Why High Indoor Humidity Is a Problem in Mississippi Homes

Jimmy Smith • August 18, 2025

Humidity poses a variety of problems. Moisture can lead to property damage and mold growth. As mold starts to thrive, it releases spores into the indoor air supply. As people inhale those spores, they can experience worse asthma or allergy symptoms or develop other respiratory problems. 


To prevent the problems associated with high humidity, HVAC in Brandon, MS, can help.


The Deep South Has Hotter Summers

Along with the higher temperatures, in much of the south, you’ll find higher humidity levels as well. Your air conditioner doubles as a dehumidifier by drawing hot, moist air from your living spaces. 


You can maximize the effect with an annual AC tune-up. Your technician will reverse the wear and tear from the previous year. This maximizes the cooling and dehumidification performance of the system.


Storm Season Increases Moisture and Dampness

Heavy rainfall can cause leaks throughout the home or flooding around the foundation. While prompt home repairs are essential in combating the excess moisture and flooding, your HVAC technician can also help. 


They can offer solutions to boost air circulation throughout your living spaces. Improved air circulation will keep your indoor environment drier and cooler.


Home Designs Trap Heat and Moisture

Are you concerned about high humidity? HVAC in Brandon, MS, can offer ways to keep your crawl space or basement dry and cool. It’s not uncommon to install a dehumidifier in these areas of the home. 


Modern units have smart controls or automatic operation, so you won’t have to worry about wasting energy with constant operation. The dehumidifier will only operate when it detects heightened humidity.


Poorly Sized HVAC Systems Contribute to the Problem

You might think that installing an oversized air conditioner is the best solution, but this won’t work as well as you expect. An oversized unit will cool your living spaces rapidly before it has a chance to draw moisture and humidity from your home. 


It will also run shorter and more frequent cycles, increasing your energy waste without having any effect on indoor humidity.
