The hot and humid summers in Dundas and Northfield, Minnesota, can get muggy and uncomfortable. You change the thermostat to a comfortable temperature. The air conditioner begins running right away. But, even after your air conditioner cycles, your home still feels moist and clammy.
That’s not very comfortable.
It can be annoying 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 factors in indoor comfort. 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 humidity levels are very 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 basic troubleshooting steps you can try to reduce humidity in your Dundas and Northfield, Minnesota, home. That way, you’ll know when to contact experts like the team at Better Air for professional help.
Why Your Home Can Feel Humid Even If the Temperature Is Cool
Your home's temperature is only part of what makes your home enjoyable. Humidity is another important element to consider. The majority of homes are generally more comfortable when indoor relative humidity is 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.
High humidity can also encourage 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 pulling out enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Making your home in Dundas and Northfield, Minnesota, excess moisture can be a problem.
Many area homeowners wonder the same question: Why does my home feel so humid?
There are a variety of common explanations. Identifying what's creating humidity problems is a key first step toward fixing the problem.
Here are several common reasons for indoor humidity problems in Dundas and Northfield, Minnesota:
AC is Too Large
1. AC is Too Large
An AC 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 eliminate humidity effectively because it turns off before completing a proper cooling cycle.
2. Clogged Air Filter
A dirty air filter reduces airflow throughout your heting and cooling system. This makes it harder for your equipment to remove moisture while cooling your home.
3. Clogged Condensate Drain
Your air conditioning pulls out 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 drain from the system properly, contributing to excess moisture indoors.
4. Dirty Evaporator Coil
The evaporator coil extracts both heat and moisture from your home's indoor air. Ice formation or excessive dirt on the coil decreases its effectiveness and often requires professional AC repair services to restore performance.
5. Damaged Ductwork
Ductwork moves cool air throughout your house. Gaps in ductwork can allow warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This additional moisture makes it more difficult to maintain comfortable humidity conditions.
6. Thermostat Fan Set to “On” Change to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower continues running after the cooling cycle ends. This can circulate moisture collected on the evaporator coil back into your home instead of allowing it to drain away.
7. Exceptionally Humid Weather
During the area’s very humid summers, your HVAC system has to operate more to remove moisture from the air. Even when your AC is functioning as designed, 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 enhances performance, boosts efficiency and helps find worn-out parts. Skipping regular air conditioning maintenance can decrease performance, including your system's ability to remove moisture.
What You Can Check Before Calling an HVAC Technician
If your home feels humid, there are several simple things you can check before booking service. These strategies are easy ways to improve indoor comfort by helping your HVAC system remove moisture more effectively.
- Replace or inspect the air filter. A clean HVAC air filter allows proper airflow, helping your system condition and dehumidify your home more efficiently.
- Make sure 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.
- Check to ensure your supply and return vents are open and unobstructed. Rugs or furniture over the vents or closed vents can limit airflow throughout your home.
- Inspect for water around the indoor unit. Water by your AC equipment may indicate a clogged condensate drain or another drainage-related issue.
- Pay attention to 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, 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 with refrigerant, electrical components or internal parts. Handling these repairs yourself may be tempting, but these repairs require professional training and should always be left to a qualified HVAC technician.
Could You Benefit from a Whole-Home Dehumidifier?
