With so many options available in the market, it can be challenging to know which one is the best for your needs. In this buying guide, I will be sharing my personal experience and tips to help you make an informed decision.

What is an Over The Sill Air Conditioner?

An over the sill air conditioner is a type of window air conditioner that is designed to be installed through a window sill rather than in the window itself. This allows for a more secure and stable installation as well as better energy efficiency.

Budget

Before starting your search, it’s essential to determine your budget. Over the sill air conditioners come in a wide range of prices, so knowing how much you are willing to spend will narrow down your options. Keep in mind that cheaper models may not have all the features and functions you desire.

Cooling Capacity

The cooling capacity of an over the sill air conditioner is measured in BTUs (British Thermal Units). It is important to consider the size of your room when choosing a cooling capacity. A higher BTU output will cool a larger area, while a lower output will work better for smaller rooms.

Energy Efficiency

Since air conditioners consume a significant amount of energy, it’s essential to consider their energy efficiency. Look for units with Energy Star ratings, as they are designed to use less energy while still providing optimal cooling performance.

Noise Level

Air conditioners can be noisy, especially if you plan on using them in your bedroom or living room. Look for models with lower decibel levels for a quieter operation.

Installation

Installing an over the sill air conditioner may require some DIY skills or professional help depending on your abilities and the model you choose. Make sure to read reviews or consult with an expert before making your purchase.

Maintenance

Regular maintenance is crucial for keeping your over the sill air conditioner running efficiently. Consider models with washable filters or easy access panels for cleaning and changing filters.
