Why Should I Get a Through-the-Wall Air Conditioner?

There are several benefits to wall air conditioners. Consider some of these benefits of purchasing a through-the-wall air conditioner.

Why Should I Get a Through-the-Wall Air Conditioner
  • Energy Efficiency: Most wall conditioners have high efficiency ratings. You can cool a single room, and they usually have tighter seals around them compared to window units. They also have less of a draft.
  • Safety: Wall air conditioners are usually more secure than window units. They are also hard to remove, so burglars are less likely to remove a wall unit. Even if it is dislodged, most window units are too small for a human to fit.
  • Look: It may only be a concern to some, but wall air conditioners still allow you to see out your window, and they usually look better than a bulky wall unit.
  • Dual Features: Some wall units have both a heating and cooling option. This means you can use it in the summer and the winter. This makes the cost a little more reasonable.

What Size AC Unit Do I Need?

You always need to consider the size of your room and how much power you need to cool the room.

If you get a unit that is too powerful, you will waste money on wasted power. The modes may also not work as efficiently, which means it will actually cost you more to run the unit.

If you get a unit that does not have enough power then you need to run the AC more often, which will also increase your energy bill.

You should take a few things into consideration when buying an AC unit that works for your space. 

  • The size of your room: always measure the square footage of your room
  • Compare the square footage to the BTU Number of the air conditioner: each unit will include the BTU number, which helps you calculate the room that the unit can efficiently cool. Most units will tell you the room capacity. 
  • Voltage: Most units come in either 115V or 230V. You need to know the voltage because some voltages require special outlets.

Features to Consider in Air Conditioners

However, since they fit more snugly, there are less drafts and there are more options for locations. However, they usually have lower BTUs and can cover fewer square feet.

Some units have several different modes. These can include a dehumidifying mode, which is an additional benefit of these units. They may have fan-only modes, which help circulate air without running the compressor. Sleep modes are energy efficient and slowly raise the temperature as you sleep.

You should also consider the kind of controls you want. Many units come with a remote control for easy control in any part of the room. Most come with digital settings for easy use and reading.

You can also look at the Energy Efficiency Ration (EER). Those with high EERs have great levels of efficiency. This may be of considerable importance to you, especially if you are getting this unit to reduce costs in your home.
