The Floating Air Pro X 4-zone runs four rooms from one 208/230V outdoor unit. It carries current R-454B refrigerant and a certified nominal SEER2 of 22 (EER2 12.85, HSPF2 10), 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 36000 BTU at 47F, 22600 at 17F, and back to the full 36000 at 5F - the deep-cold output recovers to match the 47F rating.

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

  • Four zones from one outdoor unit and one 208/230V circuit.
  • Certified nominal SEER2 22 / EER2 12.85 / HSPF2 10, ENERGY STAR certified.
  • 5F heat recovers to the full 36000 BTU 47F output, AHRI cold-climate designated.
  • Current R-454B refrigerant from an established, quality-focused American brand.

Weaknesses

  • Four-zone total capacity is shared; size to the condenser, not four full rooms.
  • Dealer-quoted pricing only, with a part-load efficiency penalty when only one zone is calling.

Frequently asked questions

Can I install the Friedrich Floating Air Pro X 4-Zone 36,000 BTU R-454B 208/230V (FPHMR36A3D) myself, or do I need a pro?
Friedrich Floating Air Pro X 4-Zone 36,000 BTU R-454B 208/230V (FPHMR36A3D) 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 4-Zone 36,000 BTU R-454B 208/230V (FPHMR36A3D) 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 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 X 4-Zone 36,000 BTU R-454B 208/230V (FPHMR36A3D) need?
Published electrical requirements: 230 V voltage, 32 A minimum circuit ampacity, and 35 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 230 ft, and the included line set comes pre-charged for 100 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 4-Zone 36,000 BTU R-454B 208/230V (FPHMR36A3D) 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.
