The humid summers in Lincoln, Nebraska, can get muggy and uncomfortable. You adjust the thermostat to a pleasant temperature. The air conditioner kicks on automatically. But, even after your air conditioner cycles, your home still feels moist and clammy.
That’s not very comfortable.
It can be frustrating 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 things. A temperature only tells you how hot or cold the air is within the room. It doesn't measure how much moisture is in the air. When moisture levels are very high, your home can feel much hotter than the thermostat indicates, due to indoor humidity problems.
In this blog, 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 Lincoln, Nebraska, home. That way, you’ll know when you should reach out to experts like the team at AW Heating & Air Conditioning for professional help.
Why a Home Can Feel Humid Even When the Temperature Is Right
Indoor temperature is only part of what makes your home enjoyable. The amount of moisture in the air is another important factor. The majority of homes are generally more comfortable when indoor relative humidity stays between 30% and 50%. When a home has high indoor humidity, the air feels hotter, denser and stickier—even if the actual air temperature is cool.
High humidity can also encourage 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.
Reasons Your Home Feels Humid Even with the AC Running
Making your home in Lincoln, Nebraska, high humidity can be a problem.
Many area homeowners wonder the same question: Why does my home feel so humid?
There are a variety of common explanations. Identifying what's creating excess moisture is the best place to start toward fixing the problem.
Let's look at several common reasons for elevated indoor humidity in Lincoln, Nebraska:
1. Oversized Air Conditioner
An AC that's too big for your home cools your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it turns off before completing a proper cooling cycle.
2. Blocked Air Filter
A dirty air filter restricts airflow throughout your heting and cooling system. This makes it more difficult for your equipment to extract humidity while cooling your home.
3. Clogged Condensate Drain
Your air conditioning removes moisture from your indoor air and and then it drains from the equipment through a condensate line. If that drain becomes blocked, moisture can't exit the system properly, contributing to higher indoor humidity.
4. Icy Evaporator Coil
The evaporator coil removes both heat and moisture from your home's air supply. 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 house. Openings in ductwork can pull warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This added moisture makes it more challenging to maintain comfortable humidity conditions.
6. Thermostat Fan Running on “On” Switch to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower keeps running after the cooling cycle ends. This can push moisture collected on the evaporator coil back into your home instead of allowing it to drain away.
7. Unusually Humid Weather
During the area’s extremely humid summer weather, your HVAC system has to work harder to remove moisture from the air. Even when your air conditioning is working properly, sometimes your home feels muggy because outdoor humidity keeps entering your home through doors, windows and normal air leakage.
8. Poorly Maintained Heating and Cooling Equipment
As home comfort systems get older, they often become less capable at controlling humidity. HVAC maintenance optimizes performance, boosts efficiency and helps identify worn-out parts. Putting off regular air conditioning maintenance can limit performance, including your system's ability to control moisture.
Simple Checks to Make Before Contacting an HVAC Technician
If your house feels humid, there are several simple things you can check before requesting service. These DIY tips 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 heating and cooling system air filter allows proper airflow, helping your system condition and dehumidify your home better.
- 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 unblocked. Rugs or furniture over the vents or closed vents can restrict airflow throughout your home.
- Look for water around the indoor unit. Water by your AC equipment may indicate 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 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 attempt repairs with refrigerant, electrical components or internal HVAC parts. DIY repairs may be tempting, but these repairs require professional training and should always be left to a qualified HVAC technician.
Could You Benefit from a Whole-Home Dehumidifier?
