Review methodology

Strengths

  • ENERGY STAR certified with the strongest efficiency numbers of the Select line (21 SEER2, 11.95 EER2).
  • Retains a reasonable 13,700 BTU at 5F, a gentler taper than its Select siblings.
  • Low-GWP R-32 refrigerant plus Friedrich's dealer and warranty support.

Weaknesses

  • Not cold-climate designated, so its 5F output is not a guaranteed cold-climate figure and shouldn't anchor a harsh-winter sizing.
  • 230V and dealer-quoted, without one-click retail pricing.

Frequently asked questions

Can I install the Friedrich Floating Air Select 18,000 BTU R-32 208/230V (FAHFW18A3D / FSHSR18B3D) myself, or do I need a pro?
Friedrich Floating Air Select 18,000 BTU R-32 208/230V (FAHFW18A3D / FSHSR18B3D) 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 Select 18,000 BTU R-32 208/230V (FAHFW18A3D / FSHSR18B3D) keep heating in a cold winter?
The manufacturer publishes 13,700 BTU/h of heating output at 5F. Rated heating operation extends down to -5 F. Certified heating efficiency is 9.8 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 Select 18,000 BTU R-32 208/230V (FAHFW18A3D / FSHSR18B3D) need?
Published electrical requirements: 230 V voltage, 14.5 A minimum circuit ampacity, and 20 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 98.4 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 Select 18,000 BTU R-32 208/230V (FAHFW18A3D / FSHSR18B3D) 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.
