The Floating Air Pro X 5-zone covers five rooms from one 208/230V outdoor unit. It carries current R-454B refrigerant and a certified nominal SEER2 of 22 (EER2 12, HSPF2 9.5), and it is ENERGY STAR certified and AHRI cold-climate designated.

As with any multi-zone, that certified figure is the all-non-ducted nominal; your real efficiency depends on the heads you attach. Heating is rated at 48000 BTU at 47F, 28200 at 17F, and 36000 at 5F - output is lower in deep cold than at 47F, so plan capacity for your coldest design day.

Friedrich is an established American brand installed by professional dealers and priced by quote.

Structured ratings
Certification: ENERGY STAR certified and ENERGY STAR cold-climate certified. Refrigerant: current low-GWP R-454B. Minimum heating ambient: -13 F.

Strengths

  • Five zones from one outdoor unit and one 208/230V circuit.
  • Certified nominal SEER2 22 / EER2 12 / HSPF2 9.5, ENERGY STAR certified.
  • Strong heating output of 48000 BTU at 47F and 36000 at 5F, AHRI cold-climate designated.

Frequently asked questions

Can I install the Friedrich Floating Air Pro X 5-Zone 42,000 BTU R-454B 208/230V (FPHMR42A3D) myself, or do I need a pro?
Friedrich Floating Air Pro X 5-Zone 42,000 BTU R-454B 208/230V (FPHMR42A3D) 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 X 5-Zone 42,000 BTU R-454B 208/230V (FPHMR42A3D) keep heating in a cold winter?
The manufacturer publishes 36,000 BTU/h of heating output at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 9.5 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 X 5-Zone 42,000 BTU R-454B 208/230V (FPHMR42A3D) need?
Published electrical requirements: 230 V voltage, 36 A minimum circuit ampacity, and 40 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 262 ft, and the included line set comes pre-charged for 125 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 X 5-Zone 42,000 BTU R-454B 208/230V (FPHMR42A3D) 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.
