      2-ton central heat pump · Elite EL19KPV SERIES

      Lennox EL19KPV-024-230A

      Excellent cooling efficiency and average heating efficiency for a 2-ton central heat pump, but not rated for cold climates.

      Ranks #29 of 331 2 ton central heat pumps for cooling efficiency, and costs about $672 a year to run in a mixed climate like Atlanta.

      A good fit if…

      • You want low cooling bills - its SEER2 beats 94% of central heat pumps.
      • You want steady temperatures and quiet running - the compressor varies its speed.
      • You want a choice of indoor units - 221 certified pairings.

      Think twice if…

      • You often see nights below 0°F - it is not cold-climate certified.

      Questions5
      What is the SEER2 rating of the Lennox EL19KPV-024-230A?
      The Lennox EL19KPV-024-230A is rated at up to 20.0 SEER2 and 13.0 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 221 certified matchups SEER2 ranges from 15.2-20.0.
      Is the Lennox EL19KPV-024-230A good for cold climates?
      It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 2-ton model.
      How much does the Lennox EL19KPV-024-230A cost to run per year?
      At its rated efficiency it costs about $561-$1,637 a year in electricity in large U.S. cities, depending on climate and local rates - for example $711 in Phoenix and $1,382 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Which indoor units work with the Lennox EL19KPV-024-230A?
      ENERGY STAR lists 221 certified combinations for this outdoor unit. The highest-rated ones use CK40DT-42B-**+TDR, CK40[C,U]T-24B-**+TDR, CK40[C,U]T-24A-**+TDR.
      What refrigerant does the Lennox EL19KPV-024-230A use?
      It uses R-454B.

      Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
