I think Carrier is not Egyptian made, Miraco Carrier is. Is the label on the switch or the split itself? Please check this out.

Back home I have POWER air conditions installed in my apartment, made in Egypt. We've been using the same brand over the past 10 years. Every other summer we have them cleaned. They're good heavy duty.

I hope the problems will be solved before summer heated time.
