What is the SEER2 rating of the Carrier 27VNA324A*030?

The Carrier 27VNA324A*030 is rated at up to 23.0 SEER2 and 14.0 EER2 for cooling and up to 10.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with; across its 430 certified matchups SEER2 ranges from 18.0-23.0.

Is the Carrier 27VNA324A*030 good for cold climates?

Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 23,000 BTU/h at 5°F with a COP of 2.10, so it is still 2.1 times as efficient as electric resistance heat at that temperature.

How much does the Carrier 27VNA324A*030 cost to run per year?

At its rated efficiency it costs about $475-$1,573 a year in electricity in large U.S. cities, depending on climate and local rates - for example $627 in Phoenix and $1,347 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.

Is the Carrier 27VNA324A*030 the same as the Bryant 293VAN024**AA?

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 Carrier 27VNA324A*030?

ENERGY STAR lists 430 certified combinations for this outdoor unit. The highest-rated ones use CVAMA4421XMA*+UI, CVAMA3217XMA*+UI, CVAVA3817XMA*+UI.
