Fujitsu / AIRSTAGE H-series
Fujitsu AIRSTAGE H-series 14.2k Floor Console R-32 208/230V Mini-Split
The Fujitsu AIRSTAGE H-series Floor-Mounted Console 15k pairs AGUH15KUAS with AOUH12KUBS1 for a professional, dealer-quoted floor-mounted console installation instead of a wall head. It certifies at 14,200 BTU cooling and 18,000 BTU heating at 47F, with 24 SEER2, 12.55 EER2, and 10.95 HSPF2.
Its certified 5F output is 15,800 BTU, matching or beating the 17F rating, so it is a serious cold-weather candidate. The catch is placement: floor consoles need clear floor/wall space and can be blocked by furniture more easily than a high-wall head.

Key ratings
Best-fit use cases
Best for sunrooms, knee-wall rooms, and spaces with limited upper-wall area around 500-700 sq ft, where the owner wants Fujitsu dealer support and the alternate indoor form is worth the installation work.

Model context
- Fujitsu dealer channel
- Fujitsu equipment here is professional-install and quote-based; online purchase restrictions are handled in the purchase-channel policy when that brand fact is sourced.
- Install path
- This is professional-install equipment; no verified current retail offer is attached. Brand purchase-channel policy is shown in the buyer review snapshot.
- Installation context
- Cold-weather output still needs a load calculation and installation clearances, not just the published AHRI rating.
Strengths
- 14,200 BTU of floor-mounted console capacity on current R-32 refrigerant.
- 24 SEER2 / 12.55 EER2 / 10.95 HSPF2 certified efficiency.
- 11,800 BTU at 17F and 15,800 BTU at 5F give real winter numbers to size against.
Weaknesses
- The catch is placement: floor consoles need clear floor/wall space and can be blocked by furniture more easily than a high-wall head.

Frequently asked questions
- Can I install the Fujitsu AIRSTAGE H-series Floor-Mounted Console 14,200 BTU R-32 208/230V (AGUH15KUAS / AOUH12KUBS1) myself, or do I need a pro?
- Fujitsu AIRSTAGE H-series Floor-Mounted Console 14,200 BTU R-32 208/230V (AGUH15KUAS / AOUH12KUBS1) 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 Fujitsu AIRSTAGE H-series Floor-Mounted Console 14,200 BTU R-32 208/230V (AGUH15KUAS / AOUH12KUBS1) keep heating in a cold winter?
- The manufacturer publishes 15,800 BTU/h of heating output at 5F. Rated heating operation extends down to -5 F. Certified heating efficiency is 10.95 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 Fujitsu AIRSTAGE H-series Floor-Mounted Console 14,200 BTU R-32 208/230V (AGUH15KUAS / AOUH12KUBS1) need?
- Published electrical requirements: 208/230V voltage, 14.2 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 98 ft, and the included line set comes pre-charged for 65 ft. Longer runs than the included set allows typically mean added refrigerant and a pro visit, so measure the planned routing before ordering.
