Criteria for Choosing the Best Pick

Performance

It’s worth mentioning from the onset that the best window air conditioner is the one that best meets your cooling needs, not the one with the highest BTU (British Thermal Units). With that in mind, BTU is indicative of the unit’s cooling capabilities vis-à-vis the size of the room. As a rule of thumb, a unit with a BTU rating of about 6,000 is ideal for rooms up to 250 square feet in size while an 8,000 BTU option is perfect for up to 350 sq. ft. and lastly, anything with an upwards of 12,000 is optimized for around 500 sq. ft. of space.

Additionally, keep in mind that models with higher CFMs (cubic feet per minute) provide quicker and more efficient performance than their weaker counterparts.

Efficiency

No one wants to be stuck with a window AC that consumes lots of electricity, and we bet neither do you. A value-conscious and logical consumer would, therefore, focus on acquiring a unit with the highest energy efficiency ratio (ERR) as it’s indicative of the unit’s energy consumption rate.

For most window ACs, the rating stands at 11.7, with the most efficient going up to 12. To get the most efficient, ensure your model is Energy Star certified, as this would mean it’s 20 to 30% more efficient than the threshold requirement.

Installation

You don’t require a science degree or working knowledge of physics to install a window-mounted air conditioner. The process typically should last a couple of minutes, even without assistance, depending of course on whether the model is lightweight and compact or not. Models with small profiles install in a snap, and with lots of ease.

Heavier ones, on the other hand, will require an extra pair of hands. Also, ensure your model has the right installation kit for a perfect fit on the window.

Ease of Use

The best window AC should be both powerful and easy to use. To this end, look for a unit that’s highly customizable to enable you better meet your cooling preferences. A model with several cooling modes, adjustable fan speeds, and diverse airflow pattern perform better. Other features you can consider as a programmable 24-hour on/off, remote control, and sleep and energy saver modes, among others.

Frequently Asked Questions

Q: Is a window-mounted conditioner better than a central air conditioning system.

A: In several ways, yes. A central conditioner is not only expensive and costly to run, they also hog lots of space. Window ACs, on the other hand, are inexpensive, efficient, and boasts small and lightweight profiles.

Q: How do I maintain one to ensure optimal performance?

A: Maintaining the units is quite a cinch and straightforward. Cleaning and replacing the air filter every once a while and cleaning the evaporator and condenser coils should do the trick.

Conclusion

A window-mounted air conditioner is a more efficient and cost-effective alternative to the central air conditioning. And our list features ten of the best models available on the market currently. They are powerful, quiet, efficient, reliable, easy to use, long-lasting, and budget-friendly.
