The humid summers in Bend, Oregon, 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 damp and sticky.
Now, you’re cool and damp.
It can be frustrating 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? Temperature and humidity are two different measurements in your home. Your temperature only tells you how hot or cold the air is within the space. It doesn't measure how much humidity is in your home. When moisture levels are very 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 home 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 Bend, Oregon, home. That way, you’ll know when you should contact experts like the team at Tri County Climate Control LLC for support.
Why a Home Can Feel Humid Even Though the Temperature Is Right
Your home's temperature is only part of what makes your home comfortable. The amount of moisture in the air is another important consideration. Most homes are generally more comfortable when indoor relative humidity is 30-50 percent. When a home has high indoor humidity, the air feels less comfortable, more oppressive and stickier—even if the actual air temperature is cool.
Excess 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 cooling the air without pulling out enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Living in Bend, Oregon, high humidity can be a problem.
Countless area homeowners ask the same question: What's making my house feel humid?
There are several common causes. Understanding what's creating humidity problems is a good first step toward solving the problem.
Here are several common reasons for indoor humidity problems in Bend, Oregon:
1. Oversized Air Conditioning
An AC unit that's too big for your home cools down your home too quickly. The problem is an oversized AC often doesn’t eliminate humidity effectively because it stops operating before completing a proper cooling cycle.
2. Clogged Air Filter
A blocked air filter restricts airflow throughout your heting and cooling system. This makes it more difficult for your equipment to remove moisture while cooling your home.
3. Obstructed 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 higher indoor humidity.
4. Dirty Evaporator Coil
The evaporator coil removes both heat and moisture from your home's indoor air. Dirt buildup on the coil reduces its effectiveness and often requires professional AC repair services to fix.
5. Leaky Ductwork
Ductwork moves cool air throughout your house. Openings in ductwork can pull 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 Running on “On” Change setting to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower continues running after the cooling cycle is finished. This can blow moisture collected on the evaporator coil back into your home instead of allowing it to drain away.
7. Exceptionally Humid Weather
During the area’s extremely 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 continually enters your home through doors, windows and normal air leakage.
8. Poorly Maintained HVAC Equipment
As HVAC systems get older, they often become less capable at controlling humidity. HVAC maintenance enhances performance, boosts efficiency and helps identify worn-out parts. Neglecting regular air conditioning maintenance can limit performance, including your system's ability to control moisture.
Things to Check Before Contacting an HVAC Technician
If your home feels humid, there are some simple things you can check before scheduling service. These simple troubleshooting steps are easy ways to improve indoor comfort by helping your AC or heating system remove moisture more efficiently.
- Replace or inspect the air filter. A clean HVAC air filter allows proper airflow, helping your system circulate air through and dehumidify your home better.
- Verify the thermostat fan is set to Auto. This allows moisture to drain away after each cooling cycle instead of being sent back into your living spaces.
- Check that supply and return vents are open and unobstructed. Furniture over the vents or closed vents can reduce airflow throughout your home.
- Inspect for water around the indoor unit. Water by your AC equipment may signal a clogged condensate drain or another drain problem.
- Know 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, 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 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.
