Warm weather arrives. Your AC starts running, but your home still feels sticky. Family members keep lowering the thermostat. Now, some rooms feel damp while others feel too cold. Meanwhile, energy bills increase.
This is a frequent issue during humid summers in Marshalltown, IA. Many homeowners assume the solution is lowering the temperature, but comfort depends on more than your home’s temperature. Humidity plays a major role in how your home feels.
Managing summer humidity in Marshalltown, IA, is often the key to improving indoor comfort. When indoor humidity gets too high, your instinct may be to make your cooling system work harder. But, that’s usually not the most effective solution. Understanding how to reduce indoor humidity in summer can help you be more comfortable without overworking your air conditioner.
How Humidity Makes Your Home Feel Hotter
Ever ask yourself, “Why does my house feel sticky?” It’s because your house has high humidity. Humidity is moisture in the air. When air is extremely humid, sweat evaporates more slowly, so you feel warmer than the actual temperature. This can create a muggy feeling inside your home. The air feels heavy, it can be hard to sleep and your home isn’t comfortable.
Most experts say ideal indoor humidity levels are between 30% and 50%. When humidity levels are higher, indoor humidity problems can develop.
How to Tell if Your Home Has Excess Humidity
Many homeowners don’t know humidity is the problem until it becomes a big issue.
Frequent high indoor humidity symptoms in Marshalltown, IA:
- Moisture on windows from condensation
- Musty smell in the house during summer
- Air in room feels damp or clammy
- Visible mold and mildew
- Uneven comfort
- Home feels humid with AC running
- Repeated thermostat adjustments
Why Turning Down the Thermostat Isn’t the Right Solution for Indoor Humidity
Turning down the thermostat may make your home cooler, but it does not solve humidity issues. Overcooling by running your AC hard can raise energy costs, create cold spots and put additional wear on your air conditioner. 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 isn’t a good way to solve the real issue: high 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 air conditioning systems remove moisture better than others.
A variable-speed air conditioner provides enhanced HVAC humidity control because it operates longer at lower speeds. Running longer allows the system to reduce humidity in your home while maintaining a comfortable indoor temperature.
Smart thermostat can also help. Many smart devices monitor humidity levels, providing more insight into your home’s comfort conditions.
AC maintenance plays a role as well. Annual AC tune-ups help improve performance, maintain efficiency and provide peak humidity control while reducing the risk of breakdowns.
Improper AC Sizing: Making Humidity Worse
An AC unit with much more cooling capacity than your home needs can actually lead to humidity problems. Because oversized systems cool a home very quickly, they often run in short cycles. The temperature drops, but the system doesn’t stay on long enough to remove enough moisture to make your home comfortable.
On the other hand, a properly sized AC cycles more effectively and provides better HVAC humidity control. This is just one of the reasons professional sizing is so important during AC installation.
Advantages of a Whole-Home Dehumidifier
Air conditioners remove some humidity, especially variable-speed air conditioners. However, a whole-home dehumidifier is often the most efficient and effective way to control moisture throughout your entire home.
A whole-home dehumidifier operates with your HVAC system to remove excess humidity during summer. Humidity-control systems can also help maintain comfortable moisture levels during dry winter months.
Benefits of whole-home humidity control:
- Removes excess moisture throughout the entire home
- Helps the home feel cooler at higher thermostat settings
- Supports healthier indoor air
- Helps reduce mold and mildew growth
- Protects wood floors and furniture in winter
- Reduces wear and tear on your AC
- Prevents musty smells in your house during summer
- Improves comfort and sleep quality
6 Strategies for Managing Summer Humidity
A whole-home humidity control system is the most effective solution reducing indoor humidity, but there are other ways 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.
- Change Air Filters Regularly
Blocked filters reduce airflow and reduce system performance. Clean filters help your AC remove humidity more effectively. - Turn on Bathroom and Kitchen Exhaust Fans
Everyday tasks like showering and cooking add moisture to your home. Exhaust fans help remove that humidity before it spreads. - Address Air Leaks
Small gaps around windows and doors allow humid outdoor air in your home. Repairing air leaks helps keep wet air out. - Plan Seasonal AC Maintenance
Professional AC maintenance enhances overall system performance, including humidity removal. - Keep Windows Shut When Humidity Is High
Opening windows during peak humidity can introduce large amounts of moisture into your home. - Look into Indoor Air Quality Enhancements
Indoor air quality solutions such as whole-home dehumidifiers and ventilation equipment are useful tools to create a healthier, more comfortable indoor environment.
