A good fit if…

  • You want a choice of indoor units - 20 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.
  • You want the newest refrigerant - it uses R-410A, which is being phased down.

Questions5
What is the SEER2 rating of the EVCON RHP15030B21?
The EVCON RHP15030B21 is rated at up to 15.2 SEER2 and 12.0 EER2 for cooling and up to 8.1 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
Is the EVCON RHP15030B21 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 EVCON RHP15030B21 cost to run per year?
At its rated efficiency it costs about $895-$2,262 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,085 in Phoenix and $1,876 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 EVCON RHP15030B21?
ENERGY STAR lists 20 certified combinations for this outdoor unit. The highest-rated ones use XAFC36DBAN1+JME16C2SN1, XAFB36DBAN1+JME12B2SN1, XAFC36DBAN1+JME12C2SN1.
What refrigerant does the EVCON RHP15030B21 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.
