The warm summers in Norco and surrounding parishes, Louisiana, can get muggy and uncomfortable. You set the thermostat to a pleasant temperature. The air conditioner starts up automatically. But, even after your AC runs, your home still feels damp and sticky.
Now, you’re cool and damp.
It can be disappointing when the air conditioner seems to operate normally, 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 things. The temperature only tells you how comfortable the air is within the room. It doesn't measure how much humidity is in your home. When indoor moisture is 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 indoor comfort levels, common reasons your home feels humid even when the temperature is comfortable and basic troubleshooting steps you can try to reduce humidity in your Norco and surrounding parishes, Louisiana, home. That way, you’ll know when it’s time to contact experts like the team at Mayeuxs AC & Heating for professional help.
Why Your Home Can Feel Humid Even When the Temperature Is Right
Your home's temperature is only part of what makes your home enjoyable. Humidity is another important factor. Most homes are typically more comfortable when indoor relative humidity stays between 30% and 50%. When a home has high indoor humidity, the air feels less comfortable, denser 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 lowering the temperature of the air without pulling out enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Living in Norco and surrounding parishes, Louisiana, excess moisture can be a problem.
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 moisture is a key first step toward resolving the problem.
Let's look at several common reasons for high indoor humidity levels in Norco and surrounding parishes, Louisiana:
1. AC is Too Large
An AC unit that's too big for your home cools 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. Dirty Air Filter
A dirty air filter limits 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. Frozen 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. Leaky Ductwork
Ductwork carries cool air throughout your house. Leaks in ductwork can draw warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This added moisture makes it more difficult to maintain comfortable humidity conditions.
6. Thermostat Fan Running on “On” Switch to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower continues to operate after the cooling cycle is finished. 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 very humid and hot summers, your HVAC system has to work harder to remove moisture from the air. Even when your cooling system is working properly, sometimes your home feels muggy because outdoor humidity continually enters your home through doors, windows and normal air leakage.
8. Poorly Maintained HVAC Equipment
As home comfort systems age, they often become less efficient at controlling humidity. HVAC maintenance enhances performance, improves efficiency and helps detect worn-out parts. Putting off regular air conditioning maintenance can limit performance, including your system's ability to reduce moisture.
Simple Checks to Make Before Scheduling an HVAC Technician
If your house feels humid, there are a few simple things you can check before scheduling service. These simple troubleshooting steps are easy ways to improve indoor comfort by helping your HVAC system remove moisture more effectively.
- Check your HVAC air filter. A clean heating and cooling system air filter allows proper airflow, helping your system condition and dehumidify your home better.
- 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.
- Check to ensure your supply and return vents are open and unblocked. Rugs or household furnishings 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 suggest a clogged condensate drain or another drain problem.
- Pay attention to how your air conditioning should run. If the AC is short cycling or turning on and off frequently, or it seems to run constantly without improving comfort, 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 involving refrigerant, electrical components or internal HVAC parts. Do-it-yourself fixes may be tempting, but these repairs require professional training and should always be left to a qualified HVAC technician.
Does Your Home Need a Whole-Home Dehumidifier?
If you have humidity in your house during summer or year-round moisture problems, a whole-home dehumidifier may be worth considering.
