Question:
I've recently bought a house, it has three 15+ year old Friedrich Air Conditioners
that do not work, I was wondering if its possible to replace them with
new units, but leaving the sleeves, so I dont have to do much work in
carpentry.
Answer:
I'm sure it is possible but whether you'll be able to find *exact same
size* replacements is another question. You'll have to get the
sleeve's measurements and check the various manufacturer's web sites
for current model's specifications. Your best chance is likely finding
a current Friedrich model but other brands may also have similar
specifications.

Optionally you could remove the units you have an take them to a local
appliance repair shop and have them checked out. They might not have
serious problems to correct but will certainly need to be
professionally cleaned if it hasn't been done in the last 3 years. Air
conditioners should be professionally at least every 3 years (every
year if used in a high traffic area) to keep them working as well as
possible while using the least amount of energy.
