Midea / Midea Easy Pro Extreme Heat
Midea Easy Pro Extreme Heat 24k R-454B 208/230V Mini-Split
The 2-ton Extreme Heat pushes serious numbers: certified heating of 29,000 BTU at 47F, 22,200 BTU at 17F and 24,200 BTU at 5F on R-454B. Efficiency reads 21.0 SEER2 and 13.0 EER2, but the standout is the 13.5 HSPF2 - unusually high for a head this large. It is built to carry a big cold-climate load without flinching.

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
- Enormous low-temperature heat: 24,200 BTU certified at 5F, above its 17F figure.
- 13.5 HSPF2 is excellent for a 2-ton unit, keeping seasonal heating costs in check.
- ENERGY STAR certified, cold-climate designated, low-GWP R-454B.
Weaknesses
- 21.0 SEER2 is on the low side for the family, so summer efficiency is only fair.

Frequently asked questions
- Can I install the Midea Easy Pro Extreme Heat 24,000 BTU R-454B 208/230V (MSEHU-H24B-2A / MO1HS-H24B-2A) myself, or do I need a pro?
- Midea Easy Pro Extreme Heat 24,000 BTU R-454B 208/230V (MSEHU-H24B-2A / MO1HS-H24B-2A) 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 Easy Pro Extreme Heat 24,000 BTU R-454B 208/230V (MSEHU-H24B-2A / MO1HS-H24B-2A) keep heating in a cold winter?
- The AHRI/ENERGY STAR certification lists 24,200 BTU/h of heating capacity at 5F. Rated heating operation extends down to -22 F. Certified heating efficiency is 13.5 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 Midea Easy Pro Extreme Heat 24,000 BTU R-454B 208/230V (MSEHU-H24B-2A / MO1HS-H24B-2A) 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 213 ft. Measure the planned routing before ordering.
- What warranty does the Midea Easy Pro Extreme Heat 24,000 BTU R-454B 208/230V (MSEHU-H24B-2A / MO1HS-H24B-2A) carry?
- The manufacturer publishes these warranty tiers: Base: 5 yr parts / 7 yr compressor (base coverage); Registered: 12 yr parts / 12 yr compressor (online registration at mideacomfort.us within 60 days of installation). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
