A good fit if…

  • You want a choice of indoor units - 39 certified pairings.

Think twice if…

  • You often see nights below 0°F - it is not cold-climate certified.
  • Cooling cost matters most - its SEER2 is below average for central heat pumps.
  • You mainly need heat - its HSPF2 is below average for central heat pumps.
  • Comfort and noise matter - a single-stage compressor runs only full-on or off.

Questions6
What is the SEER2 rating of the Lennox EL16KP1-030-230A?
The Lennox EL16KP1-030-230A is rated at up to 16.0 SEER2 and 13.4 EER2 for cooling and up to 8.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 39 certified matchups SEER2 ranges from 15.2-16.0.
Is the Lennox EL16KP1-030-230A 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 2.5-ton model.
How much does the Lennox EL16KP1-030-230A cost to run per year?
At its rated efficiency it costs about $855-$2,108 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,029 in Phoenix and $1,743 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Is the Lennox EL16KP1-030-230A the same as the Lennox ML14KP1-030-230A?
Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
Which indoor units work with the Lennox EL16KP1-030-230A?
ENERGY STAR lists 39 certified combinations for this outdoor unit. The highest-rated ones use CK40[C,U]T-36B-**+TDR, CBK48MVT-036-230-, CBK47UHET-036-230-.
What refrigerant does the Lennox EL16KP1-030-230A 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.
