The hot and humid summers in Winnipeg, Manitoba, can get muggy and uncomfortable. You adjust the thermostat to a ideal temperature. The air conditioner starts up automatically. But, even after your air conditioner cycles, your home still feels moist and clammy.
Now, you’re cool and damp.
It can be frustrating when the air conditioner appears to work properly, yet your home doesn't actually feel comfortable. If your rooms feel humid but thermostat says cool, you're not alone. It happens a lot.
Why? Temperature and humidity are two different things. Your temperature only tells you how comfortable the air is within the space. It doesn't measure the amount of moisture in the air. When humidity levels are 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 home comfort, common reasons your home feels humid even when the temperature is correct and easy troubleshooting steps you can try to reduce humidity in your Winnipeg, Manitoba, home. That way, you’ll know when you should call experts like the team at Kirkfield Heating & Air Conditioning for support.
Why Your Home Can Feel Humid Even Though the Temperature Is Cool
Your home's temperature is only part of what makes your living space comfortable. The amount of moisture in the air is an extremely important element to consider. The majority of homes are typically more comfortable when indoor relative humidity stays in the 30-50% range. When a home has high indoor humidity, the air feels less comfortable, 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 lowering the temperature of the air without extracting enough moisture.
8 Common Reasons Your Home Feels Humid
Residing in Winnipeg, Manitoba, high humidity can be a challenge.
Countless area homeowners wonder the same question: What's making my house feel humid?
There are a variety of common explanations. Understanding what's creating high idoor humidity is a good first step toward fixing the problem.
Below are several common reasons for elevated indoor humidity in Winnipeg, Manitoba:
1. AC is Too Large
An AC that's larger than your home actually needs lowers the temperature in your home too quickly. The problem is an oversized AC often doesn’t reduce humidity effectively because it stops operating before completing a full cooling cycle.
2. Blocked Air Filter
A blocked air filter limits airflow throughout your HVAC system. This makes it more difficult for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioner pulls out moisture from your indoor air and drains it outside through a condensate line. If that drain becomes blocked, moisture can't exit the system properly, contributing to increased humidity levels.
4. Dirty Evaporator Coil
The evaporator coil removes both heat and moisture from your home's air. Ice formation or excessive dirt on the coil limits its effectiveness and often requires professional AC repair services to fix.
5. Loose Ductwork
Ductwork transports cool air throughout your house. Openings in ductwork can pull warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This added moisture makes it more challenging to maintain comfortable humidity levels.
6. Thermostat Fan Running on “On” Switch to “Auto”
If your thermostat fan is set to "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. Extremely Humid Weather
During the area’s extremely humid and hot summers, 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 continues to seep into your home through doors, windows and normal air leakage.
8. Aging Heating and Cooling Equipment
As heating and cooling systems age, they often become less efficient at controlling humidity. HVAC maintenance optimizes performance, boosts efficiency and helps detect worn-out parts. Neglecting regular air conditioning maintenance can decrease performance, including your system's ability to control moisture.
Simple Checks to Make Before Scheduling an HVAC Technician
If your home feels humid, there are a few simple things you can check before booking service. These strategies are easy ways to improve indoor comfort by helping your HVAC system remove moisture more efficiently.
- Check your HVAC air filter. A clean heating and cooling system 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 flow out after each cooling cycle instead of being sent 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 limit airflow throughout your home.
- Look for water around the indoor unit. Water near your AC equipment may indicate a clogged condensate drain or another drainage issue.
- Monitor 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 attempt 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 left to a qualified HVAC technician.
Does Your Home Need 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. Unlike portable units that only help reduce moisture in one room or area, a whole-home dehumidifier connects to your HVAC system to manage humidity throughout your entire house.
