The Ultimate Guide to Crank Casement Window Air Conditioners

As the summer heat approaches, it's time to start thinking about how to keep your home cool and comfortable. One popular option is the crank casement window air conditioner. This versatile and energy-efficient appliance can be a game-changer for those with casement windows. In this comprehensive guide, we'll cover everything you need to know about these unique air conditioners, from choosing the right model to installation tips and maintenance advice. Let's dive in!

What is a Crank Casement Window Air Conditioner?

A crank casement window air conditioner, also known as a vertical window air conditioner, is specifically designed for casement or sliding windows. These windows open by cranking a handle or sliding horizontally, making it difficult to install a traditional window air conditioner. Crank casement window air conditioners are designed with a vertical orientation, allowing them to fit snugly within the window frame.

Benefits of Crank Casement Window Air Conditioners

There are several advantages to using a crank casement window air conditioner, including:

1. Space-saving design: Their vertical orientation allows them to fit in windows where traditional window air conditioners wouldn't work, making them perfect for small apartments or homes with limited space.

2. Energy efficiency: Crank casement window air conditioners often have higher energy efficiency ratings than their traditional counterparts, which can save you money on your energy bills.

3. Easy installation: These air conditioners are relatively easy to install, especially if you have some DIY experience.

4. Versatility: They can be used in a variety of window types, making them a flexible option for those with unique window configurations.

Choosing the Right Crank Casement Window Air Conditioner

When selecting a crank casement window air conditioner, there are several factors to consider:

1. Size: Measure the width and height of your window opening to ensure the air conditioner will fit. Most models are designed to fit windows with a minimum width of 15 inches and a minimum height of 21 inches.

2. Cooling capacity: Choose an air conditioner with the appropriate cooling capacity (measured in BTUs) for your space. As a general rule, you'll need 20 BTUs per square foot of living space.

3. Energy efficiency: Look for a model with a high Energy Efficiency Ratio (EER) to ensure you're getting the most cooling power for your energy dollar.

4. Noise level: Some models are quieter than others, so consider the noise level if you'll be using the air conditioner in a bedroom or other quiet space.

5. Additional features: Some crank casement window air conditioners come with additional features like remote controls, programmable timers, and air filters. Consider which features are most important to you when making your selection.

Installing Your Crank Casement Window Air Conditioner

Once you've chosen the perfect air conditioner for your space, it's time to install it. Follow these general steps for a successful installation:

1. Gather your tools: You'll need a screwdriver, measuring tape, level, and potentially a drill and brackets (depending on your specific model).

2. Prepare the window: Open the window and remove the screen, if necessary. Clean the window frame and sill to ensure a secure fit.

3. Attach the brackets: Some models come with brackets to help secure the air conditioner in the window. Follow the manufacturer's instructions to attach these brackets to the window frame.

4. Install the air conditioner: Carefully lift the air conditioner into the window opening, making sure it's level and secure. Extend the side panels to fill any gaps between the air conditioner and the window frame.

5. Secure the air conditioner: Use the provided screws to secure the air conditioner to the window frame and brackets, if applicable.

6. Seal any gaps: Use weatherstripping or foam insulation to seal any gaps between the air conditioner and the window frame, preventing drafts and improving efficiency.

Maintaining Your Crank Casement Window Air Conditioner

Proper maintenance will ensure your air conditioner runs efficiently and lasts as long as possible. Follow these general maintenance tips:

1. Clean the filter: Most models have a removable filter that should be cleaned at least once a month during the cooling season. Simply remove the filter, wash it with warm soapy water, and let it dry completely before reinstalling it.

2. Inspect the fins: Check the condenser and evaporator fins for damage or bending, which can reduce airflow and efficiency. Use a fin comb to straighten any bent fins.

3. Clean the coils: Dust and dirt can accumulate on the evaporator and condenser coils, reducing efficiency. Use a soft brush or vacuum cleaner to gently clean the coils.

4. Check for proper drainage: Make sure the air conditioner is draining properly to avoid water damage or mold growth. If necessary, adjust the angle of the air conditioner in the window to improve drainage.

By following this comprehensive guide, you'll be well-equipped to choose, install, and maintain a crank casement window air conditioner that keeps your home cool and comfortable all summer long. Enjoy the refreshing relief from the heat, and rest easy knowing you've made a smart, energy-efficient choice.

INSPIRATION & SOLUTION

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.

Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.

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.
