Does Air Conditioning Reduce Humidity? Uncover the Facts!
Air conditioning is more than simply a cooling system (although that’s the most common thing that people think of when they hear the words). A common question is whether air conditioning decreases a room’s humidity level. The short answer is yes, the air unit does work to humidify the air. AC units not only cool the air but also remove the moisture, and that can make a huge difference in the comfort level of a space. That said, there are a number of factors that contribute to the ability of your AC unit to control humidity levels. This post will explore the question of “Does Air Conditioning Control Humidity?” in more detail, along with my own commentary, and share some of my recommendations to getting the most out of your AC unit. Understanding Humidity and Its Impact on Indoor Environments What is Humidity? Humidity is the measure of water vapor in the air. It’s often expressed in terms of relative humidity, which indicates how much moisture is currently in the air compared to how much moisture can be held in the air at that temperature. As a general expectation, the humidity in the house should be between 30% and 50%. When relative humidity is beyond, you will likely begin to notice the effects of high humidity in your environment. Conversely, when worth humidity is too low, the air will feel dry and uncomfortable. When humidity is above ideal range, that can contribute to a number of issues related to your health and home. For example, high humidity can provide ideal conditions for mold growth, damaging furniture, and making it more difficult to breathe. Effects of High Humidity Indoors When indoor humidity rises, the air feels warmer. Therefore, the AC has to work harder to make the environment feel comfortable. High humidity can have other consequences besides discomfort. A few of the most common issues are: Mold and Mildew: High humidity encourages the growth of mold, which can cause extensive damage to your home and affect your health, particularly for those suffering from respiratory problems. Health problems: Excess moisture in the air can worsen symptoms of allergies and asthma because but dust mites and mold thrive in this type of environment. Damage to Property: Moisture can warp wood, damage wall paper, and cause metals to rust, which can turn into expensive repairs. Managing humidity is not just about comfort, but also about keeping a healthy indoor environment. How Air Conditioning Affects Indoor Humidity Air Conditioning as a Dehumidifier While air conditioning is primarily designed to cool, it also has the added benefit of getting rid of heat. When warm, humid air travels over the evaporator coils in your AC unit, moisture condensation occurs some of the moisture is drawn out of the air as it is cooled in the coils. Because of this, the air conditioning process cools a room and removes moisture simultaneously. Most of the condensation that forms as water is either collected in a bucket or drained away from the unit or blown back into the air. As I can attest, air conditioning’s ability to remove moisture is more apparent in areas with humidity. You know the sticky and uncomfortable feeling that can occur on a hot summer day in the absence of humidity control? Using the air conditioner not only provides room cooling; it also removes humidity, making the air feel better in the process. Aircon and Humidity Control In terms of dehumidification, the type of air conditioner you have can affect how well it works. Most of the time, central air conditioning systems are better at controlling humidity in bigger areas, while window units or portable ACs work better in single rooms. Setting the humidity level in your air conditioner is very important because it keeps your home from getting too muggy, especially during the summer when the humidity outside is high. Having said that, it is important to remember that controlling humidity and air conditioning go hand in hand. If the air conditioner is too small for the room or isn’t working right, it might not be able to lower the humidity enough, leaving you with a stuffy space. In these situations, you might need extra help, like dehumidifiers or better air flow. Does Air Conditioning Dry the Air? People might wonder if air conditioning dries the air. There are a few more parts to the answer. Air fans take moisture out of the air; however, they are not supposed to dry it out too much. Dryness using air conditioning is typically limited to an aging air conditioning unit that has not been well maintained. If you think the air is dry after using the air conditioning, it may simply be the way the air is circulated, or the weather in your home. To resolve the dryness, you can flip the heater controls or use a humidifier. Air Conditioning vs. Humidifiers: Which is More Effective in Managing Humidity? Comparing Air Conditioners to Humidifiers Even though air conditioners and humidifiers may seem similar, their function is different. Air conditioners cool and eliminate moisture from the air to reduce humidity. Humidifiers add moisture to the air, which is helpful to control dryness. You will first want to utilize air conditioning and humidity control within a building, if you are concerned with reducing too much moisture. Otherwise, humidifiers can be useful for dry indoor air, especially in the winter season, to allow for additional water content to your comfort, but this would generally not be done in a more humid region. Air conditioning is better suited for controlling high humidity while the air conditioner helps keep the interior of your home warm. Factors That Affect Air Conditioning’s Ability to Remove Humidity Air Conditioner Type and Efficiency The type of air conditioner you have is very important in terms of how it handles humidity. For example, central air conditioners tend to be better at removing humidity in larger areas. Window units and portable air conditioners are great for
