The hot and humid summers in Mankato area, Minnesota, can get muggy and uncomfortable. You set the thermostat to a ideal temperature. The AC kicks on right away. But, even after your air conditioner operates, your home still feels damp and sticky.
Not a great feeling.
It can be disappointing when the air conditioner seems to operate normally, 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 is this? Temperature and humidity are two different factors in indoor comfort. Your temperature only tells you how hot or cold the air is within the room. It doesn't measure the amount of moisture in the air. When humidity levels are very high, your home can feel much hotter than the thermostat indicates, due to indoor humidity problems.
In this guide, you'll learn how humidity affects your home comfort, common reasons your home feels humid even when the temperature is comfortable and simple troubleshooting steps you can try to reduce humidity in your Mankato area, Minnesota, home. That way, you’ll know when to call experts like the team at Northern Comfort Inc for support.
Why a Home Can Feel Humid Even When the Temperature Is Cool
Your home's temperature is only part of what makes your house enjoyable. Indoor humidity is another important factor. Most homes are typically more comfortable when indoor relative humidity falls between 30% and 50%. 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 removing enough moisture.
Home Feels Humid? Here are 8 Common Causes
Residing in Mankato area, Minnesota, excess moisture can be a challenge.
Many area homeowners ask the same question: Why does my house feel humid?
There are a variety of common explanations. Understanding what's creating humidity problems is a key first step toward fixing the problem.
Let's look at several common reasons for elevated indoor humidity in Mankato area, Minnesota:
AC is Too Large
1. Oversized Air Conditioner
An air conditioner that's too big for your home 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 complete cooling cycle.
2. Clogged Air Filter
A dirty air filter reduces airflow throughout your HVAC system. This makes it challenging for your equipment to remove moisture while cooling your home.
3. Obstructed Condensate Drain
Your AC removes moisture from your indoor air and and then it drains from the equipment through a condensate line. If that drain becomes restricted, moisture can't drain from the system properly, contributing to increased humidity levels.
4. Icy Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air supply. Ice formation or excessive dirt on the coil decreases its effectiveness and often requires professional AC repair services to restore performance.
5. Loose Ductwork
Ductwork carries cool air throughout your house. Gaps in ductwork can draw warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This added moisture makes it more difficult to maintain comfortable humidity throughout your home.
6. Thermostat Fan is on “On” Setting Change 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 circulate moisture collected on the evaporator coil back into your home instead of allowing it to drain away.
7. Extremely Humid Weather
During the area’s extremely 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 continually enters 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 optimizes performance, increases efficiency and helps identify worn-out parts. Putting off regular air conditioning maintenance can decrease performance, including your system's ability to control moisture.
Simple Checks to Make Before Scheduling an HVAC Technician
If your house feels humid, there are some simple things you can check before requesting service. These simple troubleshooting steps are easy ways to improve indoor comfort by helping your HVAC system remove moisture more effectively.
- Replace a dirty air filter. A clean HVAC 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 leave the system after each cooling cycle instead of being sent back into your living spaces.
- Make sure supply and return vents are open and unblocked. Rugs or furniture over the vents or closed vents can restrict airflow throughout your home.
- Look for water around the indoor unit. Water around your AC equipment may suggest a clogged condensate drain or another drain problem.
- Monitor 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 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 with refrigerant, electrical components or internal HVAC parts. Do-it-yourself fixes may be tempting, but these repairs require advanced training and should always be performed by a qualified HVAC technician.
Could You Benefit from a Whole-Home Dehumidifier?
