      A good fit if…

      • You want a choice of indoor units - 22 certified pairings.

      Think twice if…

      • You often see nights below 0°F - it is not cold-climate certified.
      • You mainly need heat - its HSPF2 is below average for central heat pumps.
      • You want the newest refrigerant - it uses R-410A, which is being phased down.
      • Comfort and noise matter - a single-stage compressor runs only full-on or off.

      Questions5
      What is the SEER2 rating of the MRCOOL MHP17024A-**A?
      The MRCOOL MHP17024A-**A is rated at up to 17.0 SEER2 and 14.0 EER2 for cooling and up to 8.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 22 certified matchups SEER2 ranges from 15.6-17.0.
      Is the MRCOOL MHP17024A-**A 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 MRCOOL MHP17024A-**A cost to run per year?
      At its rated efficiency it costs about $647-$1,710 a year in electricity in large U.S. cities, depending on climate and local rates - for example $794 in Phoenix and $1,427 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 MRCOOL MHP17024A-**A?
      ENERGY STAR lists 22 certified combinations for this outdoor unit. The highest-rated ones use MCHP30BNPA*+TDR+TXV, MCVP30ANPA+TDR+TXV, MCVP30BNPA+TDR+TXV.
      What refrigerant does the MRCOOL MHP17024A-**A use?
      It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

      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.
