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 certified at 36000 BTU at 47F, 22600 at 17F and the full 36000 at 5F.

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

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 AHRI/ENERGY STAR certification lists 36,000 BTU/h of heating capacity 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 from the outdoor unit to one indoor head is 82 ft. The combined piping limit across all heads is 230 ft. The outdoor unit's factory charge covers up to 100 ft of line; longer runs need added refrigerant. 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: Registered: 7 yr parts / 10 yr compressor (registration). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
