    Hi...

    Agreed, Sam. But perhaps a caveat for the OP, if I may?

    When you do try it in the store, only once. :)

    If you turn it off; then on again without a few minutes
    delay it will (and should) do exactly as the one you have
    now is.

    Take care.

  2. Hi!
    That is a good idea...but I differ with you on how long the unit needs to
    operate. Maybe some of them can come up to cooling nearly instantly, but the
    various units I've worked with over the years have required a few minutes to
    "get up to full speed" after having sat idle for a while.

    I don't know that age has to do with this effect...I've got a 30+ year old
    Coldspot dehumidifier and some nearly-new Frigidaire window A/C units, with
    plenty of things in between and all take a while to come up after having
    been stored.

    Ironically if the condenser is _very_ cool you get no pressure and hence no
    cooling. Once the condenser is hot the pressure builds up and you get the
    pressure differential required to provide cooling.

    Higher efficiency units take longer to cool the room down.
     
  5. Really? Do you know why this is?

    I doubt such a broad statement can be made.
     
  7. A BTU is a BTU. Since the coils in a high efficiency unit are more
    extensive, it may take a bit longer to get going but this really
    shouldn't affect the validity of a quick test.

    No they don't, the cooling time depends on the BTU capacity of the unit.
    Higher efficiency A/C units will generally be physically larger for a given
    BTU capacity so a higher efficiency unit of the same physical size as a
    lower efficiency unit will take longer to cool but if you go just by the BTU
    (or tonnage in which case 1 ton = 12,000 BTU) two units of the same spec
    will cool similarly.

    Either the compressor isn't running or the system has lost it's charge. Make
    sure you've got it set properly and if that's the case then return it for a
    new one.

    There was probably a pinhole leak in one of the soldered plumbing
    connections, it may have opened up during normal shipping. There's not much
    difference between brands of A/C units.
