Who This Is For

This review is suited for persons wanting to learn, purchase, use, or sell window air conditioners by informing them of the best conditioners and giving relevant advice.

What is a window air conditioner?
An air conditioner can be described as a device that helps to maintain the temperature of indoor air at a certain level. When designed to be fitted at a window, it becomes a window air conditioner.

Besides temperature, the window air conditioner may also control the purity and humidity of the air in the indoor space it is operated in. The air conditioner is a must-have product if you face extreme and fatal temperatures.
What is BTU and why is it important to consider when buying an air conditioner?
BTU stands for British Thermal Unit. Unlike what its name suggests it is commonly used in the US as one of its Imperial measurement units.

This measurement describes the amount of energy that is used by an air conditioner – in this case, a window air conditioner – to have heat removed from indoors within one hour. Since the higher the BTU the faster an air conditioner can remove heat or add it, it is an important consideration when buying an air conditioner.
Does size matter when wanting to cool a larger room?
Some experts mention that size matters when it comes to cooling a room. However, since cooling is only a reduction in temperature, the size issue becomes insignificant.

To get the right window air conditioner:
Compute the floor area to be served by the window air conditioner in feet squared.
Take the result of the floor area in feet squared and multiply it by 25 BTU/feet squared.
Choose window air conditioners that would operate around the BTU required to cool a room as obtained.

Since larger rooms have more floor areas, the BTU required will be higher. If the room would obtain all the cooling from a single window air conditioner, it would be probable that the size of the window air conditioner would be greater.

Why You Should Trust Us

Some window air conditioners in the market don’t please clients due to poor indoor temperature control. This review helps to avoid such brands by suggesting tested and tried window air conditioners that would control the temperature of indoor spaces efficiently.

How We Picked

Online marketplaces reveal a large number of brands that market window air conditioners hence making it difficult to choose one. So, we opted to make the search process for the right window air conditioner easier by using past user experience to provide insight into the process. Some of the things that the consumer said had occurred to them while using the window air conditioners include: a window air conditioner not meeting the minimum specifications as mentioned by the manufacturer, encountering tricky Wi-Fi connections, and having their indoor noise polluted. We believe with the sentimental analysis done on such opinions, you will trust our review to guide you in buying the best window air conditioner.

During the product testing, analysis, and research reporting we looked into the factors of size, weight, noise, range, and reach. Besides that, we computed the relevant metrics depicting each product’s portability, cooling options, airspeed, noise, ventilation, installation, durability, energy efficiency, and air quality. Since we would like you to save money, we searched for options that favored many in respect of quality per unit price and cost of operation.

Size
We ensured that the size stated by the manufacturer reflected the real product’s size. The size was evaluated according to the wall thickness and window width efficient cooling.

Weight
Since window air conditioners are the lightest air conditioners available, weight was a factor that fascinated the users of window air conditioners. The low weight that favored portability was seen as a positive attribute although there was a trade-off between the suitability of the weight and the level of the desired BTU.

Portability
Some of the factors that affect portability that we focused on include size, weight, and ergonomics. This aspect was ascertained in products that the manufacturers had identified as portable and were ranked by user preference.

Cooling Options
Most window air conditioners have cooling options which founded our cause of using it as an evaluation factor. The options of medium, high, and low are frequently observed which we in turn looked for. Customer feedback helped to back our decisions of the best window air conditioners based on this factor.

Air Speed
We understand that sometimes the airspeed of a window air conditioner may get uncontrollable. The ability to adjust the airspeed was investigated to inform us of the best product.

Noise
It is known that noise pollution is a crime and a vice that leads to poor health and stress among the persons that encounter these ill conditions. Therefore, we saw the need to investigate the sound levels of the operations of these window air conditioners. Generally, less noise was translated as a strength in the respective product.

Easy to Install
Installation assistance was sought when trying to install through manuals and installation kits in the latest design to pick out the best. This attribute helped to provide information on how the clients were and will experience when installing window air conditioners.

Price vs Quality
Quality-price ratio helped to inform us of the products that offered the highest level of quality per unit price, which is an acquisition cost of the window air conditioner. The higher the quality-price ratio the better the product was.

Durability
The longer a window air conditioner serves a person before it is replaced the better it is and the higher it is ranked by consumers. This factor helped to vote for the best window air conditioner and promote quality products.

Ventilation
The window air conditioner has the task of controlling the level of temperature in a room, its ventilation capabilities have to be tested. Measures used to ensure good circulation of air by the conditioners were compared across the products and evaluated to select the best.

Energy efficiency
We ensured that products labeled as energy efficient had relevant certifications that backed up their assertions such as Energy Star. This helped us to prevent products that are sustainable and may help the consumer in achieving targeted savings in electricity utility payments.

Range/Reach
The range and reach of window air conditioners vary according to the floor area and the height of the room. Since manufacturers design the air conditioners to serve a certain minimum floor area, such assertions were confirmed to pick out quality products. Also, the inadequacy to cool a room that may be attributed to a room’s high height was looked out for to ensure the customer had the right product.

Air Quality
Tiny substances such as pollen and dust reduce the quality of air if they suspend in the air that is breathed by human beings. In response to this, we ensured that we could locate window air conditioners that contain filters. The presence of a filter implied that the product was a good promoter of excellent air quality.
