Review
The Goodman 3-ton split system sits squarely in the middle market, combining proven two-stage technology with accessible pricing at $2,641. This upflow A-coil configuration handles both air conditioning and gas heating, delivering 35,000 BTU cooling and 60,000 BTU heating from a footprint measuring 34.5 inches tall and 17.5 inches wide. The system targets residential applications where space is tight and budget constraints favor reliability over cutting-edge efficiency.
Performance metrics show real-world viability. The condenser achieves 18 SEER2 cooling efficiency using R410A refrigerant and a scroll compressor, while the furnace delivers 80% AFUE with two-stage burners and variable-speed blower. At maximum capacity, the unit moves 1,600 CFM, adequate for homes up to 2,000 square feet. The two-stage design means the system ramps output gradually, reducing on-off cycling and delivering steadier indoor temperatures than single-stage competitors.
Pros & Cons
Pros
- 18 SEER2 cooling efficiency exceeds the 15 SEER minimum, reducing summer electricity costs by roughly 20 percent compared to baseline units
- Two-stage furnace with variable-speed blower optimizes comfort during partial-load operation, minimizing temperature swings
- Energy Star certified, qualifying buyers for rebates in most utility territories
- Scroll compressor is field-proven and inexpensive to service compared to rotary designs
- Compact A-coil footprint (17.5 inches wide) fits tight attic and basement installations
- 10-year warranty with online registration covers parts and compressor
Cons
- 80% AFUE furnace is adequate but not high-efficiency, missing out on 90+ percent models that save 500-800 dollars annually in gas costs
- 71 dB noise level at condenser is above-average for residential units, noticeable during evening operation
- Metal exhaust flue requirement limits installation flexibility in some retrofit applications
Who Should Buy
Best For
Homeowners replacing a failed system in a three-ton load area who want better-than-average efficiency without jumping to premium tiers. Contractors stocking reliable mid-market equipment for residential service calls will appreciate the straightforward two-stage design and competitive $2,641 price point.
Consider Alternatives If
Buyers in very cold climates should consider higher AFUE options, and those prioritizing quiet operation should audition lower-decibel alternatives before committing.
Installation
This upflow system requires standard two-inch and three-quarter-inch lineset connections with sweat valve terminations. Minimum breaker size is 21.3 amps and maximum is 35 amps at 120 volts, 1 phase, 60 Hz. Metal exhaust flue is mandatory for the furnace. Installation complexity is moderate, suited to experienced HVAC technicians familiar with Goodman equipment. The 50-foot suction line insulation reduces field customization.
Warranty & Reliability
Goodman backs this unit with a 10-year parts warranty when you register online within 30 days of installation. The compressor carries the same 10-year coverage. This is mid-tier protection that covers defects but excludes wear items and labor, typical for this price range. Registration is straightforward and extends coverage beyond the base five-year limited warranty.
