Review
The Goodman 3 Ton 13 SEER gas furnace and air conditioner system occupies the practical middle ground that most contractors actually sell. At $3,770, it's not a premium package, but it's also not a bare-bones budget unit. This downflow configuration suits basements and crawlspaces across residential builds, and the ACiQ branding indicates Goodman's reliable engineering. The system handles 120,000 BTU heating and 36,000 BTU cooling, making it suitable for medium-sized homes across mixed climates.
Where this system earns its rating is in actual performance numbers. The furnace's 96% AFUE rating means you're losing almost nothing to exhaust, while competitors at this price often sit at 92 to 94 percent. The 13 SEER air conditioner carries ENERGY STAR certification, and the variable-speed ECM blower motor adjusts output to your home's real demand rather than cycling on and off like older fixed-speed designs. A two-stage burner prevents temperature swings by modulating heat output. Real homeowners upgrading from 1990s-era furnaces typically see 20 to 30 percent annual heating cost reductions.
Pros & Cons
Pros
- 96% AFUE furnace efficiency means minimal heat loss during winter operation, translating to lower gas bills
- 13 SEER air conditioner is ENERGY STAR certified and outperforms many budget alternatives by 2-3 SEER points
- Variable-speed ECM blower motor runs quieter and more efficiently than fixed-speed motors, improving comfort and reducing electricity draw
- Two-stage burner adjusts heating output to match demand, preventing on-off cycling and temperature swings
- 10-year warranty with online registration provides meaningful protection at this price point
- Accepts both natural gas and propane, offering flexibility for different regional fuel availability
Cons
- Single-stage compressor on the AC side limits efficiency gains compared to two-stage or modulating units in very hot climates
- 74 dB noise level is noticeably loud during cooling operation, particularly noticeable in quiet neighborhoods
- Reciprocating compressor design generates more vibration than scroll compressors, requiring careful ductwork support
Who Should Buy
Best For
Contractors serving residential markets in Midwest and Mid-Atlantic regions will appreciate this system's reliability and middle-ground pricing. Homeowners replacing 10-to-15-year-old equipment with tight budgets but realistic efficiency expectations are ideal candidates.
Consider Alternatives If
Skip this if you live in extreme heat climates where two-stage cooling is common, or if you prioritize whisper-quiet operation in noise-sensitive settings.
Installation
This downflow unit requires 115V single-phase 60 Hz power with a breaker between 19.1 and 30 amps, standard for most homes. The system accepts plastic PVC exhaust flue, which simplifies venting compared to metal ductwork. Standard sweat valve connections use 3/8-inch liquid lines and 3/4-inch suction lines. Total weight of 120 pounds is manageable for two technicians. Most installations take a full day for experienced crews familiar with Goodman equipment.
Warranty & Reliability
Ten years parts coverage with free online registration is competitive for this price tier. Goodman honors it well, and the AHRI certificate number 7368845 confirms system matching. Note that labor is not covered, only parts. Registering immediately after installation ensures coverage activation, and you'll want to document the purchase receipt.
