Midea Elevate Max 18k R-454B 208/230V Mini-Split
The largest Max head scales the hyper-heat idea to 1.5 tons: certified heating of 20,000 BTU at 47F, 19,300 BTU at 17F and 22,600 BTU at 5F on R-454B. It backs that with a very high 15.2 HSPF2, plus 24.5 SEER2 and 14.0 EER2. For a unit this size, more capacity at 5F than at 47F is exactly what a cold-climate buyer wants.

Model context
- Structured ratings
- Certification: ENERGY STAR certified and AHRI cold-climate designated. Refrigerant: current low-GWP R-454B. Minimum heating ambient: -22 F.
Strengths
- 22,600 BTU certified at 5F, above its 47F rating - real deep-cold capacity at 1.5 tons.
- Excellent 15.2 HSPF2 for a head this large, meaning low seasonal heating cost.
- ENERGY STAR certified, cold-climate designated, low-GWP R-454B.
Weaknesses
- 24.5 SEER2 is the lowest of the Max heads, so its cooling efficiency, while good, is not class-leading.
- Larger capacity means a bigger 230V install job.

Frequently asked questions
- Can I install the Midea Elevate Max 18,000 BTU R-454B 208/230V (D5FPHAH18XAK / D5CPRAH18AA) myself, or do I need a pro?
- Midea Elevate Max 18,000 BTU R-454B 208/230V (D5FPHAH18XAK / D5CPRAH18AA) 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 18,000 BTU R-454B 208/230V (D5FPHAH18XAK / D5CPRAH18AA) keep heating in a cold winter?
- The AHRI/ENERGY STAR certification lists 22,600 BTU/h of heating capacity at 5F. Rated heating operation extends down to -22 F. Certified heating efficiency is 15.2 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 18,000 BTU R-454B 208/230V (D5FPHAH18XAK / D5CPRAH18AA) need?
- Published electrical requirements: 230 V voltage. 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. Measure the planned routing before ordering.
- What warranty does the Midea Elevate Max 18,000 BTU R-454B 208/230V (D5FPHAH18XAK / D5CPRAH18AA) carry?
- The manufacturer publishes these warranty tiers: Registered: 10 yr parts / no separate compressor term (timely registration). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
