The hot and humid summers in McPherson, Kansas, can get muggy and uncomfortable. You adjust the thermostat to a ideal temperature. The AC kicks on as expected. But, even after your air conditioner operates, 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 pleasant. If your rooms feel humid but thermostat says cool, you're not the only homeowner. Many area homeowners have this problem.
Why is this? Temperature and humidity are two different measurements in your home. The temperature only tells you how hot or cold the air is within the room. It doesn't measure how much moisture is in the air. When humidity levels are very high, your home can feel several degrees warmer 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 simple troubleshooting steps you can try to reduce humidity in your McPherson, Kansas, home. That way, you’ll know when to contact experts like the team at McPherson Quality Air & Plumbing for support.
Why a Home Can Feel Humid Even If the Temperature Is Right
Your home's temperature is only part of what makes your home pleasant. Humidity is another important consideration. Most homes are the most comfortable when indoor relative humidity is 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 promote 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 chilling the air without pulling out enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Living in McPherson, Kansas, excess moisture can be a frequent concern.
Plenty of area homeowners ask the same question: Why does my house feel humid?
There could be multiple reasons. Determining what's creating humidity problems is a good first step toward resolving the problem.
Below are several common reasons for indoor humidity problems in McPherson, Kansas:
Oversized Air Conditioner
1. Oversized Air Conditioner
An air conditioner that's larger than your home actually 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. Clogged Air Filter
A blocked air filter limits airflow throughout your HVAC system. This makes it more difficult for your equipment to remove moisture while cooling your home.
3. Obstructed Condensate Drain
Your air conditioning pulls out moisture from the air in your home and drains it outside through a condensate line. If that drain becomes clogged, moisture can't drain from the system properly, contributing to higher indoor humidity.
4. Icy Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air supply. Ice formation or excessive dirt on the coil limits its effectiveness and often requires professional AC repair services to fix.
5. Loose Ductwork
Ductwork moves cool air throughout your house. Gaps in ductwork can draw warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This extra moisture makes it more difficult to maintain comfortable humidity levels.
6. Thermostat Fan is on “On” Setting Change to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower keeps running after the cooling cycle is finished. This can circulate moisture collected on the evaporator coil back into your home instead of giving it time for it to drain away.
7. Unusually Humid Weather
During the area’s extremely humid summers, your HVAC system has to operate more to remove moisture from the air. Even when your air conditioner is operating correctly, 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 HVAC systems wear out over time, 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 reduce performance, including your system's ability to remove moisture.
Simple Checks to Make Before Calling an HVAC Technician
If your home feels humid, there are a few simple things you can check before scheduling service. These DIY tips are easy ways to improve indoor comfort by helping your HVAC system remove moisture more efficiently.
- Replace a dirty air filter. A clean heating and cooling system air filter allows proper airflow, helping your system cool and dehumidify your home more efficiently.
- Confirm 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. Rugs or furniture over the vents or closed vents can reduce 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.
- Monitor 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, it's time to have the system evaluated 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. 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 worth considering. As opposed to 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.
