Summer arrives. Your air conditioner starts running, but your home still feels clammy. Family members keep turning down the thermostat. Now, some rooms are still uncomfortably humid while others feel too cold. Meanwhile, energy bills climb.

This is a typical challenge during humid summers in Marshalltown, IA. Many homeowners think they can fix it by lowering the temperature, but comfort depends on more than the air temperature. Humidity plays a big part in how your home feels.

Managing summer humidity in Marshalltown, IA, is often the key to creating a more comfortable home. When indoor humidity gets too high, your instinct may be to run your AC harder. However, that’s usually not the best solution. Knowing how to reduce indoor humidity in summer can help improve comfort while reducing strain on your air conditioner.

Why Excess Humidity Makes Your Home Feel Less Comfortable

Have you ever wondered, “Why does my house feel sticky?” It’s high humidity levels. Humidity is water vapor in the air. When moisture levels are high, sweat evaporates more slowly, which often makes you feel warmer than the actual temperature. This can create a damp and uncomfortable home. The air feels heavier, you may have trouble sleeping and your home isn’t comfortable.

Most experts say ideal indoor humidity levels range between 30% and 50%. When humidity levels are higher, indoor humidity problems can quickly form.

How to Tell if Your Home Has High Humidity

Many homeowners don’t realize humidity is the problem until they start to see issues around their house.

Frequent high indoor humidity symptoms in Marshalltown, IA:

  • Moisture on windows from condensation
  • Musty smell in the house during summer
  • Damp-feeling rooms
  • Visible mold and mildew
  • Some rooms are comfortable and others are not
  • Home feels humid with AC running
  • Repeated thermostat adjustments

Why Constantly Lowering the Thermostat Isn’t the Best Solution for Indoor Humidity

Turning down the thermostat may make your home feel cooler, but it doesn’t solve humidity issues. Overcooling by running your AC hard can raise energy costs, create cold spots and shorten the lifespan of your cooling system. Often, running your AC hard leaves you with a cold, still-humid home.

While your AC can remove some moisture from your home, they are primarily designed to provide cooling. That’s why lowering the thermostat doesn’t fix the real issue: excess humidity.

How HVAC Systems Help Control Humidity

As your air conditioner cools your Marshalltown home, it also reduces indoor moisture. Warm indoor air flows over the cooling coil, causing water vapor to condense and drain away.

Some AC units control humidity better than others.

A variable-speed air conditioner often provides better HVAC humidity control because it runs longer at lower speeds. Running longer allows the system to remove more moisture from the air while maintaining a comfortable indoor temperature.

Smart thermostat provide additional benefits. Many models monitor humidity levels, providing more insight into your home’s comfort conditions.

Routine maintenance is also important. Annual AC tune-ups help improve performance, maintain efficiency and support humidity control while reducing the risk of breakdowns.

Improper AC Sizing: Making Humidity Worse

An AC unit that’s too big for your home can actually cause moisture issues. Because oversized systems cool a home very quickly, they tend to run in short cycles. They quickly lower the temperature in your home, but the system doesn’t stay on long enough to remove enough moisture to make your home comfortable.

In contrast, a properly sized AC operates longer and provides better HVAC humidity control. This is just one of the reasons professional sizing is so important during new air conditioning installation.

Advantages of a Whole-Home Dehumidifier

AC units remove some humidity, especially variable-speed air conditioners. However, a whole-home dehumidifier is often the most effective way to control moisture throughout your entire home.

A whole-home dehumidifier operates with your HVAC system to remove excess humidity during hot, muggy summer weather. Then, during the cold months, whole-home humidity control systems add moisture to dry, uncomfortable winter air.

How a whole-home humidity control system increases home comfort:

  • Reduces humidity throughout the home
  • Helps the home feel cooler at higher thermostat settings
  • Enhances indoor air quality
  • Reduces mold and mildew risk
  • Protects wood floors and furniture in winter
  • Minimizes stress on your air conditioner
  • Prevents musty smells in your house during summer
  • Improves comfort and sleep quality

6 Tips for Managing Summer Humidity

A whole-home humidity control system is the most effective solution reducing indoor humidity, but there are other things you can do to improve comfort. If you’re wondering how to keep your house comfortable in humid weather, following this list of summer humidity tips can help.

  1. Keep Air Filters Clean
    Clogged filters limit airflow and reduce system performance. Fresh filters allow your AC remove humidity more effectively.
  2. Turn on Bathroom and Kitchen Exhaust Fans
    Bathing, cooking and routine household activities add moisture to your home. Exhaust fans help remove that humidity before it spreads.
  3. Stop Air Leaks
    Small gaps around windows and doors let humid outdoor air inside. Closing those gaps helps keep wet air out.
  4. Plan Seasonal AC Maintenance
    Routine AC maintenance helps overall system performance, including humidity removal.
  5. Avoid Opening Windows During Humid Conditions
    Opening windows during peak humidity can introduce large amounts of moisture into your home.
  6. Look into Indoor Air Quality Enhancements
    Indoor air quality solutions such as whole-home dehumidifiers/humidifiers and ventilation equipment are useful tools to create a healthier, more comfortable indoor environment.
