Difference between Air Conditioner and Dehumidifier

When it comes to staying comfortable in the summer, most people think of cooling options such as air conditioners and fans. However, a lesser-known option is dehumidifiers. In this blog post, we will explain some key differences between air conditioners and dehumidifiers. We hope this information helps you decide which appliance is best for you.

What is Air Conditioner?

Air conditioners are devices that remove heat from an enclosed space, making the space more comfortable to occupy. In warm climates, air conditioners are used to cool indoor spaces such as homes and offices; in cooler climates, they can be used to heat these spaces. Air conditioners work by circulating refrigerant gas through a system of coils. As the gas passes through the coils, it absorbs heat from the surrounding air and evaporates. This process lowers the temperature of the air inside the space, making it more comfortable to occupy.

What is Dehumidifier?

A dehumidifier is a device that is designed to remove excess moisture from the air, typically in order to prevent the growth of mold, mildew, and other unwanted microbes. Dehumidifiers work by pulling in air through an intake hose or fan and then passing it over a series of cold coils. As the air passes over these coils, water vapor in the air condenses on their surface, forming droplets that fall into a collection bucket or tray. Some dehumidifiers are also equipped with built-in humidistats that allow them to automatically control their own humidity levels. Dehumidifiers are commonly used in basements, bathrooms, attics, crawl spaces, kitchens, and other damp areas where excess moisture can pose a health risk. By controlling humidity levels and mitigating moisture buildup, dehumidifiers help to keep homes and businesses clean and healthy.

Difference between Air Conditioner and Dehumidifier

An air conditioner is typically used to cool down a room or building by removing excess heat from the air, whereas a dehumidifier does the opposite by regulating humidity levels. An air conditioner employs various methods for cooling, including compressing and condensing refrigerant gases, while a dehumidifier typically relies on evaporative technology. Additionally, an air conditioner involves complex components like fans and coils, while a dehumidifier consists of simple mechanisms such as dampers and filters. Overall, although both devices are designed to regulate temperature and humidity levels in order to improve comfort and indoor air quality, they accomplish this goal via different methods and structures.


So, what’s the difference between an air conditioner and a dehumidifier? Air conditioners cool the air by removing moisture while dehumidifiers remove moisture from the air to reduce humidity. If you are looking for an appliance that will lower both your cooling and heating costs, then you should buy an air conditioner. However, if you want to decrease your indoor humidity levels, then you should purchase a dehumidifier.
