The humid summers in Delray Beach, Florida, can get muggy and uncomfortable. You set the thermostat to a ideal temperature. The air conditioning kicks on right away. But, even after your AC operates, your home still feels damp and sticky.
That’s not very comfortable.
It can be annoying when the air conditioner appears to work properly, yet your home doesn't actually feel very comfortable. If your rooms feel humid but thermostat says cool, you're in good company. Many area homeowners have this problem.
Why? Temperature and humidity are two different measurements in your home. The temperature only tells you how comfortable the air is within your home. It doesn't measure how much moisture is in the air. When humidity levels are too high, your home can feel warmer than the thermostat indicates, due to indoor humidity problems.
In this article, you'll learn how humidity affects your home comfort, common reasons your home feels humid even when the temperature is right and basic troubleshooting steps you can try to reduce humidity in your Delray Beach, Florida, home. That way, you’ll know when you should reach out to experts like the team at Kilbourne Heating & AC for expert assistance.
Why a Home Can Feel Humid Even Though the Temperature Is Nice and Cool
The temperature is only part of what makes your living space enjoyable. The amount of moisture in the air is an extremely important factor. Many homes are typically more comfortable when indoor relative humidity stays 30-50 percent. When a home has high indoor humidity, the air feels hotter, denser 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 chilling the air without pulling out enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Living in Delray Beach, Florida, high humidity can be a frequent concern.
Plenty of area homeowners ask the same question: What's making my house feel humid?
There could be multiple reasons. Understanding what's creating excess humidity is a good first step toward fixing the problem.
Here are several common reasons for high indoor humidity levels in Delray Beach, Florida:
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 turns off before completing a proper cooling cycle.
2. Blocked Air Filter
A blocked air filter reduces airflow throughout your HVAC system. This makes it challenging for your equipment to remove moisture while cooling your home.
3. Clogged Condensate Drain
Your air conditioner removes moisture from the air in your home and drains it outside through a condensate line. If that drain becomes restricted, moisture can't drain from the system properly, contributing to increased humidity levels.
4. Dirty Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air supply. Dirt and grime on the coil reduces its effectiveness and often requires professional AC repair services to fix.
5. Leaky Ductwork
Ductwork transports cool air throughout your living space. Leaks in ductwork can draw warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This additional moisture makes it harder to maintain comfortable humidity conditions.
6. Thermostat Fan Set to “On” Switch to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower continues to operate after the cooling cycle completes. This can circulate moisture collected on the evaporator coil back into your home instead of giving it time for it to drain away.
7. Exceptionally Humid Weather
During the area’s especially humid summer weather, your HVAC system has to run longer to remove moisture from the air. Even when your AC is operating correctly, 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 efficient at controlling humidity. HVAC maintenance improves performance, increases efficiency and helps detect worn-out parts. Skipping regular air conditioning maintenance can limit performance, including your system's ability to control moisture.
What You Can Check Before Contacting an HVAC Technician
If your home 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 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 cool and dehumidify your home better.
- Confirm the thermostat fan is set to Auto. This allows moisture to flow out after each cooling cycle instead of being circulated back into your living spaces.
- Check that supply and return vents are open and not covered up. Furniture over the vents or closed vents can limit airflow throughout your home.
- Inspect for water around the indoor unit. Water near your AC equipment may signal a clogged condensate drain or another drain problem.
- 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 like it should, it's time to have the system inspected by a professional.
Even if your thermostat still says cool but house feels humid, do not attempt repairs with refrigerant, electrical components or system components. Handling these repairs yourself may be tempting, but these repairs require advanced training and should always be handled by a qualified HVAC technician.
Should You Get a Whole-Home Dehumidifier?
If you have humidity in your house during summer or year-round moisture problems, a whole-home dehumidifier may be the right choice.
