The warm summers in Harrisonville and Raymore, Missouri, can get muggy and uncomfortable. You set the thermostat to a comfortable temperature. The AC kicks on automatically. But, even after your air conditioner operates, 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 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. Your temperature only tells you how hot or cold the air is within the space. It doesn't measure how much moisture is in the air. When humidity levels are too high, your home can feel warmer 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 right and basic troubleshooting steps you can try to reduce humidity in your Harrisonville and Raymore, Missouri, home. That way, you’ll know when it’s time to call experts like the team at Balance Point Heating & Cooling for support.
Why Your Home Can Feel Humid Even When the Temperature Is Cool
Your home's temperature is only part of what makes your house enjoyable. Humidity is also an equally important factor. Many homes are typically more comfortable when indoor relative humidity stays 30-50 percent. When a home has high indoor humidity, the air feels hotter, more oppressive and stickier—even if the actual air temperature is cool.
Excess 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 cooling the air without pulling out enough moisture.
Home Feels Humid? Here are 8 Common Causes
Living in Harrisonville and Raymore, Missouri, excess moisture can be a challenge.
Plenty of area homeowners wonder the same question: What's making my house feel humid?
There are several common causes. Understanding what's creating excess humidity is a good first step toward solving the problem.
Below are several common reasons for high indoor humidity levels in Harrisonville and Raymore, Missouri:
AC is Too Large
1. AC is Too Large
An AC that's larger than your home actually needs cools down your home too quickly. The problem is an oversized AC often doesn’t eliminate humidity effectively because it turns off before completing a full cooling cycle.
2. Blocked Air Filter
A blocked air filter restricts airflow throughout your HVAC system. This makes it harder for your equipment to extract humidity while cooling your home.
3. Clogged Condensate Drain
Your air conditioning collects moisture from your home’s air and drains it outside through a condensate line. If that drain becomes restricted, moisture can't exit the system properly, contributing to excess moisture indoors.
4. Icy Evaporator Coil
The evaporator coil extracts both heat and moisture from your home's indoor air. Dirt buildup on the coil decreases its effectiveness and often requires professional AC repair services to fix.
5. Damaged Ductwork
Ductwork moves cool air throughout your home. Openings in ductwork can pull warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This additional moisture makes it more challenging to maintain comfortable humidity levels.
6. Thermostat Fan Set to “On” Switch to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower keeps running after the cooling cycle completes. This can blow moisture collected on the evaporator coil back into your home instead of allowing it to drain away.
7. Extremely Humid Weather
During the area’s especially humid summer weather, your HVAC system has to run longer to remove moisture from the air. Even when your air conditioner is working properly, sometimes your home feels muggy because outdoor humidity continues to seep into your home through doors, windows and normal air leakage.
8. Aging Heating and Cooling Equipment
As HVAC systems age, they often become less efficient at controlling humidity. HVAC maintenance improves performance, boosts efficiency and helps identify worn-out parts. Neglecting regular air conditioning maintenance can decrease performance, including your system's ability to reduce moisture.
What You Can Check Before Scheduling an HVAC Technician
If your house feels humid, there are some simple things you can check before booking service. These strategies are easy ways to improve indoor comfort by helping your heating and cooling system remove moisture more efficiently.
- Replace or inspect the air filter. A clean HVAC air filter allows proper airflow, helping your system circulate air through 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 sent back into your living spaces.
- Make sure 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 near your AC equipment may indicate 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 continuously, 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 internal parts. DIY repairs may be tempting, but these repairs require advanced 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 help reduce moisture in one room or area, a whole-home dehumidifier works alongside your HVAC system to control humidity throughout your entire house.
