What is the SEER2 rating of the Innovair SOV24H2BA?

The Innovair SOV24H2BA is rated at up to 18.1 SEER2 and 11.0 EER2 for cooling and up to 10.4 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 10 certified matchups SEER2 ranges from 15.3-18.1.

Is the Innovair SOV24H2BA good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 21,600 BTU/h at 5°F with a COP of 2.14, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the Innovair SOV24H2BA cost to run per year?

At its rated efficiency it costs about $621-$1,547 a year in electricity in large U.S. cities, depending on climate and local rates - for example $750 in Phoenix and $1,280 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Which indoor units work with the Innovair SOV24H2BA?

ENERGY STAR lists 10 certified combinations for this outdoor unit. The highest-rated ones use SAV24BDA, SAV24BDU, SWV24BDA.
