Mitsubishi Electric / P-Series PEAD Horizontal Ducted
Mitsubishi P-Series PEAD Horizontal Ducted 12k Concealed Ducted 208/230V Mini-Split
The P-Series PEAD Horizontal Ducted 12k is Mitsubishi's concealed-ducted route for hiding the indoor unit above a ceiling and feeding one room or a small zone through short ducts. It certifies at 12,000 BTU cooling with 18,000 BTU of 47F heat. The standard outdoor unit favors efficiency and moderate-climate balance, with SEER2 20, EER2 14.4, HSPF2 9.5, and 7,900 BTU at 5F.
The catch is duct design: SEER2 20 and HSPF2 9.5 are certified for this exact pairing, but a cramped return, high static pressure, or inaccessible service panel can make a ducted mini-split feel worse than the numbers suggest.

Model context
- Mitsubishi dealer channel
- Mitsubishi Electric equipment is sold through its dealer network; installed price depends on the local contractor.
- Install path
- This is professional-install equipment; price it with an installed quote.
- Installation context
- Concealed ducted installs depend on duct layout, static pressure, return-air path, condensate routing, and service access.
Strengths
- 20 SEER2 / 14.4 EER2 / 9.5 HSPF2 certified efficiency.
- 12,000 BTU hidden ducted capacity without a full central air handler.
- 9,200 BTU at 17F and 7,900 BTU at 5F give real heating numbers to size against.
Weaknesses
- Not AHRI cold-climate designated; 5F heat falls to 7,900 BTU, so size carefully in northern winters.

Frequently asked questions
- Can I install the Mitsubishi Electric P-Series PEAD Horizontal Ducted 12,000 BTU R-454B 208/230V (PEAD-AA12NL / PUZ-AK12NL) myself, or do I need a pro?
- Mitsubishi Electric P-Series PEAD Horizontal Ducted 12,000 BTU R-454B 208/230V (PEAD-AA12NL / PUZ-AK12NL) 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 P-Series PEAD Horizontal Ducted 12,000 BTU R-454B 208/230V (PEAD-AA12NL / PUZ-AK12NL) keep heating in a cold winter?
- The AHRI/ENERGY STAR certification lists 7,900 BTU/h of heating capacity at 5F. Rated heating operation extends down to -4 F. Certified heating efficiency is 9.5 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 P-Series PEAD Horizontal Ducted 12,000 BTU R-454B 208/230V (PEAD-AA12NL / PUZ-AK12NL) need?
- Published electrical requirements: 230 V voltage, 16 A minimum circuit ampacity, and 27 A maximum breaker or fuse sizing. Calculated recommendation: 25 A is the nearest standard breaker size at or below the published 27 A maximum. 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 100 ft. The outdoor unit's factory charge covers up to 100 ft of line; longer runs need added refrigerant. Measure the planned routing before ordering.
- What warranty does the Mitsubishi Electric P-Series PEAD Horizontal Ducted 12,000 BTU R-454B 208/230V (PEAD-AA12NL / PUZ-AK12NL) carry?
- The manufacturer publishes these warranty tiers: Base: 5 yr parts / 7 yr compressor (licensed HVAC contractor installation). Score uses Base.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
