What if I told you that installing a through-the-wall air conditioner can be done in a matter of minutes?

If such is the case, the information in this guide may be useful to you.

We’ll walk you through the process of installing a wall AC unit so that you can get started right away.

To get the work done well, the process isn’t as difficult as you may imagine, but it does require some preparation and patience.

Let’s get started, then.

What Is a Through the Wall Air Conditioner?

Window air conditioners and heat pumps are probably familiar to you. Small flats to large condominiums have them, and they’re everywhere in between. Window air conditioners and heat pumps are fairly similar to through-the-wall air conditioners. Window air conditioners are installed inside the window frame, whereas through-the-wall air conditioners are installed in an opening cut into the wall of your building.

Window ACs can hinder your view from the window, while through-the-wall ACs don’t. However, you’ll need to cut a hole in your wall to do this. Take a closer look at the main differences.

Differences Between Window Air Conditioners and Through the Wall Air Conditioners

The fundamental distinctions between window and through-the-wall air conditioners will now be examined in depth.

1. Location and Installation

With window and through the wall air conditioners, the site of installation is a key difference. An air conditioner can be installed in an outside wall using a through-the-wall unit. Since they require a wall opening, they are not suited for people who are renting a home.

Window air conditioners, on the other hand, are put inside the window frame but block your view out of the window. It is not necessary to permanently install these air conditioners, as they can be uninstalled with ease.

2. Flexibility

Window air conditioners, in contrast to through-the-wall units, can be uninstalled when not in use. During the winter, you may put them away and free up some window space.

3. Energy-Efficiency

When it comes to air conditioning, energy efficiency is critical. Small rooms may be effectively cooled or heated with any of these energy-efficient air conditioners. Wall air conditioners, on the other hand, are more energy-efficient than window air conditioners because of the way they are installed.

Window-mounted air conditioners are more prone to leaks and gaps due to their placement. When it comes to air leaks, no matter how tightly you seal them, chilly air might still get out. In order to maintain a comfortable temperature, window air conditioners must run for an extended period of time. Wall air conditioners, on the other hand, nestle snugly into the wall and don’t allow much cool or warm air to escape via the window.

4. Noise

If you are a light sleeper and frequently wake up due to noise, through the wall air conditioners are the best option for you. Wall air conditioners are quieter than window air conditioners, which can be irritating to the eardrums.

5. Interchangeability

Some wall air conditioners may be interchangeable with window air conditioners, depending on the design. In contrast, through-the-wall air conditioners are too heavy to be installed in window frames, thus this restriction does not apply to them. The installers, on the other hand, may not follow the manufacturer’s instructions, attempting to put the air conditioner in a location for which they were not designed, voiding the warranty.

Having your air conditioner installed incorrectly or placed in an inconvenient area might lead it to perform inefficiently and leave you feeling hot and bothered!

The Similarities Between Through the Wall and Window Air Conditioners

The wall air conditioners and window air conditioners are different in many ways, but they share some similarities. The purpose of both air conditioners is to cool one room or two smaller rooms at a time. They are designed for smaller spaces.

Why Should You Get a Through The Wall Air Conditioner?

Air conditioners mounted on walls and those mounted on windows differ in many respects, but they also have several features in common. Both air conditioners are designed to cool a single room or a pair of smaller rooms simultaneously. As a result, they are ideal for tiny places.

Even if you’re not ready to buy yet, you might want to read this short part if you’re curious about the installation process before making a final decision.

Through-the-wall air conditioners have become more popular in recent years.

Because of their low price, high cooling capacity, and ability to be permanently installed, these appliances are now on par with both window and portable air conditioners.

Next, we’ll go over the many advantages of installing a through-the-wall air conditioner, but first, we encourage you to read our guide to the finest wall mounted air conditioner units. The information you’ll find there will assist you in making an informed decision about which gadget best suits your requirements and budget.

The following are the top three advantages of using a wall AC unit:

  • Average-sized air conditioners through the wall don’t need a lot of electricity to run. This helps keep your utility costs down and your wallet full. Running the unit costs most people between $20 and $30 a month.
  • This is a long-term answer to your cooling problems because of the fact that these units are permanently installed in your walls. Because alternative air conditioners, such as window units and portable units, must be uninstalled and stored during the winter, they are less convenient. Some people may find that a hassle.
  • Some wall air conditioners, in addition to cooling, also function as heaters. With this, you get year-round comfort at the lowest possible price.

How To Install A Through The Wall Air Conditioner

Tools Required

You’ll need to gather the necessary equipment before beginning the installation process for your through-the-wall air conditioner.

Make sure your installation goes as smoothly as possible by following these steps.

