Is a through-the-wall air conditioner a standard size?

Question

I have two old through-the-wall air conditioners in my house which I "inherited" from the previous owner. They seem to be from the late 1970s or 1980s. I am hoping to replace them at some point, but am unsure about their size.

I measured the wall opening and it is 20" wide and 14" high. But it seems like all the through-the-wall units I look at online are 24" wide and 14.5" high. Did they change the standard size at some point or do I just have odd-sized units?

Answer 1

Wall type airconditioners vary their sizes according to the size of the compressor. I think those old a/c units range from 1, 1.5, and 2 horsepower compressors basing from the dimensions you said. You can check this out from the metal faceplate attached at the body of the unit's housing. Just remember that using those old models consume too much electricity than the new ones nowadays. My advise is you sell those and buy yourself new models smaller in sizes but much effective and economical.

Answer 2

If that's a condensating window a/c unit then water is going to drip from it down into your wall inflicting all varieties of important issues for you. Window units are meant to be put in homestead windows with the lower back of the unit tilting downwards somewhat so as that it may drip outdoors. If that's a brilliant unit (oftentimes a 220) then it additionally could desire to be supported or it may rip your window top on out and fall to the floor. The smaller a hundred and ten units do not could desire to be supported.

Answer 3

Wall or window units have adjustable sides and can be set inside an open window. Wall units are installed flush into an exterior wall.

Answer 4
