HVAC cooling is also a humidity control

If you live in a region where the heat and humidity are a big deal then I’m sure you are as thankful as I am for modern HVAC.

  • I simply can’t begin to imagine just how difficult it had to have been to get through heat season 75 or 80 years ago.

I wonder if that stereotype of the southerner rocking in a chair under a fan during the heat of the day comes from that old reality. I simply can’t imagine getting a whole lot accomplished if I had to deal with that level of heat and humidity armed with a fan. My grandpa used to tell stories about how the community he lived in thought they were fancy because they had a swamp cooler. A swamp cooler is an evaporative cooler that mildly reduces the temperature indoors. However, it is nothing compared to the modern day HVAC heat pump. Plus, our heat pumps are doing more than simply cooling the air inside our homes. While the HVAC is cooling the air, it’s also balancing out the humidity. It’s just part of the process and we get that benefit automatically. The heat pump starts the cooling process by removing warm air energy from inside the house. It then exhausts that heat energy outside through the HVAC cabinet outside the house. Well, as it is doing this, it’s also removing big chunks of moisture along with that heat energy. That too is then exhausted outside. That leaves the house with a much more balanced humidity level. This also means that we have to deal with a lot less mold & mildew.
