How Humidity Affects Your Heating and Air System

Air conditioningIn the southeast, humidity is a serious problem. Not only can it put a damper on your summer, but it can also affect your health. Your cooling and heating system in Milton, GA, can help. Learn more here from the professionals at Cool Air Mechanical.

Comfort Controls

Humidity is the measurement of moisture in the air. Humidity levels are especially high in the summer after it rains. Water evaporates under the heat of the sun, increasing the levels of water vapor in the air. Water vapor makes the air feel heavy and damp. People with respiratory problems often find it harder to breathe when humidity levels are high. When humidity is high inside your home, you feel warmer and your body responds by sweating more. Humidity levels between 30% and 50% are considered comfortable by most people. Turning down your thermostats help lower the humidity level, but it’s impossible to remove all the moisture inside your home. Also, turning down the temperature will force your HVAC unit to work harder and drive up your electric bill.

The Evaporator Coil

When your AC is working properly, air is pulled through the return vents inside your home then forced into the evaporator coil. For central air systems, the evaporator coil is usually located in the inside AC unit either in your garage or AC closet. Inside the coils, a refrigerant is used to remove heat from the recycled air. As moisture evaporates, the air condenses, making it colder before sending it back into your home. The evaporator coil is one of the hardest working parts inside your unit. If you experience high levels of humidity even after turning down the thermostat, there could be a problem with either the coil or the condenser in the outside unit.

Mold Growth

moldMold loves dark, damp places like basements, bathrooms, and closets. High levels of humidity create the perfect environment for mold to fester. Once airborne, mold can affect your respiratory health. Coughing, sneezing, migraines, and difficulty breathing could be signs of a mold infestation inside your home. Extended exposure can lead to respiratory illnesses like COPD. Therefore, it’s important to maintain the right levels of humidity in your home. Before leaving for vacation, many people will turn off their AC or set it to a higher temperature. When they return home, they’re greeted by a musty odor and sometimes black growth on their furniture and walls. The conditions were perfect for mold to move in. If you’re going to be away from your home for an extended period, set your thermostat around 80 degrees before closing the house. The steady circulation of air will help prevent mold from manifesting while you’re away.

With adequate heating and air in Milton, GA, you can keep your home and your family cool this summer. For more tips to help fight humidity, contact the experts at Cool Air Mechanical.
