The hot and humid summers in Columbus, Ohio, can get muggy and uncomfortable. You adjust the thermostat to a ideal temperature. The AC starts up automatically. But, even after your air conditioner cycles, your home still feels damp and sticky.
That’s not very comfortable.
It can be annoying 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. Many area homeowners have this problem.
Why? Temperature and humidity are two different measurements in your home. Your temperature only tells you how warm or cool the air is within the space. It doesn't measure how much moisture is in the air. When indoor moisture is 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 comfort, common reasons your home feels humid even when the temperature is correct and basic troubleshooting steps you can try to reduce humidity in your Columbus, Ohio, home. That way, you’ll know when you should reach out to experts like the team at Classic Air for support.
Why Your Home Can Feel Humid Even If the Temperature Is Cool
Your home's temperature is only part of what makes your living space pleasant. Humidity is also an equally important factor. The majority of homes are the most comfortable when indoor relative humidity falls 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.
Excess moisture 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 removing enough moisture.
Home Feels Humid? Here are 8 Common Causes
Living in Columbus, Ohio, excess moisture can be a challenge.
Plenty of area homeowners deal with the same question: Why does my home feel so humid?
There could be multiple reasons. Determining what's creating high idoor humidity is a good first step toward fixing the problem.
Let's look at several common reasons for indoor humidity problems in Columbus, Ohio:
Oversized Air Conditioning
1. AC is Too Large
An AC unit that's bigger than your home needs lowers the temperature in 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 clogged air filter limits airflow throughout your heting and cooling system. This makes it more difficult for your equipment to extract humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioning collects moisture from the air in your home and that excess water drains from the unit through a condensate line. If that drain becomes blocked, moisture can't exit the system properly, contributing to excess moisture indoors.
4. Icy Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air. Ice formation or excessive dirt on the coil reduces its effectiveness and often requires professional AC repair services to fix.
5. Damaged Ductwork
Ductwork carries cool air throughout your living space. Leaks in ductwork can allow warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This added moisture makes it more difficult to maintain comfortable humidity throughout your home.
6. Thermostat Fan is on “On” Setting Change to “Auto”
If your thermostat fan is set to "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. Extremely Humid Weather
During the area’s extremely humid summers, your HVAC system has to work harder to remove moisture from the air. Even when your air conditioner is functioning as designed, sometimes your home feels muggy because outdoor humidity continues to seep into your home through doors, windows and normal air leakage.
8. Aging HVAC Equipment
As heating and cooling systems age, they often become less efficient at controlling humidity. HVAC maintenance enhances performance, increases efficiency and helps identify worn-out parts. Skipping regular air conditioning maintenance can reduce performance, including your system's ability to reduce moisture.
What You Can Check Before Calling an HVAC Technician
If your home feels humid, there are some simple things you can check before scheduling service. These simple troubleshooting steps 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 cool and dehumidify your home more efficiently.
- Verify the thermostat fan is set to Auto. This allows moisture to flow out after each cooling cycle instead of being blown 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 around your AC equipment may signal a clogged condensate drain or another drainage issue.
- Pay attention to how your air conditioning should run. If the AC is short cycling or turning on and off repeatedly, 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 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 left to a qualified HVAC technician.
Does Your Home Need a Whole-Home Dehumidifier?
If you deal with humidity in your house during summer or year-round moisture problems, a whole-home dehumidifier may be a good option. Unlike portable units that only remove humidity from one room or area, a whole-home dehumidifier connects to your HVAC system to control humidity throughout your entire house.
