The hot and humid summers in Cottonwood & Verde Valley, Arizona, can get muggy and uncomfortable. You change the thermostat to a comfortable temperature. The air conditioning kicks on automatically. But, even after your air conditioner operates, your home still feels moist and clammy.
Now, you’re cool and damp.
It can be annoying when the air conditioner appears to work properly, yet your home doesn't actually feel comfortable. If your rooms feel humid but thermostat says cool, you're not the only homeowner. Many area homeowners have this problem.
The reason is simple: Temperature and humidity are two different measurements in your home. The temperature only tells you how hot or cold the air is within your home. It doesn't measure how much humidity is in your home. When indoor moisture is extremely high, your home can feel several degrees warmer than the thermostat indicates, due to indoor humidity problems.
In this guide, you'll learn how humidity affects your comfort, common reasons your home feels humid even when the temperature is correct and simple troubleshooting steps you can try to reduce humidity in your Cottonwood & Verde Valley, Arizona, home. That way, you’ll know when you should contact experts like the team at Connolly Electric & Mechanical for support.
Why Your Home Can Feel Humid Even When the Temperature Is Cool
Your home's temperature is only part of what makes your living space comfortable. Humidity is also an equally important factor. Most homes are typically more comfortable when indoor relative humidity falls between 30% and 50%. When a home has high indoor humidity, the air feels hotter, heavier and stickier—even if the actual air temperature is cool.
Too much indoor moisture can also promote 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 lowering the temperature of the air without pulling out enough moisture.
Home Feels Humid? Here are 8 Common Causes
Living in Cottonwood & Verde Valley, Arizona, muggy conditions can be a frequent concern.
Many area homeowners wonder the same question: What's making my house feel humid?
There are a variety of common explanations. Determining what's creating excess humidity is the best place to start toward solving the problem.
Let's look at several common reasons for indoor humidity problems in Cottonwood & Verde Valley, Arizona:
Oversized Air Conditioner
1. Oversized Air Conditioning
An AC that's bigger than your home needs cools your home too quickly. The problem is an oversized AC often doesn’t remove humidity effectively because it shuts off before completing a complete cooling cycle.
2. Clogged Air Filter
A clogged air filter restricts airflow throughout your heting and cooling system. This makes it challenging for your equipment to control humidity while cooling your home.
3. Blocked Condensate Drain
Your air conditioning collects moisture from the air in your home and that excess water drains from the unit through a condensate line. If that drain becomes restricted, moisture can't drain from the system properly, contributing to excess moisture indoors.
4. Frozen Evaporator Coil
The evaporator coil removes both heat and moisture from your home's indoor air. Dirt buildup on the coil limits its effectiveness and often requires professional AC repair services to fix.
5. Loose Ductwork
Ductwork moves cool air throughout your home. Openings 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 conditions.
6. Thermostat Fan Set to “On” Change to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower continues to operate after the cooling cycle is finished. 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 very humid summers, your HVAC system has to run longer to remove moisture from the air. Even when your air conditioner is working properly, sometimes your home feels muggy because outdoor humidity keeps entering your home through doors, windows and normal air leakage.
8. Poorly Maintained Heating and Cooling Equipment
As heating and cooling systems age, they often become less effective at controlling humidity. HVAC maintenance optimizes performance, improves efficiency and helps identify worn-out parts. Skipping regular air conditioning maintenance can decrease performance, including your system's ability to control moisture.
Simple Checks to Make Before Calling an HVAC Technician
If your home feels humid, there are a few simple things you can check before booking service. These strategies are easy ways to improve indoor comfort by helping your heating and cooling system remove moisture more effectively.
- Check your HVAC air filter. A clean heating and cooling system air filter allows proper airflow, helping your system circulate air through and dehumidify your home effectively.
- Confirm the thermostat fan is set to Auto. This allows moisture to leave the system after each cooling cycle instead of being sent back into your living spaces.
- Check to ensure your supply and return vents are open and not covered up. 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 indicate a clogged condensate drain or another drainage-related issue.
- Monitor how your air conditioner 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 checked 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 advanced training and should always be performed by a qualified HVAC technician.
Should You Get a Whole-Home Dehumidifier?
