The hot and humid summers in Thedford, Ontario, can get muggy and uncomfortable. You adjust the thermostat to a comfortable temperature. The air conditioner starts up automatically. But, even after your cooling system operates, your home still feels moist and clammy.
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. It happens a lot.
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 the space. It doesn't measure the amount of moisture in the air. When moisture levels are very high, your home can feel much hotter than the thermostat indicates, due to indoor humidity problems.
In this blog, 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 Thedford, Ontario, home. That way, you’ll know when to contact experts like the team at Taylor's Heating & Air Conditioning for expert assistance.
Why Your Home Can Feel Humid Even If the Temperature Is Right
Indoor temperature is only part of what makes your house comfortable. The amount of moisture in the air is also an equally important consideration. The majority of homes are the most comfortable when indoor relative humidity falls 30-50 percent. When a home has high indoor humidity, the air feels less comfortable, heavier and stickier—even if the actual air temperature is cool.
Too much indoor moisture can also contribute to 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 removing enough moisture.
8 Common Reasons Your Home Feels Humid
Residing in Thedford, Ontario, high humidity can be a frequent concern.
Countless area homeowners ask the same question: What's making my house feel humid?
There are a variety of common explanations. Understanding what's creating excess moisture is the best place to start toward fixing the problem.
Below are several common reasons for indoor humidity problems in Thedford, Ontario:
1. Oversized Air Conditioner
An air conditioner that's bigger than your home needs cools your home too quickly. The problem is an oversized AC often doesn’t reduce humidity effectively because it turns off before completing a full cooling cycle.
2. Dirty Air Filter
A blocked air filter reduces airflow throughout your heting and cooling system. This makes it harder for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioning pulls out moisture from the air in your home and drains it outside through a condensate line. If that drain becomes clogged, moisture can't leave the system properly, contributing to higher indoor humidity.
4. Frozen Evaporator Coil
The evaporator coil removes both heat and moisture from your home's air supply. Dirt and grime on the coil decreases its effectiveness and often requires professional AC repair services to restore performance.
5. Loose Ductwork
Ductwork moves cool air throughout your house. Openings in ductwork can draw warm, humid air from attics, crawl spaces or other uninhabited areas into your HVAC system. This extra moisture makes it more difficult to maintain comfortable humidity levels.
6. Thermostat Fan is on “On” Setting Change setting to “Auto”
If your thermostat fan is set to "On" instead of "Auto", the blower continues running after the cooling cycle completes. This can blow moisture collected on the evaporator coil back into your home instead of giving it time for it to drain away.
7. Extremely Humid Weather
During the area’s very humid and hot summers, your HVAC system has to work harder to remove moisture from the air. Even when your AC is working properly, 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 heating and cooling systems wear out over time, they often become less effective at controlling humidity. HVAC maintenance improves performance, improves efficiency and helps identify worn-out parts. Skipping regular air conditioning maintenance can limit performance, including your system's ability to control moisture.
What You Can Check Before Calling an HVAC Technician
If your home feels humid, there are some simple things you can check before requesting service. These simple troubleshooting steps are easy ways to improve indoor comfort by helping your HVAC system remove moisture more effectively.
- Replace a dirty air filter. A clean HVAC air filter allows proper airflow, helping your system condition and dehumidify your home more efficiently.
- Make sure the thermostat fan is set to Auto. This allows moisture to leave the system after each cooling cycle instead of being circulated back into your living spaces.
- Make sure supply and return vents are open and not covered up. Rugs or furniture 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 signal a clogged condensate drain or another drain problem.
- Know how your AC should run. If the AC is short cycling or turning on and off repeatedly, or it seems to run constantly without cooling your home, it's time to have the system checked by a professional.
Even if your thermostat still says cool but house feels humid, do not perform repairs with refrigerant, electrical components or internal parts. Handling these repairs yourself may be tempting, but these repairs require professional training and should always be handled by a qualified HVAC technician.
Should You Get a Whole-Home Dehumidifier?
If you struggle with 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 connects to your HVAC system to control humidity throughout your entire house.
