What is the SEER2 rating of the Daikin DH5SEA3010A?

The Daikin DH5SEA3010A is rated at up to 15.2 SEER2 and 12.5 EER2 for cooling and up to 7.8 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.

Is the Daikin DH5SEA3010A 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 2.5-ton model.

How much does the Daikin DH5SEA3010A cost to run per year?

At its rated efficiency it costs about $884-$2,325 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,084 in Phoenix and $1,939 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Daikin DH5SEA3010A the same as the Goodman GLZS5BA3010A?

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 Daikin DH5SEA3010A?

ENERGY STAR lists 2 certified combinations for this outdoor unit. The highest-rated ones use AMST30BU1300A, AMST30BU1300B.

2.5-ton central heat pump · DH5SE

Daikin DH5SEA3010A

Below average cooling and heating efficiency for a 2.5-ton central heat pump, but not rated for cold climates.

Ranks #186 of 199 2.5 ton central heat pumps for cooling efficiency, and costs about $976 a year to run in a mixed climate like Atlanta.

A good fit if…

You want a certified 2.5-ton central 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 central heat pumps.
You mainly need heat - its HSPF2 is below average for central heat pumps.
Comfort and noise matter - a single-stage compressor runs only full-on or off.
