If you want Samsung's draft-free WindFree cooling in a large room and your winters get properly cold, this is the one. It's the biggest system in Samsung's cold-climate Max Heat line. It keeps heating down to -22F, and it still makes most of its heat on a 5F morning.

Two things to know. Despite the "24k" name, it's rated at 22,000 BTU for cooling. And its efficiency is ordinary for its size, so you're paying for the comfort feature and the cold rating rather than low running costs. A professional installs it.

Review methodology

Strengths

  • Keeps heating down to -22F, and still makes about three-quarters of its heat at 5F.
  • WindFree mode cools the room without blowing air straight at you.

Weaknesses

  • Rated at 22,000 BTU for cooling, not the 24,000 its name suggests. Size it on the real figure.
  • Ordinary efficiency for its size, so it costs more to run than the most efficient systems.
  • One unit is a lot to ask of a big space. A multi-zone system, or two smaller units, may heat it more evenly.

Frequently asked questions

Can I install the Samsung WindFree Max Heat 24,000 BTU R-32 208/230V (AR24DXDABWKN / AR24DXDACWKX) myself, or do I need a pro?
Samsung WindFree Max Heat 24,000 BTU R-32 208/230V (AR24DXDABWKN / AR24DXDACWKX) 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 Samsung WindFree Max Heat 24,000 BTU R-32 208/230V (AR24DXDABWKN / AR24DXDACWKX) keep heating in a cold winter?
The AHRI/ENERGY STAR certification lists 18,500 BTU/h of heating capacity at 5F. Rated heating operation extends down to -22 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 Samsung WindFree Max Heat 24,000 BTU R-32 208/230V (AR24DXDABWKN / AR24DXDACWKX) need?
Published electrical requirements: 230 V voltage, 21 A minimum circuit ampacity, and 30 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. The outdoor unit's factory charge covers up to 24.6 ft of line; longer runs need added refrigerant. Measure the planned routing before ordering.
What warranty does the Samsung WindFree Max Heat 24,000 BTU R-32 208/230V (AR24DXDABWKN / AR24DXDACWKX) carry?
The manufacturer publishes these warranty tiers: Registered: 10 yr parts / 10 yr compressor (eligible registered system). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
