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
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
Federal 25C tax credit (now expired for new installs). A qualifying air-source or ductless heat pump may have qualified for the federal 25C Energy Efficient Home Improvement Credit (up to $2,000) if it met the CEE highest-efficiency tier (ENERGY STAR Most Efficient) and was installed as an AHRI-matched system. Important: the federal 25C credit applied only to property placed in service on or before December 31, 2025 — under the One Big Beautiful Bill (Pub. L. 119-21), it does not apply to systems installed after that date. If you installed a qualifying system in 2023–2025, you may still be able to claim it on that year's return — and 2025 claims require the manufacturer's qualified-manufacturer (QM) code.

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
A heat pump should be sized from a Manual J load calculation and matched to the correct indoor coil/air handler — a mismatched pairing voids the warranty and invalidates the rated SEER2/HSPF2. Cold-climate performance depends on the rated capacity at low temperature, not the nameplate tonnage. Installation requires a permit in most jurisdictions and an EPA Section 608-certified technician for the refrigerant work.
Maintenance
Clean or replace the indoor filter every 1–3 months, keep the outdoor coil clear, and have a technician verify refrigerant charge and defrost operation annually. In heating mode, keep the outdoor unit clear of snow and ice.
Goodman GSXN401810 HKSX05XC — questions
How much does the Goodman GSXN401810 HKSX05XC cost?
The market median is $1,573 (typical $1,573 to $1,573). No single retailer lists this exact model for direct purchase right now — that figure is the aggregated market benchmark, equipment only.
Is that the installed price?
No — this is the equipment (box) price. A full installed heat pump systems (matched components, labor, permits) costs significantly more, and that install markup is where quotes vary most.
Does the Goodman GSXN401810 HKSX05XC 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.
