Has your AC ever worked perfectly in the morning, but by the afternoon, your home starts feeling warmer? This is a common problem during a Texas summer when temperatures rise and your air conditioner has to work harder to keep up.
If you notice your AC not cooling properly during the hottest part of the day, there could be several reasons why. Paying attention to the warning signs can help you identify a problem before your AC stops working completely.
Why Your AC May Stop Cooling in the Afternoon
Your air conditioner naturally has to work harder when outdoor temperatures are at their highest. But if your system struggles to keep your home at the temperature set on your thermostat, something may be preventing it from working efficiently.
Your System Is Overworked
The hotter it gets outside, the harder your AC has to work to remove heat from your home. Your system will likely run for longer periods of time to maintain a comfortable indoor temperature.
Longer run times aren't necessarily a problem, but if your AC runs constantly and still can't keep your home cool, you may have an underlying issue.
You may notice:
- Rooms that stay warmer than others
- Longer cooling cycles
- Higher energy bills
- Temperatures that continue to rise indoors
An older system may have an especially difficult time keeping up with extreme outdoor temperatures.
Restricted Airflow
Your AC needs proper airflow to cool your home effectively. When airflow is restricted, your system has to work harder and may struggle to distribute cool air throughout your home.
Restricted airflow can be caused by:
- Dirty air filters
- Blocked vents
- Dirty coils
- Lack of routine maintenance
Replacing your air filter regularly is one of the easiest ways to help maintain proper airflow. If your system continues to have airflow problems, a professional inspection can help identify the cause.
Low Refrigerant
Refrigerants play an important role in the cooling process. If your system has a refrigerant leak or doesn't have the proper refrigerant charge, it might not be able to remove enough heat from your home.
A refrigerant problem can cause:
- Warm air coming from your vents
- Longer cooling cycles
- Ice forming on the system
- Higher energy usage
If you suspect a refrigerant issue, it's important to have a professional inspect your system.
Problems With the Outdoor Unit
Your outdoor condenser helps release the heat removed from your home. If the unit becomes dirty or is surrounded by grass, leaves, or other debris, airflow can become restricted.
This can make it more difficult for your AC to release heat, especially when outdoor temperatures are at their highest.
Keep the area around your outdoor unit clear and make sure there is enough space for air to move freely. If the unit is excessively dirty or isn't operating properly, it may be time to schedule professional service.
When It May Be Time for AC Service
If your air conditioner consistently struggles to cool your home during the hottest part of the day, don't wait until it stops working completely. An AC not cooling properly could be a sign of a larger problem.
If your AC is doing any of the following, it may be time to have your system checked:
- Blows warm air
- Runs constantly
- Struggles to reach the thermostat setting
- Has unusually high energy bills
- Makes strange noises
- Doesn't cool certain rooms properly
