Why I Prefer a Window AC Unit for My Crank Window

As someone who has lived in an apartment with crank windows, I understand the struggle of finding the perfect air conditioning unit. After trying various options, I have come to the conclusion that a window AC unit is the best choice for my crank window. Here are some reasons why:

1. Easy installation: Unlike portable or split AC units, a window AC unit can easily be installed in a crank window without any complicated installation process. This saves time and effort, especially for renters who are not allowed to make major changes to their living space.

2. Space-saving: Living in a small apartment means every inch of space counts. A window AC unit takes up minimal space compared to other types of AC units, leaving more room for other belongings.

3. Efficient cooling: The placement of a window AC unit in a crank window allows it to draw fresh air from outside and cool it down before circulating it inside the room. This results in efficient cooling and better circulation of air compared to portable AC units that only recirculate indoor air.

4. Cost-effective: Window AC units are generally more affordable than other types of AC units, making them an ideal choice for those on a budget. Moreover

My Buying Guide on ‘Window AC Unit for Crank Window’

As someone who has recently gone through the process of purchasing a window AC unit for a crank window, I understand the challenges and considerations that come with this particular type of installation. In this buying guide, I will share my personal experience and provide tips to help you make the best decision when choosing a window AC unit for your crank window.

Understanding Crank Windows and Their Limitations

Before diving into the specifics of purchasing a window AC unit for a crank window, it’s important to understand the limitations of this type of window. Unlike traditional sliding windows, crank windows open outwards from the bottom and have a hinge at the top. This design makes it difficult to install a standard AC unit as it needs to be secured in place and may not fit properly.

Measure Your Window Opening

The first step in purchasing an AC unit for your crank window is to measure the opening. Measure both the height and width, as well as the depth from the inside of your home to where the bottom of the window meets the ledge. This will help you determine what size AC unit you need and if there are any size restrictions.

Consider BTU Output

BTU (British Thermal Units) is used to measure how much cooling power an AC unit has. The higher the BTU, the larger area it can cool. For crank windows, it’s recommended to choose an AC unit with at least 5,000-6,000 BTUs. However, if you live in a particularly hot climate or have larger windows, you may want to opt for a higher BTU output.

Choose Between Portable or Window-Mounted Unit

There are two types of AC units that are suitable for crank windows – portable and window-mounted units. Portable units do not require installation but do take up floor space and need to be vented through a nearby window or door. On the other hand, window-mounted units are designed specifically for this type of installation but can be more challenging to install.

Look for Specific Features

When shopping for an AC unit for your crank window, there are some features that you should keep in mind:

– Adjustable air direction: Look for units that allow you to adjust airflow direction so that cold air is directed towards where you need it most.
– Energy efficiency: Look for units with an Energy Star rating as they consume less energy and can save you money on your electricity bill.
– Remote control: Some units come with remote controls which can be convenient when adjusting temperature or settings from across the room.
– Noise level: If noise is a concern for you, look for units with lower decibel levels.

Budget Considerations

AC units can vary greatly in price depending on their features and BTU output. It’s important to set a budget before starting your search so that you don’t overspend or settle on something that doesn’t meet your needs.

Consult with Professionals

If you’re unsure about which type or size of AC unit would be best for your specific situation, it’s always best to consult with professionals such as HVAC technicians or sales associates at home appliance stores. They can offer their expertise and guide you towards making an informed decision.

In conclusion,, purchasing an AC unit for a crank window may require some additional considerations compared to traditional installations. By keeping these tips in mind and doing thorough research before making your purchase, you can find an efficient and suitable option that will keep your home cool during those hot summer months.
