Info & Guides

Description

Cooling the room you use most during a long heat wave can make your electric bill the first thing you check each month. The Whirlpool 12,000 BTU Inverter Window Air Conditioner keeps that number manageable, with an estimated yearly operating cost of 61 dollars. It mounts in a standard single- or double-hung window, and the mounting hardware comes in the box.

Key Features and Benefits of the Whirlpool 12,000 BTU Inverter Window Air Conditioner

  • 12,000 BTU Cooling: Delivers up to 265 CFM of airflow, so cool air reaches the far corners of a medium room.
  • Inverter Technology: The inverter-driven motor slows down instead of shutting off once your setpoint is reached, so your temperature stays steady and energy use stays low.
  • Energy Star Efficiency: An EER of 15 and Energy Star certification mean you get more cooling from each watt, with a maximum draw of 1,190 watts.
  • Quiet Mute Setting: Noise ranges from 42 dB on mute speed to 55 dB at maximum, so you can go quiet for sleep or full power on hot afternoons.
  • Operating Modes: Cool mode lowers the temperature and Dry mode pulls moisture from humid air, while Fan Only mode circulates air on milder days.
  • Eco and Sleep: Eco mode runs the compressor only as needed, while Sleep mode lowers fan speed and gradually raises the setpoint as nighttime temperatures fall.
  • 24-Hour Timer: You can set the timer to switch the air conditioner on or off on your schedule, so it runs only when you need it.
  • Remote and Panel: You can change settings from the electronic control panel or from the included full-function remote control without leaving your seat.
  • Fan Control: You get 3 fan speeds plus Auto Fan, which matches speed to cooling demand, while auto-swing louvers spread air across your room.
  • R-32 Refrigerant: It uses an environmentally friendly refrigerant and is rated for cooling from 61 to 90 degrees F, so you can check that range against your climate.
  • Washable Filter: The air filter behind the front intake grille traps airborne particles, and a Clean Filter reminder tells you when to vacuum or wash it.
  • Auto Restart: After a power outage, the air conditioner restarts on its own with your saved settings, so you come home to a cool room.

Check Your Window and Outlet Before Installing

This air conditioner fits single- or double-hung windows from 25 to 36 inches wide with an opening at least 14.5 inches tall, so measure your sash before you start. The chassis measures 19.25 x 20.67 x 13.39-Inches (L x W x H) and weighs 58.6 pounds. Factor that weight into how you lift it into the window.

It runs on 110 to 120 volts through a 5-15P plug on a cord 4.9 feet long, so the window you choose needs an outlet close by. Because it draws up to 10.3 amps on a circuit rated for 115 volts and 15 amps, it's best not to share that circuit with other high-draw appliances. The included kit supplies foam seal, brackets, lock frames, and hardware.

Sylvane's Expert Take

If you want window cooling that won't spike your electric bill, this Whirlpool suits the room you spend the most hours in, whether that's a home office by day or a bedroom at night. Dry mode helps on muggy days, and the inverter holds your setpoint steady. Keep in mind that it cools only, with no heat mode. The features that matter most are the inverter and the 42 dB mute setting, and together they make for calmer, cooler summer nights.
