The warm summers in Thedford, Ontario, can get muggy and uncomfortable. You set the thermostat to a pleasant temperature. The air conditioner starts up as expected. But, even after your AC cycles, your home still feels moist and clammy.
That’s not very comfortable.
It can be annoying when the air conditioner seems to operate normally, yet your home doesn't actually feel comfortable. If your rooms feel humid but thermostat says cool, you're not the only homeowner. Local homeowners often have this experience.
The reason is simple: 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 too high, your home can feel warmer than the thermostat indicates, due to indoor humidity problems.
In this blog, you'll learn how humidity affects your indoor comfort levels, common reasons your home feels humid even when the temperature is right and easy troubleshooting steps you can try to reduce humidity in your Thedford, Ontario, home. That way, you’ll know when to reach out to experts like the team at Taylor's Heating & Air Conditioning for expert assistance.
Why a Home Can Feel Humid Even When the Temperature Is Cool
Indoor temperature is only part of what makes your house enjoyable. Indoor humidity is also an equally important element to consider. Many homes are generally more comfortable when indoor relative humidity stays in the 30-50% range. 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 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 chilling the air without extracting enough moisture.
Home Feels Humid? Here are 8 Common Causes
Making your home 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 several common causes. Identifying what's creating high idoor humidity is the best place to start toward solving the problem.
Let's look at several common reasons for indoor humidity problems in Thedford, Ontario:
Oversized Air Conditioning
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 remove humidity effectively because it turns off before completing a proper cooling cycle.
2. Dirty Air Filter
A clogged air filter limits airflow throughout your heting and cooling system. This makes it more difficult for your equipment to control humidity while cooling your home.
3. Clogged Condensate Drain
Your air conditioning pulls out 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 exit the system properly, contributing to excess moisture indoors.
4. Frozen Evaporator Coil
The evaporator coil pulls both heat and moisture from your home's air supply. Dirt and grime on the coil limits its effectiveness and often requires professional AC repair services to fix.
5. Damaged Ductwork
Ductwork carries cool air throughout your home. Openings in ductwork can draw warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This added moisture makes it harder to maintain comfortable humidity throughout your home.
6. Thermostat Fan Set to “On” Change setting to “Auto”
If your thermostat fan is running on "On" instead of "Auto", the blower keeps running after the cooling cycle completes. This can push moisture collected on the evaporator coil back into your home instead of allowing it to drain away.
7. Extremely Humid Weather
During the area’s very humid summer weather, your HVAC system has to operate more to remove moisture from the air. Even when your air conditioner is working properly, sometimes your home feels muggy because outdoor humidity continually enters your home through doors, windows and normal air leakage.
8. Aging Heating and Cooling Equipment
As heating and cooling systems wear out over time, they often become less efficient at controlling humidity. HVAC maintenance optimizes performance, increases efficiency and helps identify worn-out parts. Putting off 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 house feels humid, there are a few simple things you can check before booking service. These DIY tips are easy ways to improve indoor comfort by helping your HVAC system remove moisture more efficiently.
- Replace or inspect the air filter. A clean HVAC air filter allows proper airflow, helping your system cool and dehumidify your home effectively.
- Verify 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.
- Make sure supply and return vents are open and unobstructed. Rugs or household furnishings over the vents or closed vents can reduce airflow throughout your home.
- Inspect for water around the indoor unit. Water around your AC equipment may signal a clogged condensate drain or another drainage issue.
- Pay attention to 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, it's time to have the system evaluated by a professional.
Even if your thermostat still says cool but house feels humid, do not try repairs with refrigerant, electrical components or internal HVAC parts. Handling these repairs yourself may be tempting, but these repairs require advanced training and should always be handled by a qualified HVAC technician.
Does Your Home Need 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 worth considering.
