 21 inches, fitting standard equipment closets and basement installations. Energy Star certification signals compliance with current efficiency standards, important for homeowners claiming tax credits.
Performance metrics tell the real story here. The furnace delivers 80,000 BTU input with 97% AFUE, meaning 97 cents of every dollar spent on gas converts to usable heat, minimal waste up the flue. On cooling, the system produces 35,000 BTU at 16 SEER (or 18 SEER1 by newer standards), running on R410A refrigerant. The variable-speed ECM blower tops out at 1200 CFM while modulating down during milder weather. This staged approach cuts runtime, reducing noise from 71 dBA and extending compressor life.
Pros & Cons
Pros
- 97% AFUE with modulating burners reduces gas waste compared to single-stage alternatives, saving 10-15% on heating bills
- Variable-speed ECM blower motor runs quieter at partial load and improves humidity control, dropping decibel levels to 71 dBA
- Two-stage condenser supports 16 SEER cooling efficiency with R410A refrigerant, meeting modern standards without retrofit
- Plastic PVC exhaust flue allows installation in tight spaces where metal venting isn't feasible
- 10-year parts warranty with online registration covers manufacturing defects, standard for this equipment class
Cons
- 5-ton capacity listed in specs conflicts with 3-ton marketing claim, creating confusion about actual cooling output
- 71 dBA operating noise is moderate-to-loud during heating cycles, noticeable in open-concept homes
- Requires 208/230V single-phase power, limiting options in older homes with only 120V circuits
Who Should Buy
Best For
This system fits contractors building in cold climates where heating efficiency drives ROI and homeowners willing to prioritize operational savings over lowest upfront cost. It's ideal for existing homes already wired for 208/230V service.
Consider Alternatives If
Skip this if you need cooling as your primary load (sunbelt climates), live in a home with only 120V service, or require whisper-quiet operation in quiet neighborhoods.
Installation
Installation requires 208/230V single-phase 60 Hz power, minimum 21.3 amp breaker and maximum 35 amp sizing. Plastic PVC exhaust flue simplifies venting compared to metal alternatives, critical for tight crawlspaces. Sweat-type valve connections use 3/8-inch liquid and 7/8-inch suction lines with 3/4-inch insulation thickness. Most HVAC contractors complete installation in 4 to 6 hours on replacement jobs.
Warranty & Reliability
Goodman backs this unit with 10 years parts coverage upon online registration, standard industry practice for residential equipment. Labor costs fall on the contractor or homeowner. This warranty applies to manufacturing defects, not installation errors or refrigerant leaks from undersized linesets. Online registration typically takes five minutes and activates coverage immediately.
