What Are Through The Wall Air Conditioners

A through-the-wall air conditioner is an air conditioner that is installed into the wall of a building, such that one side of the unit is fully exposed to the interior room and the other side is fully exposed to the exterior outdoor space.

So how does a window AC work exactly? To get down to basics: An air conditioner is an apparatus that uses energy to pump thermal energy against its normal hot-to-cold flow. Ultimately, nature will tend to make warmth enter your home until it is even with the outdoors. An air conditioner acts as a reverse heat pump to counteract this process to make the air cooler.

Through The Wall Ac Faqs

Even after reading the reviews and buying tips, you may still a few questions. The following are answers to wall AC FAQs

  • How much does a wall AC cost?

It depends. The majority of through-the-wall ACs are priced between $300 and $1,000. These prices vary based on several factors including AC size , efficiency, build quality, brand, features, and whether it works as a supplemental heater.

  • What wall AC sizes are available?

There are many sizes. The majority, however, are sized between 8,000 BTU and 25,000 BTU, with models in the 8,000 BTU to 14,000 BTU being especially common.

  • Whats EER vs. CEER?

Both of these are values used to rate the efficiency of an air conditioner. EER is short for Energy Efficiency Rating while SEER is Combined Energy Efficiency Ratio. EER is the older rating while CEER is a newer way to rate ACs. The main difference is that, unlike EER, CEER also takes into consideration the energy consumed while the unit is plugged in but not running. CEER values are typically lower than EER values.

  • Can I DIY-install a wall AC?

Yes, you can, as long as you have the necessary skills and tools. Also, DIY is much easier if you already have a hole through your wall and a sleeve ready for installation. If those two arent ready or if you need to adjust either the hole or sleeve, then its advisable to seek professional help. Here is how much wall air conditioner installation costs.

Q: What Is The Difference Between Through The Wall And Window Air Conditioner

The most obvious difference between through the wall and window air conditioners is the placement. You don’t need to be an expert on air conditioning to realize that one fits in one part of the home, and the other fits elsewhere.

Window air conditioners are installed at the window and fit on the windowsill to keep them balanced. Most of the time, they are secure enough to fit into standard windows, although this will vary depending on the size of your unit and the size of your window. You may need to renovate the window if your AC unit is too large, or even too small, to fit comfortably and securely.

Conversely, Through the wall air conditioners are fitted into the wall, and it’s no surprise where the name came from. Engineers will install them in an exterior wall and they use coils to bring in and generate air from outside, transferring it to cold air to cool your house.

Window air conditioners are less efficient compared to their wall alternatives. However, they are more affordable, easier to install, and also flexible. Wall air conditioners are a little trickier to set up, and they will require a sleeve to help support them without damaging the wall, as these units are heavier than other options. They also may not provide as wide of a total coverage area compared to other options, especially centralized air conditioner systems.

How Do Thru Wall Air Conditioners Work And What Are The Benefits Of Owning One

Best Through the Wall Air Conditioner (2021 Reviews & Buying Guide) Wall Mounted AC Unit

Thru wall air conditioners rather cleverly extract the heat from your room by sucking the hot air into the unit. Rather than spitting it back out, the heat is absorbed into evaporator coils and worked on by a compressor to increase the refrigerant temperature. Then, while the hot air is pumped out through the wall into the outdoors, cool air is sent as a replacement into your room.

The thru wall air conditioner has several benefits compared to other types of air conditioners such as window air conditioners. While window-mounted air conditioners are often stored out of sight in the winter, the thru-wall conditioner is a more permanent solution, meaning it will always be on-hand in case thereâs a sudden heat wave. Some thru wall air conditioners also double up as a heater, saving you bucks on a separate appliance.

As theyâre slotted firmly into a sleeve in the wall, thru wall air conditioners look less obtrusive for one. However, the design also works undercover to put a stopper on any cold drafts from gaps in the wall. This is a plus when it comes to energy efficiency, meaning itâs relatively cheaper to run than other types of AC units.

Installation: Wall & Electrical Requirements

Amana 7,400 BTU 230

Installing a thru-wall air conditioner is permanent, but not as hard as you may think. Follow the manufacturer’s instructions carefully for safe installation of your model, particularly when it comes to the size of the hole in your wall. The main things to consider before installing your model are which wall you use and the electrical requirements:

  • Wall Requirements: Using an appropriate wall is the most important part of installation. Be sure to check for plumbing or electrical structures that may be inside the wall before you begin. Consider consulting a professional if you feel unsure, as the hole needs to be measured and cut precisely.
  • Exterior Wall Needed: All thru-wall ACs must be vented outside, so they must be installed in an exterior wall. Also take into account wall thickness, double checking both the unit and sleeve dimensions before you start. Consult the owner’s manual for any additional requirements.
  • Electrical Requirements: Always check the voltage specification for the model selected to ensure that the AC will work in your home. Many new thru-wall ACs use standard 110-120-volt plugs, but some larger or older units use 220 volts. For models with voltage requirements that dont match yours, you may need to install special electrical wiring or consult an electrician. Locate the AC on the wall well within reach of an appropriate outlet most manufacturers don’t suggest altering or extending the cord.

Replacing An Existing Unit

FRIEDRICH Thru The Wall Air Conditioning or Heat Pump AC Units | Weekend Handyman

Replacing a thru-wall air conditioner is fairly simple the main consideration is the wall sleeve. Every through-the-wall air conditioner requires some type of wall sleeve for support. Without this, your wall cannot support the weight of the AC and will become deformed or seriously damaged.

Wall Sleeve Options

When replacing an old unit, the existing traditional wall sleeve is usually compatible with the new model, if its a similar cooling size . Fortunately, many air conditioner brands make standard thru-wall AC sizes that fit sleeves from other brands, so you arent limited by that. This makes installation simple. If the sleeve fits, simply buy the new thru-wall unit and install it. You can find information on wall sleeve size in the owners manual to check against the size of the one you have.

Note: Most of our units include a link to the owners manual on the right side of the product page, so you can check before you buy.

A through-the-wall AC with a slide-out chassis essentially uses the surrounding cabinet as the wall sleeve. The AC unit slides out of the cabinet which is then installed in the wall. The thru-wall AC slides back into the cabinet to complete the installation. Double-check the size of the hole required when replacing an old unit using a traditional wall sleeve, with a new unit that has a slide-out chassis.
