Info & Guides

Description

A window AC that comes out every fall leaves you with an empty window and a seasonal chore. The Whirlpool 12,000 BTU Through-the-Wall AC stays in an exterior wall year after year, so your window stays clear. The included wall trim kit and rear grille finish the installation cleanly inside and out.

Key Features and Benefits of the Whirlpool 12,000 BTU Through-the-Wall AC

  • Cooling Power: Delivers 12,000 BTU and up to 282 CFM of airflow, giving you enough capacity for a medium room of up to 550 square feet.
  • Dry Mode: Removes up to 1.6 pints of moisture per hour, so humid afternoons feel more comfortable without you having to turn the room into a refrigerator.
  • ECO and Sleep: ECO mode cycles the compressor while the fan keeps circulating cool air, and Sleep mode gradually adjusts temperature and fan speed overnight to save energy.
  • Efficient Operation: An EER of 10 and a 1,060-watt maximum draw add up to an estimated $114 yearly operating cost, which makes your summer cooling bills easier to predict.
  • Flexible Controls: Set the programmable thermostat anywhere from 62 to 86 degrees F with the electronic touch controls or the included full-function remote.
  • 24-Hour Timer: The programmable timer switches the AC on or off on your schedule, so the room is already cool when you get home.
  • Directional Airflow: A pair of louver sets gives you 8-way directional control, so you can spread air evenly or aim it straight at your seat.
  • Fan Speeds: Pick from 3 fan speeds yourself, or let Auto mode choose the operating mode and fan speed based on room temperature.
  • Noise Levels: Runs at 56 dB on low and 60 dB on high, so you can choose quieter airflow for evenings and full power for hot afternoons.
  • Safety Certification: The R-32 refrigerant system carries UL certification, so you get a certified cooling system for permanent installation.
  • Auto Restart: Auto Restart saves your settings through a power failure and resumes operation when power returns, so you don't have to reprogram the thermostat.

Plan Your Wall Opening and Circuit Before Installation

The air conditioner measures 20.2 x 24.2 x 14.5-Inches (L x W x H) and weighs 69.6 pounds, so confirm your wall opening and have a helper ready before you lift it into place. At full cooling it draws up to 11.5 amps, which is why Whirlpool specifies a 115-volt, 15-amp circuit, and keeping other heavy loads off that breaker helps you avoid tripping it. The power cord is 4.9 feet long, so the outlet needs to sit close to the opening. Its 5-15P plug fits a standard 3-prong household outlet, which means you don't need to run a dedicated high-voltage line.

Sylvane's Expert Take

If you want permanent cooling for a bedroom, home office, or den of up to 550 square feet without giving up a window, this Whirlpool AC suits you well. This model cools only and has no heat mode, so you'll still need a separate heat source in winter. Dry mode and the 24-hour timer are the 2 features that matter most, and together they make this a smart permanent fix for sticky summers.
