Create An Automatic Pop-up Based On A Condition

I have an Excel file with multiple worksheets. 4 of these worksheets have the same format and have concatenate formulas in cells D14 through D28. What I need is an automatic pop-up message to tell me when I open the file if on any of these 4 worksheets text is generated from the concatenate formula that matches either "air cooling unit", "air heating unit", or "ceiling".

And, if so, I need for the pop-up to state the name of the Worksheet/tab and which of the above text strings match. For example, if one tab is named "6-5-09 C" and within the range of D14:D28 the text "ceiling" is listed, the pop-up should read something like, "Maintenance Needed for ceiling on 6-5-09 C!" If there are multiples on multiple worksheets, then I'd want all of them listed on the same pop-up. Then I would want to be able to click OK or CLOSE to close the pop-up. If I can even color the pop-up a color different than the regular gray, that'd be cool too.
