What is the SEER2 rating of the York YZT60B21?

The York YZT60B21 is rated at up to 16.0 SEER2 and 11.7 EER2 for cooling and up to 7.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 18 certified matchups SEER2 ranges from 15.2-16.0.

Is the York YZT60B21 good for cold climates?

It is not cold-climate certified: none of its matchups meet the ENERGY STAR cold-climate criteria (a COP of at least 1.75 at 5°F among other limits). In places with frequent sub-zero nights, pick a cold-climate 5-ton model.

How much does the York YZT60B21 cost to run per year?

At its rated efficiency it costs about $1,608-$4,748 a year in electricity in large U.S. cities, depending on climate and local rates - for example $2,044 in Phoenix and $4,015 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the York YZT60B21 the same as the Coleman HC19B6021?

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 YZT60B21?

ENERGY STAR lists 18 certified combinations for this outdoor unit. The highest-rated ones use XAHD60JBCN1+JMVT20DC2N1, JHETD60JBCS2N1, XAFD60JBCN1+JMET18DS2N1.

What refrigerant does the York YZT60B21 use?

It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.

A good fit if…

You want a choice of indoor units - 18 certified pairings.

Think twice if…

You often see nights below 0°F - it is not cold-climate certified.
Cooling cost matters most - its SEER2 is below average for central heat pumps.
You mainly need heat - its HSPF2 is below average for central heat pumps.
You want the newest refrigerant - it uses R-410A, which is being phased down.
