What is the SEER2 rating of the York YRACXJ12WHAA?

The York YRACXJ12WHAA is rated at up to 25.0 SEER2 and 14.5 EER2 for cooling and up to 11.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the York YRACXJ12WHAA good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 10,500 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the York YRACXJ12WHAA cost to run per year?

At its rated efficiency it costs about $236-$675 a year in electricity in large U.S. cities, depending on climate and local rates - for example $297 in Phoenix and $569 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the York YRACXJ12WHAA the same as the Hitachi RAC-XJ12WHAA?

Yes, as far as the certified ratings go. ENERGY STAR lists both 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 York YRACXJ12WHAA?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses YORK YRAKXJ12PHAA.
