The hot and humid summers in Sandpoint, Idaho, can get muggy and uncomfortable. You adjust the thermostat to a ideal temperature. The AC begins running right away. But, even after your AC runs, your home still feels moist and clammy.
Not a great feeling.
It can be annoying when the air conditioner seems to be doing its job, yet your home doesn't actually feel very comfortable. If your rooms feel humid but thermostat says cool, you're not the only homeowner. Local homeowners often have this experience.
Why is this? Temperature and humidity are two different measurements in your home. A temperature only tells you how hot or cold the air is within your home. It doesn't measure the amount of moisture in the air. When moisture levels are too high, your home can feel warmer 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 basic troubleshooting steps you can try to reduce humidity in your Sandpoint, Idaho, home. That way, you’ll know when to call experts like the team at Age Heating & Cooling for support.
Why Your Home Can Feel Humid Even If the Temperature Is Cool
Your home's temperature is only part of what makes your home enjoyable. The amount of moisture in the air is also an equally important element to consider. Most homes are typically more comfortable when indoor relative humidity stays between 30% and 50%. When a home has high indoor humidity, the air feels warmer, denser and stickier—even if the actual air temperature is cool.
Too much indoor 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 cooling the air without extracting enough moisture.
Home Feels Humid? Here are 8 Common Causes
Living in Sandpoint, Idaho, muggy conditions can be a frequent concern.
Many area homeowners wonder the same question: Why does my house feel humid?
There could be multiple reasons. Identifying what's creating excess moisture is a good first step toward resolving the problem.
Below are several common reasons for elevated indoor humidity in Sandpoint, Idaho:
AC is Too Large
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. Dirty Air Filter
A blocked air filter reduces airflow throughout your heting and cooling system. This makes it challenging for your equipment to remove moisture while cooling your home.
3. Blocked Condensate Drain
Your AC removes moisture from your home’s air and drains it outside through a condensate line. If that drain becomes blocked, moisture can't leave the system properly, contributing to excess moisture indoors.
4. Dirty Evaporator Coil
The evaporator coil extracts both heat and moisture from your home's air supply. Dirt buildup on the coil reduces its effectiveness and often requires professional AC repair services to restore performance.
5. Leaky Ductwork
Ductwork transports cool air throughout your living space. Leaks in ductwork can allow warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This additional moisture makes it harder to maintain comfortable humidity levels.
6. Thermostat Fan Set to “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 is finished. This can blow 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 very humid summer weather, your HVAC system has to work harder to remove moisture from the air. Even when your air conditioner 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 home comfort systems wear out over time, they often become less efficient at controlling humidity. HVAC maintenance optimizes performance, improves efficiency and helps identify worn-out parts. Neglecting regular air conditioning maintenance can limit performance, including your system's ability to reduce moisture.
Simple Checks to Make Before Scheduling an HVAC Technician
If your home feels humid, there are some simple things you can check before scheduling 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 HVAC air filter allows proper airflow, helping your system cool and dehumidify your home more efficiently.
- Make sure the thermostat fan is set to Auto. This allows moisture to drain away after each cooling cycle instead of being circulated back into your living spaces.
- Check to ensure your supply and return vents are open and not covered up. Rugs or furniture over the vents or closed vents can limit airflow throughout your home.
- Inspect for water around the indoor unit. Water near your AC equipment may indicate a clogged condensate drain or another drainage issue.
- Monitor how your air conditioner 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 try repairs with refrigerant, electrical components or system components. Do-it-yourself fixes 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. Compared with portable units that only remove humidity from one room or area, a whole-home dehumidifier works alongside your HVAC system to manage humidity throughout your entire house.
