Air Conditioner vs Dehumidifier: The Truth Behind Using Your AC for Humidity Control

Are you struggling with excess humidity in your home? It can be frustrating to constantly feel as though you’re swimming through the air, and it can even lead to health problems such as mold growth and respiratory issues. Luckily, there are solutions on the market that can help to combat this problem.

Two commonly used appliances are air conditioners and dehumidifiers. But what is the difference between the two? Can an AC be used as a dehumidifier? Let’s dive into the truth behind air conditioner vs. dehumidifier systems and how they can benefit you.

Air Conditioner vs. Dehumidifier Capabilities

When it comes to the battle of air conditioner vs. dehumidifier capabilities, it’s important to understand the differences between the two. While both air conditioners and dehumidifiers can remove moisture from the air, the way in which they go about it is different.

Air conditioners have the primary function of cooling air while simultaneously removing some of the moisture in the process. Air is pulled into the unit, passed over the evaporator coils, which causes the moisture to condense and drip off, and then the now-cooled air is circulated back into the room. Dehumidifiers, on the other hand, are specifically designed to remove moisture from the air; they do not cool the air.

Can an AC Be Used as a Dehumidifier?

Air conditioning systems have become an integral part of our lives, especially during the summers, when even the slightest increase in temperature can make it unbearable to be indoors. Of course, this time of year is also notorious for humidity. So, that begs the question: can an AC be used as a dehumidifier?

When it comes down to it, the answer to this question can be “yes” or “no.” As we briefly mentioned above, an AC can be used as a dehumidifier to a small extent in that it can remove some moisture from the air. However, it is not designed to be used solely as a dehumidifier. When an air conditioner is used to cool the air, the excess moisture is typically removed as a byproduct. This does not mean that running your AC unit non-stop will necessarily dehumidify your home to the appropriate levels.

Using an air conditioner to dehumidify your home can also lead to other issues, such as overcooling and wasting energy. When humidity levels are high, an air conditioner will have to work harder and longer to reach the desired temperature. In turn, this can lead to higher energy bills and excess wear and tear on your unit.

When to Use a Dehumidifier vs. Air Conditioner

If you are experiencing high humidity levels, it’s important to consider which appliance is best suited for your needs. While an air conditioner may provide some relief, it’s important to note that it is not specifically designed to remove moisture from the air. On the other hand, a dehumidifier is specifically designed for this purpose and can effectively remove moisture from your home, leading to better air quality and overall comfort.

House dehumidifiers work by pulling in moist air from the room, then passing it over a cold coil which causes the moisture to condense. The now-dry air is expelled back into the room. Some models even come with a built-in humidistat, allowing you to set a desired level of humidity, and the device will automatically turn on and off to maintain that level.

The Benefits of Using a Dehumidifier

Using a dehumidifier to remove excess moisture from your home can provide numerous benefits. First and foremost, reducing humidity levels can help to prevent the growth of mold and mildew, which can lead to serious health issues if left unchecked. A dehumidifier can also make your home feel more comfortable by reducing the stuffy, clammy feeling caused by high humidity.

Additionally, using a dehumidifier can help to improve the efficiency of your AC unit. When humidity levels are high, your air conditioner has to work harder to reach the desired temperature. By removing excess moisture with a dehumidifier, your AC unit can operate more efficiently, saving you money on energy bills in the long run.
