Questions6
What is the SEER2 rating of the TOSOT TWH09PD32AO?
The TOSOT TWH09PD32AO is rated at up to 26.0 SEER2 and 15.0 EER2 for cooling and up to 10.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 7 certified matchups SEER2 ranges from 22.0-26.0.
Is the TOSOT TWH09PD32AO good for cold climates?
Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 10,000 BTU/h at 5°F with a COP of 2.15, so it is still 2.2 times as efficient as electric resistance heat at that temperature.
How much does the TOSOT TWH09PD32AO cost to run per year?
At its rated efficiency it costs about $167-$600 a year in electricity in large U.S. cities, depending on climate and local rates - for example $227 in Phoenix and $517 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
Is the TOSOT TWH09PD32AO the same as the TOSOT TW09HP32A2DO?
Yes, as far as the certified ratings go. ENERGY STAR lists 3 model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
Which indoor units work with the TOSOT TWH09PD32AO?
ENERGY STAR lists 7 certified combinations for this outdoor unit. The highest-rated ones use TWH09PD32AI, TWH09KD32AI, TTH09D32AI.
What refrigerant does the TOSOT TWH09PD32AO use?

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.
