The humid summers in Mount Horeb, Wisconsin, can get muggy and uncomfortable. You change the thermostat to a pleasant temperature. The air conditioner begins running right away. But, even after your air conditioner runs, your home still feels moist and clammy.
Now, you’re cool and damp.
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. Many area homeowners have this problem.
Why? Temperature and humidity are two different measurements in your home. A temperature only tells you how warm or cool the air is within the room. It doesn't measure how much moisture is in the air. When indoor moisture is very 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 comfortable and basic troubleshooting steps you can try to reduce humidity in your Mount Horeb, Wisconsin, home. That way, you’ll know when it’s time to contact experts like the team at JW Brager Heating and Cooling for professional help.
Why a Home Can Feel Humid Even When the Temperature Is Nice and Cool
The temperature is only part of what makes your home enjoyable. Humidity is also an equally important element to consider. Most homes are typically more comfortable when indoor relative humidity falls 30-50 percent. 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, musty odors 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 pulling out enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Making your home in Mount Horeb, Wisconsin, muggy conditions can be a challenge.
Plenty of area homeowners ask the same question: Why does my house feel humid?
There are a variety of common explanations. Identifying what's creating excess humidity is a key first step toward resolving the problem.
Here are several common reasons for elevated indoor humidity in Mount Horeb, Wisconsin:
1. AC is Too Large
An AC that's bigger than your home needs cools your home too quickly. The problem is an oversized AC often doesn’t eliminate humidity effectively because it shuts off before completing a full cooling cycle.
2. Clogged Air Filter
A blocked air filter reduces airflow throughout your heting and cooling system. This makes it harder for your equipment to remove moisture while cooling your home.
3. Clogged Condensate Drain
Your air conditioning removes 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 drain from the system properly, contributing to increased humidity levels.
4. Frozen Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air supply. Dirt and grime on the coil limits its effectiveness and often requires professional AC repair services to restore performance.
5. Loose Ductwork
Ductwork carries cool air throughout your living space. Openings in ductwork can draw warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This extra moisture makes it more challenging to maintain comfortable humidity throughout your home.
6. Thermostat Fan is on “On” Setting Switch to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower continues running after the cooling cycle is finished. This can blow moisture collected on the evaporator coil back into your home instead of giving it time for it to drain away.
7. Exceptionally 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 operating correctly, sometimes your home feels muggy because outdoor humidity continually enters your home through doors, windows and normal air leakage.
8. Aging Heating and Cooling Equipment
As home comfort systems age, they often become less capable at controlling humidity. HVAC maintenance optimizes performance, increases efficiency and helps find worn-out parts. Neglecting regular air conditioning maintenance can reduce performance, including your system's ability to remove moisture.
Simple Checks to Make Before Contacting an HVAC Technician
If your home feels humid, there are some simple things you can check before requesting service. These DIY tips are easy ways to improve indoor comfort by helping your HVAC system remove moisture more efficiently.
- Check your HVAC air filter. A clean HVAC air filter allows proper airflow, helping your system circulate air through and dehumidify your home effectively.
- Make sure the thermostat fan is set to Auto. This allows moisture to leave the system 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. Rugs or furniture 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-related issue.
- 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 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 system components. DIY repairs may be tempting, but these repairs require advanced training and should always be performed by a qualified HVAC technician.
Could You Benefit from a Whole-Home Dehumidifier?
