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.

How to Keep Your Indoor Air Clean When Wildfire Smoke Is in the Air

April 28, 2026

Wildfire season has become an increasingly common part of life in Southwest Montana, especially for homeowners in Bozeman, Belgrade, and Four Corners. While the smoky haze outside is easy to see, what’s happening inside your home is often less obvious. Many people assume that simply closing windows and doors will keep them safe—but wildfire smoke can still enter your home and impact your indoor air quality (IAQ) in ways that affect both comfort and health. Why Wildfire Smoke Indoors Is a Serious IAQ Concern Wildfire smoke is made up of extremely fine particles called PM2.5, which are small enough to pass through tiny openings and even some standard HVAC filters. Once inside your home, these particles can circulate through your ductwork and linger in the air. For homeowners in our area, poor indoor air quality during wildfire season can lead to: Coughing, sneezing, and throat irritation Headaches and fatigue Aggravated asthma or allergies Increased strain on your HVAC system Without proper filtration and system maintenance, your home’s air may not be as clean as you think. How Smoke Affects Your HVAC System Your HVAC system plays a major role in managing your indoor air quality —especially during wildfire events. When smoke enters your home, your system can either help remove harmful particles or unintentionally spread them throughout your space. If your system isn’t equipped with the right components, you may experience: Reduced filtration of fine smoke particles Dirty ductwork circulating contaminants Increased wear and tear on system components Decreased efficiency and airflow This is why homeowners across Bozeman and Belgrade are upgrading their systems to better handle wildfire smoke conditions. HVAC Solutions to Improve Indoor Air Quality During Wildfire Season The most effective way to protect your home’s air is through professional HVAC solutions designed specifically for indoor air quality in Four Corners, Belgrade, and Bozeman. Upgrade to HEPA or High-Efficiency Filters Standard filters aren’t designed to capture the smallest smoke particles. Upgrading to HEPA filters or high-MERV rated filters allows your system to trap significantly more airborne contaminants, improving your IAQ immediately. Install Whole-Home Air Purification Systems Advanced air purification systems integrate directly into your HVAC system to continuously clean the air as it circulates. These systems are especially effective during wildfire season when outdoor air quality is poor for extended periods. Add an Air Scrubber Air scrubbers go beyond traditional filtration by actively removing pollutants, odors, and particles from the air and surfaces in your home. This added layer of protection can make a noticeable difference in homes affected by wildfire smoke. Schedule Professional Duct Cleaning If smoke has entered your home, particles can settle inside your ductwork. Duct cleaning removes built-up contaminants and prevents them from being recirculated, helping restore cleaner air throughout your home. Keep Up with HVAC Tune-Ups Regular HVAC tune-ups ensure your system is running efficiently and filtering air properly. During wildfire season, a well-maintained system is critical for maintaining healthy indoor air quality. Long-Term Protection for Homes in Bozeman, Belgrade & Four Corners Wildfire smoke isn’t just a temporary inconvenience—it’s an ongoing challenge for homeowners in Southwest Montana. Investing in indoor air quality solutions through your HVAC system provides long-term protection for your home and your family. By combining: High-efficiency filtration Whole-home air purification Air scrubbers Clean ductwork Routine system maintenance …you can significantly reduce the impact of wildfire smoke indoors. Breathe Easier with the Right HVAC Support Your home should be a place where you can escape poor outdoor air—not bring it inside. With the right HVAC upgrades and maintenance, you can take control of your indoor air quality in Bozeman, Belgrade, and Four Corners, even during the peak of wildfire season. If you’re noticing smoke lingering in your home or want to prepare ahead of time, working with a trusted HVAC professional can help you choose the best solutions for cleaner, healthier air. Cleaner indoor air starts with the right system—and the right team behind it.
