Does a Dehumidifier Help Your AC?

Go to Home

As a homeowner in the Southeast, particularly in Florida, you’re no stranger to humidity. Thick, heavy air can cling to you the moment you step outside, making even milder temperatures uncomfortable. If the humidity is high enough, it can also make its way into your home. While your air conditioner works hard to keep your space cool, it may struggle to tackle the excessive moisture in the air at times. As a result, you can start to experience that clammy feeling indoors, even with the AC running. 

Fortunately, adding a dehumidifier to the mix can help you take some of the load off your air conditioner. Let’s look at how AC units work in relation to dehumidifiers and the potential benefits of using these two systems together to combat humidity inside your home.  

How a Dehumidifier Works With Air Conditioning 

Air conditioners and dehumidifiers both work to reduce humidity, but they do so in slightly different ways. AC systems cool the air inside your home by transferring heat and humidity to the outdoors. The primary goal of an AC system is to lower the temperature in your space, and dehumidification is only a secondary effect. 

On the other hand, dehumidifiers are especially designed to remove moisture from the air. Warm air enters the dehumidifier and passes over cold coils, which cause the moisture to condense and drip into a collection tank or drain away. 

When the two systems work together, the dehumidifier takes on the burden that high humidity puts on your AC. That means your cooling system can work more efficiently, leaving you to enjoy reduced humidity levels and a more comfortable indoor temperature. 

The Role of Humidity on Indoor Comfort 

Humidity significantly influences how comfortable you feel indoors. Beyond the actual temperature, the amount of moisture in the air also affects our perception of warmth or coolness. Both high and low humidity levels can negatively impact your comfort and health, making it crucial to maintain the ideal range. 

High Humidity

High humidity produces muggy conditions that can make your indoor environment unbearable, even when the temperature is set at a comfortable level. When the air is full of moisture, sweat evaporates more slowly, making it more challenging for our bodies to cool down efficiently. As a result, we feel hotter and stickier, even if the actual temperature isn’t that high.

High humidity levels can also cause moisture and condensation to stick to surfaces, leading to water damage and potential mold growth. Over time, mold exposure can lead to allergic reactions and respiratory issues. 

Low Humidity 

Low humidity often occurs during winter when indoor air becomes dry. This low moisture can result in several issues, including dry skin and lips, irritated sinuses and overall discomfort.

The Ideal Range 

Finding the balance between high and low humidity is key to indoor comfort. According to the Environmental Protection Agency (EPA), the ideal range is between 30% and 50%. Within this range, your body can effectively regulate temperatures, making you more comfortable in your home.

How Dehumidifiers Enhance AC Performance

Air conditioners remove moisture from indoor air as part of the cooling process. Pairing your AC with a dehumidifier increases the cooling system’s performance and efficiency. By reducing humidity levels in your home, dehumidifiers help prevent excessive moisture from accumulating inside your air conditioning system and interfering with its working components. As a result, your AC can run more smoothly and experience less wear and tear from working too hard during Florida’s high-humidity seasons.  

When to Use a Dehumidifier With Air Conditioning

The impact of humidity on air conditioning performance can be negative. Your AC has to work a lot harder to maintain desired temperatures. Using a dehumidifier along with your AC can be particularly beneficial in certain situations. Here are some of the times you should consider using them together:

  • When humidity is high: If you live in an area with consistently high humidity, like the Southeast, a dehumidifier can help maintain a comfortable indoor environment. Your AC can especially use the extra support from a dehumidifier if it struggles to keep up with the humidity.
  • When you notice musty odors or mold growth: When humidity levels are too high in your home, you may notice musty odors or signs of mold. A dehumidifier can help your AC reduce moisture and prevent further growth.
  • When you have health concerns: If you or a loved one has asthma, allergies or other respiratory conditions, a dehumidifier can improve indoor air quality by maintaining a lower humidity level.
  • When the AC is oversized: An oversized air conditioner may cool the air in your home too quickly. While you might get the desired temperature, your AC won’t run long enough to effectively lower humidity. In that case, you will need a dehumidifier to balance the humidity levels. 

The Benefits of Using a Dehumidifier With AC

Installing a dehumidifier to help your AC offers a comprehensive approach to dealing with high humidity levels. Some of the benefits of using dehumidifiers with AC units include:

  • Improved comfort: Dehumidifiers work with your AC to lower humidity levels, making your home feel cooler and more comfortable even at higher temperatures. Lowering the moisture in the air also eliminates that sticky feeling often associated with high humidity.
  • Fewer allergens: Humidity can create a moist environment that’s a breeding ground for mold, mildew and dust mites. Installing dehumidifiers with your AC will inhibit their growth, reducing allergens and improving indoor air quality.
  • Energy savings: A dehumidifier reduces the workload on your AC. As a result, your air conditioner can cool your home more efficiently, using less energy to achieve the same level of comfort. 
  • Extended AC lifespan: A dehumidifier helps AC components experience less strain during the summer. Combining the two can prolong your AC’s lifespan and reduce the need for costly repairs. 
  • Home protection: Excess moisture and condensation can weaken your foundation, cause the paint on your walls to peel and damage your furniture. Dehumidifiers can help protect your house and belongings from the moisture damage caused by extreme humidity.
