Goodman 1.5 Ton 16 SEER Central Air Conditioner Condenser - R410A Single Stage Review 2026

// Bottom Line

This unit works best for contractors upgrading from GSX16S181 models or homeowners in moderate climates who want solid efficiency without premium pricing. At $1532 for a 1.5-ton 16 SEER condenser, it delivers respectable performance for mid-range residential jobs.

Review

The Goodman GSX160181 occupies the sweet spot between budget air conditioning and modern efficiency standards. This 1.5-ton single-stage condenser delivers 18,000 BTU of cooling capacity with a 16 SEER rating, positioning it as a practical choice for residential replacements and upgrades. At $1532, it undercuts premium brands while offering Energy Star certification and proven Goodman reliability that contractors have trusted for decades.

Performance specifications show this unit cooling efficiently at 16 SEER with a scroll compressor running on R410A refrigerant. The 71.5 dB noise level is typical for single-stage units at full load, though moderately louder than variable-capacity alternatives. Electrical requirements are straightforward, requiring 208/230V single-phase 60Hz with breaker sizing between 12.4 and 20 amps. This flexibility accommodates most residential installations without electrical upgrades.

Pros & Cons

R410A refrigerant requires certified technicians and proper recovery equipment for service

Frequently Asked Questions

Is this a direct replacement for my old GSX16S181? +

Yes, the GSX160181 replaces the GSX16S181 directly. Same tonnage, refrigerant type, and connection sizes mean no coil modifications needed. This makes retrofit projects faster and cheaper than changing to unfamiliar brands.

What electrical service do I need for this unit? +

You'll need 208/230V single-phase 60Hz service. Breaker sizing ranges from 12.4 to 20 amps. Most residential homes already have adequate service, but verify with a licensed electrician before purchasing if you're unsure.

How does 16 SEER compare to newer SEER2 ratings? +

SEER2 typically runs 15-20 percent lower numerically than SEER. This unit's 16 SEER roughly equals approximately 13 SEER2. Check local codes, as some regions now mandate SEER2 compliance for new installations or replacements.

Should I choose this over a variable-capacity condenser? +

Single-stage units cost $300-500 less upfront but run less efficiently during partial-load conditions. Variable-stage models maintain better comfort and lower utility bills in mild weather, though at higher initial cost and complexity.

What happens after my 10-year warranty expires? +

After registration expires, you'll pay out-of-pocket for repairs. Service calls typically run $150-300 plus parts. Most compressors last 15-20 years with proper maintenance, so warranty expiration doesn't mean immediate failure.
