As someone who has struggled to find the perfect AC unit for my side opening windows, I understand the frustration and confusion that comes with this shopping process. However, after extensive research and personal experience, I have compiled a comprehensive buying guide to help you navigate through the different options and make an informed decision.

Understanding Your Window Type

Before you begin your search for an AC unit, it is important to understand the type of window you have. Side opening windows are also known as casement windows, which open outwards like a door. These windows are different from traditional double-hung or sliding windows, and therefore require specific types of AC units.

The size of your room and the BTU (British Thermal Units) capacity of the AC unit are crucial factors to consider when purchasing an AC unit for side opening windows. You can determine the appropriate BTU capacity by considering the square footage of your room. As a general rule, 5,000 BTUs are suitable for rooms up to 150 square feet, while larger rooms may require higher BTU capacities.

Energy Efficiency

An energy-efficient AC unit not only helps in reducing your electricity bills but also has a positive impact on the environment. Look for units with an Energy Star rating, which indicates that they meet strict energy efficiency guidelines set by the US Environmental Protection Agency.

Installation Requirements

Installing an AC unit in a side opening window can be tricky as it requires additional support brackets or panels to secure it in place. Some units come with these accessories included, while others may require separate purchase. Make sure to check if your chosen unit is compatible with your window type and if any additional installation equipment is needed.

Additional Features

Depending on your personal preferences and needs, there are various additional features that you may want to consider when purchasing an AC unit for side opening windows. These include remote control operation, programmable timers, multiple fan speeds, air purifying filters, and dehumidifying capabilities.

Noise Level

AC units can be noisy and disruptive, especially if they are placed in bedrooms or other quiet spaces. Look for units that have low noise levels or come with a sleep mode feature that reduces noise during nighttime operation.

Price Range

AC units for side opening windows come in various price ranges depending on their size, features, and brand. It is essential to set a budget before starting your search and stick to it to avoid overspending.

Conclusion

Finding the right AC unit for your side opening window may seem overwhelming at first but armed with this buying guide; I am confident that you will make an informed decision. Remember to consider factors such as size and BTU capacity, energy efficiency, installation requirements, additional features, noise level, and price range when making your purchase.
