The MXZ-SM60NL is the largest-capacity multi-zone in our catalog: 60,000 BTU across up to eight zones from one 208/230V outdoor unit, for homes whose total load is beyond what the 48k eight-zone can carry. It is a standard SMART MULTI unit with a certified nominal SEER2 of 20, EER2 12, and HSPF2 10.5 - solid efficiency at the top of the capacity range. R-454B refrigerant, ENERGY STAR certified, professional dealer install.

Buyer review snapshot

Best for / skip if

Best for

  • 8-zone projects in the 60k outdoor capacity class.

Install difficulty

Complex professional install
  • Electrical: 208/230V; MCA 55 A; breaker/fuse 90 A.
  • Line set: connection type not sourced; max 492 ft.
  • 8-zone condenser; indoor-head matching and branch layout are part of the job.

Availability and price context

We could not verify a current retail price for this model. Mitsubishi Electric sells through dealers, so we link to contractor quotes rather than a retail price.

Review methodology

Strengths

  • The most capacity here - 60,000 BTU across up to eight zones on one condenser - for larger whole-home loads.
  • Certified nominal SEER2 20 / EER2 12 / HSPF2 10.5, ENERGY STAR certified.
  • Newest SMART MULTI platform; current R-454B refrigerant.
  • Mitsubishi dealer support at maximum whole-home scale.

Weaknesses

  • Professional dealer installation required; the largest eight-zone job, priced by quote.
  • Standard, non-Hyper-Heat - for deep-cold whole-home heating the 48k SM48NLHZ heats better, at less total capacity.
  • Slightly lower rated SEER2 (20) than the 48k SMART MULTI units - the trade for maximum capacity.
  • Part-load penalty when only a few zones are running.

Sizing note: do not just add up the rooms. Multi-zone condensers have a maximum total connected capacity, and connecting more head capacity than the unit is rated for is a common installer mistake that hurts efficiency and comfort. Match total head capacity to the condenser's rating.

Frequently asked questions

Can I install the Mitsubishi Electric MXZ SMART MULTI 8-Zone 60,000 BTU R-454B 208/230V (MXZ-SM60NL) myself, or do I need a pro?
Mitsubishi Electric MXZ SMART MULTI 8-Zone 60,000 BTU R-454B 208/230V (MXZ-SM60NL) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
Will the Mitsubishi Electric MXZ SMART MULTI 8-Zone 60,000 BTU R-454B 208/230V (MXZ-SM60NL) keep heating in a cold winter?
The manufacturer publishes 46,500 BTU/h of heating output at 5F. Rated heating operation extends down to -24 F. Certified heating efficiency is 10.5 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
What electrical circuit does the Mitsubishi Electric MXZ SMART MULTI 8-Zone 60,000 BTU R-454B 208/230V (MXZ-SM60NL) need?
Published electrical requirements: 208/230V voltage, 55 A minimum circuit ampacity, and 90 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
How far can the outdoor unit be from the indoor head?
The published maximum line-set length is 492 ft. Longer runs than the included set allows typically mean added refrigerant and a pro visit, so measure the planned routing before ordering.
What warranty does the Mitsubishi Electric MXZ SMART MULTI 8-Zone 60,000 BTU R-454B 208/230V (MXZ-SM60NL) carry?
The manufacturer publishes these warranty tiers: Standard: 5 yr parts / 7 yr compressor (licensed HVAC contractor installation); Best case: 12 yr parts / 12 yr compressor (owner-occupied residence installed and registered by a Diamond Contractor within 90 days). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