What Are Through the Wall Air Conditioners? An In-Depth Guide

The following is a list of the things you’ll need to get this device up and running:.

  • You should get a sleeve (sometimes known as a “bracket”) with your order. Otherwise, make a purchase.)
  • Guns for caulking
  • Caulk made of silicone
  • A Tape Measure
  • a tool for locating potential mates (or you can use a small penny nail for finding the studs)
  • Paint
  • Pencil
  • Pry Bar:
  • Saw, Circular
  • Cutting with a Handsaw
  • Hammer
  • Nails
  • Level
  • a number of 2 x 4 timber (for framing)
  • There are drills as well as drill bits
  • Utility Knife
  • The utility knife
  • a utility knife
  • Drywall Knife

Step 1: Choose a Spot

Knife for Cutting Drywall

A Knife for Cutting Dry Wall

Keep the bottom of the wall AC unit 1 to 5 feet above the floor as a safety precaution as well. If the air filter is set too high, it could cause condensation to build on the ceiling, therefore this will help to reduce the quantity of dust it collects from the floor.

Step 2: Mark the Wall Studs

Wall studs (2 x 4 lumber) are used to build and support walls, and they’re typically 16 inches apart.

Mark the studs so you know where to start cutting through the drywall after you’ve chosen a position for your appliance. If you can, you should try to minimize the amount of wall studs that must be removed.

There are two solutions available to you in this situation:

  1. Locating the studs by using a stud finder
  2. Finding a location where the sound transforms from hollow to solid by tapping on the wall with your knuckles A penny nail was then hammered into the wall to verify the correct location. It’s great if you get a stud. If it doesn’t work, try again.

Mark three or four wall studs with an X on the drywall using a pencil after you’ve located them.

Take a measurement of the air conditioner’s width, and use it to mark the studs in the wall where the unit will be installed. An installation guide, which you can tape to the wall and trace the outline of, should have arrived with your appliances as well. If not, you can accomplish this with the sleeve (bracket).

You should position the guide paper or sleeve so that you cut through the fewest amount of studs possible when using it.

Step 3: Turn Off Power to the Room

Make sure that the breaker in your house’s electrical panel (breaker box) is flipped. You don’t want to accidently cut through electrical wires when you’re cutting through the wall in the next phase.

Run an extension cord from another room with electricity to power your saw and drill.

Step 4: Making the Hole

Trace the outline of the air conditioner on the wall using the guiding paper or sleeve provided.

During the marking phase, use a level tool to ensure that your outline is level.

Then, draw a second outline 2 12 inches larger than the first. The 2 x 4 wooden pieces will serve as a sturdy support frame for the unit if you do this.

Remove all of the drywall to reveal the wall studs beneath. You should also cut away any insulation that is in the wall to match the opening you made in the wall.

Step 5: Cut Through the Wall Studs

In order to make the wall opening flush with its contour, use a circular saw to cut the wall studs that are located inside it.

Step 6: Construct a Frame for the Air Conditioner

Using the dimensions of the wall opening, cut two 2 x 4’s to the same length as the wall.

Using a tape measure, deduct the aggregate thickness of the two 2 x 4s from the wall opening’s height. Next, cut them to the same lengths you did with the first set.

Make a frame out of those four 2 × 4 pieces of lumber. Make sure they’re all in place.

Build a two-by-four frame, slide it into the opening, and nail it to the wall studs to secure it.

Step 7: Create a Hole In The Exterior Wall

Each of the four corners of the inside frame that punches through the outer wall should be drilled using a drill.

The holes in the outer wall will serve as a guide for you to determine precisely where you need to cut.

With your pencil and a level, draw four straight lines to connect these drill holes on the exterior wall.

With a pencil and a level, draw four straight lines on the outer wall to link these drill holes.

Step 8: Installing the Through the Wall AC Unit

To install the metal sleeve, follow the manufacturer’s instructions and insert it into the wall opening.

Incorporate the gadget into its sleeve, and then fasten it to the bracket.

Connect the power cord to an available outlet.

Step 9: Completing the Installation

Cut and fix any exposed drywall around the appliance with the new material.

Use drywall nails to secure it in place.

Using drywall compound and a drywall knife, fill in any cracks or holes.

In order to match the color of the wall, you should prime and paint the drywall.

A thick caulk bead should be applied to all of the unit’s external and interior edges using a caulking gun and silicone caulk. Having this installed will keep the air from leaking in and out of the house.

If you like a more polished look, you can add trim or molding to the unit.

Step 10:  Turn the Power Back On

Turn the breaker back on in the room, so that the room’s electricity can be restored.

Once you’ve cooled down, switch on your air conditioner and enjoy.

