The humid summers in Northridge, California, can get muggy and uncomfortable. You set the thermostat to a pleasant temperature. The AC kicks on right away. But, even after your cooling system 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 very comfortable. If your rooms feel humid but thermostat says cool, you're in good company. Many area homeowners have this problem.
Why? Temperature and humidity are two different factors in indoor comfort. The 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 indoor moisture is too 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 correct and easy troubleshooting steps you can try to reduce humidity in your Northridge, California, home. That way, you’ll know when to contact experts like the team at Enertek Air Conditioning & Heating for professional help.
Why Your Home Can Feel Humid Even If the Temperature Is Nice and Cool
Your home's temperature is only part of what makes your living space comfortable. The amount of moisture in the air is an extremely important element to consider. Most homes are typically more comfortable when indoor relative humidity stays 30-50 percent. When a home has high indoor humidity, the air feels hotter, denser and stickier—even if the actual air temperature is cool.
Excess moisture can also encourage dangerous mold growth, mildew, bad smells 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 pulling out enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Living in Northridge, California, muggy conditions can be a challenge.
Many area homeowners ask the same question: Why does my house feel humid?
There are several common causes. Understanding what's creating humidity problems is a good first step toward fixing the problem.
Below are several common reasons for elevated indoor humidity in Northridge, California:
1. AC is Too Large
An AC that's too big for your home cools down your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it turns off before completing a full cooling cycle.
2. Dirty Air Filter
A clogged air filter restricts airflow throughout your HVAC system. This makes it harder for your equipment to extract humidity while cooling your home.
3. Blocked Condensate Drain
Your AC removes moisture from your home’s air and and then it drains from the equipment through a condensate line. If that drain becomes clogged, moisture can't exit the system properly, contributing to higher indoor humidity.
4. Dirty Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air supply. Ice formation or excessive dirt on the coil limits its effectiveness and often requires professional AC repair services to restore performance.
5. Damaged Ductwork
Ductwork moves cool air throughout your living space. Leaks in ductwork can pull warm, humid air from attics, crawl spaces or other unused areas into your HVAC system. This extra moisture makes it harder to maintain comfortable humidity throughout your home.
6. Thermostat Fan Running on “On” Change setting to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower continues to operate after the cooling cycle ends. This can push moisture collected on the evaporator coil back into your home instead of letting it to drain away.
7. Extremely Humid Weather
During the area’s especially humid summer weather, your HVAC system has to operate more to remove moisture from the air. Even when your air conditioning is working properly, sometimes your home feels muggy because outdoor humidity keeps entering your home through doors, windows and normal air leakage.
8. Aging Heating and Cooling Equipment
As home comfort systems get older, they often become less capable at controlling humidity. HVAC maintenance optimizes performance, improves efficiency and helps find worn-out parts. Neglecting regular air conditioning maintenance can reduce 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 a few simple things you can check before requesting service. These DIY tips 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 circulate air through and dehumidify your home more efficiently.
- Confirm 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.
- Make sure supply and return vents are open and not covered up. Rugs or furniture over the vents or closed vents can restrict airflow throughout your home.
- Inspect 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 continuously, or it seems to run constantly without cooling your home like it should, it's time to have the system checked by a professional.
Even if your thermostat still says cool but house feels humid, do not attempt repairs with refrigerant, electrical components or internal HVAC parts. Handling these repairs yourself may be tempting, but these repairs require professional 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.
