A week after it started, we finally resolved the air conditioning situation.  You will recall that we moved the unit from bedroom A to bedroom B because it was a bit too loud for Tawn.  But the replacement installed into bedroom A stopped working after exactly one night.  Since the owner of the air conditioning company was out of town on a New Zealand holiday, we had to wait for his return to do anything more than have the new unit and compressor removed.

Instead of replacing the Panasonic unit that lasted only one night with another Panasonic unit, the decision was made to return to the same Mitsubishi model that we originally had installed in bedroom A - the one that we removed because it makes too much noise. 

According to the sales person, the noise issue was because of how it was installed and isn't related to the machine itself.  That may be true, since I work in bedroom B and haven't heard any noises when running the Mitsubishi until throughout the week.

In any case, this should help lower our electricity bill next month, since for the past week we had the main living room air con running all night and used fans to blow the cool air into bedroom A.

Check that off the list!
