The hot and humid summers in Newport, North Carolina, can get muggy and uncomfortable. You set the thermostat to a ideal temperature. The air conditioner kicks on automatically. But, even after your cooling system operates, your home still feels humid and uncomfortable.
That’s not very comfortable.
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 in good company. Many area homeowners have this problem.
The reason is simple: Temperature and humidity are two different factors in indoor comfort. A temperature only tells you how warm or cool the air is within the space. It doesn't measure how much moisture is in the air. When moisture levels are extremely 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 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 Newport, North Carolina, home. That way, you’ll know when to call experts like the team at Antonelli Comfort Solutions for expert assistance.
Why Your Home Can Feel Humid Even When the Temperature Is Right
Indoor temperature is only part of what makes your house enjoyable. Indoor humidity is an extremely important consideration. The majority of homes are the most comfortable when indoor relative humidity stays between 30% and 50%. When a home has high indoor humidity, the air feels hotter, more oppressive 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 lowering the temperature of the air without removing enough moisture.
8 Common Reasons Your Home Feels Humid
Residing in Newport, North Carolina, high humidity can be a problem.
Countless area homeowners wonder the same question: Why does my house feel humid?
There could be multiple reasons. Identifying what's creating humidity problems is the best place to start toward fixing the problem.
Below are several common reasons for indoor humidity problems in Newport, North Carolina:
Oversized Air Conditioning
1. Oversized Air Conditioning
An AC that's too big for your home cools your home too quickly. The problem is an oversized AC often doesn’t eliminate humidity effectively because it shuts off before completing a full cooling cycle.
2. Dirty Air Filter
A clogged air filter limits airflow throughout your HVAC system. This makes it harder for your equipment to control humidity while cooling your home.
3. Obstructed Condensate Drain
Your air conditioner removes moisture from the air in your home and drains it outside through a condensate line. If that drain becomes clogged, moisture can't exit the system properly, contributing to increased humidity levels.
4. Icy Evaporator Coil
The evaporator coil extracts both heat and moisture from your home's air supply. Dirt buildup on the coil reduces its effectiveness and often requires professional AC repair services to restore performance.
5. Loose Ductwork
Ductwork carries cool air throughout your living space. Gaps in ductwork can draw warm, humid air from attics, crawl spaces or other unconditioned areas into your HVAC system. This extra moisture makes it more difficult to maintain comfortable humidity levels.
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. Unusually Humid Weather
During the area’s extremely humid summers, your HVAC system has to work harder to remove moisture from the air. Even when your cooling system is functioning as designed, 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 home comfort systems age, they often become less effective at controlling humidity. HVAC maintenance improves performance, boosts efficiency and helps find worn-out parts. Neglecting regular air conditioning maintenance can decrease performance, including your system's ability to remove moisture.
Things to Check Before Scheduling an HVAC Technician
If your home feels humid, there are some 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.
- Check your HVAC air filter. A clean heating and cooling system air filter allows proper airflow, helping your system cool 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.
- Make sure supply and return vents are open and unobstructed. Rugs or furniture 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 suggest a clogged condensate drain or another drainage-related issue.
- Know how your air conditioner should run. If the AC is short cycling or turning on and off continuously, 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 try repairs involving refrigerant, electrical components or system components. Do-it-yourself fixes may be tempting, but these repairs require advanced 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. As opposed to portable units that only work in one room or area, a whole-home dehumidifier connects to your HVAC system to reduce humidity throughout your entire house.
