Suffering under a sweltering sun is not a good way to spend the summer. You enjoy the heat and long days of summer, and on especially hot days you may want to dip into the pool or make an excursion to the beach. But to sit in a hot and stuffy house is not your idea of fun. When you need a break from the heat, you should be able to go into your house and enjoy the coolness of the air conditioning. If your AC unit has broken down, you will not be able to.
