The hot and humid summers in Harrisonville and Raymore, Missouri, can get muggy and uncomfortable. You set the thermostat to a ideal temperature. The air conditioning kicks on as expected. But, even after your cooling system runs, your home still feels humid and uncomfortable.
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 not alone. Many area homeowners have this problem.
Why? Temperature and humidity are two different things. A temperature only tells you how warm or cool the air is within your home. It doesn't measure how much humidity is in your home. When humidity levels are extremely high, your home can feel several degrees warmer than the thermostat indicates, due to indoor humidity problems.
In this blog, you'll learn how humidity affects your home comfort, common reasons your home feels humid even when the temperature is comfortable and easy troubleshooting steps you can try to reduce humidity in your Harrisonville and Raymore, Missouri, home. That way, you’ll know when you should reach out to experts like the team at Balance Point Heating & Cooling for support.
Why Your Home Can Feel Humid Even If the Temperature Is Nice and Cool
Indoor temperature is only part of what makes your living space comfortable. Humidity is also an equally important consideration. 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 less comfortable, more oppressive and stickier—even if the actual air temperature is cool.
Too much indoor 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 chilling the air without extracting enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Residing in Harrisonville and Raymore, Missouri, high humidity can be a frequent concern.
Many area homeowners wonder the same question: What's making my house feel humid?
There are a variety of common explanations. Determining what's creating high idoor humidity is a key first step toward resolving the problem.
Below are several common reasons for indoor humidity problems in Harrisonville and Raymore, Missouri:
1. Oversized Air Conditioner
An AC unit that's larger than your home actually needs lowers the temperature in your home too quickly. The problem is an oversized AC often doesn’t reduce humidity effectively because it shuts off before completing a full cooling cycle.
2. Blocked Air Filter
A blocked air filter reduces airflow throughout your heting and cooling system. This makes it harder for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioner pulls out moisture from your indoor 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. Frozen Evaporator Coil
The evaporator coil removes both heat and moisture from your home's air. Ice formation or excessive dirt on the coil limits its effectiveness and often requires professional AC repair services to fix.
5. Loose Ductwork
Ductwork carries cool air throughout your house. Openings in ductwork can allow warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This additional moisture makes it more difficult to maintain comfortable humidity levels.
6. Thermostat Fan Set to “On” Change 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 allowing it to drain away.
7. Unusually Humid Weather
During the area’s especially humid 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 continues to seep into your home through doors, windows and normal air leakage.
8. Poorly Maintained Heating and Cooling Equipment
As home comfort systems age, they often become less capable at controlling humidity. HVAC maintenance optimizes performance, boosts efficiency and helps find worn-out parts. Neglecting regular air conditioning maintenance can decrease performance, including your system's ability to control moisture.
Things to Check Before Calling an HVAC Technician
If your house feels humid, there are a few simple things you can check before scheduling service. These strategies are easy ways to improve indoor comfort by helping your AC or heating system remove moisture more efficiently.
- Replace a dirty 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 drain away after each cooling cycle instead of being blown back into your living spaces.
- Make sure supply and return vents are open and unobstructed. Furniture over the vents or closed vents can limit airflow throughout your home.
- Look for water around the indoor unit. Water by your AC equipment may signal a clogged condensate drain or another drainage-related issue.
- Monitor 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, it's time to have the system inspected by a professional.
Even if your thermostat still says cool but house feels humid, do not try repairs involving refrigerant, electrical components or internal parts. DIY repairs may be tempting, but these repairs require specialized training and should always be left to a qualified HVAC technician.
Should You Get 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 the right choice.
