When my husband and I lived up north, we always turned the air conditioning off when we left the house.
We didn’t need to worry about it getting so suffocatingly hot that it was dangerous for our health if the air conditioning wasn’t on.
When we older, we wanted to move further south. Neither of us could handle the cold anymore, but we didn’t want to be so far south that the heat and humidity was all year round. We settled for a small that was close to the ocean, but still somewhere in between where our children lived. The first summer we spent in our new home, was a learning curve. Where we used to turn off the fans and air conditioning when we left the house, we now had to leave everything running. We learned this lesson early in our new home. We left to go shopping one afternoon. My husband turned off all the fans and lights, while turned the air conditioning off. We weren’t gone for over three hours, but that was more than enough for mold and mildew to form. I turned the fans on and my husband turned on the air conditioning. We could smell the humidity, heat, and mold in the air. We were lucky to get home when we did. My husband filled the sink with cold water and bleach and we wiped all the window sills, woodwork, and walls with the bleach solution. A couple more hours and we may have needed to have professional mold remediation. Our AC unit is now running 24/7.
