What is the SEER2 rating of the ApooDr AHU3G-60HFN-B?

The ApooDr AHU3G-60HFN-B is rated at up to 17.5 SEER2 and 12.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the ApooDr AHU3G-60HFN-B good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 54,000 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 ApooDr AHU3G-60HFN-B cost to run per year?

At its rated efficiency it costs about $1,447-$3,699 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,761 in Phoenix and $3,072 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 ApooDr AHU3G-60HFN-B?

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.
