What is the SEER2 rating of the York PHE6B4824?

The York PHE6B4824 is rated at up to 15.2 SEER2 and 12.0 EER2 for cooling and up to 7.2 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the York PHE6B4824 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 4-ton model.

How much does the York PHE6B4824 cost to run per year?

At its rated efficiency it costs about $1,439-$3,963 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,790 in Phoenix and $3,324 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the York PHE6B4824 the same as the Luxaire PHG6B481002X4?

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.

What refrigerant does the York PHE6B4824 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 certified 4-ton packaged heat pump at a typical efficiency level.

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 packaged heat pumps.
You mainly need heat - its HSPF2 is below average for packaged heat pumps.
You want the newest refrigerant - it uses R-410A, which is being phased down.
