The warm summers in Alliance, Nebraska, can get muggy and uncomfortable. You set the thermostat to a ideal temperature. The AC starts up automatically. But, even after your AC cycles, your home still feels moist and clammy.
Now, you’re cool and damp.
It can be annoying when the air conditioner seems to operate normally, yet your home doesn't actually feel very comfortable. If your rooms feel humid but thermostat says cool, you're in good company. Local homeowners often have this experience.
Why? Temperature and humidity are two different factors in indoor comfort. A temperature only tells you how hot or cold the air is within your home. It doesn't measure how much humidity is in your home. When moisture levels are very high, your home can feel several degrees warmer 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 right and simple troubleshooting steps you can try to reduce humidity in your Alliance, Nebraska, home. That way, you’ll know when you should call experts like the team at Jack's Heating, Cooling, Stoves & Fireplaces for professional help.
Why Your Home Can Feel Humid Even If the Temperature Is Nice and Cool
Indoor temperature is only part of what makes your home pleasant. The amount of moisture in the air is also an equally important consideration. Many homes are typically more comfortable when indoor relative humidity stays in the 30-50% range. When a home has high indoor humidity, the air feels less comfortable, heavier 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 lowering the temperature of the air without pulling out enough moisture.
Home Feels Humid? Here are 8 Common Causes
Living in Alliance, Nebraska, excess moisture can be a problem.
Countless area homeowners ask the same question: Why does my house feel humid?
There are a variety of common explanations. Determining what's creating excess moisture is the best place to start toward fixing the problem.
Below are several common reasons for indoor humidity problems in Alliance, Nebraska:
AC is Too Large
1. Oversized Air Conditioner
An AC that's larger than your home actually needs cools your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it shuts off before completing a complete cooling cycle.
2. Clogged Air Filter
A blocked air filter limits airflow throughout your HVAC system. This makes it harder for your equipment to remove moisture while cooling your home.
3. Obstructed Condensate Drain
Your air conditioning removes moisture from the air in your home and that excess water drains from the unit through a condensate line. If that drain becomes clogged, moisture can't leave the system properly, contributing to increased humidity levels.
4. Icy Evaporator Coil
The evaporator coil removes both heat and moisture from your home's air supply. Dirt and grime on the coil reduces its effectiveness and often requires professional AC repair services to fix.
5. Loose Ductwork
Ductwork transports cool air throughout your home. Openings in ductwork can allow warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This added moisture makes it more difficult to maintain comfortable humidity conditions.
6. Thermostat Fan Running on “On” Change setting to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower continues running after the cooling cycle ends. This can push moisture collected on the evaporator coil back into your home instead of letting it to drain away.
7. Extremely Humid Weather
During the area’s extremely humid and hot summers, your HVAC system has to operate more to remove moisture from the air. Even when your air conditioning is functioning as designed, 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 heating and cooling systems age, they often become less efficient at controlling humidity. HVAC maintenance enhances performance, improves efficiency and helps find worn-out parts. Putting off regular air conditioning maintenance can reduce 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 a few 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 a dirty air filter. A clean HVAC air filter allows proper airflow, helping your system condition and dehumidify your home more efficiently.
- Verify the thermostat fan is set to Auto. This allows moisture to leave the system after each cooling cycle instead of being blown 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 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 drain problem.
- Know how your air conditioner should run. If the AC is short cycling or turning on and off repeatedly, 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 attempt repairs involving refrigerant, electrical components or internal parts. Handling these repairs yourself may be tempting, but these repairs require advanced training and should always be performed 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.
