      A good fit if…

      • You want low cooling bills - its SEER2 beats 91% of central heat pumps.
      • Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 37,600 BTU/h at 5°F.
      • It will heat most of the year - its HSPF2 beats 70% of central heat pumps.
      • You want steady temperatures and quiet running - the compressor varies its speed.

      Think twice if…

      • Nothing stands out - its ratings have no weak spot for its class.

      Questions6
      What is the SEER2 rating of the Carrier 27VNA048A*030?
      The Carrier 27VNA048A*030 is rated at up to 19.5 SEER2 and 10.5 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 376 certified matchups SEER2 ranges from 15.5-19.5.
      Is the Carrier 27VNA048A*030 good for cold climates?
      Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 37,600 BTU/h at 5°F with a COP of 2.20, so it is still 2.2 times as efficient as electric resistance heat at that temperature.
      How much does the Carrier 27VNA048A*030 cost to run per year?
      At its rated efficiency it costs about $1,148-$3,274 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,443 in Phoenix and $2,757 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
      Is the Carrier 27VNA048A*030 the same as the Bryant 290VAN048**AA?
      Yes, as far as the certified ratings go. ENERGY STAR lists 4 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 27VNA048A*030?
      ENERGY STAR lists 376 certified combinations for this outdoor unit. The highest-rated ones use FE5BNBD60L*+UI, CVAMA6124XMA*+UI, CVAVA6121XMA*+UI.
      What refrigerant does the Carrier 27VNA048A*030 use?
      It uses R-454B.

      Estimates use the unit's rated SEER2 and HSPF2, full-load hours derived from NOAA 1991-2020 degree days, average residential electricity prices from the U.S. EIA (12 months to July 2026) and fuel prices from EIA (2025 for natural gas, week of 2026-10-05 for propane and heating oil). Very cold days that need backup heat are not modelled. Federal minimum for comparison: 14.3 SEER2 / 7.5 HSPF2.
