The warm summers in Greensburg, Indiana, can get muggy and uncomfortable. You set the thermostat to a comfortable temperature. The air conditioner starts up as expected. But, even after your cooling system runs, your home still feels damp and sticky.
Now, you’re cool and damp.
It can be annoying when the air conditioner seems to be doing its job, yet your home doesn't actually feel pleasant. If your rooms feel humid but thermostat says cool, you're not alone. Local homeowners often have this experience.
Why? Temperature and humidity are two different factors in indoor comfort. Your temperature only tells you how comfortable the air is within the space. It doesn't measure the amount of moisture in the air. When humidity 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 indoor comfort levels, common reasons your home feels humid even when the temperature is correct and basic troubleshooting steps you can try to reduce humidity in your Greensburg, Indiana, home. That way, you’ll know when it’s time to call experts like the team at Wallpe Heating & Cooling for professional help.
Why a Home Can Feel Humid Even If the Temperature Is Right
The temperature is only part of what makes your living space enjoyable. Humidity is also an equally 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 warmer, denser and stickier—even if the actual air temperature is cool.
Too much indoor moisture can also contribute to dangerous mold growth, mildew, unpleasant 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 pulling out enough moisture.
8 Common Reasons Your Home Feels Humid
Living in Greensburg, Indiana, muggy conditions can be a problem.
Plenty of area homeowners deal with the same question: What's making my house feel humid?
There are a variety of common explanations. Determining what's creating excess moisture is a good first step toward resolving the problem.
Below are several common reasons for indoor humidity problems in Greensburg, Indiana:
1. Oversized Air Conditioner
An AC that's too big for your home lowers the temperature in 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. Dirty Air Filter
A dirty air filter restricts airflow throughout your heting and cooling system. This makes it challenging for your equipment to control humidity while cooling your home.
3. Clogged Condensate Drain
Your air conditioner pulls out moisture from the air in your home and that excess water drains from the unit through a condensate line. If that drain becomes restricted, moisture can't leave the system properly, contributing to excess moisture indoors.
4. Frozen Evaporator Coil
The evaporator coil extracts 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 fix.
5. Loose Ductwork
Ductwork carries cool air throughout your living space. Gaps in ductwork can pull warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This additional moisture makes it more difficult to maintain comfortable humidity levels.
6. Thermostat Fan Set to “On” Change setting to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower continues running after the cooling cycle is finished. This can push 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 work harder to remove moisture from the air. Even when your AC is functioning as designed, 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 HVAC systems get older, they often become less capable at controlling humidity. HVAC maintenance optimizes performance, increases efficiency and helps identify worn-out parts. Neglecting 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 home 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 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.
- Confirm 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.
- Make sure supply and return vents are open and unblocked. Rugs or household furnishings over the vents or closed vents can limit airflow throughout your home.
- Look for water around the indoor unit. Water near your AC equipment may indicate a clogged condensate drain or another drainage issue.
- Pay attention to 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 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. Do-it-yourself fixes may be tempting, but these repairs require specialized training and should always be performed by a qualified HVAC technician.
