The hot and humid summers in Moline, Illinois, can get muggy and uncomfortable. You set the thermostat to a pleasant temperature. The air conditioning kicks on right away. But, even after your AC runs, your home still feels humid and uncomfortable.
Now, you’re cool and damp.
It can be annoying when the air conditioner appears to work properly, yet your home doesn't actually feel comfortable. If your rooms feel humid but thermostat says cool, you're not the only homeowner. Many area homeowners have this problem.
Why is this? Temperature and humidity are two different things. A temperature only tells you how warm or cool the air is within your home. It doesn't measure how much humidity is in your home. When indoor moisture is too high, your home can feel much hotter than the thermostat indicates, due to indoor humidity problems.
In this guide, you'll learn how humidity affects your comfort, common reasons your home feels humid even when the temperature is correct and easy troubleshooting steps you can try to reduce humidity in your Moline, Illinois, home. That way, you’ll know when you should contact experts like the team at J.L. Brady Company LLC for professional help.
Why Your Home Can Feel Humid Even When the Temperature Is Nice and Cool
The temperature is only part of what makes your house enjoyable. The amount of moisture in the air is another important consideration. The majority of homes are typically more comfortable when indoor relative humidity stays in the 30-50% range. When a home has high indoor humidity, the air feels hotter, heavier and stickier—even if the actual air temperature is cool.
High humidity can also promote dangerous mold growth, mildew, unpleasant odors and other indoor air quality issues. That's why your house feels humid but the AC is running—your system may be chilling the air without pulling out enough moisture.
Home Feels Humid? Here are 8 Common Causes
Residing in Moline, Illinois, high humidity can be a challenge.
Countless area homeowners wonder the same question: What's making my house feel humid?
There are a variety of common explanations. Identifying what's creating excess moisture is a key first step toward resolving the problem.
Here are several common reasons for elevated indoor humidity in Moline, Illinois:
1. AC is Too Large
An AC unit that's too big for your home lowers the temperature in your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it stops operating before completing a proper cooling cycle.
2. Dirty Air Filter
A blocked air filter reduces airflow throughout your heting and cooling system. This makes it more difficult for your equipment to remove moisture while cooling your home.
3. Blocked Condensate Drain
Your air conditioning collects moisture from the air in your home and and then it drains from the equipment through a condensate line. If that drain becomes restricted, moisture can't leave the system properly, contributing to excess moisture indoors.
4. Dirty Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air. Dirt and grime on the coil limits its effectiveness and often requires professional AC repair services to fix.
5. Loose Ductwork
Ductwork transports cool air throughout your home. Gaps in ductwork can draw warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This additional moisture makes it more difficult to maintain comfortable humidity conditions.
6. Thermostat Fan Set to “On” Change to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower continues running after the cooling cycle ends. This can push moisture collected on the evaporator coil back into your home instead of allowing it to drain away.
7. Extremely Humid Weather
During the area’s very humid summer weather, your HVAC system has to run longer to remove moisture from the air. Even when your AC is working properly, sometimes your home feels muggy because outdoor humidity keeps entering your home through doors, windows and normal air leakage.
8. Poorly Maintained Heating and Cooling Equipment
As heating and cooling systems wear out over time, they often become less effective at controlling humidity. HVAC maintenance enhances performance, increases efficiency and helps identify worn-out parts. Neglecting regular air conditioning maintenance can limit performance, including your system's ability to remove moisture.
What You Can Check Before Calling an HVAC Technician
If your home feels humid, there are several simple things you can check before booking service. These simple troubleshooting steps are easy ways to improve indoor comfort by helping your HVAC system remove moisture more efficiently.
- Check your HVAC air filter. A clean heating and cooling system air filter allows proper airflow, helping your system cool and dehumidify your home effectively.
- Verify the thermostat fan is set to Auto. This allows moisture to drain away after each cooling cycle instead of being circulated back into your living spaces.
- Check to ensure your supply and return vents are open and unobstructed. Furniture over the vents or closed vents can limit airflow throughout your home.
- Inspect for water around the indoor unit. Water by your AC equipment may signal a clogged condensate drain or another drain problem.
- Know how your air conditioning should run. If the AC is short cycling or turning on and off frequently, or it seems to run constantly without cooling your home like it should, it's time to have the system evaluated by a professional.
Even if your thermostat still says cool but house feels humid, do not try repairs involving refrigerant, electrical components or internal HVAC parts. DIY repairs may be tempting, but these repairs require professional training and should always be left to a qualified HVAC technician.
Should You Get a Whole-Home Dehumidifier?
If you struggle with humidity in your house during summer or year-round moisture problems, a whole-home dehumidifier may be worth considering.
