The hot and humid summers in Cache Valley, Utah, can get muggy and uncomfortable. You set the thermostat to a pleasant temperature. The AC kicks on as expected. But, even after your cooling system runs, your home still feels moist and clammy.
Now, you’re cool and damp.
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 factors in indoor comfort. Your temperature only tells you how warm or cool the air is within the room. It doesn't measure how much humidity is in your home. When moisture levels are extremely high, your home can feel several degrees 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 correct and basic troubleshooting steps you can try to reduce humidity in your Cache Valley, Utah, home. That way, you’ll know when it’s time to reach out to experts like the team at Western Mechanical, Inc. for professional help.
Why a Home Can Feel Humid Even If the Temperature Is Nice and Cool
The temperature is only part of what makes your house comfortable. Indoor humidity is also an equally important factor. Many homes are generally more comfortable when indoor relative humidity stays in the 30-50% range. When a home has high indoor humidity, the air feels warmer, more oppressive and stickier—even if the actual air temperature is cool.
Too much indoor moisture can also encourage 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.
8 Common Reasons Your Home Feels Humid
Making your home in Cache Valley, Utah, excess moisture can be a frequent concern.
Countless area homeowners deal with the same question: Why does my home feel so humid?
There could be multiple reasons. Understanding what's creating humidity problems is a key first step toward solving the problem.
Let's look at several common reasons for indoor humidity problems in Cache Valley, Utah:
Oversized Air Conditioner
1. Oversized Air Conditioner
An AC that's too big for your home cools your home too quickly. The problem is an oversized AC often doesn’t eliminate humidity effectively because it stops operating before completing a complete cooling cycle.
2. Dirty Air Filter
A clogged air filter restricts 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 blocked, moisture can't leave 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. 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. Gaps in ductwork can allow warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This added moisture makes it more challenging to maintain comfortable humidity levels.
6. Thermostat Fan Set to “On” Switch to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower continues to operate after the cooling cycle completes. This can push moisture collected on the evaporator coil back into your home instead of giving it time for it to drain away.
7. Extremely 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 air conditioning is functioning as designed, sometimes your home feels muggy because outdoor humidity continues to seep into your home through doors, windows and normal air leakage.
8. Aging HVAC Equipment
As heating and cooling systems age, they often become less effective at controlling humidity. HVAC maintenance enhances performance, increases efficiency and helps find worn-out parts. Skipping 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 a few simple things you can check before booking service. These simple troubleshooting steps are easy ways to improve indoor comfort by helping your AC or heating system remove moisture more efficiently.
- Replace or inspect the air filter. A clean HVAC air filter allows proper airflow, helping your system condition and dehumidify your home better.
- Make sure the thermostat fan is set to Auto. This allows moisture to leave the system after each cooling cycle instead of being circulated back into your living spaces.
- Check that supply and return vents are open and unblocked. Rugs or household furnishings over the vents or closed vents can restrict airflow throughout your home.
- Check for water around the indoor unit. Water around your AC equipment may indicate a clogged condensate drain or another drain problem.
- Pay attention to how your AC should run. If the AC is short cycling or turning on and off repeatedly, 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 involving refrigerant, electrical components or internal HVAC parts. Handling these repairs yourself may be tempting, but these repairs require specialized 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 the right choice. Compared with portable units that only help reduce moisture in one room or area, a whole-home dehumidifier works with your HVAC system to reduce humidity throughout your entire house.
