my son came over the other day and replaced the old air conditioner in the lounge room. the difference is hard to comprehend. it works. it's lovely. it's also very quiet. i don't have to have the teev volume on 50 anymore and i should notice the difference in the power bill. we had a week of very high humidity and lots of rain last week along with a few storms, lovely if you are safe at home. before the storms there was not a breath of a breeze. still and heavy and hot. the last few days have been such a lovely relief, so nice and cool but it's early days yet and i expect lots more summer heat. at least i will be more comfortable now.
