AC High Humidity Repair in Katy, TX

In the Houston area, your air conditioner does more than cool—it removes humidity. When your Katy home feels sticky, muggy, or clammy even with the AC running, your system isn’t dehumidifying properly. TemperaturePro Katy-Cypress diagnoses humidity problems and restores the dry, comfortable air you expect.

Here’s what causes indoor humidity problems and how we fix them.

Why Your Home Feels Humid

• Oversized AC – A system too large cools quickly but shuts off before removing enough moisture.
• Low refrigerant – A leak reduces the system’s ability to pull humidity from the air.
• Dirty evaporator coil – Buildup hampers the coil’s dehumidifying function.
• Poor airflow – Restricted airflow reduces moisture removal.
• Oversized or leaky ducts – Pull humid attic air into the system.
• Thermostat fan set to “on” – Running the fan constantly re-evaporates moisture off the coil.

Why Humidity Control Matters Here

Gulf Coast humidity makes proper dehumidification essential for comfort and health. Excess indoor humidity feels warmer than it is, encourages mold and dust mites, and can damage wood and finishes. A common quick win: set your thermostat fan to “auto” rather than “on” so moisture drains off the coil instead of re-evaporating. Beyond that, we diagnose the system cause.
