How a Dehumidifier Can Make 75° Feel Like 65°
Picture this: A heat wave has just arrived, your thermostat reads 75°, but it feels hotter than that. You’re uncomfortable and wondering if something is wrong with your HVAC system.
One thing you might not know is that the temperature doesn’t tell the whole story. How hot we feel depends on both temperature AND humidity. Ever noticed the “feels like” temperature when you’re looking at the weather forecast? This is also known as the heat index.
High humidity makes the weather or your home feel warmer than it is, because it makes it more difficult for your body to cool itself through sweating. It also makes the air feel sticky and heavier.
Indoor Humidity 101
We’ve all experienced outdoor humidity, but you’re probably wondering what contributes to indoor humidity. First, know that it’s normal for your indoor humidity to read higher in the summer. Plus, things like cooking, taking showers, leaky ductwork, and drafty windows/doors all contribute to your home's humidity.
The Humidity Sweet Spot
The ideal range for indoor relative humidity is 40-50%. You’ll notice that 73° at 45% humidity feels a lot cooler than 73° at 65% humidity.
Not sure what your indoor relative humidity is? Check your thermostat. Most newer thermostats will tell you.
If your system is older, you can purchase an indoor hygrometer for a reasonable price online or at most hardware stores.
Whole-Home Dehumidifiers
If your system includes a whole-home humidifier or dehumidifier, it will also include a humidistat, which lets you control the humidity in your home. This feature also lets you raise the thermostat temperature while remaining comfortable. Comfort and a lower energy bill? It’s a win-win situation!
Did you know? Many new HVAC systems can natively prioritize humidity control. Ask your HVAC provider to learn more if you’re replacing your system soon!
Other Dehumidification Options
Even if you don’t own a whole-home dehumidifier, there are still ways to lower your humidity to make your home feel cooler.
You can try:
Running bathroom/kitchen exhaust fans more often
Set up a portable humidifier in the most humid spaces (these are often basements)
Change your fan setting to AUTO instead of ON. Continuously running the fan can cause moisture on the coil to evaporate and recirculate.
Make sure your exhaust fans and dryer vent pipe are venting outside.
