Questions4

What is the best 1.5-ton central heat pump?: On certified efficiency, the Atomi Smart AT2240 leads at 21.2 SEER2 and 8.9 HSPF2. For cold climates the Breeze33 BZ33-INV18OUT2-J has the best efficiency at 5°F (COP 2.30). For very hot summers the AC Pro BH714S18P-**A has the highest EER2 (14.2). The right pick depends on your climate, so compare the lists above.
How many square feet does a 1.5-ton central heat pump cover?: About 600 to 700 sq ft with average insulation: 700 sq ft in a hot and dry climate like Phoenix, 700 sq ft in a hot and humid climate like Houston, 700 sq ft in a mixed climate like Atlanta, 650 sq ft in a cold climate like Chicago, 600 sq ft in a very cold climate like Minneapolis. Cold climates cover less because the heating load is larger.
How much does a 1.5-ton central heat pump cost to run?: A typical 1.5-ton central heat pump (16.5 SEER2, 9.0 HSPF2) uses about $545 of electricity a year in a mixed climate like Atlanta, roughly $45 a month on average. Across U.S. climates it ranges from $545 to $1,064 a year. The most efficient model in this class saves about $44 a year in Atlanta.
Which 1.5-ton central heat pump works best in cold weather?: Look for ENERGY STAR cold-climate certification (83 of 170 qualify). The Breeze33 BZ33-INV18OUT2-J has the highest COP at 5°F in this class (2.30) and delivers 18,800 BTU/h at 5°F. Cold-climate units are often marketed as hyper-heat or low-ambient models.
