Window AC Buying Guide

By taking all these factors into account, you can be sure to choose the best possible window air conditioner for your needs. With a little research, you should be able to find an AC unit that will keep you cool and comfortable all summer long.

Things to Consider Before Buying Tower AC

Cooling capacity

The cooling capacity of a window air conditioner is the amount of heat it can remove from the air in an hour. It is typically measured in British Thermal Units (BTUs). The higher the BTUs, the more powerful the AC unit will be. The number of BTUs you need will depend on the size of the room you want to cool and your climate. To determine how many BTUs you need, you can use an online BTU calculator or ask a professional.

For example, if you live in a hot and humid climate, you will need a higher number of BTUs to cool your home than someone who lives in a cooler climate. Additionally, if you have a large room that you want to cool, you will need more BTUs than someone with a smaller room. Most window AC units range from 5,000 to 12,000 BTUs. Therefore, it is important to choose the right size unit for your needs in order to ensure optimal cooling power.

Room Size

The size of the room is an important factor to consider when choosing the best 1.5 ton window AC. You’ll want to choose an AC unit that is powerful enough to cool the entire space, but not so powerful that it wastes energy. A good rule of thumb is to choose an air conditioner that has a cooling capacity of at least 20 BTUs per square foot of living space. So, for a 150-square-foot room, you should look for an AC unit with a cooling capacity of at least 3,000 BTUs. Read this article on how to calculate room size for AC to know more.

Another factor to keep in mind is the size of the window opening. Make sure to measure the width and height of the window opening before choosing an AC unit, as you’ll need to make sure the unit will fit in the opening. Lastly, keep in mind that you’ll need to have access to an electrical outlet in order to use a window air conditioner. If you don’t have an electrical outlet near your window, you may need to use an extension cord, which can be a fire hazard. Therefore, it’s important to carefully consider all these factors before choosing a window air conditioner for your home.

Power Consumption

In India, during the summer season, it is very hot. You can’t live without an air conditioner whether its daytime or nighttime. That means your AC would be on for a minimum of 6-7 hours a day. This kind of usage impacts electricity bill. Looking into this need and to reduce the power consumption, the air conditioner manufacturers have come up with energy-saving technology. As per the power consumption capacity, ACs get a power rating by the Bureau of Energy Efficiency (BEE). The more ISEER rating AC has, the less electricity it consumes and vice-versa. For example, a 5-star AC will consume less electricity as compared to a 1-star AC. Read this article on what is star rating in AC to know more.

Voltage (V), current (I), and frequency (Hz) are important factors that contribute to the energy efficiency of an AC. Inverter ACs are more energy efficient as compared to non-inverter ACs because they consume less electricity. Various other factors such as ISEER value and cooling capacity also help in determining the energy efficiency of an AC. When buying an AC make sure to check for all these factors so that you can save on your electricity bills.


The climate is the average weather condition in a place over a long period of time. It’s determined by factors like average temperature, humidity, rainfall, and wind patterns. Climate can also affect things like what kind of plants can grow in an area. Different types of air conditioners are better suited for different climates.

For example, if you live in an area with mild summers, you might be able to get away with a smaller and less powerful AC unit. However, if you live in a hot and humid climate, you’ll need to choose a larger and more powerful unit preferably with a dry mode. AC units come in all sorts of shapes and sizes, so it’s important to choose the one that’s right for your climate.

Noise level

When it comes to choosing a window air conditioner, there are a number of factors to take into account.

Air Flow

Air flow is a crucial element of any window air conditioner. It is responsible for moving the air that is cooled by the unit and circulating it throughout the room. The air flow is measured in cubic feet per minute (CFM), and the higher the CFM, the more air will be moved and the faster the room will cool down. There are a few factors that can affect the air flow of a window air conditioner, such as the size of the unit, the speed of the blower, and the direction of the airflow.

If the unit is too small for the room, it will not be able to move enough air to cool down the space effectively. The blower speed also plays a role in how much air is moved; a higher speed will result in more airflow. Lastly, the direction of airflow can impact how well the cool air is distributed; for example, an upward airflow will cause the cool air to rise to the ceiling while a downward airflow will direct the cool air towards people in the room. By understanding how these factors affect air flow, you can ensure that your window air conditioner is operating at peak efficiency.

Condenser Tubes

Copper is an excellent conductor of heat and electricity, which makes it ideal for use in air conditioners. Copper condenser tubes can transfer heat more efficiently than other materials, such as aluminum. Additionally, copper is more durable than aluminum and less likely to corrode over time.
