The humid summers in Northglenn, Colorado, can get muggy and uncomfortable. You adjust the thermostat to a ideal temperature. The AC starts up automatically. But, even after your air conditioner operates, your home still feels moist and clammy.
That’s not very comfortable.
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 alone. It happens a lot.
Why is this? Temperature and humidity are two different factors in indoor comfort. A temperature only tells you how warm or cool the air is within the room. It doesn't measure how much moisture is 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 article, you'll learn how humidity affects your indoor comfort levels, common reasons your home feels humid even when the temperature is comfortable and basic troubleshooting steps you can try to reduce humidity in your Northglenn, Colorado, home. That way, you’ll know when to call experts like the team at Northglenn Heating & Air Conditioning for professional help.
Why Your Home Can Feel Humid Even If the Temperature Is Cool
Indoor temperature is only part of what makes your living space enjoyable. The amount of moisture in the air is another important consideration. Most homes are the most comfortable when indoor relative humidity is between 30% and 50%. When a home has high indoor humidity, the air feels less comfortable, heavier 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 cooling the air without removing enough moisture.
Home Feels Humid? Here are 8 Common Causes
Making your home in Northglenn, Colorado, high humidity can be a frequent concern.
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 the best place to start toward solving the problem.
Here are several common reasons for indoor humidity problems in Northglenn, Colorado:
1. Oversized Air Conditioning
An AC that's larger than your home actually needs cools your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it stops operating before completing a complete cooling cycle.
2. Blocked Air Filter
A blocked air filter reduces airflow throughout your HVAC system. This makes it harder for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioning pulls out 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 drain from the system properly, contributing to excess moisture indoors.
4. Frozen Evaporator Coil
The evaporator coil extracts 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. Damaged Ductwork
Ductwork transports cool air throughout your house. Leaks in ductwork can allow warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This additional moisture makes it harder to maintain comfortable humidity throughout your home.
6. Thermostat Fan is on “On” Setting Switch 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 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 continues to seep into your home through doors, windows and normal air leakage.
8. Older HVAC Equipment
As home comfort systems get older, they often become less capable at controlling humidity. HVAC maintenance enhances performance, improves efficiency and helps identify worn-out parts. Skipping regular air conditioning maintenance can reduce performance, including your system's ability to reduce moisture.
Simple Checks to Make Before Scheduling an HVAC Technician
If your house feels humid, there are some simple things you can check before booking service. These strategies are easy ways to improve indoor comfort by helping your AC or heating system remove moisture more effectively.
- Replace or inspect the air filter. A clean HVAC air filter allows proper airflow, helping your system circulate air through and dehumidify your home better.
- Verify the thermostat fan is set to Auto. This allows moisture to flow out after each cooling cycle instead of being blown back into your living spaces.
- Check to ensure your supply and return vents are open and unblocked. Rugs or furniture 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 indicate a clogged condensate drain or another drainage-related issue.
- Monitor how your AC 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 evaluated by a professional.
Even if your thermostat still says cool but house feels humid, do not perform repairs involving 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.
