What is the SEER2 rating of the AIR-CON ABZCI4H4S09?

The AIR-CON ABZCI4H4S09 is rated at up to 27.5 SEER2 and 15.5 EER2 for cooling and up to 10.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the AIR-CON ABZCI4H4S09 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 7,000 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 AIR-CON ABZCI4H4S09 cost to run per year?

At its rated efficiency it costs about $155-$516 a year in electricity in large U.S. cities, depending on climate and local rates - for example $206 in Phoenix and $442 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the AIR-CON ABZCI4H4S09 the same as the Westinghouse WHZ09SZA21S?

Yes, as far as the certified ratings go. ENERGY STAR lists 3 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 AIR-CON ABZCI4H4S09?

ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses ABZEM4H4S09.

What refrigerant does the AIR-CON ABZCI4H4S09 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.
