      Questions4
      What is the best under 1.5-ton packaged heat pump?
      On certified efficiency, the Multi MFG 12SPV0-HP-X-D leads at 17.1 SEER2 and 8.6 HSPF2. For cold climates the Ephoca AVK19N3H2 has the best efficiency at 5°F (COP 2.30). For very hot summers the Ephoca AVK19N3H2 has the highest EER2 (11.7). The right pick depends on your climate, so compare the lists above.
      How many square feet does a under 1.5-ton packaged heat pump cover?
      About 400 to 450 sq ft with average insulation: 450 sq ft in a hot and dry climate like Phoenix, 450 sq ft in a hot and humid climate like Houston, 450 sq ft in a mixed climate like Atlanta, 450 sq ft in a cold climate like Chicago, 400 sq ft in a very cold climate like Minneapolis. Cold climates cover less because the heating load is larger.
      How much does a under 1.5-ton packaged heat pump cost to run?
      A typical under 1.5-ton packaged heat pump (15.4 SEER2, 9.2 HSPF2) uses about $369 of electricity a year in a mixed climate like Atlanta, roughly $31 a month on average. Across U.S. climates it ranges from $369 to $700 a year. The most efficient model in this class saves about $0 a year in Atlanta.
      Which under 1.5-ton packaged heat pump works best in cold weather?
      Look for ENERGY STAR cold-climate certification (9 of 9 qualify). The Ephoca AVK19N3H2 has the highest COP at 5°F in this class (2.30) and delivers 8,200 BTU/h at 5°F. Cold-climate units are often marketed as hyper-heat or low-ambient models.
