The hot and humid summers in Redding, California, can get muggy and uncomfortable. You set the thermostat to a comfortable temperature. The AC starts up automatically. But, even after your air conditioner runs, your home still feels moist and clammy.
That’s not very comfortable.
It can be frustrating when the air conditioner seems to be doing its job, yet your home doesn't actually feel 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. A temperature only tells you how warm or cool the air is within your home. It doesn't measure how much humidity is in your home. When humidity levels are extremely high, your home can feel warmer than the thermostat indicates, due to indoor humidity problems.
In this guide, you'll learn how humidity affects your indoor comfort levels, common reasons your home feels humid even when the temperature is right and easy troubleshooting steps you can try to reduce humidity in your Redding, California, home. That way, you’ll know when to reach out to experts like the team at Allianz Heating & Air for professional help.
Why a Home Can Feel Humid Even If the Temperature Is Right
Indoor temperature is only part of what makes your home comfortable. Indoor humidity is another important element to consider. Most homes are the most comfortable when indoor relative humidity stays 30-50 percent. 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 promote 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
Residing in Redding, California, high humidity can be a challenge.
Many area homeowners deal with the same question: Why does my home feel so humid?
There are several common causes. Determining what's creating humidity problems is a good first step toward fixing the problem.
Let's look at several common reasons for high indoor humidity levels in Redding, California:
1. Oversized Air Conditioner
An AC 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 stops operating before completing a proper cooling cycle.
2. Blocked Air Filter
A dirty air filter reduces airflow throughout your HVAC system. This makes it more difficult for your equipment to control humidity while cooling your home.
3. Clogged Condensate Drain
Your AC collects moisture from the air in your home and drains it outside through a condensate line. If that drain becomes clogged, moisture can't leave the system properly, contributing to higher indoor humidity.
4. Dirty Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's indoor air. Dirt buildup on the coil reduces its effectiveness and often requires professional AC repair services to restore performance.
5. Loose Ductwork
Ductwork transports cool air throughout your home. Gaps in ductwork can pull warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This extra moisture makes it more challenging to maintain comfortable humidity throughout your home.
6. Thermostat Fan Set to “On” Change to “Auto”
If your thermostat fan is running on "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. Unusually Humid Weather
During the area’s extremely humid summers, 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. Poorly Maintained HVAC Equipment
As HVAC systems wear out over time, they often become less capable at controlling humidity. HVAC maintenance enhances performance, boosts efficiency and helps find worn-out parts. Putting off regular air conditioning maintenance can limit performance, including your system's ability to control moisture.
What You Can Check Before Scheduling an HVAC Technician
If your house feels humid, there are a few simple things you can check before booking service. These DIY tips 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 heating and cooling system 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 leave the system after each cooling cycle instead of being blown back into your living spaces.
- Make sure supply and return vents are open and unobstructed. Furniture 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 signal 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 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 attempt 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.
Should You Get a Whole-Home Dehumidifier?
If you deal with humidity in your house during summer or year-round moisture problems, a whole-home dehumidifier may be the right choice. Unlike portable units that only work in one room or area, a whole-home dehumidifier connects to your HVAC system to control humidity throughout your entire house.
