The hot and humid summers in Ellsworth, Wisconsin, can get muggy and uncomfortable. You set the thermostat to a pleasant temperature. The AC kicks on automatically. But, even after your air conditioner cycles, your home still feels humid and uncomfortable.
Now, you’re cool and damp.
It can be frustrating 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 the only homeowner. It happens a lot.
Why? Temperature and humidity are two different things. Your temperature only tells you how comfortable the air is within your home. It doesn't measure how much moisture is in the air. When indoor moisture is too high, your home can feel several degrees warmer than the thermostat indicates, due to indoor humidity problems.
In this article, you'll learn how humidity affects your comfort, common reasons your home feels humid even when the temperature is right and basic troubleshooting steps you can try to reduce humidity in your Ellsworth, Wisconsin, home. That way, you’ll know when it’s time to call experts like the team at Walter's-Eaton's Electric, Plumbing, Heating & AC for support.
Why Your Home Can Feel Humid Even When the Temperature Is Nice and Cool
The temperature is only part of what makes your living space comfortable. The amount of moisture in the air is another important element to consider. The majority of homes are the most comfortable when indoor relative humidity falls in the 30-50% range. When a home has high indoor humidity, the air feels hotter, more oppressive 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 extracting enough moisture.
8 Common Reasons Your Home Feels Humid
Residing in Ellsworth, Wisconsin, excess moisture can be a frequent concern.
Countless area homeowners wonder the same question: Why does my home feel so humid?
There are several common causes. Identifying what's creating high idoor humidity is a key first step toward solving the problem.
Let's look at several common reasons for indoor humidity problems in Ellsworth, Wisconsin:
1. AC is Too Large
An AC unit that's larger than your home actually needs cools down your home too quickly. The problem is an oversized AC often doesn’t reduce humidity effectively because it shuts off before completing a complete cooling cycle.
2. Blocked Air Filter
A clogged air filter restricts airflow throughout your heting and cooling system. This makes it challenging for your equipment to remove moisture while cooling your home.
3. Clogged Condensate Drain
Your AC removes moisture from your home’s air and and then it drains from the equipment through a condensate line. If that drain becomes blocked, moisture can't leave the system properly, contributing to increased humidity levels.
4. Frozen Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's indoor air. Ice formation or excessive dirt on the coil limits its effectiveness and often requires professional AC repair services to fix.
5. Leaky Ductwork
Ductwork moves cool air throughout your home. Gaps in ductwork can pull warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This additional moisture makes it more challenging to maintain comfortable humidity conditions.
6. Thermostat Fan is on “On” Setting Change to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower continues running after the cooling cycle completes. This can push moisture collected on the evaporator coil back into your home instead of letting it to drain away.
7. Extremely Humid Weather
During the area’s especially humid summer weather, your HVAC system has to run longer to remove moisture from the air. Even when your cooling system is working properly, sometimes your home feels muggy because outdoor humidity continues to seep into your home through doors, windows and normal air leakage.
8. Aging HVAC Equipment
As home comfort systems age, they often become less efficient at controlling humidity. HVAC maintenance optimizes performance, increases efficiency and helps detect worn-out parts. Neglecting regular air conditioning maintenance can decrease performance, including your system's ability to control moisture.
Things to Check Before Calling an HVAC Technician
If your home feels humid, there are a few simple things you can check before booking service. These simple troubleshooting steps are easy ways to improve indoor comfort by helping your AC or heating system remove moisture more effectively.
- Replace or inspect the air filter. A clean heating and cooling system air filter allows proper airflow, helping your system circulate air through 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 circulated 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.
- Check for water around the indoor unit. Water around your AC equipment may indicate a clogged condensate drain or another drain problem.
- Know how your air conditioner should run. If the AC is short cycling or turning on and off continuously, or it seems to run constantly without cooling your home, 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 with refrigerant, electrical components or internal parts. DIY repairs may be tempting, but these repairs require advanced training and should always be performed by a qualified HVAC technician.
