Does Humidity Affect My Utility Bills in the Summer?

Chris Helms - Thursday, July 30, 2015
Utility Bills and Pen

Energy efficiency is a common term that’s often thrown around without any real understanding of what impacts it. Most of us know that updated HVAC equipment and thoughtful use can increase the energy efficiency of our homes, but what about other factors, such as humidity? Most people don’t know that humidity can affect their energy use and also their utility bills. Keep reading for the information you need to know.

Humidity and You

Humidity is a way to measure the amount of water vapor in the air at any given time. During the hot, humid summer months we feel that moisture when we’re outside. It makes us feel hotter than we might in drier air because it prevents our bodies from cooling properly because it reduces the rate of evaporation of moisture from our skin. That’s why it’s not the heat, it’s the humidity.

Humidity and Your Utility Bills

When the relative humidity inside your home exceeds recommended levels (between 40% and 50%) your home feels warmer than it is. What do we do? We turn up the air conditioner. How does this affect our energy efficiency? Well, of course, we use more energy when we run the AC more, so it makes our homes less efficient.

Another thing about too much humidity in our homes is that it makes our air conditioning units less effective as well as less efficient. Even when we crank up the AC, we still don’t feel as cool as we would if the air was drier. As we use our air conditioning systems more, and we consume more energy, our utility bills go up and up. It’s a vicious cycle.

Reducing the relative humidity levels in your home is a key way you can work to increase energy efficiency and decrease your utility bills.
