What is the SEER2 rating of the York YPAS36BUFASDQ1?

The York YPAS36BUFASDQ1 is rated at up to 21.0 SEER2 and 13.0 EER2 for cooling and up to 11.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 4 certified matchups SEER2 ranges from 18.0-21.0.

Is the York YPAS36BUFASDQ1 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 35,000 BTU/h at 5°F with a COP of 2.30, so it is still 2.3 times as efficient as electric resistance heat at that temperature.

How much does the York YPAS36BUFASDQ1 cost to run per year?

At its rated efficiency it costs about $804-$2,057 a year in electricity in large U.S. cities, depending on climate and local rates - for example $978 in Phoenix and $1,709 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the York YPAS36BUFASDQ1 the same as the Hitachi PAS-36BUFASDQ1?

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 YPAS36BUFASDQ1?

ENERGY STAR lists 4 certified combinations for this outdoor unit. The highest-rated ones use YORK YPCIB36UFA1DQ, YORK YPPKB36UFA1DQ, YORK YPPIMB36UFA1DQ.
