Seven years ago, I bought an air conditioner from Wickes (Model
KC-94)
It is the type that is designed to be mounted in a window frame.
(Like
what most private houses have in Florida!) For the past four years,
I
haven't used it, but this year, needless to say, I neeeded to use
it.
It still works fine, but I am pretty sure it is not blowing as cold
as
it used to. Do air conditioners such as these need any maintenance,
such as fluid top-up, etc? The label says it uses R22 coolant.

Thank you,

Frank

The only home maintenance is to clean the filters. Regassing may be
needed, but is not really a diy job in the uk. In America small top
up cans of r22 are sold, but not here AFAIK.

I am afraid you need to call an aircon service place, best bet is to
collar someone in an aircon van and offer cash for them to check the
pressures and regas as needed.
