Air Conditioner

We are going to get an air conditioner soon. It is going to cost a lot of money. I hope that this doesn’t come and bite us in the bum. I can see Suzannes point that she is going to be hot being at home, but I don’t think she can see my point of keeping the doors and windows closed during the day to keep the cool air in and the hot air out. She says you need “air flow”. I will admit, I don’t understand how flowing hot air through the house will help. The house was designed using passive solar priciples with the idea that you would not need an air conditioner. Indeed, there are neighbours of ours that do not have an aircon and they seem quite happy.
