The hot and humid summers in Kearney, Nebraska, can get muggy and uncomfortable. You set the thermostat to a pleasant temperature. The air conditioning starts up automatically. But, even after your AC cycles, your home still feels damp and sticky.
That’s not very comfortable.
It can be disappointing when the air conditioner appears to work properly, yet your home doesn't actually feel very comfortable. If your rooms feel humid but thermostat says cool, you're not the only homeowner. It happens a lot.
The reason is simple: Temperature and humidity are two different things. Your temperature only tells you how comfortable the air is within the room. It doesn't measure the amount of moisture 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 blog, you'll learn how humidity affects your home 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 Kearney, Nebraska, home. That way, you’ll know when it’s time to call experts like the team at Thurston Heating & Air Conditioning for professional help.
Why Your Home Can Feel Humid Even If the Temperature Is Cool
Indoor temperature is only part of what makes your house comfortable. Humidity is another important element to consider. The majority of homes are typically more comfortable when indoor relative humidity stays between 30% and 50%. When a home has high indoor humidity, the air feels less comfortable, more oppressive and stickier—even if the actual air temperature is cool.
High humidity 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 chilling the air without pulling out enough moisture.
Home Feels Humid? Here are 8 Common Causes
Living in Kearney, Nebraska, high humidity can be a problem.
Many area homeowners deal with the same question: Why does my home feel so humid?
There are several common causes. Identifying what's creating humidity problems is a good first step toward solving the problem.
Below are several common reasons for elevated indoor humidity in Kearney, Nebraska:
1. AC is Too Large
An AC unit that's larger than your home actually needs lowers the temperature in your home too quickly. The problem is an oversized AC often doesn’t reduce humidity effectively because it stops operating before completing a proper cooling cycle.
2. Dirty Air Filter
A dirty air filter restricts airflow throughout your HVAC system. This makes it challenging for your equipment to extract humidity while cooling your home.
3. Obstructed Condensate Drain
Your AC removes moisture from the air in your home and drains it outside 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 extracts both heat and moisture from your home's air supply. Dirt buildup on the coil reduces its effectiveness and often requires professional AC repair services to fix.
5. Damaged Ductwork
Ductwork moves cool air throughout your home. Leaks in ductwork can allow warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This added moisture makes it more difficult to maintain comfortable humidity levels.
6. Thermostat Fan Set to “On” Change to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower keeps running after the cooling cycle ends. This can blow 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 extremely humid and hot summers, your HVAC system has to run longer to remove moisture from the air. Even when your air conditioning is working properly, sometimes your home feels muggy because outdoor humidity continually enters your home through doors, windows and normal air leakage.
8. Poorly Maintained Heating and Cooling Equipment
As heating and cooling systems wear out over time, they often become less efficient at controlling humidity. HVAC maintenance optimizes performance, improves efficiency and helps identify worn-out parts. Neglecting regular air conditioning maintenance can reduce 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 several simple things you can check before scheduling service. These strategies are easy ways to improve indoor comfort by helping your AC or heating system remove moisture more efficiently.
- Check your HVAC air filter. A clean heating and cooling system air filter allows proper airflow, helping your system cool and dehumidify your home effectively.
- Verify the thermostat fan is set to Auto. This allows moisture to flow out after each cooling cycle instead of being sent back into your living spaces.
- Check that supply and return vents are open and unblocked. Rugs or household furnishings over the vents or closed vents can limit airflow throughout your home.
- Check for water around the indoor unit. Water by your AC equipment may suggest a clogged condensate drain or another drainage issue.
- Monitor how your AC should run. If the AC is short cycling or turning on and off continuously, or it seems to run constantly without improving comfort, 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 system components. DIY repairs may be tempting, but these repairs require professional 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 with your HVAC system to manage humidity throughout your entire house.
Just one of Thurston Heating & Air Conditioning's indoor air quality solutions, a whole-home dehumidifier makes your home more comfortable while helping reduce the risk of mold, musty odors and excess moisture. It can be especially helpful for homes in damp climates or properties that still have humidity even with a properly functioning AC.
