A good fit if…
- Your winters get properly cold - it is ENERGY STAR cold-climate certified, with 18,000 BTU/h at 5°F.
- You want steady temperatures and quiet running - the compressor varies its speed.
Think twice if…
- Cooling cost matters most - its SEER2 is below average for mini-splits.
- You mainly need heat - its HSPF2 is below average for mini-splits.
- You want the newest refrigerant - it uses R-410A, which is being phased down.

Questions
- What is the SEER2 rating of the Friedrich FPHSR24A3A?
- The Friedrich FPHSR24A3A is rated at up to 20.5 SEER2 and 12.2 EER2 for cooling and up to 8.6 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
- Is the Friedrich FPHSR24A3A good for cold climates?
- Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 18,000 BTU/h at 5°F with a COP of 1.75, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
- How much does the Friedrich FPHSR24A3A cost to run per year?
- At its rated efficiency it costs about $531-$1,636 a year in electricity in large U.S. cities, depending on climate and local rates - for example $684 in Phoenix and $1,390 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
- Is the Friedrich FPHSR24A3A the same as the Friedrich FPHSR24A3A-A?
- Yes, as far as the certified ratings go. ENERGY STAR lists 10 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 Friedrich FPHSR24A3A?
- ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses FRIEDRICH FPHFW24A3A.
- What refrigerant does the Friedrich FPHSR24A3A 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.
