My Buying Guide on ‘Best Over The Sill Air Conditioner’

As someone who has gone through the process of buying an over the sill air conditioner, I understand how overwhelming it can be to choose the best one for your needs. There are many factors to consider, such as size, cooling capacity, energy efficiency, and price. In this buying guide, I will share my personal experience and provide you with all the necessary information to help you make an informed decision.

Size and Cooling Capacity

The first thing you need to consider when buying an over the sill air conditioner is the size of your room. The cooling capacity of an air conditioner is measured in British Thermal Units (BTUs) per hour. The higher the BTUs, the larger area it can cool effectively. For example, a 5,000 BTU unit is suitable for a room size of 100-150 square feet, while a 10,000 BTU unit can cool a room up to 450 square feet.

It is important to match the BTU capacity with your room size to ensure efficient cooling. An undersized unit will have to work harder and consume more energy to cool the room, while an oversized unit will cycle on and off frequently and not dehumidify properly.

Energy Efficiency

In today’s world where energy conservation is crucial, it is essential to consider the energy efficiency of an over the sill air conditioner before making a purchase. Look for units with ENERGY STAR certification as they meet strict energy efficiency guidelines set by the U.S Environmental Protection Agency (EPA). These units consume less energy and save you money on your electricity bill.

You can also look for additional features like programmable thermostats and energy-saving modes that help reduce energy consumption.

Installation

Installing an over the sill air conditioner is relatively easy compared to other types of AC units. However, it is essential to measure your window opening before purchasing one. Most units come with installation kits that include brackets and weather seals for a secure fit. Make sure to follow the manufacturer’s instructions carefully for proper installation.

Noise Level

If you are sensitive to noise or want a peaceful environment in your home or office, consider looking for units with low noise levels. Generally, air conditioners with lower BTUs tend to be quieter than higher BTU units.

Price

The price of an over-the-sill air conditioner varies depending on its size and features. It is always wise to set a budget beforehand and stick to it while considering all other factors mentioned above.

Maintenance

Maintenance plays a crucial role in keeping your over-the-sill air conditioner running efficiently. Make sure to clean or replace filters regularly as clogged filters can reduce efficiency and increase energy consumption.

You should also check for warranties offered by different brands before making a purchase. A longer warranty period indicates that the manufacturer has confidence in their product’s quality.

Conclusion

In conclusion, when looking for the best over-the-sill air conditioner, consider factors such as size, cooling capacity, energy efficiency, noise level, price, installation process and maintenance requirements. It is always recommended to do thorough research on different brands and read customer reviews before making a decision. With this buying guide and some careful consideration, you can find the perfect over-the-sill air conditioner that meets your needs within your budget.
