Sunpentown WA-1211S

Sunpentown (SPT) has now been on the market for almost 20 years. In that time they have managed to build a reputation in the air conditioning market that’s second to none, and the WA-1211S is probably their best unit to date. Designed to be installed in a window, it will cool the air in a room up to 500 square feet with a cooling capacity of 12,000 BTU. Unlike many other models in this range, the WA-1211S comes with numerous additional features.

Review Details

The WA-1211S is designed to fit windows that are at least 23 inches wide and no larger than 36 inches, however, it can be installed in vertical windows that are just 15.5 inches in width. It comes complete with everything needed for installation – all that’s needed from the consumer is a screwdriver.

SPT have not only made sure this air conditioner is Energy Star Rated, they have gone one step further with energy efficiency by installing an energy saving feature. This option is perfect for days when you’re away from the home. It can be pre-set to a desired temperature and the compressor will only run when that temperature is exceeded. It’s also worth noting this unit has an EER of 10.8.

What We Liked

  • Remote Control with Numerous Options
    The many options of the WA-1211S can be operated using the remote control. This includes the fan setting – fan only when it’s chilly outside, with 4 speeds. Cool mode – lowers the temperature to a minimum of 62 degrees Fahrenheit. Dry – Acts as a dehumidifier. Auto – Automatically maintains the desired temperature.
  • 24 Hour Timer
    The programmable timer allows you to set the A/C to auto start or shut-down in increments of 30 minutes for up to 10 hours or, if preferred in increments of 1 hour up to 24 hours.
  • Digital Display
    The WA-1211S comes with soft-touch controls. It has indicator lights for each fan/mode and display screen for timer and temperature settings.
  • Sleep Mode
    Perfect for the bedroom, the WA-1211S comes with a sleep mode/timer which makes for a comfortable temperature whilst sleeping.

What We Didn't Like

  • Weight
    The Sunpentown WA-1211S is quite weighty, so be prepared upon installation. However, due to the robustness of this air conditioner, there was little SPT could do about it.
  • Noise
    Noise can be an issue, however, it has been noted that consumers who complain about this are not using the auto/sleep mode.


The SPT WA-1211S is an air conditioning unit that has been designed to not only effectively cool the air in a 500 square foot space; it has also been designed with ease of use in mind. Its aesthetically pleasing and the included remote control has many features other manufacturers cannot boast in the 12,000 BTU range. SPT have also gone one step further with the Energy Star Rating by including an energy saving feature. At approximately $300, this A/C is an excellent buy.
