What is the SEER2 rating of the DuraSTAR DRU1H24S2A?

The DuraSTAR DRU1H24S2A is rated at up to 18.4 SEER2 and 10.8 EER2 for cooling and up to 10.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 53 certified matchups SEER2 ranges from 15.2-18.4.

Is the DuraSTAR DRU1H24S2A good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 21,600 BTU/h at 5°F with a COP of 1.96, so it is still 2.0 times as efficient as electric resistance heat at that temperature.

How much does the DuraSTAR DRU1H24S2A cost to run per year?

At its rated efficiency it costs about $611-$1,530 a year in electricity in large U.S. cities, depending on climate and local rates - for example $739 in Phoenix and $1,267 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 DuraSTAR DRU1H24S2A?
