When I went to visit my friends down south this past summer, I had no idea what I was getting into. I’ve been a northerner my whole life, so the hottest summer I’ve known was a warm day in July capped at the lower 80’s. To match that, it’s always a fairly low-humidity environment where I live and work. So, I wasn’t exactly prepared when I hopped off the plane and was greeted with a hundred-degree day in the dead of summer. To make matters worse, the humidity was incredibly high that day – it felt at least thirty degrees hotter than that! I was quick to walk through the concourse and find my friends at the front of the airport, and I prayed that their place had excellent air conditioning. Someone must’ve heard my prayers, because I walked into that house and it felt like a cozy day in the Fall back home! My friends told me that they spent a small fortune on renovating the entire heating, ventilation and air conditioning system from the ground up – literally, by installing radiant floors to provide heat in the winter. As for the cool, dry sensation in the air of their comfy home, they explained that was the result of their powerful central air conditioning system, which was complimented by a whole-house exhaust fan in the attic that could quickly draw all heat from the house in under an hour. To ensure the house stayed dry, they had a dehumidifier controlled by a humidistat, which worked to retain the perfect level of humidity. Not only did this allow them to keep the house cool and dry, but it allowed the central air conditioning system to work more efficiently. I’m definitely thankful for friends who see the value in long-term investments, as this trip would’ve been cut short if they lived in a hot, humid house!
