What is the SEER2 rating of the Daikin 4MXT36AVJU?

The Daikin 4MXT36AVJU is rated at up to 20.0 SEER2 and 12.0 EER2 for cooling and up to 9.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 3 certified matchups SEER2 ranges from 16.0-20.0.

Is the Daikin 4MXT36AVJU good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 33,200 BTU/h at 5°F with a COP of 1.80, so it is still 1.8 times as efficient as electric resistance heat at that temperature.

How much does the Daikin 4MXT36AVJU cost to run per year?

At its rated efficiency it costs about $809-$2,242 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,009 in Phoenix and $1,881 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Daikin 4MXT36AVJU the same as the Daikin 4MXTH36AVJU?

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.
