Friedrich / Floating Air Pro
Friedrich Floating Air Pro 12k R-454B 208/230V Mini-Split
The 230V version of the 12k Pro nudges efficiency up to 23 SEER2 while keeping 12.25 EER2 and improving HSPF2 to 10, all on R-454B. Its heating trace is the interesting part: 12,000 BTU at 47F, dipping to 10,800 BTU at 17F, then recovering slightly to 11,000 BTU at 5F. For a mid-size cold-climate room, it holds capacity better than most units its size.

Strengths
- Retains strong low-temperature heat, actually rebounding to 11,000 BTU at 5F after a modest 17F dip.
- 23 SEER2 with 10 HSPF2 makes it efficient in both seasons on a wired-in circuit.
- Cold-climate and ENERGY STAR certified, with R-454B and Friedrich's dealer network behind it.
Weaknesses
- The 17F dip to 10,800 BTU means output is not perfectly flat, so plan the cold-load sizing accordingly.
- Sold through dealers only, so there is no one-click price and a 230V circuit is required.

Frequently asked questions
- Can I install the Friedrich Floating Air Pro 12,000 BTU R-454B 208/230V (FAHFW12A3D / FPHSR12A3D) myself, or do I need a pro?
- Friedrich Floating Air Pro 12,000 BTU R-454B 208/230V (FAHFW12A3D / FPHSR12A3D) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
- Will the Friedrich Floating Air Pro 12,000 BTU R-454B 208/230V (FAHFW12A3D / FPHSR12A3D) keep heating in a cold winter?
- The manufacturer publishes 11,000 BTU/h of heating output at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 10 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
- What electrical circuit does the Friedrich Floating Air Pro 12,000 BTU R-454B 208/230V (FAHFW12A3D / FPHSR12A3D) need?
- Published electrical requirements: 230 V voltage, 10.5 A minimum circuit ampacity, and 15 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
- How far can the outdoor unit be from the indoor head?
- The published maximum line-set length is 65.6 ft, and the included line set comes pre-charged for 24.6 ft. Longer runs than the included set allows typically mean added refrigerant and a pro visit, so measure the planned routing before ordering.
- What warranty does the Friedrich Floating Air Pro 12,000 BTU R-454B 208/230V (FAHFW12A3D / FPHSR12A3D) carry?
- The manufacturer publishes these warranty tiers: Best case: 7 yr parts / 10 yr compressor (registration). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
