When the Texas summer heat hits hard, there’s nothing worse than realizing your air conditioner isn’t keeping up. At Texas Air Authorities, we know that sometimes you can’t wait for a technician—especially when the temperatures soar into triple digits. While we’re always just a call away for same-day service, there are a few things you can check before a professional arrives. These quick troubleshooting tips can help you stay cool, prevent damage, and maybe even get your AC back up and running without a service call.
1. Check Your Thermostat Settings
It might sound simple, but thermostat issues are one of the most common culprits when your AC isn’t cooling. Make sure your thermostat is set to “cool” mode and that the temperature is set a few degrees lower than your current room temperature. If you have a programmable thermostat, verify that the schedule hasn’t been changed accidentally.
If your thermostat is battery-powered, replace the batteries and check if the screen lights up. A blank display could indicate that your thermostat isn’t communicating with the system—an easy fix you can do yourself.
2. Inspect the Air Filter
A dirty or clogged air filter can cause your AC to lose efficiency or even stop working altogether. When airflow is restricted, your system must work harder to push air through, which can cause freezing on the coils or overheating in the motor.
Remove your filter and hold it up to a light. If you can’t see through it, it’s time for a replacement. Ideally, filters should be changed every 30 to 90 days, depending on usage, pets, and indoor air quality.
3. Make Sure the Power Is On
It might seem obvious, but sometimes the issue comes down to a flipped breaker or a power switch that’s been turned off. Check both your indoor air handler and outdoor condenser unit.
- Locate your electrical panel and make sure no breakers are tripped. If you find one, reset it by turning it off completely and then back on.
- Many outdoor units have a small disconnect box mounted nearby—ensure it’s switched to the “on” position.
If the breaker keeps tripping, don’t force it. This could indicate an electrical issue that requires a certified HVAC technician.
4. Inspect the Outdoor Unit
Head outside and take a look at your condenser (the big metal box with a fan). Make sure it’s free of debris—grass clippings, leaves, dirt, and even nesting critters can block airflow.
If the fins look clogged, turn off the power and gently rinse them with a garden hose from the inside out. Avoid using high pressure, as this can bend the fins. Keeping the area around your unit clear ensures proper ventilation and helps your AC cool more effectively.
5. Check for Ice on the Coils
If your AC seems to be running but blowing warm air, frozen coils might be the cause. Open your indoor unit’s access panel and look for frost or ice buildup. If you see any, turn off the system immediately and set the fan to “on.” This helps thaw the ice and can prevent further damage.
Once the coils are thawed, replace your air filter if it’s dirty and make sure vents are open and unobstructed. If the problem continues, there may be a refrigerant leak or airflow issue that requires professional attention.
6. Examine Air Vents and Registers
Blocked or closed vents can create uneven cooling or cause your system to short cycle. Go room to room and ensure all vents are open and not covered by furniture, rugs, or curtains. Balanced airflow is key to maintaining comfort and system efficiency.
7. Give It a Break
If your AC has been running non-stop on a 100-degree day, it might just be struggling to keep up. Turn the thermostat up a few degrees to reduce strain on the system. Running ceiling fans and keeping blinds closed during the hottest part of the day can help your home stay comfortable without overworking your unit.
