Thru-The-Wall Air Conditioners Explained

This post should describe the differences between the two types of thru-the-wall room air conditioning units.

The first type of wall unit is necessary when there is not yet an air conditioner installed.  A wall unit that has a slide-out chassis should be installed.  These units should already come with their own sleeve for easy installation.  To install, the chassis (guts) should be slid-out of its sleeve, a hole should be cut approximately 1/4″ larger than the size of the unit’s sleeve in to the wall.  The sleeve should be screwed into a stud in the wall, then the guts should be slid into the sleeve.  This type of wall unit uses a sleeve for installation because if something goes wrong in the future, it can easily be removed from its sleeve for repair or maintenance.

The second type of thru-the-wall air conditioner sold (more of a specialty item) comes into play if there is already an air conditioner installed in the wall (like the first type of unit discussed above) that needs to be replaced.  Although a little more expensive than the first type of wall unit on average, these air conditioners are much less expensive to install because a new hole does not need to be cut or an existing hole does not need to be altered.  Most relacement thru-the-wall air conditioners are smaller than 26″ wide and 16″ tall, since the old “standard” wall unit was about that size.  These thru-the-wall units are solid-sided and rear-vented so that they can slide into any existing sleeve without any trouble breathing which may result in a unit overheating.  Also, since these units are typically smaller than an existing wall air conditioner (often sized 24″ wide and 14 1/2″ tall), they come with a trim-kit that slides over the front of the air conditioner to fill most gaps between the unit and the existing sleeve.

Solid-sided, rear-vented thru-the-wall replacement air conditioner

Often times, the question comes up as to why the first type of wall air conditioner can’t be installed in to an existing sleeve.  Well, as discussed, these units have side-vents that allow the unit to breath, and more often than not, the side-vents in the unit will not match the side-vents in the existing sleeve and can cause the unit to overheat and damage its compressor, thereby rendering the unit inoperable, often times without any waranty coverage due to the fact that the unit being installed improperly.

Another distinguishing factor between these two types of air conditioners is that the first type of unit can usually also be installed in a double-hung window and often times comes with a side accordian sleeve (which can be removed for a wall installation).

What’s the best Air Conditioning for your home?

Everything you need to know in the purchase of the right AC unit for you, as summer heat is quickly approaching. The good news is that you have plenty of options to choose from. Keep in mind, all of the following possibilities can only cool one to two rooms at a time, max. They’ll also need a way to pump hot air from the inside of a building to the outside. To get started, pick the highest priority rooms that have outside walls, then use a BTU calculator to figure out how much cooling power you need for a given room size. Also, be sure to brush up on your A/C terminology before you go shopping. From there, it’s time to decide which type of unit is best for your home.

Window Units

Before you rule out window units entirely, be sure you’ve exhausted all your options. While some A/C units are a couple feet wide and designed for roughly standard size windows, there are mini air conditioners that can get as small as 14″ wide. Many of these are designed for casement windows, which open horizontally instead of vertically like most slide windows. These devices are taller instead of wider. It may be difficult to find one that fits perfectly, but it’s worth taking the extra time to look around before moving on to the more complex options.

The advantage with window units is that all the important parts—the compressor, condenser, expansion valve/coil, etc.—are all in one big box. The installation of these is much simpler and they’re very portable. Be sure to thoroughly search for a window unit before exploring other options. Find out what type of window you have and see if other people have a similar problem. If you absolutely can’t find a window unit, it’s time to move on to more elaborate solutions. Window units provide the most cost-effective and painless solution to cooling a single room. The units are relatively cheap and they have a lot of cooling power. If you’re renting or want to avoid serious wall modification, this is the way to go.

Portable Units

The simplest non-window based option is a portable A/C unit. These are devices that usually sit on the floor near a window. Hoses will carry air inside and out through a window. Typically, these units will come with adjustable hose frames to place in the window that keep them in place. Technically, all the parts are physically in one box, but you’ll still need a connection to the outside world for them to function.

When deciding on a portable unit, you’ll have to choose between single or dual hose systems. A single hose system uses just one tube to pump hot air out of the building. The trouble is that this reduces the air pressure inside your home. This causes more hot air from the outside to come in through cracks in doors and windows. The A/C unit has to work extra hard as a result, which is a terribly inefficient system. It’s not a huge concern if you’re trying to cool a small space, and these devices are generally less expensive. For a larger home, though, the extra energy costs can rack up fast.

Dual-hose units, on the other hand, cool the hot air that’s already inside the house and returns it to the room from whence it came. To keep the unit itself from overheating, a second intake hose pumps in air from the outside to cool the device and then pushes it right back out again. This system is much more efficient because the device isn’t constantly working against itself. Dual-hose systems are almost always the way to go unless you only need to cool a very, very small area. Just keep in mind that some units can get pricey.

