The humid summers in Sarasota, Florida, can get muggy and uncomfortable. You set the thermostat to a ideal temperature. The air conditioner starts up as expected. But, even after your air conditioner runs, your home still feels humid and uncomfortable.
Not a great feeling.
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 not the only homeowner. Local homeowners often have this experience.
Why? Temperature and humidity are two different measurements in your home. A temperature only tells you how hot or cold 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 much hotter than the thermostat indicates, due to indoor humidity problems.
In this blog, you'll learn how humidity affects your comfort, common reasons your home feels humid even when the temperature is comfortable and easy troubleshooting steps you can try to reduce humidity in your Sarasota, Florida, home. That way, you’ll know when to reach out to experts like the team at Airtech Cooling & Heating for professional help.
Why a Home Can Feel Humid Even If the Temperature Is Right
Your home's temperature is only part of what makes your living space comfortable. Humidity is also an equally important consideration. 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 hotter, heavier and stickier—even if the actual air temperature is cool.
Too much indoor moisture can also promote 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 chilling the air without extracting enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Making your home in Sarasota, Florida, high humidity can be a frequent concern.
Countless area homeowners ask the same question: Why does my house feel humid?
There could be multiple reasons. Identifying what's creating excess humidity is the best place to start toward solving the problem.
Here are several common reasons for elevated indoor humidity in Sarasota, Florida:
1. Oversized Air Conditioner
An AC unit 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 stops operating before completing a full cooling cycle.
2. Dirty Air Filter
A dirty air filter limits airflow throughout your heting and cooling system. This makes it challenging for your equipment to remove moisture while cooling your home.
3. Blocked Condensate Drain
Your AC removes moisture from your home’s air and and then it drains from the equipment through a condensate line. If that drain becomes restricted, moisture can't exit the system properly, contributing to higher indoor humidity.
4. Frozen Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air supply. Dirt buildup on the coil reduces its effectiveness and often requires professional AC repair services to restore performance.
5. Leaky Ductwork
Ductwork moves cool air throughout your living space. Openings in ductwork can pull warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This additional moisture makes it more challenging to maintain comfortable humidity conditions.
6. Thermostat Fan is on “On” Setting Change setting to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower keeps running 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 and hot summers, your HVAC system has to operate more to remove moisture from the air. Even when your cooling system 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 Heating and Cooling Equipment
As HVAC systems get older, they often become less effective at controlling humidity. HVAC maintenance optimizes performance, improves efficiency and helps find worn-out parts. Neglecting regular air conditioning maintenance can reduce performance, including your system's ability to reduce moisture.
What You Can Check Before Scheduling an HVAC Technician
If your home feels humid, there are some simple things you can check before requesting service. These strategies are easy ways to improve indoor comfort by helping your HVAC system remove moisture more effectively.
- Replace a dirty air filter. A clean heating and cooling system air filter allows proper airflow, helping your system cool and dehumidify your home effectively.
- Confirm 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 not covered up. Rugs or furniture over the vents or closed vents can restrict airflow throughout your home.
- Check for water around the indoor unit. Water near your AC equipment may signal a clogged condensate drain or another drainage issue.
- Know how your air conditioner should run. If the AC is short cycling or turning on and off repeatedly, or it seems to run constantly without improving comfort, it's time to have the system inspected by a professional.
Even if your thermostat still says cool but house feels humid, do not try repairs involving refrigerant, electrical components or internal HVAC parts. Handling these repairs yourself may be tempting, but these repairs require professional training and should always be handled by a qualified HVAC technician.
Could You Benefit from a Whole-Home Dehumidifier?
If you struggle 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 remove humidity from one room or area, a whole-home dehumidifier connects to your HVAC system to reduce humidity throughout your entire house.
