The warm summers in Bloomfield, Indiana, can get muggy and uncomfortable. You change the thermostat to a comfortable temperature. The air conditioner begins running automatically. But, even after your cooling system cycles, your home still feels damp and sticky.
Now, you’re cool and damp.
It can be disappointing when the air conditioner seems to be doing its job, yet your home doesn't actually feel very comfortable. If your rooms feel humid but thermostat says cool, you're in good company. Local homeowners often have this experience.
The reason is simple: Temperature and humidity are two different things. 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 indoor moisture is very high, your home can feel warmer 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 right and easy troubleshooting steps you can try to reduce humidity in your Bloomfield, Indiana, home. That way, you’ll know when to call experts like the team at Stanford Heating & Cooling for professional help.
Why a Home Can Feel Humid Even Though the Temperature Is Cool
Your home's temperature is only part of what makes your living space enjoyable. Humidity is another important consideration. Many homes are typically more comfortable when indoor relative humidity is in the 30-50% range. When a home has high indoor humidity, the air feels hotter, 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 pulling out enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Making your home in Bloomfield, Indiana, high humidity can be a frequent concern.
Countless area homeowners ask the same question: What's making my house feel humid?
There are a variety of common explanations. Determining what's creating excess humidity is a good first step toward fixing the problem.
Below are several common reasons for high indoor humidity levels in Bloomfield, Indiana:
AC is Too Large
1. Oversized Air Conditioner
An AC that's bigger than your home needs cools down your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it shuts off before completing a full cooling cycle.
2. Clogged Air Filter
A dirty air filter limits airflow throughout your HVAC system. This makes it more difficult for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your AC removes moisture from the air in your home and and then it drains from the equipment through a condensate line. If that drain becomes blocked, moisture can't drain from the system properly, contributing to higher indoor humidity.
4. Dirty Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air. Ice formation or excessive dirt on the coil decreases its effectiveness and often requires professional AC repair services to fix.
5. Damaged Ductwork
Ductwork transports cool air throughout your house. Openings in ductwork can draw warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This additional moisture makes it more difficult to maintain comfortable humidity levels.
6. Thermostat Fan Running on “On” Change setting to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower continues running after the cooling cycle is finished. 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 very humid summer weather, your HVAC system has to run longer to remove moisture from the air. Even when your air conditioner is functioning as designed, sometimes your home feels muggy because outdoor humidity continually enters your home through doors, windows and normal air leakage.
8. Older Heating and Cooling Equipment
As HVAC systems age, they often become less capable at controlling humidity. HVAC maintenance optimizes performance, increases efficiency and helps detect worn-out parts. Putting off regular air conditioning maintenance can decrease performance, including your system's ability to control moisture.
What You Can Check Before Calling an HVAC Technician
If your home feels humid, there are some simple things you can check before booking service. These DIY tips are easy ways to improve indoor comfort by helping your heating and cooling system remove moisture more efficiently.
- Replace or inspect the air filter. A clean heating and cooling system air filter allows proper airflow, helping your system condition and dehumidify your home effectively.
- Verify 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 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 by your AC equipment may suggest a clogged condensate drain or another drainage-related issue.
- Know how your air conditioning 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 try repairs involving refrigerant, electrical components or internal parts. DIY repairs may be tempting, but these repairs require advanced training and should always be handled by 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. Compared with portable units that only help reduce moisture in one room or area, a whole-home dehumidifier works with your HVAC system to control humidity throughout your entire house.
