Dry indoor air can make you and your family very uncomfortable. Low humidity levels create static and cause dry skin and nosebleeds. Raising the humidity level inside your home can relieve symptoms and make you more comfortable as outdoor temperatures climb. 


You're probably wondering, “Can I use an AC and a humidifier together?” and we understand the concern. The last thing you want is to waste electricity running both at once without seeing results. This post discusses the function of a humidifier and an air conditioner and when you should use both to increase your comfort levels.


Our qualified technicians at Premier Systems are the number one AC maintenance experts in Bozeman. Our technicians have the real-world experience necessary to identify all sorts of HVAC problems and repair damage quickly to keep your home comfortable.


The Purpose of a Humidifier


Home humidity levels vary greatly depending on the native climate where you live. Generally, you want to maintain a moisture level of less than 50% inside your home. Any higher and you run the risk of mold infestation.


If you live in a very dry climate, supplementing with a humidifier can help relieve symptoms like dry skin and dehydration.


You can choose from several types of humidifiers depending on your needs. For example, a portable humidifier works well to increase the moisture level in one room, but the rest of your home will still have dry air. 


If you need to create a consistent humidity level throughout your home, consider installing a whole-home humidifier. It works with your HVAC system to distribute humid air through the ductwork.


Functions of an Air Conditioner


Your air conditioner works to maintain a comfortable temperature inside your home, but that’s not all. Your air conditioner acts as a dehumidifier during its normal operation process.


Refrigerant flows through the evaporator coils, absorbing heat to create cool air for your home. It also absorbs moisture at the same time, resulting in dry air that gives you itchy skin and other problems. While absorbing moisture is a normal part of the cooling process, it’s not necessarily the best for your home. 


If you live in a humid climate, you likely benefit from the dehumidifying process of your air conditioner. High humidity levels can make the air inside your home feel thick and difficult to inhale. Sweat can’t evaporate in high humidity conditions, making you feel damp all day long.


Determining if You Should Use a Humidifier


If you wonder, “Can I use an AC and a humidifier together?” the answer depends on the humidity level in your home. It’s difficult to know your exact humidity level without any tools. A hygrometer is an inexpensive way to get an accurate day-to-day measurement of your home humidity level. 


A hygrometer detects humidity through a copper coil and indicates if the level is too high or too low. If the humidity level is less than 35%, your home could benefit from a humidifier. If it’s over 50%, hold off on adding humidity to avoid mold growth.


Another way to detect dry air is to pay attention to physical symptoms. If your lips feel unusually chapped, your skin rapidly absorbs lotion, and you get unexpected nosebleeds, you are likely suffering the effects of low humidity. 


Using Your Air Conditioner and a Humidifier


If you live in a dry climate, you will benefit from replenishing moisture with a humidifier. A hygrometer will help you keep an eye on the humidity level so it doesn’t go beyond 50%. By using both simultaneously, you will enjoy cool air without suffering the effects of air with too little humidity. 


Reliable HVAC Service in Bozeman


Your air conditioner removes humidity from the air during the cooling process. If you suffer from dry air inside your home, you could benefit from using a humidifier along with your air conditioner. A whole-home humidifier will maintain a consistent humidity level in every room without the hassle of moving a portable humidifier from room to room throughout the day.


If you would like to improve your indoor air quality, installing a UV light for your air conditioner will remove pollutants from the air to help you breathe easier.
