Why Does My Home Feel Humid Even When The AC Is Running?
Your air conditioner is supposed to cool your home and remove excess moisture from the air. So if your home still feels humid even when the AC is running, it can be frustrating. High indoor humidity doesn’t just make your home uncomfortable. It can also lead to musty odors, warped wood, mold growth, and higher energy bills. If your home feels damp despite the AC doing its job, there’s likely an underlying issue that needs attention. Our HVAC professionals at Oliver are here to explain why it may be happening and how we can help.
Your AC May Be Oversized
Bigger isn’t always better when it comes to air conditioning. An oversized system will cool your home quickly, but it may shut off before it has enough time to properly remove humidity from the air. Air conditioners dehumidify as they run. If the system cycles on and off too quickly, it won’t complete a full moisture-removal cycle. This results in your home reaching the set temperature, but still feeling damp and uncomfortable.
If you suspect your system may be oversized, our team at Oliver can evaluate your system size and performance to determine whether adjustments or upgrades are needed.
Your AC Isn’t Running Long Enough
Even if your system isn’t oversized, short cycling can still occur due to thermostat issues, airflow restrictions, or mechanical problems. When your AC doesn’t run long enough, humidity levels remain high. In some cases, a faulty thermostat may be causing premature shut-offs. In other cases, restricted airflow from a clogged filter or dirty coil could be limiting performance.
An HVAC inspection from Oliver can identify what’s preventing your system from running efficiently and keeping humidity under control.
Your System Needs Maintenance
Routine maintenance plays a major role in humidity control. Dirty evaporator coils, clogged condensate drains, and low refrigerant levels can all interfere with your system’s ability to remove moisture from the air. If it’s been a while since your last AC tune-up, your AC may be struggling more than you realize. Regular professional maintenance helps ensure your system is cooling properly and removing humidity as designed.
Scheduling seasonal maintenance with Oliver helps protect your system, improve efficiency, and maintain indoor comfort throughout the summer.
There May Be Airflow or Duct Issues
If certain rooms feel more humid than others, airflow imbalances or ductwork problems may be the cause. Leaky ducts can allow humid outdoor air to enter your system. Poor airflow can prevent conditioned air from circulating properly. Humidity problems that seem isolated to certain areas of your home often require professional testing and system evaluation.
Your Home May Need Additional Humidity Control
In some climates, especially during peak summer months, your AC alone may not be enough to manage indoor humidity levels. A whole-home dehumidifier can work alongside your HVAC system to maintain balanced indoor moisture levels. This not only improves comfort but also helps protect your home’s structure and indoor air quality.
If your home consistently feels damp, Oliver can recommend solutions tailored to your home’s size, layout, and comfort needs.
