Capacity boost – Steps up to 12.4 kBTU cooling and 11 kBTU heat-pump output, enough for ~450-550 ft² guest rooms.
Energy & refrigerant – Low-GWP R-32; EER ≈ 10.5 is competitive in the 12 k size, driven by a DC variable-speed indoor fan.
Guest controls – Auto-dimming LED pad, four temperature-limit presets, Constant-Fan for steady background sound.
Serviceability – Slide-in chassis leaves sleeve & grille in the wall; 9-code on-board diagnostics speed troubleshooting.
Moisture & freeze management – Slinger-ring pump-out plus hidden fresh-air vent (RAKVENTH) help keep coils dry and prevent freeze-ups.
Hotpoint started more than a century ago with two relentless inventors who turned everyday chores into plug-in convenience. That roll-up-your-sleeves DNA is alive in the new A-Series slide-in PTACs: tough, easy to service, and packed with the safeguards today’s properties demand. The 12 kBTU AHHS12D3XXA is the “mid-size muscle” of the line, built for 400- to 550-ft² rooms that need strong cooling and dependable heat all year.
One-hour swap-outs – Slide-in chassis + included cord mean most change-outs finish before housekeeping is done.
Fleet interchangeability – Every A-Series model shares the same 42 × 16 × 13¾″ sleeve, grille, filters, and thermostat kits.
Low-GWP refrigerant – R-32 meets emerging environmental codes without exotic tools or training.
Rock-solid warranty – 1-year full parts & labor on the whole unit, plus 5-year parts & labor on the sealed system.
When your mid-size rooms demand quiet, efficient cooling and heat-pump performance that just works, day in, day out, the Hotpoint AHHS12D3XXA is the workhorse that keeps paying off in five-star comfort and low maintenance costs.
