Cooling Capacity (BTUs)
This unit has been a lifesaver during the summer, making my bedroom comfortably cool even in extreme heat.
Noise Level
Remarkably quiet operation – it makes less noise than a pedestal fan, and I can barely hear it when watching videos.
Installation and Size
Easy to install, even in an upper sash window, thanks to its lightweight design.
Additional Features
Perfect for a small room – the cooling output is excellent and the long cord is a handy feature.

The Frigidaire FHWC063TC1 Window Air Conditioner offers a cooling capacity of 6,000 BTUs, making it suitable for rooms up to 250 square feet. This makes it a solid option for smaller spaces like bedrooms or home offices. Its Energy Efficiency Ratio (EER) is 11, which isn't the highest but is reasonable for its size. However, it does not have an Energy Star rating, which could be a drawback if energy efficiency is a top priority for you.

The unit operates at a noise level of 51 dB, which is relatively quiet, thus it won't be overly disruptive during its operation. Installation is made easier with the included window kit, and its compact dimensions (15.9 x 13.2 x 12 inches) ensure it fits well in most windows without being too bulky. The multi-speed fan offers flexibility in cooling, allowing you to choose from three different speeds. Additionally, it features a remote control, a filter light reminder, and a washable dust filter, adding convenience and ease of maintenance.

However, it lacks some advanced features like Wi-Fi connectivity which might be appealing for users looking for more smart-home integration. The 1-year manufacturer warranty provides a decent assurance of its durability. While not the most energy-efficient model on the market, its blend of practical features and user-friendly design makes it a worthwhile consideration for those in need of a straightforward and effective cooling solution.

Buying Guide for the Best Windows Ac Units

Choosing the right window air conditioning unit can make a significant difference in your comfort during hot weather. The key is to find a unit that fits your specific needs, taking into account the size of the space you want to cool, energy efficiency, noise levels, and additional features that can enhance your experience. By understanding the key specifications, you can make an informed decision and select a unit that will keep you cool and comfortable.
Cooling Capacity (BTUs)Cooling capacity, measured in British Thermal Units (BTUs), indicates how much heat the unit can remove from a room per hour. This is crucial because a unit with too low a BTU rating won't effectively cool the space, while one with too high a rating will cool the room too quickly without removing enough humidity, leading to a clammy feeling. To navigate this, consider the size of the room: for a small room (100-300 sq. ft.), 5,000-7,000 BTUs is sufficient; for a medium room (300-500 sq. ft.), 8,000-12,000 BTUs is ideal; and for a large room (500-800 sq. ft.), 14,000-18,000 BTUs may be necessary. Match the BTU rating to your room size for optimal comfort.
Energy Efficiency Ratio (EER)The Energy Efficiency Ratio (EER) measures the unit's cooling efficiency, calculated by dividing the BTUs by the power consumption in watts. A higher EER means the unit is more energy-efficient, which is important for reducing electricity bills and environmental impact. EER ratings typically range from 8 to 12. For the best efficiency, look for units with an EER of 10 or higher. If you use the AC frequently, investing in a higher EER unit can lead to significant savings over time.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the unit will be when operating. This is important for maintaining a comfortable and quiet environment, especially in bedrooms or living areas. Noise levels for window AC units typically range from 50 to 70 dB. For a quieter experience, look for units with noise levels below 60 dB. Consider where you will place the unit and how sensitive you are to noise when making your choice.
Installation and SizeThe size and weight of the unit affect how easy it is to install and whether it will fit in your window. This is important to ensure a secure and proper fit, which impacts the unit's efficiency and safety. Measure your window dimensions and compare them to the unit's specifications. Smaller units are easier to install and handle, while larger units may require additional support or professional installation. Choose a unit that fits your window and can be installed securely.
Additional FeaturesAdditional features can enhance the functionality and convenience of the unit. Common features include remote controls, programmable timers, sleep modes, and energy-saving settings. These features are important for customizing your cooling experience and improving energy efficiency. Consider which features are most important to you: a remote control for convenience, a timer for scheduling, or energy-saving modes to reduce costs. Select a unit with features that match your lifestyle and preferences.
