Anyone done anything like whole house DIY-ish air con ?
For example, air con unit in loft (meaty one), vents in roof,
DIY ducting around house, to air condition the main rooms of the house.
It strikes me this might be easier than those through-the-wall units in
one or two rooms. Bung a duct down unused chimney breast etc. Might
need booster pumps due to large ducting lengths. Any thoughts ?
