Split air conditioners are becoming an indispensable choice in the progressively hotter weather, especially as they have the added benefit of being energy efficient and highly effective. However, people are always hesitant to choose between different sizes and powers of air conditioners. In this article we will give you some reference advice so that you can choose the right mini-split air conditioner for you more quickly.

What dose BTUs mean for you and your mini-split ac?

When you are shopping for a split air conditioner, chances are you’ll come across the acronym BTU. What does this really mean?

BTU stands for British Thermal Unit, a unit of measurement that shows how much energy your air conditioner consumes from your home in one hour. It may seem overly technical, but for split air conditioners, BTU is an important indicator that can help you determine what kind of air conditioner you need for the size of your home.If you buy a split air conditioner without paying attention to its BTU rating, this could potentially have a serious impact on your comfort level. If you see that your air conditioner has 12,000 BTUs, this means that it absorbs 12,000 BTUs of heat per hour and transfers it outside so that your indoor environment will feel better.

So, what kind of BTUs should you choose? 

What are the factors that influence BTUs?

Experimental data shows that the most important factor affecting the BTUs of split air conditioners is the size of the room.  

Generally speaking, an air conditioner requires about 20 BTUs for every square foot of living space it cools. to get a rough idea of how many BTUs you need, multiply the square footage of your room by 20.

For example, let’s say you need to find a split air conditioner large enough to cool your 1,200 square foot home. You should look for a unit with about 24,000 BTUs. But always remember to keep in mind that this is a simple, general estimate and does not apply to all situations. A true BTU calculation will take into account your ceiling height and the size of your windows and doors. You can ask an experienced air conditioning installation technician for advice on how to calculate BTUs.

In addition to room size, there are other factors that influence the choice of BTUs for split air conditioners.

 Ceiling height

 Window and door size

 Location of the room

 Orientation of the house

 Insulation of the house

 Age of the house

 Location of the house

Consider the above factors together so that you can choose a suitable BTUs for your split air conditioner. 

Some common mistakes when using air conditioning

To ensure that your air conditioner performs at its best for as long as possible, you need to avoid some common mistakes. These mistakes are predictable and almost preventable. Failure to avoid these mistakes can also have unforeseen consequences that have nothing to do with the unit itself, such as sky-high electricity bills. This will save you a lot of time, money and effort in the long run. So here are the top three mistakes that air conditioning system owners make when it comes to their air conditioners:

 Buying an aircon that’s too big. When choosing an air conditioner for you, make sure you have measured or considered the size of the room in which the air conditioner will be placed. Once you have this information, you can choose the type and size of air conditioner accordingly. (As mentioned above)

 Using the wrong setting on the thermostat. Setting the thermostat lower will not speed up the cooling process at all, as the air conditioner will cool the room at its own rate. What is the solution? Either be patient or buy an air conditioner with a programmable thermostat so that it can cool the room before you enter it.

Neglecting to maintain your unit. Maintaining your unit regularly is key to guaranteeing your air conditioner lasts a long, long time. While this may seem like an extra cost, just remember that maintenance fees will always be cheaper than repair fees. So in the long run, you’ll actually be saving more money.

Preventing these mistakes can save you some money and time.

In general, there are many factors that determine the power of a split air conditioner. You can calculate the size of BTUs you need by roughly calculating the size of the room, or you can turn to a professional to get more accurate results. But it is important to choose the right split air conditioner. The time spent on the choice will provide you with some hidden benefits in the future.