Installation isn’t difficult if you have the right tools and follow the right instructions, as you’ve seen. For those who don’t want to spend a lot of money, owning a wall-mounted air conditioner is a terrific option.

How Does a Through the Wall Air Conditioner Work?

A through-the-wall air conditioner is a self-contained piece of technology. As with any other air conditioner, the fundamental job of a wall unit is to draw in warm air, chill it, and then return it to the room. Hot air from inside the room is drawn in by the unit. The condenser receives the hot air and uses it to cool it to the desired temperature. The conditioned air is then returned to the room. As a byproduct of this operation, hot air is generated by the motor and expelled into the surrounding environment via the vents.

Features of Through the Wall Air Conditioner

A wide number of benefits are available with through-the-wall air containers. If you’re about to buy something, you should keep these things in mind:

Digital Controls

Temperature settings can be altered using digital controls. Use the numbers instead of the dial to set the temperature more precisely.

Washable Air Filter

Dirt and other particles accumulate in air filters, lowering the performance of air conditioners. Using a washable air filter in a through-the-wall air conditioner will save you money in the long run.

Remote Control

New through-the-wall air conditioners come equipped with remote controls, making it much easier to adjust the AC settings. These air conditioners can also be paired with a smart AC controller that allows you to control them from your smartphone.

Auto Restart

This option allows the motor to be automatically restarted in the event of a power failure. When the electricity is restored, the air conditioner resumes operating at the previously configured temperature..

Louvers Adjustment

You have complete control over where the lovers are placed. Automatic swing louvers on some models distribute cool air about the room to keep the temperature just right!

Heat Mode

Heat is an option on many models. In the winter, they can be very handy and convenient.

Programmable Timer

If a model allows you to schedule your air conditioning, you can turn it on before you need it. A conditioned room awaits you when you return home. You can use a smart AC controller to set weekly schedules from your phone if your window or wall AC does not have this feature.

Energy Efficiency

If you’re looking for a refrigerator, make sure it’s Energy Star certified and includes the other qualities listed above. If you want to save money on your electricity bill, go for a model with a higher EER (Energy Efficient Rating). An EER rating of 9.7 or more is generally considered to be the best in terms of efficiency and cost-effectiveness.

Through the Wall AC Sizing Guide

The size of your home’s air conditioners is dependent on a variety of factors. It’s critical that you pick the proper size for your room. A larger unit will use more energy, resulting in higher monthly expenses, while a smaller unit will put more strain on the machine.

The greater your air conditioner’s cooling capacity, the more BTUs it has. This means that a higher BTU is needed for larger rooms. The US Department of Energy’s recommendations for room air conditioner sizing are presented here. Decide on a unit that is the right size for your space in order to get the most out of your AC.

Why Choose a Through the Wall Air Conditioner?

Choosing an air conditioner for your room may seem like a daunting task at first, but it all comes down to personal style and demands. Window air conditioners are less efficient than through-the-wall air conditioners because they don’t enable cooled or warmed air to escape from the room.

People who wish to be able to remove their air conditioning equipment select window units. Even though it’s hot outside, you want your windows to be as airtight as possible while it’s cold outside. Window air conditioners are often taken out and stored for the winter months in this situation.

You don’t want to have to do this every season, so you’re looking for a long-term solution that doesn’t compromise your room’s seal. A through-the-wall air conditioner is the ideal solution in this situation. As a bonus, the view from the window is unimpeded so that even more energy savings can be achieved!!

Make Through the Wall Air Conditioners Smart!

If your through-the-wall air conditioner comes with an IR remote control, you can easily turn it smart. The ability to use your smartphone as a remote control for your air conditioner qualifies as a sign of smarts. An optimal temperature range when you do not have to deal with the difficulty of keeping an appropriate temperature at home during sleep or during a small gathering. How did you manage to do this? A smart AC controller can be purchased for a relatively low price.

Smart AC controllers allow you to take advantage of these and many other benefits.. As a notable example, the controllers’ Comfy Mode can be found in the Cielo Breez line. Your air conditioner will run in accordance with the settings you specify to maintain the desired temperature or humidity range. You may also save 25% on your energy bill by using a smart AC controller!

The Downside of Having a Wall AC

In spite of its convenience, wall ACs require a long-term investment. To replace your through-the-wall AC with a newer one, you’ll have to create a sizable hole in the wall, which will need to be patched and repainted. Proper insulation is yet another consideration. Drafts and insects can get in through the opening if it is not insulated.

Cooling your home with a through-the-wall air conditioner is a convenient option. For settings when noise is a concern, these devices are ideal. They can be put in bedrooms, dorm rooms, hotel rooms, assisted-living facilities, etc. If this type of air conditioner meets your needs, order it right now.
