When your air conditioner starts acting up—especially during a scorching Texas summer—it can be tempting to panic and immediately call for professional help. However, before reaching for the phone, there are several DIY AC troubleshooting tips you can try that might save you time, money, and a bit of stress.
Of course, if the issue persists, it’s always best to consult a professional like Justice Inc., one of the best HVAC companies in Corpus Christi, Texas. But first, here’s a guide to common AC issues and what you can do before calling in the experts.
1. Check the Thermostat Settings
It might seem obvious, but sometimes the simplest fixes are the most overlooked. Make sure your thermostat is set to “cool” and the temperature is set lower than the current room temperature. If your thermostat uses batteries, try replacing them. Faulty or dead batteries are a common reason for ACs not turning on.
If your thermostat is programmable or smart, ensure there are no incorrect settings or schedules preventing your AC from running properly.
2. Inspect the Air Filter
A dirty or clogged air filter can severely restrict airflow, reducing your AC’s efficiency and potentially causing it to shut down. Depending on your system and environment, filters should be changed every 1 to 3 months.
Slide out the filter and hold it up to the light—if you can’t see through it, it’s time for a replacement. Justice Inc. recommends regular filter changes to maintain air quality and extend the life of your HVAC system.
3. Examine the Circuit Breaker
If your AC won’t turn on at all, a tripped circuit breaker might be the culprit. Head to your electrical panel and see if any switches have flipped to the “off” position. If so, flip them back to “on.” Be cautious—if the breaker trips again shortly after resetting, it could indicate a more serious electrical problem, which is definitely a job for a professional like Justice Inc. in Corpus Christi, Texas.
4. Clear the Outdoor Unit
Your outdoor condenser unit needs proper airflow to function efficiently. Leaves, dirt, and debris can accumulate around it, restricting airflow and causing your AC to work harder or overheat.
Gently clear any debris from around the unit and clean the fins with a soft brush or vacuum. Make sure there’s at least two feet of clearance around all sides of the unit. Regular cleaning not only improves performance but can also prevent long-term damage.
5. Check for Ice Buildup
If your AC is running but not cooling properly, you may have ice on the coils. This can be caused by dirty filters, blocked vents, or low refrigerant levels. Turn off the system and allow it to thaw completely before restarting it.
If ice keeps forming, it’s time to call in the pros. Justice Inc. has skilled technicians ready to diagnose and fix any refrigerant or airflow issues your system may be experiencing.
6. Inspect Vents and Registers
Walk through your home and ensure all air supply and return vents are open and unblocked by furniture or curtains. Obstructed vents can reduce airflow and put unnecessary strain on your AC unit.
If some rooms are significantly warmer or cooler than others, there may be ductwork issues or imbalanced air distribution—both of which Justice Inc. can help diagnose.
7. Listen for Unusual Noises
Unusual sounds like grinding, squealing, or banging are usually signs that something isn’t right. These noises can indicate anything from loose components to motor issues. While you can note where and when the noise occurs, avoid trying to fix internal components yourself.
Instead, contact an experienced HVAC technician. In Corpus Christi, Justice Inc. is known for prompt and professional service and can quickly identify the source of the problem.
