Spring in Kansas Means More Than Just Rain
“April showers bring May flowers” — but in Olathe and across Johnson County, Kansas, they also bring something homeowners don’t always expect…
👉 Excess indoor humidity.
After weeks of thunderstorms and fluctuating temperatures, many homeowners start noticing:
- Sticky or damp air
- Musty smells
- Foggy windows
- Rooms that feel warmer than they should
At Jack Harrison Heating & Air Conditioning, we see a spike in calls every spring related to indoor air quality and humidity control — and for good reason. Too much moisture in your home can lead to discomfort, higher energy bills, and even mold growth.
Why Spring Humidity Is a Problem in Kansas Homes
Spring weather in Kansas creates the perfect storm for humidity issues:
- Frequent rain and storms
- Rapid temperature swings
- Homes sealed tight from winter
When warm, moist air enters your home and isn’t properly circulated or removed, it lingers — making your home feel uncomfortable and unhealthy.
Signs Your Home Has Too Much Humidity
If you’re noticing any of these, your home may have a humidity problem:
- Musty or damp odors
- Sticky air or “heavy” feeling rooms
- Condensation on windows
- Increased allergy symptoms
- Mold or mildew growth
Even if your AC is working, it may not be enough to fully manage humidity — especially during mild spring temperatures when it doesn’t run as often.
4 Ways to Control Humidity in Your Home
1. Run Your HVAC System Regularly
Your HVAC system helps remove moisture from the air as it runs. During spring, many homeowners don’t run their system enough — allowing humidity to build up.
💡 Tip: Use your fan setting or run your system periodically to keep air circulating.
2. Consider a Whole-Home Dehumidifier
If humidity is persistent, a whole-home dehumidifier can make a huge difference.
Benefits include:
- Improved comfort
- Reduced mold risk
- Better indoor air quality
- Less strain on your AC system
3. Watch for Leaks & Standing Water
Spring storms can lead to hidden moisture issues.
Check for:
- Basement or crawl space dampness
- Leaky pipes or fixtures
- Water pooling near your foundation
Even small amounts of moisture can impact your home’s humidity levels.
4. Keep Vents Open & Unblocked
Blocked vents restrict airflow, making it harder for your HVAC system to regulate temperature and humidity evenly throughout your home.
Make sure:
- Furniture isn’t covering vents
- All vents are open
- Airflow is consistent room-to-room
Why Humidity Control Matters
Controlling humidity isn’t just about comfort — it also helps:
- Protect your home from mold and damage
- Improve air quality
- Reduce strain on your HVAC system
- Lower energy costs
In fact, properly managed humidity can make your home feel cooler — meaning your AC doesn’t have to work as hard heading into summer.
