AC Not Cooling in Katy, TX
If your air conditioner runs but the house stays warm, start with a few safe checks before contacting an HVAC technician.
Check the thermostat settings
Set the thermostat to cooling mode and select a temperature below the current room temperature. If the display is blank, consult its user manual for battery or power guidance.
Look at the air filter
A heavily clogged return-air filter can restrict airflow. If you can safely access the filter, replace it with the size and type recommended for your system.
Check supply and return vents
Make sure vents are not blocked by furniture or rugs. Weak airflow across multiple rooms can indicate a problem that needs professional diagnosis.
Notice ice or water
Ice on refrigerant lines or the indoor coil can signal restricted airflow or another system fault. Switch cooling off and arrange qualified service rather than chipping ice or handling refrigerant.
When to request HVAC help
If the unit blows warm air after basic checks, repeatedly shuts off, leaks near electrical components, or makes unusual noises, request an assessment from a qualified HVAC contractor.
Why is my AC running but not cooling?
Possible causes include thermostat settings, restricted airflow, frozen coils, or equipment faults. Only an on-site technician can determine the actual cause.
