Air conditioning unit inside room?

Question

It's summer time and my room gets extremely hot and the fan that I have in there now is just not working. I was thinking about buying one of those a/c units and my question is if it is possible to not have to do any work to my windows since my manager wont let me and instead to just put the a/c unit next to the window having the back of it towards the window so that the hot air will blow outside but not having the actual unit sticking out the window. I'm not sure if this would work and would it cause problems??

Answer 1

You' re running the risk of burning out the compressor from overheating or having it just simply not work. Somehow, you'd have to figure out a way to get the condenser air intake and discharge (fresh air in and hot air out) to the outside without causing restriction to the system and short-cycling the two. There are some A/C units made which are meant to go inside a room and a tube takes the air outside, but their probably more expensive than you'll want to pay.

Here are a couple things to check on your own. 1) On the outside unit you have very thin fins that go all the way around the unit, they should all be straight and/or not dinged up, don't touch them, you can bend them. A couple dings here and there are fine but they should also be clean, you can use a garden hose to spray the fins off. 2) The smaller diameter copper refridgent line, this should not have the insulation on it, the bigger one should have pipe insulation on it, the smaller one should feel warm to touch with your hand, not hot and not cool or room temp. 3) Where the ductwork connects to the furnace right on top, this is where the A coil sits (unless you have a downflow furnace) and you should see the two copper lines coming from the outside connecting at this point. Use a meat thermometer and place the probe into the ductwork as close as you can ABOVE the A coil, about 18"-24" above the top of the furnace. Usually you can get it in at a seam or corner of the ductwork, leave it in there probably about 10 minutes to get a good reading and write it down. Then do the same for the return air, usually right near the filter along the bottom side of the furnace (unless it's a downflow furnace). You should have a temperature difference of 14F-22F degrees. 4) Another item to check is your filter, do not use the cheapy $.50-$1.00 filters you can see through, at least use a pleated style which is only a few bucks a filter. Or you may have a Space-Gard type which is 4"-6" wide versus the cheaper ones about 1/2" wide. Make sure the filter is clean. 5) Some house layouts just do not work efficently for heating & cooling, the 2nd story on a cape cod style are pretty difficult to heat/cool well, basically long duct lines. If that's the case having a in-line duct bootser may help with that. Good Luck!

You should be able to get a window unit and install it in your rental without any modification to the window.

Your primary concern is will you have enough electrical power to run the unit? When you go to the store, you will need to buy one that runs on 110v and less than 20amps. Home (and apartment) wiring is only rated for 15 amps, so you may not be able to plug one in at your location.

If you do have adequate power, purchase a unit that is designed for unsupported window installation. You can slide the unit into the window opening, and lower the window sash, then fill the sides with plywood, foam, or even cardboard. You will only need this thing for a few months, it will be unsightly, but in September you can pull it out and store it for the winter.

Answer 4

You will need to have the back coils as far out of the window as permissible because they need to transfer the heat to the outside air.

In addition, you will need to seal around the edges of the AC unit and your window to keep from pulling hot air into the room, otherwise the AC will be working against itself and will not cool the room.

Answer 5

if you run it inside with no way to vent condenser air you will be in a hot, sweaty, flooded floor hell. Condensate made by the evaporator has to run out side and the condenser kicks out all the hot aire from the room as well as the heat of compression from the compressor. You will be hotter than you started. An evaporative is one idea and is a ceiling fan to bring the hot air up and away from you.

Answer 6

Get an evaporative cooler instead of an air conditioner. You do not need to have the unit out the window.
This uses the evaporation of water to cool the air.

Answer 7

Try looking into room ac units. They r self contained and about as big as the old steam radiators. Just dont get sticker shock! A unit that cools about 500 sq ft aint cheap
