The Ultimate Guide to Air Conditioners for Casement Windows: Everything You Need to Know

When it comes to keeping your home cool during the sweltering summer months, having an air conditioner is essential. However, not all homes are equipped with the traditional double-hung windows that accommodate standard window air conditioning units. Casement windows, which open outward with a crank or lever, present a unique challenge when it comes to finding the right air conditioner. But fear not, as this comprehensive guide will walk you through everything you need to know about air conditioners for casement windows.

What are Casement Windows?

Casement windows are a popular choice for many homeowners due to their unique design and functionality. They are hinged on one side and open outward, providing excellent ventilation and unobstructed views. Casement windows are often found in older homes, but they are also a popular choice for modern and contemporary designs.

The Challenge with Casement Windows and Air Conditioners

The main challenge when it comes to installing an air conditioner in a casement window is the window's design. Traditional window air conditioning units are designed to fit into double-hung windows, which slide up and down. Casement windows, on the other hand, open outward, making it difficult to install a standard air conditioner without obstructing the window's functionality.

The Solution: Casement Window Air Conditioners

Thankfully, there are air conditioners specifically designed for casement windows. These units are typically more compact and have a vertical orientation, allowing them to fit into the narrow space of a casement window. Casement window air conditioners are installed using a special bracket that supports the unit and allows the window to remain functional.

Choosing the Right Casement Window Air Conditioner

When shopping for a casement window air conditioner, there are several factors to consider:

1. Size: Measure the width and height of your casement window to ensure the air conditioner will fit properly. Most casement window air conditioners are designed to fit windows that are 15-16 inches wide and at least 21 inches high.

2. Cooling Capacity: Choose an air conditioner with the appropriate cooling capacity for your space. Cooling capacity is measured in British Thermal Units (BTUs) per hour, and the required BTUs will depend on the size of the room you're trying to cool. As a general rule, you'll need roughly 20 BTUs per square foot of living space.

3. Energy Efficiency: Look for an air conditioner with a high Energy Efficiency Ratio (EER) to save on energy costs. The EER is calculated by dividing the cooling capacity (in BTUs) by the power consumption (in watts). The higher the EER, the more energy-efficient the unit.

4. Additional Features: Consider any additional features that may be important to you, such as programmable timers, remote controls, or air filters.

Installation Tips for Casement Window Air Conditioners

Installing a casement window air conditioner can be a bit more involved than installing a standard window unit, but with the right tools and some patience, it's a manageable DIY project. Here are some tips to help ensure a smooth installation:

1. Read the Manufacturer's Instructions: Before beginning the installation process, carefully read the manufacturer's instructions for your specific air conditioner model.

2. Gather the Necessary Tools: You'll likely need a screwdriver, drill, level, tape measure, and possibly a saw or other cutting tool (depending on your window frame).

3. Install the Support Bracket: Follow the manufacturer's instructions to install the support bracket that comes with your casement window air conditioner. This bracket is crucial for ensuring the unit is properly supported and the window remains functional.

4. Seal Any Gaps: Once the air conditioner is installed, use foam insulation or weatherstripping to seal any gaps around the unit. This will help improve energy efficiency and prevent drafts.

5. Secure the Unit: Make sure the air conditioner is securely fastened to the support bracket and the window frame to prevent it from falling out of the window.

Maintaining Your Casement Window Air Conditioner

Proper maintenance is essential for ensuring the longevity and efficiency of your casement window air conditioner. Here are some basic maintenance tasks to keep your unit running smoothly:

1. Clean the Air Filter: Regularly clean or replace the air filter to ensure optimal airflow and prevent dust and allergens from circulating in your home.

2. Check the Condenser Coils: Inspect the condenser coils for dirt and debris, and clean them as necessary to maintain energy efficiency.

3. Inspect the Window Seal: Periodically check the seal around your air conditioner to ensure there are no gaps or drafts. Reapply weatherstripping or foam insulation as needed.

4. Schedule Professional Maintenance: Have your air conditioner professionally serviced every 1-2 years to ensure it's running at peak efficiency and to catch any potential issues before they become major problems.

In conclusion, while casement windows may present a unique challenge when it comes to installing an air conditioner, there are solutions available. By choosing the right casement window air conditioner, following the proper installation procedures, and keeping up with regular maintenance, you can enjoy a cool and comfortable home all summer long.

Why choose the tilt and turn opening method?

Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
