The humid summers in Jefferson, Wisconsin, can get muggy and uncomfortable. You adjust the thermostat to a pleasant temperature. The air conditioning kicks on right away. But, even after your air conditioner cycles, your home still feels humid and uncomfortable.
Not a great feeling.
It can be annoying 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 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 moisture levels are too high, your home can feel much hotter 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 simple troubleshooting steps you can try to reduce humidity in your Jefferson, Wisconsin, home. That way, you’ll know when it’s time to reach out to experts like the team at Pratt Brothers for support.
Why Your Home Can Feel Humid Even When the Temperature Is Right
The temperature is only part of what makes your living space pleasant. The amount of moisture in the air is an extremely important element to consider. Many homes are the most comfortable when indoor relative humidity stays between 30% and 50%. When a home has high indoor humidity, the air feels warmer, denser and stickier—even if the actual air temperature is cool.
Too much indoor moisture can also contribute to 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 chilling the air without extracting enough moisture.
Home Feels Humid? Here are 8 Common Causes
Residing in Jefferson, Wisconsin, muggy conditions can be a frequent concern.
Plenty of area homeowners ask the same question: Why does my home feel so humid?
There are several common causes. Identifying what's creating high idoor humidity is a good first step toward resolving the problem.
Let's look at several common reasons for elevated indoor humidity in Jefferson, Wisconsin:
1. Oversized Air Conditioning
An air conditioner that's bigger than your home needs lowers the temperature in your home too quickly. The problem is an oversized AC often doesn’t eliminate humidity effectively because it stops operating before completing a full cooling cycle.
2. Dirty Air Filter
A blocked air filter reduces airflow throughout your HVAC system. This makes it challenging for your equipment to extract humidity while cooling your home.
3. Clogged Condensate Drain
Your AC removes moisture from your indoor air and and then it drains from the equipment through a condensate line. If that drain becomes clogged, moisture can't exit the system properly, contributing to excess moisture indoors.
4. Frozen Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air. Dirt and grime on the coil reduces its effectiveness and often requires professional AC repair services to restore performance.
5. Loose Ductwork
Ductwork moves cool air throughout your living space. Openings in ductwork can pull warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This additional moisture makes it more challenging to maintain comfortable humidity throughout your home.
6. Thermostat Fan Running on “On” Change to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower continues to operate after the cooling cycle ends. 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 conditioner is operating correctly, sometimes your home feels muggy because outdoor humidity continually enters your home through doors, windows and normal air leakage.
8. Older HVAC Equipment
As HVAC systems get older, they often become less effective at controlling humidity. HVAC maintenance enhances performance, improves efficiency and helps detect worn-out parts. Putting off regular air conditioning maintenance can decrease performance, including your system's ability to remove moisture.
What You Can Check Before Contacting an HVAC Technician
If your house feels humid, there are some simple things you can check before scheduling service. These DIY tips are easy ways to improve indoor comfort by helping your heating and cooling system remove moisture more effectively.
- Replace or inspect the air filter. A clean HVAC air filter allows proper airflow, helping your system condition and dehumidify your home effectively.
- Make sure 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 reduce airflow throughout your home.
- Inspect for water around the indoor unit. Water around your AC equipment may signal a clogged condensate drain or another drainage-related issue.
- Pay attention to how your air conditioning should run. If the AC is short cycling or turning on and off repeatedly, 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 try repairs with refrigerant, electrical components or internal parts. Do-it-yourself fixes may be tempting, but these repairs require advanced training and should always be handled by 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 a good option. Compared with portable units that only remove humidity from one room or area, a whole-home dehumidifier works alongside your HVAC system to control humidity throughout your entire house.
Just one of Pratt Brothers's indoor air quality solutions, a whole-home dehumidifier makes your home more comfortable while reducing the risk of mold, musty odors and excess moisture. It can be a great choice for homes in damp climates or properties that still have humidity even with a properly functioning cooling system.
When You Need to Request HVAC Service
Ongoing HVAC humidity issues often trace back to an underlying problem that requires professional repair. The technicians at Pratt Brothers will inspect refrigerant charge, airflow, blower performance and evaporator coils to identify why your system isn't controlling humidity effectively.
