The warm summers in Corpus Christi, Texas, can get muggy and uncomfortable. You set the thermostat to a pleasant temperature. The AC starts up automatically. But, even after your air conditioner operates, your home still feels humid and uncomfortable.
Not a great feeling.
It can be annoying when the air conditioner seems to be doing its job, yet your home doesn't actually feel comfortable. If your rooms feel humid but thermostat says cool, you're not the only homeowner. Local homeowners often have this experience.
The reason is simple: Temperature and humidity are two different measurements in your home. The temperature only tells you how comfortable the air is within the space. It doesn't measure how much moisture is in the air. When moisture levels are extremely high, your home can feel much hotter 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 basic troubleshooting steps you can try to reduce humidity in your Corpus Christi, Texas, home. That way, you’ll know when you should call experts like the team at Total Assurance AC & Heating for professional help.
Why Your Home Can Feel Humid Even If the Temperature Is Nice and Cool
The temperature is only part of what makes your living space comfortable. The amount of moisture in the air is another important element to consider. Most 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 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 lowering the temperature of the air without removing enough moisture.
8 Common Reasons Your Home Feels Humid
Making your home in Corpus Christi, Texas, excess moisture can be a challenge.
Plenty of area homeowners ask the same question: What's making my house feel humid?
There are a variety of common explanations. Understanding what's creating high idoor humidity is the best place to start toward resolving the problem.
Below are several common reasons for elevated indoor humidity in Corpus Christi, Texas:
1. AC is Too Large
An AC that's bigger than your home needs cools down your home too quickly. The problem is an oversized AC often doesn’t eliminate humidity effectively because it shuts off before completing a proper cooling cycle.
2. Blocked Air Filter
A dirty air filter reduces airflow throughout your HVAC system. This makes it harder for your equipment to extract humidity while cooling your home.
3. Blocked Condensate Drain
Your air conditioning removes moisture from your home’s air and drains it outside through a condensate line. If that drain becomes clogged, moisture can't drain from the system properly, contributing to excess moisture indoors.
4. Dirty Evaporator Coil
The evaporator coil extracts both heat and moisture from your home's air. Dirt buildup on the coil limits its effectiveness and often requires professional AC repair services to fix.
5. Leaky Ductwork
Ductwork transports cool air throughout your house. Gaps in ductwork can allow warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This added moisture makes it harder to maintain comfortable humidity throughout your home.
6. Thermostat Fan Set to “On” Change setting to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower keeps running after the cooling cycle ends. This can push moisture collected on the evaporator coil back into your home instead of letting it to drain away.
7. Unusually Humid Weather
During the area’s very humid and hot summers, your HVAC system has to operate more to remove moisture from the air. Even when your air conditioning is functioning as designed, sometimes your home feels muggy because outdoor humidity keeps entering your home through doors, windows and normal air leakage.
8. Poorly Maintained HVAC Equipment
As HVAC systems wear out over time, they often become less effective at controlling humidity. HVAC maintenance optimizes performance, improves efficiency and helps detect worn-out parts. Putting off regular air conditioning maintenance can decrease performance, including your system's ability to control moisture.
Things to Check Before Contacting an HVAC Technician
If your home feels humid, there are several simple things you can check before booking service. These DIY tips are easy ways to improve indoor comfort by helping your HVAC system remove moisture more efficiently.
- Check your HVAC air filter. A clean heating and cooling system air filter allows proper airflow, helping your system cool 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 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 near your AC equipment may indicate a clogged condensate drain or another drainage issue.
- Know 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 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 perform repairs with refrigerant, electrical components or internal parts. Handling these repairs yourself 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.
