    How do I calculate the a/c unit output when purchasing a reverse cycle a/c.
    Is there a formula?

    But be careful.

    The calculator linked above does not take into account high ceilings, cathedral ceilings etc.

    Incorrect - you will pay more for a unit which will do the same job as a smaller unit (more often than not).

    Call a couple of quotes, get them to size the unit appropriately and make your judgement call. Run through the details with the contractor so you know what you are getting.

    I recently installed several splits off two FCUs. Different contractors sized the equipment differently with similar outcomes (different brands)
