Will My Air Conditioning Work Better with Dehumidification?


Hot, muggy Florida summers usually mean homeowners crank up the AC and start to run dehumidifiers. But does running a dehumidifier add stress to your AC? Can operating a dehumidifier actually improve the performance of your air conditioner? Let’s take a look:

What is the Benefit of a Dehumidifier?

The humidity in northeast Florida can get intense. And when it does, it makes the hot temperatures feel even more unbearable. This is because higher humidity means more water vapor in the air, which means the air doesn’t evaporate as much sweat from your skin. When sweat evaporates, it carries some of your body heat away. Less evaporation equals hotter body temperatures.

In addition to making you feel hotter, humidity inside your home can make your house feel muggy, smell musty, damage your home’s structural integrity, and even attract pests like silverfish. Using a dehumidifier eliminates these problems because it works to evaporate the extra moisture in the air.

How Does a Dehumidifier Work?

A standard dehumidifier has four parts: a fan, a reheater, compressor coils, and a reservoir. The fan sucks in the air from your home, while a refrigerant gas cools down the compressor coils. These cooled coils collect the moisture from the air through condensation. Then, the extra moisture drips into the reservoir. The reheater serves to collect and release the heat given off during the dehumidification process.

The result is that the extra humidity from your home’s air is collected and disposed. All the while, heat is evacuated to the outside of the home. This means the inside of your home is cooler and dryer, leaving you feeling more comfortable and protecting your electronics from harmful humidity.

Does a Humidifier Make My AC More Efficient?

In the summertime, a humidifier helps your AC run more efficiently in a couple different ways. First, it removes the excess moisture from the air, which helps regulate the temperature. Second, the reheater component removes excess heat to the outside of the home. These two factors mean your AC will have less work to do in the hot summer months.

However, if you run a dehumidifier in the winter, your heater might have a little extra work to do, especially if you live in a well-insulated home. That’s because the extra heat generated by the dehumidifier will need to use more energy to evacuate the home, which means your heater will have to work a little extra to keep your indoor temperature regulated.

What's the Most Efficient Way to Use a Dehumidifier?

The most efficient way to use a dehumidifier is to use a thermostat with a humidity control in combination with a variable speed air handler. A variable speed air handler controls the speed of heated and cooled air with precision, which means higher efficiency, more control over zoning, and better air quality.  Combining this with a dehumidification thermostat will improve indoor air quality and allow for more efficient removal of humidity for the air in your home.
