A good fit if…
- You want low cooling bills - its SEER2 beats 85% of central heat pumps.
- Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 42,000 BTU/h at 5°F.
- You want steady temperatures and quiet running - the compressor varies its speed.
Think twice if…
- You mainly need heat - its HSPF2 is below average for central heat pumps.
- You want the newest refrigerant - it uses R-410A, which is being phased down.

Questions
- What is the SEER2 rating of the Friedrich FRP18AZ48AJVC?
- The Friedrich FRP18AZ48AJVC is rated at up to 19.0 SEER2 and 12.0 EER2 for cooling and up to 8.5 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
- Is the Friedrich FRP18AZ48AJVC good for cold climates?
- Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 42,000 BTU/h at 5°F with a COP of 1.80, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
- How much does the Friedrich FRP18AZ48AJVC cost to run per year?
- At its rated efficiency it costs about $1,120-$3,454 a year in electricity in large U.S. cities, depending on climate and local rates - for example $1,444 in Phoenix and $2,934 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 Friedrich FRP18AZ48AJVC?
- ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses FRHMVZ6021SEACA.
- What refrigerant does the Friedrich FRP18AZ48AJVC use?
- It uses R-410A. R-410A is being phased down under the EPA AIM Act, and new systems are moving to R-454B and R-32.
