What are the things to consider to get the right size of aircon you need?
The size of the air conditioner is an aspect of big concern because it will be determinant of the cooling capacity of your aircon. Here are the things you need to consider to get the right size of aircon that you need for your home or your room.
1. Consider the room size
The room size is one of the most important factors to determine the size of the air conditioner you need. You have to measure the size of the area of the room or household you want to cool and look for an air conditioner that has enough horsepower to keep that specific area cool. You can measure the area of the room by multiplying the length and the width of the room, as it is the area that needs to be cooled.
Calculating the room size can be hard, especially when your room is not a perfect square or rectangle. If it is the case, you can divide the room into separate sections to compute the precise area.
How much does air conditioning cost? Generally, air conditioning services cost around $600 to $6000, depending on the size of the air conditioner and the complexity of the job required to install it in your home.
2. Consider the room height
Another factor aligned to the room area is the room height. The room height is also an important determinant of how adequate is a specific cooling capacity. Just like the room area, it constitutes the size of the area that needs to be cooled. Rooms and areas with high ceilings significantly need a more powerful air conditioner because more air is circulating in the area than regular rooms with regular heights.
For rooms that are higher than the regular ones, wall-mounted mini-splits are advised than window-mounted air conditioners. It is because splits are mounted higher on the walls’ surface, which allows the warm air to rise.
3. Consider the humidity level
If your home has a high humidity level, it requires more cooling or high-powered cooling. An air conditioner is a dehumidifier as it blows the cool air in a certain area of your home. As the air conditioner removes the excess moisture in the air, it will create a difference in the temperature of the area, and it will add comfort to you and your loved ones.
Suppose you live in an area with high moisture content, consider investing in an air conditioner with an extra capacity.
4. Consider your location
Aside from observing humidity levels, you must observe your location in general. It is very important to be fully aware of your location, whether you reside in a generally hot or cold place. If you reside in low-altitude places, you must invest in high-powered air condition. If you reside in a mid lever altitude, regular air conditioning with mid-level capacity will do. Keep in mind that the location you reside in matters in the size and capacity of the aircon you need.
How much does an aircon cost per room size?
Suppose that you want an aircon installed in your home and you are thinking of the cost of air conditioner appropriated to different room sizes. Here is a rough guide of the cost per approximate area.

Why should you invest in a proper-sized air conditioner?
The size of an air conditioner matters in its capacity and efficiency. Here are the advantages of a proper-sized air conditioner in your home.
1. Cost Efficiency
A proper-sized conditioner will require fewer repairs and provide you with adequate cooling. Thus, you have more savings than buying a regular air conditioner without considering the size and capacity. The money you will spend on repairs and maintenance should be spent on measuring the area and choosing the strategic position of the aircon to cool your place efficiently.
Entrust the measuring and mounting job to a professional air conditioning service. Ask for free aircon installation quotes and get the best deal in your area. In this way, you no longer need to worry about the measurement of the area and the installation of your air conditioner.
2. Energy efficiency
There will be high energy efficiency when you have a proper-sized air conditioner in your home. The proper-sized air conditioner takes just a little time to cool a place that is exact at its capacity. While if you have a smaller one, it may take a long while to cool an area, which means a bigger energy bill. On the other hand, if you buy a bigger air conditioner whose capacity is beyond the area that needs to be cooled, it will also result in a bigger energy bill.
Thus, by buying the right size of air conditioner that is enough to cool a specific area, you no longer need to think of getting less or more energy to get the adequate cooling that you need.
