ACiQ ACIQ-06ZPL-HP230B vs Pioneer YN009GMSI24RPG
Ranking criteria: for each brand we picked its single-zone outdoor unit in the 9,000 BTU (0.75 ton) class with the highest certified HSPF2, and show that unit's highest-HSPF2 indoor pairing. Other pairings and models from each brand may rate differently. Data: ENERGY STAR certification records retrieved 2026-10-17. Rankings are calculated from published ratings only. They are not hands-on tests or installations, and noise, price, warranty, installer availability and reliability are not considered (not in the data).
- Heating efficiency: the ACiQ ACIQ-06ZPL-HP230B pairing has the higher HSPF2 (13.6 vs 11.8).
- Cooling efficiency: the ACiQ ACIQ-06ZPL-HP230B pairing has the higher SEER2 (26.5 vs 22.1).
- Cold weather: at 5°F the Pioneer YN009GMSI24RPG pairing is rated for more heat (8,000 vs 7,500 BTU/h).
- Per 1,000 heating full-load hours, the estimated electricity difference is about $76 at the U.S. average rate.

Cost estimates: cooling kWh ≈ cooling capacity × full-load hours ÷ SEER2 ÷ 1,000; heating kWh ≈ 47°F heating capacity × full-load hours ÷ HSPF2 ÷ 1,000. "Per 1,000 full-load hours" is a yardstick for comparing systems, not a prediction of your bill; your hours depend on climate, house and settings. Rate: U.S. average residential 18.31¢/kWh (EIA, July 2026 (preliminary)).
