Common Causes of High Indoor Humidity
High humidity levels inside your home can make it feel uncomfortable and even promote mold growth. If your AC isn’t effectively reducing humidity, there may be an underlying issue that needs attention. Addressing these problems quickly can help maintain a healthy and comfortable environment.
Incorrect AC Sizing
An air conditioner that’s too large for your home cools the air too quickly without removing excess moisture. This leaves the air feeling damp and sticky. A properly sized AC system can help prevent humidity issues.
Dirty or Clogged Coils
Evaporator coils covered in dirt can’t effectively dehumidify the air. Cleaning or replacing the coils can restore the system’s ability to reduce moisture.
Poor Ventilation
Improperly sealed or blocked vents can trap humid air indoors. Ensuring proper ventilation and airflow can significantly reduce moisture levels in your home.
Malfunctioning Thermostat
If the thermostat isn’t accurately reading humidity levels, your AC may not run long enough to dehumidify the air. Calibrating or replacing the thermostat can resolve this issue.
Refrigerant Issues
Low refrigerant levels can impair the AC’s ability to cool and dehumidify the air. A technician can check for leaks and refill the refrigerant as needed.
How to Reduce Indoor Humidity
Before calling a professional, you can try these simple steps to manage humidity levels. While DIY fixes can help in some cases, persistent problems may require expert HVAC service.
Use a Dehumidifier
If your AC isn’t effectively reducing humidity, a standalone dehumidifier can help remove excess moisture from the air.
Replace Air Filters
Dirty filters restrict airflow and reduce the system’s efficiency, impacting its ability to dehumidify. Replacing filters can improve performance.
Seal Windows and Doors
Humidity can enter through gaps around windows and doors. Sealing these gaps can help maintain lower indoor humidity levels.
Set the Thermostat to AUTO
Using the AUTO setting instead of ON allows the AC to dehumidify more effectively by running cycles as needed.
Inspect the Drain Line
A clogged condensate drain line can trap moisture inside the system. Clearing it can restore proper dehumidification.
When to Call an HVAC Company
If humidity issues persist despite troubleshooting, it’s time to contact a local HVAC repair company. Ignoring high humidity can lead to larger problems, including mold growth and system damage.
Consistently High Humidity
If your home feels damp all the time, professional service can identify and fix the root cause of the problem.
Mold or Mildew Growth
Visible mold or a musty smell indicates excess moisture in the air. A technician can address system issues contributing to the problem.
AC Running Constantly
If your AC is running nonstop but not reducing humidity, it may need a refrigerant refill or component repair.
Water Pooling Around the Unit
Excess water around your AC could indicate a clogged drain or other malfunction affecting dehumidification.
