Comparable 1.5-ton systems from other brands
Same size, different brands, cheapest first. An “outdoor unit only” price doesn't include the matched indoor unit — don't compare it 1:1 against a two-piece system. Pick a brand, then open it to compare the price across every retailer that lists it.

Efficiency & refrigerant
SEER2 14.5 is the current cooling-efficiency rating (the 2023 successor to SEER, measured under more realistic duct conditions). A higher SEER2 means lower cooling bills for the same comfort; current federal minimums are 13.4–14.3 SEER2 depending on region and equipment type. Refrigerant type was not published for this listing. Note the 2025 transition: new residential systems must now use low-GWP refrigerant (R-454B or R-32) under the EPA AIM Act, while existing R-410A units remain serviceable.
Rebates & tax credits
This category does not have its own line in the federal 25C tax credit. Some matched-system components may still factor into a qualifying installation — confirm with your installer. See the federal credit details →
This is not tax advice. We do not know this exact model's certified efficiency rating, so we cannot say it qualifies for any specific amount. Eligibility depends on the installed system's AHRI-matched rating, your tax liability, and the home being your residence. Always confirm with your installer and a tax advisor.

Matched systems (AHRI)
For ducted split systems, the rated efficiency only holds for AHRI-certified matched combinations of outdoor unit, coil, and air handler. Look up certified matches for this model in the official directory:

A retailer "system bundle" is not proof of an AHRI reference number. Verify the match in the AHRI Directory.
Before you buy or install
Size HVAC equipment from a Manual J load calculation, not square-footage rules of thumb, and confirm every matched component (indoor/outdoor) lines up — a mismatch voids the warranty and the rated efficiency. Most installations require a permit and, where refrigerant is involved, an EPA Section 608-certified technician. This is not a DIY job.
Maintenance
Replace or clean filters on schedule, keep coils and condensate drains clear, and have the system professionally serviced annually to hold its rated efficiency.
Goodman GSXB401810 - CAPTA1818A4 - GM9S800403AN — questions
How much does the Goodman GSXB401810 - CAPTA1818A4 - GM9S800403AN cost?
One retailer currently lists it at $3,358. That's the equipment price only — installation (labor, matched coil or air handler, permits) adds significantly more.
Is that the installed price?
No — this is the equipment (box) price. A full installed equipment (matched components, labor, permits) costs significantly more, and that install markup is where quotes vary most.
Does the Goodman GSXB401810 - CAPTA1818A4 - GM9S800403AN qualify for a federal tax credit?
The federal 25C credit applied only to systems placed in service on or before December 31, 2025, so it does not apply to new installs after that date. State and utility rebates (via DSIRE) may still apply — confirm eligibility with your installer and a tax advisor.
