What is the SEER2 rating of the AC Pro SPHP-Z-V037BB?

The AC Pro SPHP-Z-V037BB is rated at up to 15.4 SEER2 and 10.2 EER2 for cooling and up to 9.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the AC Pro SPHP-Z-V037BB good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 36,000 BTU/h at 5°F with a COP of 1.90, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the AC Pro SPHP-Z-V037BB cost to run per year?

At its rated efficiency it costs about $1,002-$2,491 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,287 in Phoenix and $2,035 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 AC Pro SPHP-Z-V037BB?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses SMAH-Y-36EMBB.

A good fit if…

Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 36,000 BTU/h at 5°F.
It will heat most of the year - its HSPF2 beats 79% of central heat pumps.
You want steady temperatures and quiet running - the compressor varies its speed.

Think twice if…

Cooling cost matters most - its SEER2 is below average for central heat pumps.

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.
