The hot and humid summers in Mobile, Alabama, can get muggy and uncomfortable. You adjust the thermostat to a ideal temperature. The air conditioner starts up as expected. But, even after your air conditioner operates, your home still feels damp and sticky.
Now, you’re cool and damp.
It can be frustrating when the air conditioner seems to operate normally, yet your home doesn't actually feel comfortable. If your rooms feel humid but thermostat says cool, you're in good company. It happens a lot.
Why is this? Temperature and humidity are two different measurements in your home. Your temperature only tells you how hot or cold the air is within the space. It doesn't measure the amount of moisture 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 guide, you'll learn how humidity affects your comfort, common reasons your home feels humid even when the temperature is right and simple troubleshooting steps you can try to reduce humidity in your Mobile, Alabama, home. That way, you’ll know when to contact experts like the team at Farnell Heating & Air Conditioning Inc for expert assistance.
Why Your Home Can Feel Humid Even When the Temperature Is Cool
Indoor temperature is only part of what makes your home pleasant. The amount of moisture in the air is another important consideration. The majority of homes are generally more comfortable when indoor relative humidity falls 30-50 percent. When a home has high indoor humidity, the air feels less comfortable, more oppressive and stickier—even if the actual air temperature is cool.
Excess 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 lowering the temperature of the air without removing enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Living in Mobile, Alabama, high humidity can be a frequent concern.
Plenty of area homeowners deal with the same question: Why does my house feel humid?
There could be multiple reasons. Understanding what's creating humidity problems is a good first step toward resolving the problem.
Below are several common reasons for indoor humidity problems in Mobile, Alabama:
1. AC is Too Large
An AC that's bigger than your home needs cools your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it shuts off before completing a complete cooling cycle.
2. Dirty Air Filter
A clogged air filter reduces airflow throughout your HVAC system. This makes it more difficult for your equipment to control humidity while cooling your home.
3. Blocked Condensate Drain
Your air conditioner collects moisture from your indoor air and that excess water drains from the unit through a condensate line. If that drain becomes restricted, moisture can't leave the system properly, contributing to excess moisture indoors.
4. Icy Evaporator Coil
The evaporator coil removes 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 moves cool air throughout your house. Gaps in ductwork can pull warm, humid air from attics, crawl spaces or other unused 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 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 and hot summers, your HVAC system has to run longer to remove moisture from the air. Even when your air conditioner is operating correctly, 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 find worn-out parts. Neglecting regular air conditioning maintenance can limit performance, including your system's ability to remove moisture.
Simple Checks to Make Before Scheduling an HVAC Technician
If your house feels humid, there are several simple things you can check before scheduling service. These DIY tips are easy ways to improve indoor comfort by helping your heating and cooling system remove moisture more effectively.
- Replace a dirty air filter. A clean heating and cooling system air filter allows proper airflow, helping your system circulate air through and dehumidify your home more efficiently.
- Confirm 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. Furniture over the vents or closed vents can reduce 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 AC should run. If the AC is short cycling or turning on and off repeatedly, or it seems to run constantly without cooling your home like it should, 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. Handling these repairs yourself may be tempting, but these repairs require advanced training and should always be handled by a qualified HVAC technician.
Could You Benefit from a Whole-Home Dehumidifier?
