The humid summers in Moline, Illinois, can get muggy and uncomfortable. You set the thermostat to a pleasant temperature. The AC kicks on as expected. But, even after your air conditioner runs, your home still feels damp and sticky.
Not a great feeling.
It can be disappointing when the air conditioner appears to work properly, yet your home doesn't actually feel pleasant. If your rooms feel humid but thermostat says cool, you're not alone. Local homeowners often have this experience.
Why? Temperature and humidity are two different factors in indoor comfort. A temperature only tells you how comfortable the air is within the room. It doesn't measure how much moisture is in the air. When moisture levels are extremely high, your home can feel warmer than the thermostat indicates, due to indoor humidity problems.
In this blog, you'll learn how humidity affects your indoor comfort levels, common reasons your home feels humid even when the temperature is comfortable and simple troubleshooting steps you can try to reduce humidity in your Moline, Illinois, home. That way, you’ll know when to call experts like the team at Freed Heating & Air Conditioning for expert assistance.
Why Your Home Can Feel Humid Even When the Temperature Is Cool
Indoor temperature is only part of what makes your house pleasant. The amount of moisture in the air is an extremely important element to consider. The majority of homes are typically more comfortable when indoor relative humidity falls between 30% and 50%. When a home has high indoor humidity, the air feels hotter, more oppressive and stickier—even if the actual air temperature is cool.
Too much indoor moisture can also promote dangerous mold growth, mildew, bad smells 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.
8 Common Reasons Your Home Feels Humid
Making your home in Moline, Illinois, excess moisture can be a frequent concern.
Countless area homeowners wonder the same question: Why does my house feel humid?
There could be multiple reasons. Determining what's creating high idoor humidity is the best place to start toward fixing the problem.
Here are several common reasons for indoor humidity problems in Moline, Illinois:
1. Oversized Air Conditioner
An air conditioner 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 limits airflow throughout your HVAC system. This makes it challenging for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioner pulls out moisture from your indoor air and that excess water drains from the unit through a condensate line. If that drain becomes clogged, moisture can't leave the system properly, contributing to higher indoor humidity.
4. Icy Evaporator Coil
The evaporator coil extracts both heat and moisture from your home's air supply. Dirt buildup on the coil reduces its effectiveness and often requires professional AC repair services to restore performance.
5. Damaged Ductwork
Ductwork carries cool air throughout your home. Leaks in ductwork can pull warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This extra moisture makes it harder to maintain comfortable humidity levels.
6. Thermostat Fan Running on “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 letting it to drain away.
7. Unusually Humid Weather
During the area’s very humid summers, your HVAC system has to operate more to remove moisture from the air. Even when your air conditioner is functioning as designed, sometimes your home feels muggy because outdoor humidity continues to seep into your home through doors, windows and normal air leakage.
8. Older Heating and Cooling Equipment
As home comfort systems age, they often become less efficient at controlling humidity. HVAC maintenance improves performance, improves efficiency and helps find worn-out parts. Putting off regular air conditioning maintenance can reduce 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 strategies are easy ways to improve indoor comfort by helping your heating and cooling system remove moisture more efficiently.
- Replace or inspect the air filter. A clean HVAC air filter allows proper airflow, helping your system condition and dehumidify your home more efficiently.
- Confirm the thermostat fan is set to Auto. This allows moisture to flow out after each cooling cycle instead of being sent back into your living spaces.
- Check that supply and return vents are open and unblocked. Furniture over the vents or closed vents can restrict airflow throughout your home.
- Look for water around the indoor unit. Water around your AC equipment may signal a clogged condensate drain or another drainage issue.
- Monitor how your AC should run. If the AC is short cycling or turning on and off continuously, or it seems to run constantly without cooling your home like it should, it's time to have the system checked by a professional.
Even if your thermostat still says cool but house feels humid, do not perform repairs involving refrigerant, electrical components or internal parts. Handling these repairs yourself may be tempting, but these repairs require specialized training and should always be handled by a qualified HVAC technician.
Should You Get a Whole-Home Dehumidifier?
If you deal with humidity in your house during summer or year-round moisture problems, a whole-home dehumidifier may be worth considering.
