Does a Dehumidifier Cool a Room? How Dehumidifiers Enhance AC Cooling


There's nothing worse than walking into your home on a hot summer day and immediately feeling like you just stepped into a sauna. The air is so thick and heavy, you can almost see the moisture hanging around. You crank up the AC, but it never quite seems to make the room feel comfortable. Does this sound familiar? 

If you find yourself constantly battling humidity indoors, you've probably wondered - will getting a dehumidifier help cool things down? While dehumidifiers don't directly lower the air temperature, they can make a huge difference in how cool the air feels. By removing excess moisture from the air, these nifty machines allow your AC to run more efficiently and provide better cooling power.

What Exactly is Humidity?

Before we get into how dehumidifiers work their magic, let's quickly cover what humidity is. Humidity refers to the amount of water vapor, or moisture in the air. The higher the humidity, the thicker and heavier the air feels.

Here's an example - think about how different 75°F feels on a crisp, dry day versus a muggy summer afternoon. On a dry day, 75° is pretty comfortable. But when it's humid out, that same 75°F can feel sweltering and sticky. That's because humid air makes it much harder for your body's sweat to evaporate and cool you down.

The EPA recommends keeping indoor humidity between 30% and 50% relative humidity. Humidity levels below 30% can lead to dry skin, static electricity, and other issues. Levels above 50% can encourage the growth of mold, mites, and other biological contaminants.

Not only is humid air super uncomfortable, but it also forces your air conditioner to work overtime. With all that excess moisture, the AC has to spend more energy dehumidifying the air before it can lower the temperature. This puts extra strain on the system and drives up your energy bills.

How Dehumidifiers Work

So, how exactly do dehumidifiers help combat this moisture madness? It's a pretty simple concept. A dehumidifier pulls in the humid air from your room and passes it over cold coils or a refrigerated surface. As the air cools, the moisture condenses into water droplets that get collected in a tank or drained away.

The now dehumidified, drier air gets released back into your room, feeling significantly cooler and lighter than the humid air that went in - even though the temperature reading is the same! With less moisture bogging it down, your body can cool itself more effectively through sweating and breathing.

This drier air also allows your air conditioner to run much more efficiently. Instead of wasting energy dehumidifying first, the AC can focus all its power on simply lowering the temperature. Most units can cool a room 6-8 degrees faster when humidity levels are in a comfortable range.

The Benefits Go Beyond Just Cooling

While improved cooling and comfort are the main draws of using a dehumidifier, these nifty machines offer some other great perks:

Energy Savings - By reducing humidity, dehumidifiers allow your AC to run up to 25% more efficiently. This can translate into hundreds of dollars in savings over the cooling season.

Prevents Moisture Damage -High humidity creates the perfect breeding ground for mold, mildew, and musty odors that can ruin your home and belongings. Dehumidifiers stop excess moisture before it starts.

Protects Wood & Valuables -Too much moisture can warp wood floors, cause paint/wallpaper to peel, and damage valuables like books or instruments. Maintaining proper humidity levels prevents this costly damage.

Healthier Indoor Air -Mold, dust mites, and other allergens thrive in humid environments. Dehumidifiers make it harder for these triggers to grow, improving indoor air quality.

Choosing the Right Dehumidifier

Choosing the appropriate size dehumidifier for your area is essential if you want to reap the maximum benefits from it. Factors like room square footage, humidity levels, climate, and any major moisture sources should all be considered.

As a general rule of thumb, it's better to get a dehumidifier rated for a slightly larger area than you need. This ensures it can effectively handle any extra moisture without constantly running on overdrive.

Some other key features to look for include:

1. Automatic humidistat control to maintain ideal humidity levels

2. Low-temperature operation for use in basements, garages, etc.

3. Automatic restart after power outages

4. Built-in pump for continuous drainage through a hose
