      On certified efficiency, the SLIMAIR SHC24VH2AG leads at 27.5 SEER2 and 14.5 HSPF2. For cold climates the MDV M3OX430-27HFN8-M1 has the best efficiency at 5°F (COP 2.80). For very hot summers the Samsung AM024HCMDCG has the highest EER2 (17.0). The right pick depends on your climate, so compare the lists above.
      How many square feet does a 24,000 BTU mini-split cover?
      About 800 to 1,250 sq ft with average insulation: 1,200 sq ft in a hot and dry climate like Phoenix, 1,200 sq ft in a hot and humid climate like Houston, 1,250 sq ft in a mixed climate like Atlanta, 900 sq ft in a cold climate like Chicago, 800 sq ft in a very cold climate like Minneapolis. Cold climates cover less because the heating load is larger.
      How much does a 24,000 BTU mini-split cost to run?
      A typical 24,000 BTU mini-split (21.6 SEER2, 10.0 HSPF2) uses about $616 of electricity a year in a mixed climate like Atlanta, roughly $51 a month on average. Across U.S. climates it ranges from $591 to $1,257 a year. The most efficient model in this class saves about $170 a year in Atlanta.
      Which 24,000 BTU mini-split works best in cold weather?
      Look for ENERGY STAR cold-climate certification (371 of 430 qualify). The MDV M3OX430-27HFN8-M1 has the highest COP at 5°F in this class (2.80) and delivers 21,400 BTU/h at 5°F. Cold-climate units are often marketed as hyper-heat or low-ambient models.
