Step 2. Physical and Structural Restrictions


Of course, now that you are familiar with the different types of air conditioners and already have top options to pick from, don’t forget that there are still many factors to consider. Next in line is to consider both the physical and structural restrictions. 

Here’s what you should know:

Physical Space

Take note that several issues might happen if you put an air conditioner too powerful for the room in which it is placed. The unit would alternate between cycling on and off a lot often. Some of these issues include:

  • high levels of humidity in the room
  • consume higher amounts of electricity, early wear, and tear of the machinery

Also, the room might not be properly cooled if the unit is underpowered and too small. It might as well increase energy costs. So, choosing an air conditioner’s suitable size is best by measuring the room or space you intend to place the unit in. 

Air Conditioner Size

To determine the right size of the air conditioner, you need a measuring tape. Follow these steps:

  • measure the room’s length and width in feet
  • multiply the numbers to get the square footage

After this, you can already shop for the right size of AC. But, you still need to match the square footage to the correct BTU of the air conditioner. The higher the BTU number, then the greater the cooling power of the AC. 

Structural Restrictions

Based on the type of apartment or house you have, there is a certain legal restriction on the type of AC you could install. For example, some apartment complexes and residential zones might not allow you to install window air units since a part of them hangs out the window. 

You might also not install through-the-wall units or ductless mini-splits since these require structural changes to the walls. Well, portable air conditioners are allowed because they don’t hang out the windows, or there is no need for installation. 


Air Conditioner Buying Guide


Step 3. Identify the Short List of Needs


So, what do you exactly need for an air conditioner? Here are sets of questions to consider:

Q: Do you consider heavy installation?

A: Extensive installation might be needed by ductless mini splits, and central air conditioners and professionals must do so. Other types need minimal effort, like portable and window air conditioners

Q: Do you want an AC that could be moved easily?

A: For some, it is essential to have a cooling unit that could be easily moved and so the portable air conditioner is the only option for this. 

Q: Do you want to conserve much energy as possible?

A: If conserving energy is important, then choose a unit that keeps the expenses low. Take note that a central air conditioner is the one that costs most, and the cheapest ones are the through the wall and window air conditioners. Portable and ductless fall in the middle. 

Q: How about the level of noise?

A: The decibel scale differs widely in ACs. Central air conditioners are considered the quietest, followed by ductless mini-splits. Air conditioners are a bit tolerable through the wall and window because the noisiest parts are located in another room or outdoors. And portable air conditioners are considered the loudest and could be as loud as vacuum cleaners. 


Final Thoughts

Now that you’ve learned important details about the various types of air conditioners, along with options to choose from, and you are as well provided with factors to consider, it is now the time for you to make your final decision on whether which air conditioner is the right one for you.
