A good fit if…
- Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 31,000 BTU/h at 5°F.
- You want steady temperatures and quiet running - the compressor varies its speed.
Think twice if…
- 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.

Questions
- What is the SEER2 rating of the Daikin DZ6VSA481EA?
- The Daikin DZ6VSA481EA is rated at up to 17.0 SEER2 and 10.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
- Is the Daikin DZ6VSA481EA good for cold climates?
- Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 31,000 BTU/h at 5°F with a COP of 2.00, so it is still 2.0 times as efficient as electric resistance heat at that temperature.
- How much does the Daikin DZ6VSA481EA cost to run per year?
- At its rated efficiency it costs about $1,216-$3,266 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,502 in Phoenix and $2,730 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
- Is the Daikin DZ6VSA481EA the same as the Amana ASZS60481EA?
- 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 Daikin DZ6VSA481EA?
- ENERGY STAR lists 4 certified combinations for this outdoor unit. The highest-rated one uses CA*EA6030*4A.
- What refrigerant does the Daikin DZ6VSA481EA 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.
