Midea Elevate Max 12k R-454B 208/230V Mini-Split
The Max 12k brings the hyper-heat curve to a one-ton head, still climbing to 13,500 BTU at 5F from 12,000 BTU at 47F (with 11,000 BTU at 17F in between), on R-454B. Efficiency remains strong at 28.0 SEER2, though the 13.5 EER2 and 12.7 HSPF2 come down a step from the smaller Max heads. It is the flagship heating profile in a mainstream capacity.

Frequently asked questions
- Can I install the Midea Elevate Max 12,000 BTU R-454B 208/230V (D5FPHAH12XAK / D5CPRAH12AAK) myself, or do I need a pro?
- Midea Elevate Max 12,000 BTU R-454B 208/230V (D5FPHAH12XAK / D5CPRAH12AAK) 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 Midea Elevate Max 12,000 BTU R-454B 208/230V (D5FPHAH12XAK / D5CPRAH12AAK) keep heating in a cold winter?
- The manufacturer publishes 13,500 BTU/h of heating output at 5F. Rated heating operation extends down to -22 F. Certified heating efficiency is 12.7 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 Midea Elevate Max 12,000 BTU R-454B 208/230V (D5FPHAH12XAK / D5CPRAH12AAK) need?
- Published electrical requirements: 230 V voltage, No model-specific value is published on the current consumer product listing minimum circuit ampacity, and No model-specific value is published on the current consumer product listing 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 98 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 Midea Elevate Max 12,000 BTU R-454B 208/230V (D5FPHAH12XAK / D5CPRAH12AAK) carry?
- The manufacturer publishes these warranty tiers: Best case: 10 yr parts / no separate compressor term (timely registration). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
