Yes, it is generally recommended to tilt a window air conditioner slightly when installing it. Tilting the unit helps ensure proper drainage of condensate water that accumulates during the cooling process. The correct tilt allows the water to flow to the back of the air conditioner and drain outside.
Here's how to do it:
Identify the Correct Direction: Most window air conditioners are designed to be installed with a slight backward tilt. This means the back of the unit should be positioned slightly lower than the front.
Level the Window Opening: Before installing the AC unit, make sure the window opening is level and free from any obstructions.
Adjust the Side Panels: Most window AC units come with adjustable side panels or accordion-style extensions. Adjust these panels to fit snugly into the window opening to prevent air leakage.
Tilt the Unit Backward: As you slide the air conditioner into the window opening, ensure that the back of the unit is tilted downward. This can be achieved by placing shims or wooden blocks under the unit's outer edge at the back until it is at the correct tilt.
Secure the Unit: Once the air conditioner is in place and properly tilted, secure it to the window frame according to the manufacturer's instructions. This usually involves using screws or brackets to hold the unit in position.
Check for Proper Drainage: After installation, turn on the air conditioner and monitor the condensate drainage. The water should drip from the back of the unit and not accumulate inside the window or flow inside the room.
Tilting the window air conditioner is essential because it ensures that the condensate water does not seep into your home, potentially causing damage to your window sill, wall, or floor. Proper drainage also helps the AC unit operate more efficiently and prevents the build-up of mold and mildew within the unit. If you're unsure about the installation process or want to be extra cautious, consult the manufacturer's installation guidelines or seek the assistance of a professional.
