Frigidaire's FRA103KT1 10,000 BTU 115V Casement/Slider Room Air Conditioner is the perfect solution for cooling rooms with casement windows and horizontal sliding windows up to 500 square feet. In the sweltering heat of summer, there's nothing more frustrating than trying to install a portable air conditioner in a casement or crank window. The window kit that comes with most portable air conditioners is designed to be installed with a traditional sliding window, but that doesn't mean you can't enjoy the clean look of a crank window and the cool comfort your new portable air conditioner provides. The easiest way to vent your portable air conditioner with a casing or crank windows is to fabricate an insert to fit into the window. This way you can keep the cool air in and keep the hot summer air out.Things to Keep in Mind:Be sure to plan out the details for cutting or drilling before you get to the hardware store. Many portable air conditioner manufacturer's recommend that the air conditioning unit be placed as close as possible to the installation site, so that the venting hose doesn't need to be extended.

This is especially important to think about before you drill a hole in the Plexiglas or Styrofoam. An inch one way or the other may impact whether or not the hose can reach the hole that's been drilled. Now that you've brought your new insert home, it's time to install it in your window. To do this, open your crank window and hold it in place with a latch. By attaching the latch to the widow and window frame, you're helping prevent possible damage to the open window. Make sure the widow is reasonably secure and won't get damaged if there is a breeze or light wind. Next, you need to secure the insert to the window frame. There are several ways to do this. One idea is to use twist clamps to secure the insert. If you know you're going to use Plexiglas, another idea is to use retainer clips (like on the back of a picture frame) to hold the Styrofoam or Plexiglas in place. Since your insert is the only thing that divides your home from the outdoors, it's important to seal it and make sure that it's reasonably weatherproof.

To do this you can caulk where the window frame and casing meets. Another option is to use self-adhesive weather stripping. You should be able to find these tools at your local hardware store or at larger home improvement stores. danby designer ac unitIf you're going to use self-adhesive weather stripping, you may want to attach it to the insert before you secure the insert to the window frame. coleman ac units for rvOne thing you'll want to keep in mind is that the weather stripping should fit tightly between the window frame and the insert so that it forms an effective seal. noise from air conditioning units victoriaThe weather stripping should have enough pressure on it so that it compresses and is about half of its normal thickness where the window frame and insert meet.

Making sure the weather stripping fits snugly is key to weatherproofing your insert. Another weatherproofing option is to simply run the weatherproof stripping along the area where the window frame and insert meet. To make extra sure the window is as weatherproof as possible, you can fit the weather proof stripping between the wall and insert and also run it over the area where they meet. If you use this method, you can help ensure that your insert is as weather proof as you can possibly make it. Now that you've fabricated your insert, installed it and made sure it's weatherproof, it's time to set up your portable air conditioner. The last step is attaching the hose to your insert.  Congratulations, now you can relax and enjoy your portable air conditioner. Be sure to follow the manufacturer's instructions for operating your new portable air conditioner, and look forward to a comfortably cool summer!Dear Lifehacker,It just got sunny in Seattle and no one here has a real air conditioner.

I need to find something to make it through the summer. Do I have any alternatives besides a small window unit? What's the most effective air conditioner I can use for an apartment? Dear Sweltering,From here in Atlanta, I feel your hot, sticky pain. The bad news is that if you're looking to keep a room cool, no matter what solution you go with, you'll need to pump hot air from the inside of your house to the outside. This means you'll either be going through a window or a wall. Unlike heating a room, which can be done with a space heater that you just plug into an outlet, air conditioning requires a lot more parts and can get expensive. The good news, however, is you have plenty of options to choose from. 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 like this one 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. 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.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.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. 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.We'd be remiss not to mention other alternatives to air conditioning.
