The warm summers in Buellton, California, can get muggy and uncomfortable. You set the thermostat to a ideal temperature. The AC starts up as expected. But, even after your AC cycles, your home still feels damp and sticky.
Not a great feeling.
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 not alone. Many area homeowners have this problem.
Why? Temperature and humidity are two different measurements in your home. A temperature only tells you how hot or cold the air is within the space. It doesn't measure how much moisture is in the air. 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 indoor comfort levels, common reasons your home feels humid even when the temperature is right and simple troubleshooting steps you can try to reduce humidity in your Buellton, California, home. That way, you’ll know when it’s time to reach out to experts like the team at Allstar Heating & Air Conditioning for support.
Why a Home Can Feel Humid Even Though the Temperature Is Right
The temperature is only part of what makes your house comfortable. The amount of moisture in the air is also an equally important consideration. Most homes are typically more comfortable when indoor relative humidity stays in the 30-50% range. When a home has high indoor humidity, the air feels warmer, denser and stickier—even if the actual air temperature is cool.
Excess 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 extracting enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Living in Buellton, California, high humidity can be a frequent concern.
Plenty of area homeowners ask the same question: Why does my house feel humid?
There are a variety of common explanations. Understanding what's creating excess humidity is a good first step toward fixing the problem.
Here are several common reasons for indoor humidity problems in Buellton, California:
Oversized Air Conditioner
1. AC is Too Large
An AC that's too big for your home lowers the temperature in your home too quickly. The problem is an oversized AC often doesn’t reduce humidity effectively because it shuts off before completing a full cooling cycle.
2. Blocked Air Filter
A blocked air filter restricts airflow throughout your HVAC system. This makes it challenging for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioner removes moisture from the air in your home and drains it outside through a condensate line. If that drain becomes blocked, moisture can't drain from the system properly, contributing to higher indoor humidity.
4. Dirty Evaporator Coil
The evaporator coil removes both heat and moisture from your home's air. Dirt and grime on the coil limits its effectiveness and often requires professional AC repair services to fix.
5. Loose Ductwork
Ductwork carries cool air throughout your living space. Leaks in ductwork can allow warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This added moisture makes it harder to maintain comfortable humidity throughout your home.
6. Thermostat Fan Running on “On” Change to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower keeps running after the cooling cycle ends. This can blow moisture collected on the evaporator coil back into your home instead of letting it to drain away.
7. Unusually Humid Weather
During the area’s very humid summer weather, your HVAC system has to run longer to remove moisture from the air. Even when your AC 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. Older Heating and Cooling Equipment
As heating and cooling systems wear out over time, they often become less effective at controlling humidity. HVAC maintenance improves performance, improves efficiency and helps detect worn-out parts. Skipping 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 booking service. These DIY tips are easy ways to improve indoor comfort by helping your heating and cooling system remove moisture more efficiently.
- Replace or inspect the air filter. A clean HVAC air filter allows proper airflow, helping your system cool and dehumidify your home effectively.
- Verify 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 household furnishings over the vents or closed vents can reduce airflow throughout your home.
- Look for water around the indoor unit. Water by your AC equipment may suggest a clogged condensate drain or another drain problem.
- Know how your air conditioning should run. If the AC is short cycling or turning on and off frequently, or it seems to run constantly without cooling your home like it should, 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 system components. Handling these repairs yourself may be tempting, but these repairs require professional training and should always be performed by a qualified HVAC technician.
Should You Get a Whole-Home Dehumidifier?
If you have humidity in your house during summer or year-round moisture problems, a whole-home dehumidifier may be a good option.
