The humid summers in Sandpoint, Idaho, can get muggy and uncomfortable. You change the thermostat to a ideal temperature. The air conditioning kicks on right away. But, even after your air conditioner operates, your home still feels damp and sticky.
Now, you’re cool and damp.
It can be disappointing when the air conditioner appears to work properly, yet your home doesn't actually feel pleasant. If your rooms feel humid but thermostat says cool, you're not the only homeowner. It happens a lot.
Why is this? Temperature and humidity are two different things. A temperature only tells you how hot or cold the air is within the space. 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 comfort, common reasons your home feels humid even when the temperature is comfortable and easy troubleshooting steps you can try to reduce humidity in your Sandpoint, Idaho, home. That way, you’ll know when you should reach out to experts like the team at Age Heating & Cooling for support.
Why Your Home Can Feel Humid Even If the Temperature Is Cool
Indoor temperature is only part of what makes your home pleasant. The amount of moisture in the air is an extremely important factor. The majority of homes are generally more 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.
Excess moisture can also contribute to 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 chilling the air without extracting enough moisture.
Home Feels Humid? Here are 8 Common Causes
Making your home in Sandpoint, Idaho, high humidity can be a problem.
Many area homeowners wonder the same question: What's making my house feel humid?
There are several common causes. Determining what's creating excess moisture is a good first step toward solving the problem.
Let's look at several common reasons for indoor humidity problems in Sandpoint, Idaho:
1. Oversized Air Conditioner
An air conditioner that's too big for your home lowers the temperature in your home too quickly. The problem is an oversized AC often doesn’t eliminate humidity effectively because it shuts off before completing a proper cooling cycle.
2. Blocked Air Filter
A clogged air filter restricts airflow throughout your HVAC system. This makes it more difficult for your equipment to extract humidity while cooling your home.
3. Blocked 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 restricted, moisture can't drain from the system properly, contributing to excess moisture indoors.
4. Icy Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air. Dirt buildup on the coil reduces its effectiveness and often requires professional AC repair services to fix.
5. Damaged Ductwork
Ductwork moves cool air throughout your house. Openings in ductwork can allow warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This extra 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 keeps 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 very humid summers, your HVAC system has to operate more 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. Aging HVAC Equipment
As HVAC systems age, they often become less effective at controlling humidity. HVAC maintenance optimizes performance, boosts efficiency and helps identify worn-out parts. Neglecting regular air conditioning maintenance can decrease performance, including your system's ability to remove moisture.
What You Can Check Before Scheduling an HVAC Technician
If your home feels humid, there are several simple things you can check before scheduling service. These simple troubleshooting steps are easy ways to improve indoor comfort by helping your HVAC system remove moisture more efficiently.
- 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 more efficiently.
- Make sure the thermostat fan is set to Auto. This allows moisture to flow out after each cooling cycle instead of being circulated back into your living spaces.
- Check that supply and return vents are open and unobstructed. Rugs or household furnishings over the vents or closed vents can restrict airflow throughout your home.
- Look 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 air conditioning should run. If the AC is short cycling or turning on and off repeatedly, 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 attempt repairs with refrigerant, electrical components or system components. Handling these repairs yourself may be tempting, but these repairs require specialized training and should always be left to a qualified HVAC technician.
Could You Benefit from 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.
