The humid summers in Jefferson, Wisconsin, can get muggy and uncomfortable. You change the thermostat to a pleasant temperature. The air conditioner begins running automatically. But, even after your AC operates, your home still feels damp and sticky.
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.
Why is this? Temperature and humidity are two different factors in indoor comfort. Your temperature only tells you how warm or cool the air is within the room. It doesn't measure how much humidity is in your home. When humidity levels are too high, your home can feel warmer than the thermostat indicates, due to indoor humidity problems.
In this guide, you'll learn how humidity affects your comfort, common reasons your home feels humid even when the temperature is comfortable and basic troubleshooting steps you can try to reduce humidity in your Jefferson, Wisconsin, home. That way, you’ll know when to call experts like the team at Pratt Brothers for expert assistance.
Why a Home Can Feel Humid Even If the Temperature Is Right
The temperature is only part of what makes your living space enjoyable. Humidity is also an equally important element to consider. Many homes are typically more comfortable when indoor relative humidity stays 30-50 percent. When a home has high indoor humidity, the air feels warmer, more oppressive and stickier—even if the actual air temperature is cool.
High humidity can also promote dangerous mold growth, mildew, musty 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 pulling out enough moisture.
Reasons Your Home Feels Humid Even with the AC Running
Making your home in Jefferson, Wisconsin, excess moisture can be a challenge.
Many area homeowners deal with the same question: Why does my home feel so humid?
There are a variety of common explanations. Understanding what's creating excess moisture is a key first step toward solving the problem.
Let's look at several common reasons for high indoor humidity levels in Jefferson, Wisconsin:
AC is Too Large
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 eliminate humidity effectively because it stops operating before completing a full cooling cycle.
2. Dirty Air Filter
A dirty 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 indoor air and that excess water drains from the unit through a condensate line. If that drain becomes clogged, moisture can't drain from the system properly, contributing to increased humidity levels.
4. Frozen Evaporator Coil
The evaporator coil extracts both heat and moisture from your home's indoor air. 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 extra moisture makes it harder to maintain comfortable humidity throughout your home.
6. Thermostat Fan Set to “On” Change to “Auto”
If your thermostat fan is set to "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 giving it time for it to drain away.
7. Exceptionally Humid Weather
During the area’s especially humid summer weather, your HVAC system has to operate more to remove moisture from the air. Even when your cooling system 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 improves performance, improves efficiency and helps identify worn-out parts. Neglecting regular air conditioning maintenance can decrease performance, including your system's ability to reduce moisture.
Simple Checks to Make Before Contacting an HVAC Technician
If your house feels humid, there are some simple things you can check before booking service. These simple troubleshooting steps are easy ways to improve indoor comfort by helping your HVAC system remove moisture more efficiently.
- Replace a dirty air filter. A clean heating and cooling system 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 leave the system after each cooling cycle instead of being circulated back into your living spaces.
- Check to ensure your supply and return vents are open and unblocked. Rugs or furniture over the vents or closed vents can reduce airflow throughout your home.
- Check for water around the indoor unit. Water near your AC equipment may indicate a clogged condensate drain or another drain problem.
- Know how your air conditioning should run. If the AC is short cycling or turning on and off frequently, or it seems to run constantly without cooling your home like it should, 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 involving refrigerant, electrical components or internal parts. Do-it-yourself fixes may be tempting, but these repairs require specialized training and should always be handled by a qualified HVAC technician.
Does Your Home Need a Whole-Home Dehumidifier?
If you deal 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.
Just one of Pratt Brothers's indoor air quality solutions, a whole-home dehumidifier helps keep your home more comfortable while lowering the risk of mold, musty odors and excess moisture. It can be especially helpful for homes in damp climates or properties that still have humidity even with a properly functioning AC.
