When it comes to choosing the best casement window air conditioner for your home, there are several factors you should consider. Here are the top factors to keep in mind:

  1. Cooling Power/Area Coverage: Look for an air conditioner with sufficient BTU capacity to cool your room effectively. Consider factors such as room size, sunlight exposure, and additional heat sources.

  2. Size: Ensure that the air conditioner fits your window dimensions. Measure your window accurately to find a unit that matches the size requirements.

  3. Weight: Consider the weight of the unit and ensure that your window and wall can support it safely.

  4. Location: Determine if you will install the unit from the inside or outside. Depending on the height and accessibility of your window, you may need assistance during installation.

  5. Filtration Challenges: Check the quality and availability of replacement filters. Opt for units with washable or reusable filters to reduce maintenance costs.

  6. Methods of Operation: Choose a unit with modern controls and user-friendly features for easy operation. Features like remote control and programmable timers add convenience.

  7. Energy Efficiency Ratings: Look for units with high EER ratings for energy efficiency and lower operating costs.

Casement Window Air Conditioner Installation

Installing a casement window air conditioner can be done as a DIY project or with the help of a professional. Here is a step-by-step guide to help you with the installation process:

  1. Install the Platform and the Support Base:

    • Create a strong support base using two wooden boards. One board should be slightly longer than the unit's width, while the other should match the length of the window's bottom track.
    • Attach the platform assembly to the support base using screws.
  2. Determine the Center Hole:

    • Measure the window's outermost edge to find the center point. Use a drywall T-square for accuracy.
    • Drill a hole at the center point for the assembly screw.
  3. Fix the Adjustment Platform:

    • Install the platform assembly from the outside using screws.
    • Secure the support base using high-grade plywood for added strength.
  4. Position the Unit on the Window:

    • Carefully lift the unit and place it on the platform assembly.
    • Close the vertical window sash against the unit's left side.
  5. Achieve a Backward Tilt:

    • Ensure that the unit has a slight backward tilt to allow for proper drainage of moisture.
    • Adjust the unit's position to achieve the desired tilt.
  6. Seal the Window Unit:

    • Seal the gap left at the top of the window with acrylic sheeting or a plastic board.
    • Ensure that the seal is secure to prevent air leakage.

Please note that these instructions are general guidelines and may vary depending on the specific unit and window type. Always refer to the manufacturer's instructions for detailed installation steps.

By considering the factors mentioned in this buying guide and following the installation instructions carefully, you can find the right unit for your home and enjoy efficient and comfortable cooling all summer long.
