The humid summers in Columbus, Ohio, can get muggy and uncomfortable. You set the thermostat to a comfortable temperature. The AC begins running as expected. But, even after your cooling system cycles, your home still feels moist and clammy.
Not a great feeling.
It can be frustrating 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 in good company. Many area homeowners have this problem.
Why? Temperature and humidity are two different measurements in your home. A temperature only tells you how comfortable the air is within the space. It doesn't measure how much humidity is in your home. When indoor moisture is extremely 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 comfortable and basic troubleshooting steps you can try to reduce humidity in your Columbus, Ohio, home. That way, you’ll know when to call experts like the team at Classic Air for expert assistance.
Why Your Home Can Feel Humid Even Though the Temperature Is Cool
Your home's temperature is only part of what makes your home enjoyable. Indoor humidity is an extremely important element to consider. Many homes are typically more comfortable when indoor relative humidity is 30-50 percent. When a home has high indoor humidity, the air feels hotter, 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.
Home Feels Humid? Here are 8 Common Causes
Residing in Columbus, Ohio, excess moisture can be a problem.
Countless area homeowners deal with the same question: Why does my home feel so humid?
There are several common causes. Determining what's creating excess moisture is a key first step toward solving the problem.
Here are several common reasons for elevated indoor humidity in Columbus, Ohio:
1. Oversized Air Conditioner
An AC that's bigger than your home needs cools your home too quickly. The problem is an oversized AC often doesn’t reduce humidity effectively because it turns off before completing a proper cooling cycle.
2. Dirty Air Filter
A dirty air filter limits airflow throughout your HVAC system. This makes it harder for your equipment to control humidity while cooling your home.
3. Blocked Condensate Drain
Your air conditioning collects moisture from your indoor air and that excess water drains from the unit through a condensate line. If that drain becomes blocked, moisture can't leave the system properly, contributing to increased humidity levels.
4. Dirty Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air. Ice formation or excessive dirt on the coil decreases its effectiveness and often requires professional AC repair services to restore performance.
5. Leaky Ductwork
Ductwork carries cool air throughout your house. Leaks in ductwork can pull warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This extra moisture makes it more challenging to maintain comfortable humidity levels.
6. Thermostat Fan Set to “On” Switch 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 giving it time for it to drain away.
7. Exceptionally 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 conditioner is working properly, sometimes your home feels muggy because outdoor humidity keeps entering your home through doors, windows and normal air leakage.
8. Aging Heating and Cooling Equipment
As HVAC systems get older, they often become less efficient at controlling humidity. HVAC maintenance optimizes performance, boosts efficiency and helps detect worn-out parts. Skipping regular air conditioning maintenance can limit performance, including your system's ability to reduce moisture.
What You Can Check Before Contacting an HVAC Technician
If your home feels humid, there are a few simple things you can check before requesting service. These strategies are easy ways to improve indoor comfort by helping your heating and cooling system remove moisture more effectively.
- Replace a dirty air filter. A clean heating and cooling system air filter allows proper airflow, helping your system cool and dehumidify your home better.
- Make sure 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.
- Check that supply and return vents are open and not covered up. Rugs or furniture 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 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 frequently, 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 internal HVAC parts. Handling these repairs yourself may be tempting, but these repairs require advanced training and should always be performed by a qualified HVAC technician.
Could You Benefit from a Whole-Home Dehumidifier?
