How Humidity Affects Home Comfort—And Costs You More

hot-fan-man-computerWhen it starts to get hot outside, nothing sounds better than splashing around in a nice, cool pool, or running through a sprinkler like you did when you were young. Water can help us to cool down—unless, surprisingly to some, it’s in the air.

Humidity levels tend to rise as temperatures do. Humidity refers to the amount of moisture, or water vapor, in the air. And even though it doesn’t actually affect the temperature, it can make the air feel a lot warmer than it is. In your home, it could be the reason you’re spending too much on air conditioning in Roswell, GA.

How Humidity Affects Your Comfort

The relative humidity at which most people feel comfortable is usually between 30% and 50%. When humidity exceeds this percentage, your body starts to feel warmer, regardless of the reading on the thermostat.

The way your body cools off naturally is through sweat. As sweat evaporates from your skin, you feel cooler. But with high levels of moisture in the air already, sweat cannot evaporate so easily—the vapor has little space to move to. And that’s why you feel so much warmer when it’s not a dry heat.

Can Air Conditioners Control Humidity?

Your air conditioner can help to control the humidity in the air. Inside of the system, there’s a coil called the evaporator coil. The evaporator coil is where refrigerant evaporates and absorbs heat as it moves through your indoor and outdoor units. As it does, the coil cools off immensely, and moisture in the air condenses on the coil—meaning there is less moisture in the air blowing back in your home.

Humidity levels do drop in most cases when you are using an air conditioner—but for a price. Air conditioning is not cheap (as you know) and it has to run for even longer and use even more energy when it dehumidifies. Your air conditioner runs over time to dehumidify and cool the home, and sometimes you don’t even need to change the temperature to feel comfortable.

Should You Add a Dehumidifier to Your Home?

Your air conditioner may not be the best solution to dehumidify your home. But you can add a dehumidifier into your HVAC equipment to lower moisture levels in the air and stay more comfortable, with many additional benefits.

  • Save Money – Of course, there is an initial investment involved with a whole-house dehumidifier. But when you run your dehumidifier, you may be able to shut off the AC system or raise the temperature and save money.
  • Protect Your AC System – You want to hold off on AC replacement for as long as possible. Adding a dehumidifier to your HVAC system can help reduce wear and tear on an AC and keep it around for longer.
  • Improve Indoor Air Quality – Lowering moisture levels in the home may help to prevent or reduce mold growth, which is a major part of why we recommend whole-house dehumidifier models over portable, point-of-use units.
