// Bottom Line
This Goodman system works best for homeowners in mild to moderate climates who want reliable cooling without premium pricing. The 18 SEER2 condenser and two-stage furnace deliver measurable energy savings, making it a practical choice for houses around 3 tons of cooling capacity.

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.

Frequently Asked Questions

How does 18 SEER2 compare to older systems I might replace? +
An 18 SEER2 system uses roughly 20 to 30 percent less electricity for cooling than a 13-14 SEER unit from 2005-2010. For a typical three-ton home running 600 hours per cooling season, that translates to 200 to 300 dollars in annual savings depending on local electric rates.
Will this fit my attic space with limited height? +
At 34.5 inches tall and 28.75 inches deep, the A-coil is compact vertically. Confirm your attic has at least 36 inches of clearance above the unit. The 17.5-inch width also fits standard ceiling cavities. Measure your actual opening before ordering.
Is 80% AFUE sufficient for heating, or should I upgrade? +
Eighty percent AFUE is acceptable in moderate climates but wasteful in cold regions. In Minnesota, upgrading to 95% AFUE saves roughly 800 dollars annually. In Texas, the same upgrade saves 200 dollars. Climate zone matters more than the rating alone.
Why is the furnace only two-stage if the condenser is two-stage? +
Furnace two-stage burners modulate at 40 and 100 percent capacity for comfort and efficiency, separate from cooling stages. This setup balances heating flexibility with manufacturing cost. Single-stage furnaces simply cycle on and off, creating temperature swings.
Does the 10-year warranty require annual maintenance? +
Most manufacturers require proof of annual professional service to honor warranty claims. Check your specific Goodman warranty document after registration. Skipping maintenance records can void coverage on component failures.
