The Critical Role of Humidity in HVAC Systems
It’s important for humidity levels to be optimized in any indoor environment. Both too high and too low humidity can cause problems, not just for the people who use those spaces, but also for the buildings themselves.
Problems When Humidity Is Too High
High humidity can cause people to feel unpleasantly sticky, as sweat cannot evaporate easily from the skin. People not only feel too hot, but can even develop heat-related illnesses such as heat rash, heat stroke or muscle cramps. They’re also more likely to suffer from respiratory infections, as the bacteria and viruses that cause them multiply more easily in humid conditions.
High humidity promotes the growth of mold spores and dust mites. Allergens are more likely to be present at high concentrations in moist air, leading to allergic reactions in susceptible people. Levels of pollutants such as VOCs and ozone are also typically higher.
Humid environments often smell musty. Condensation forms on windows and sometimes even on walls, which can lead to damage to the building structure. It’s important to bring the humidity down to a normal level to protect the building and its occupants from harm.
Problems When Humidity Is Too Low
Low humidity can also cause bothersome physical symptoms, including irritation to the throat, eyes, nose and skin from exposure to dry hair. Some people also experience headaches, or a worsening of their asthma symptoms, as a result of spending too long in a low-humidity environment. Annoyingly, static electricity can build up on carpets in very dry rooms, leading to people experiencing static shocks while walking.
Dry air can also cause damage to wooden objects. The dry air can cause wooden floors, instruments and furniture to dry out and warp. The damage is especially bad if humidity levels rapidly change, swinging from very high to very low and back again. Restoring humidity levels to a moderate, constant level can help to protect these items.

“Just finished my 7 months of days under the HVAC/R program. I was thoroughly impressed with everything the school had to offer. Instructors were top notch. Plenty of material to get practice and sharpen your skills. The faculty was always willing to go above and beyond for it’s students and the campus overall was clean and organized. I enrolled with my brother-in-law, which was great for both of us. I’d encourage that if you’re debating on enrolling, set up a tour with the admissions office and take a tour. You’ll quickly realize why it was named a top trade school im the country. Had I the chance to do it again, I would in a heartbeat.”
