The hot and humid summers in Columbia, Mississippi, can get muggy and uncomfortable. You adjust the thermostat to a comfortable temperature. The air conditioning begins running right away. But, even after your AC runs, your home still feels moist and clammy.
Now, you’re cool and damp.
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 in good company. Many area homeowners have this problem.
The reason is simple: Temperature and humidity are two different factors in indoor comfort. The temperature only tells you how comfortable the air is within your home. It doesn't measure how much moisture is in the air. When indoor moisture is very high, your home can feel much hotter than the thermostat indicates, due to indoor humidity problems.
In this blog, you'll learn how humidity affects your indoor comfort levels, common reasons your home feels humid even when the temperature is comfortable and easy troubleshooting steps you can try to reduce humidity in your Columbia, Mississippi, home. That way, you’ll know when to contact experts like the team at Watts Electric & AC for professional help.
Why Your Home Can Feel Humid Even Though the Temperature Is Cool
Your home's temperature is only part of what makes your house comfortable. The amount of moisture in the air is also an equally 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 warmer, denser and stickier—even if the actual air temperature is cool.
Too much indoor moisture can also contribute to 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 extracting enough moisture.
8 Common Reasons Your Home Feels Humid
Making your home in Columbia, Mississippi, muggy conditions can be a problem.
Countless area homeowners wonder the same question: Why does my home feel so humid?
There are a variety of common explanations. Understanding what's creating excess humidity is a key first step toward fixing the problem.
Below are several common reasons for high indoor humidity levels in Columbia, Mississippi:
1. Oversized Air Conditioning
An AC that's bigger than your home needs cools your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it stops operating before completing a full cooling cycle.
2. Dirty Air Filter
A blocked air filter restricts airflow throughout your heting and cooling system. This makes it harder for your equipment to remove moisture while cooling your home.
3. Blocked Condensate Drain
Your air conditioner removes moisture from your indoor air and drains it outside through a condensate line. If that drain becomes clogged, moisture can't drain from the system properly, contributing to increased humidity levels.
4. Frozen Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's indoor air. Dirt and grime on the coil limits its effectiveness and often requires professional AC repair services to restore performance.
5. Loose Ductwork
Ductwork carries cool air throughout your home. Openings in ductwork can allow warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This added moisture makes it harder to maintain comfortable humidity levels.
6. Thermostat Fan Running on “On” Change to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower continues to operate after the cooling cycle is finished. This can circulate moisture collected on the evaporator coil back into your home instead of allowing it to drain away.
7. Unusually Humid Weather
During the area’s very humid summer weather, your HVAC system has to work harder to remove moisture from the air. Even when your air conditioner is operating correctly, 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 improves performance, boosts efficiency and helps find worn-out parts. Skipping regular air conditioning maintenance can decrease performance, including your system's ability to reduce moisture.
Simple Checks to Make Before Scheduling an HVAC Technician
If your home feels humid, there are some simple things you can check before requesting service. These DIY tips are easy ways to improve indoor comfort by helping your AC or heating system remove moisture more effectively.
- 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 leave the system after each cooling cycle instead of being sent back into your living spaces.
- Make sure supply and return vents are open and unblocked. Rugs or furniture over the vents or closed vents can restrict airflow throughout your home.
- Look for water around the indoor unit. Water by your AC equipment may suggest a clogged condensate drain or another drainage-related issue.
- Know how your AC 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 checked by a professional.
Even if your thermostat still says cool but house feels humid, do not attempt repairs with refrigerant, electrical components or internal parts. Do-it-yourself fixes may be tempting, but these repairs require professional training and should always be left to a qualified HVAC technician.
Could You Benefit from 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 worth considering. As opposed to portable units that only work in one room or area, a whole-home dehumidifier works alongside your HVAC system to manage humidity throughout your entire house.