Whichever model you choose to go with, though, a portable hose unit should probably be your last resort. This is for those who absolutely can’t use a window unit and aren’t able to do any wall modifications. As Consumer Reports points out, they’re costly and not very efficient in general. A similarly-sized window unit will cool better than its portable counterpart.

Ductless/Split Units

This is where you start to get into some heavy lifting, but you also get a much nicer unit. Split units consist of two parts: the indoor component that you can mount on a wall, and the outdoor component that sits cozily next to your home. The upside to this is that you can hang the device in a place that looks good instead of setting a giant box awkwardly near whatever window is available. The downside is you’ll almost certainly have to start drilling holes.

A “ductless” system might sound like a bit of a misnomer to the layman. All “ductless” means is that you don’t need to have a complex system of action movie hero escape routes running throughout your entire home. You will, however, need hoses running from the inside of the room you want to cool to the outside condenser unit.

The good news is that you may not need to do too much work on your walls. If you know how to run wires or hoses through walls, split units are comparatively simple to install on your own. As with any project where you have to drill holes in a wall, though, don’t tackle a project like this unless you’re sure you know what you’re doing.

A split system is a great option if you live in a hot region and need to cool a large area inside your home. Their cooling power is among the closest you can get to real central air without tearing apart all your walls and ceilings to install. The two main disadvantages here is that these units will be among the more expensive you can find, and you can’t move them from room to room like you can with a window or portable unit. You will also still need multiple units to cool separate rooms.


Wall Units

By far, the most complicated option is a wall mounted air conditioner unit (otherwise known as where Dexter keeps his secret box). This type of device is very similar to the window system, except instead of using a pre-existing hole in your wall, you have to cut one instead. This involves watching out for pipes, wall studs, and generally ensuring the stability of your home while you make a hole big enough to fit a small person through in the side of your abode.

Wall units are the kind of project where if you don’t already know you can do it on your own, you should talk to a professional before getting started. The upside to going this route is that you can find units that are much closer in price to the inexpensive window-based options. Of course, what you save in hardware costs you could end up spending on installation. Also, this may not be an option if you live in an apartment or dorm room. However, they have a lot more cooling power than portable A/C units, and are even more efficient than window units due to the much tighter seal. The energy savings can be well worth the trouble over the long term.

These replacement air conditioners with solid-sides and rear-vents are our most popular items since many multifamily apartments replace these on a regular basis.

Getting Cool And Staying Cool–Summer’s Here

I’ve grown up enjoying the heat of Southern California.  There were always pools to go swim in, beaches to lie out at, and a cool house to come home to.  My family’s always had air conditioning.  In the home that I grew up in, we always had central air conditioning (HVAC).  The compressor (condensing unit) sat outside my house, ducts ran throughout the ceiling inside, connecting to a furnace in our attic.  It kept each room cool in the Summertime and Warm in the cooler Winters.  So refreshing.

When I moved out for the first time, it was into an apartment that had an air conditioner in the living room wall.  Then, I rented a condo with an air conditioner in the living room wall and an air conditioner in my bedroom window.   Unfortunately, that was the only window I had in my bedroom, and couldn’t enjoy the beautiful view of the park across the street!

Window and wall air conditoners are typically used in multi-family buildings like apartments, condominiums and town homes.  In these environments, they are usually really old (some more than 20 years old), unsightly, noisy, and so  un-environmentally friendly that they accounted for a nice chunk of our electric bill each month!  Landlords often think that replacing window or wall air conditioners is expensive and can make their building look unsightly.

In fact, there are many reasons why a landlord should  and absolutely no reason why a landlord should not replace or install a new window or wall air conditioner. Here’s why:

Keep tenants happy. First and foremost, a happy tenant is more often than not, a good tenant.  After a long day at the office, it’s tougher to have clear, positive karma without the nice cool breeze  of an air conditioner on a warm, humid night.

Cool at any price. First of all, if a landlord doesn’t want to spend the money for a new air conditioner, often times tenants would be willing to pay an additional few bucks a month in their rent to stay cool during those hot, humid  Summers. Window air conditioners that would cool a small bedroom up to approximately 150 square feet can be purchased for about $70 after utility rebates!

Out of sight, out of mind. If the landlord doesn’t want the boxy-appearance of a sleeve sticking out of their exterior windows or walls, they can recommend that the tenant purchase a portable unit.  Although the hot air still needs to vent outside of the room being cooled, the hose does not extend past the screen of an open window.

Process of buying an air conditioner is a pain! Buying an air conditioner is actually a pretty simple thing to do.  Once you answer only a few questions, any landlord or manager will know exactly what they need to buy

Quieter, more appealing options. Again, if you don’t want the boxy-appearance of a sleeve sticking out of the exterior windows or walls of your building, and don’t mind spending a few extra bucks on the installation of a ductless mini-split air conditioner, these are a great option!  Want to know more?  Click here.
