I work in Phoenix, but I live just east of the city in tempe. Tempe is a suburb of Phoenix. We basically share the Phoenix Sky Harbor International airport. The two cities are very close to each other. I make more money working in Phoenix, but I pay cheaper real estate taxes living outside of the city. I bought a house a couple of years ago. I never saw myself putting down roots in Phoenix, but I met a girl here while I was in college and she was from the area. She did not want to move East so I decided to stay in Phoenix. We bought a house outside of the city a couple of years ago. Last year was the first time that we really had to test the heating and cooling system. In Phoenix, the summer temperatures can reach more than 100°. It is not unusual for the weather to be very dry and hot. It was hard on the AC unit to keep the house cool. I realize that it might be necessary to get a second air conditioner for the house. The main parts of the house seem to be cool, but there are several areas towards the back bedrooms where it seems like the temperatures are at least seven or eight degrees warmer. When the summer temps were hot this summer, I decided to use a thermometer to check. If I put a ductless AC unit in the back of the house, it might be easier to control the indoor temperatures. It would also help the main system work more efficiently and less frequently.
