What is the SEER2 rating of the Innovair SHV48H2BA?

The Innovair SHV48H2BA is rated at up to 17.5 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 4 certified matchups SEER2 ranges from 15.2-17.5.

Is the Innovair SHV48H2BA good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 48,000 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 Innovair SHV48H2BA cost to run per year?

At its rated efficiency it costs about $1,286-$3,240 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,558 in Phoenix and $2,686 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Innovair SHV48H2BA the same as the NOVAIR LEA48CEN36-O?

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 Innovair SHV48H2BA?

ENERGY STAR lists 4 certified combinations for this outdoor unit. The highest-rated ones use SAV48BDU, SAV48BDA, MMC60H2128B.
