The warm summers in Mount Horeb, Wisconsin, can get muggy and uncomfortable. You set the thermostat to a comfortable temperature. The air conditioning kicks on automatically. But, even after your AC cycles, your home still feels moist and clammy.
Not a great feeling.
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 in good company. Many area homeowners have this problem.
Why? Temperature and humidity are two different factors in indoor comfort. Your temperature only tells you how warm or cool the air is within your home. It doesn't measure how much moisture is in the air. When humidity levels are very 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 indoor comfort levels, common reasons your home feels humid even when the temperature is correct and easy troubleshooting steps you can try to reduce humidity in your Mount Horeb, Wisconsin, home. That way, you’ll know when you should reach out to experts like the team at JW Brager Heating and Cooling for support.
Why Your Home Can Feel Humid Even Though the Temperature Is Right
The temperature is only part of what makes your house enjoyable. Humidity is an extremely important factor. Many homes are the most comfortable when indoor relative humidity is 30-50 percent. When a home has high indoor humidity, the air feels less comfortable, more oppressive and stickier—even if the actual air temperature is cool.
Excess moisture can also contribute to 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 cooling the air without extracting enough moisture.
Home Feels Humid? Here are 8 Common Causes
Making your home in Mount Horeb, Wisconsin, excess moisture can be a challenge.
Plenty of area homeowners ask the same question: Why does my home feel so humid?
There are several common causes. Determining what's creating humidity problems is the best place to start toward solving the problem.
Let's look at several common reasons for high indoor humidity levels in Mount Horeb, Wisconsin:
Oversized Air Conditioner
1. AC is Too Large
An AC unit that's bigger than your home needs cools down your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it turns off before completing a full cooling cycle.
2. Blocked Air Filter
A clogged air filter limits airflow throughout your heting and cooling system. This makes it more difficult for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioner collects moisture from the air in your home and drains it outside through a condensate line. If that drain becomes restricted, moisture can't leave the system properly, contributing to excess moisture indoors.
4. Icy Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's indoor air. Dirt and grime on the coil limits its effectiveness and often requires professional AC repair services to restore performance.
5. Leaky Ductwork
Ductwork moves 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 additional moisture makes it harder to maintain comfortable humidity conditions.
6. Thermostat Fan Set to “On” Switch to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower keeps running after the cooling cycle completes. This can circulate moisture collected on the evaporator coil back into your home instead of giving it time for it to drain away.
7. Unusually Humid Weather
During the area’s very humid and hot summers, your HVAC system has to operate more to remove moisture from the air. Even when your air conditioning 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. Poorly Maintained HVAC Equipment
As HVAC systems get older, they often become less effective at controlling humidity. HVAC maintenance improves performance, boosts efficiency and helps detect worn-out parts. Putting off regular air conditioning maintenance can decrease performance, including your system's ability to control moisture.
What You Can Check Before Scheduling an HVAC Technician
If your home feels humid, there are some 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.
- Replace or inspect the air filter. A clean heating and cooling system air filter allows proper airflow, helping your system cool and dehumidify your home more efficiently.
- Verify the thermostat fan is set to Auto. This allows moisture to drain away after each cooling cycle instead of being blown back into your living spaces.
- Check that supply and return vents are open and unobstructed. Rugs or household furnishings over the vents or closed vents can limit 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.
- Know how your air conditioner should run. If the AC is short cycling or turning on and off frequently, or it seems to run constantly without cooling your home, it's time to have the system inspected by a professional.
Even if your thermostat still says cool but house feels humid, do not perform repairs with refrigerant, electrical components or internal parts. Do-it-yourself fixes may be tempting, but these repairs require specialized training and should always be performed by a qualified HVAC technician.
Does Your Home Need a Whole-Home Dehumidifier?
If you have humidity in your house during summer or year-round moisture problems, a whole-home dehumidifier may be a good option. Compared with portable units that only help reduce moisture in one room or area, a whole-home dehumidifier works alongside your HVAC system to manage humidity throughout your entire house.
