Specifications

Capacity (BTU/h)6,000 BTU/h

Specs are decoded from the model number and retailer listings. Confirm against the manufacturer submittal sheet before purchase.

Efficiency & refrigerant

This unit uses R-454B, a current low-GWP (A2L) refrigerant that meets the post-2025 EPA AIM Act standard — future-proof for serviceability. A2L refrigerants are mildly flammable, so above a charge threshold the system needs factory leak detection; a certified installer handles this.

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.

Mitsubishi MLZ-KX06NL — questions

How much does the Mitsubishi MLZ-KX06NL cost?

The market median is $1,058 (typical $1,058 to $1,058). 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 ceiling-mounted indoor unit (matched components, labor, permits) costs significantly more, and that install markup is where quotes vary most.

What refrigerant does the MLZ-KX06NL use?

The Mitsubishi MLZ-KX06NL uses R-454B.

Does the Mitsubishi MLZ-KX06NL 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.
