What is the SEER2 rating of the Haier 1U24T3PS*HE?

The Haier 1U24T3PS*HE is rated at up to 18.5 SEER2 and 12.3 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 119 certified matchups SEER2 ranges from 15.2-18.5.

Is the Haier 1U24T3PS*HE good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 23,400 BTU/h at 5°F with a COP of 1.85, so it is still 1.9 times as efficient as electric resistance heat at that temperature.

How much does the Haier 1U24T3PS*HE cost to run per year?

At its rated efficiency it costs about $608-$1,538 a year in electricity in large U.S. cities, depending on climate and local rates - for example $738 in Phoenix and $1,275 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 Haier 1U24T3PS*HE?

ENERGY STAR lists 119 certified combinations for this outdoor unit. The highest-rated ones use NAM30E3TA5, NAM24V1TA5, NAM30V2TA5.

Questions5

What is the SEER2 rating of the Haier 1U24T3PS*HE?: The Haier 1U24T3PS*HE is rated at up to 18.5 SEER2 and 12.3 EER2 for cooling and up to 10.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 119 certified matchups SEER2 ranges from 15.2-18.5.
Is the Haier 1U24T3PS*HE good for cold climates?: Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 23,400 BTU/h at 5°F with a COP of 1.85, so it is still 1.9 times as efficient as electric resistance heat at that temperature.
How much does the Haier 1U24T3PS*HE cost to run per year?: At its rated efficiency it costs about $608-$1,538 a year in electricity in large U.S. cities, depending on climate and local rates - for example $738 in Phoenix and $1,275 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 Haier 1U24T3PS*HE?: ENERGY STAR lists 119 certified combinations for this outdoor unit. The highest-rated ones use NAM30E3TA5, NAM24V1TA5, NAM30V2TA5.
What refrigerant does the Haier 1U24T3PS*HE use?: It uses R-454B.
