AC Not Cooling Like It Used To? Here’s What Might Be Wrong

If your air conditioner isn’t cooling your home like it used to, you’re not alone. As the temperatures rise in Arlington, Texas, and across the Dallas-Fort Worth metroplex, it can be frustrating when your AC doesn’t perform at its peak. Whether you’re dealing with a minor inconvenience or a major breakdown, understanding the potential issues can help you get your system back in working order quickly.

Here’s a look at the most common reasons why your AC might not be cooling like it used to and how Texas Air Authorities can help.

1. Dirty Air Filters

One of the simplest and most common causes of poor cooling is dirty air filters. Over time, your air filter can become clogged with dust, dirt, and debris, obstructing airflow and forcing your AC system to work harder. This reduces efficiency and can lead to insufficient cooling.

Solution: Regularly replace or clean your air filters every 1-3 months. If you’re unsure when your filters need to be changed, our technicians at Texas Air Authorities can assess the situation and ensure your air filters are in good shape.

2. Low Refrigerant Levels

Refrigerant is essential to the cooling process, and if there’s a leak or low refrigerant levels, your AC will struggle to cool the air. A decrease in refrigerant may also indicate a leak somewhere in your system, which needs professional attention.

Solution: If you suspect a refrigerant issue, call our experienced technicians for a diagnostic. We’ll check the refrigerant levels, identify any leaks, and recharge the system if needed. As NATE-certified professionals, we handle all types of refrigerant-related problems with precision and care.

3. Dirty Coils

Both the evaporator and condenser coils in your AC are critical to its operation. Over time, dirt and debris can accumulate on these coils, making it harder for them to absorb and release heat. When the coils are dirty, your system may freeze up or fail to cool effectively.

Solution: Routine HVAC maintenance and tune-ups can help prevent this problem. Our experts at Texas Air Authorities offer comprehensive maintenance services, which include coil cleaning and other essential tasks to keep your AC running smoothly.

4. Frozen Evaporator Coil

A frozen evaporator coil can occur if the air filter is clogged, the refrigerant level is low, or if airflow is restricted. When the coil freezes, the system won’t be able to cool the air properly.

Solution: If you notice ice buildup on your AC unit, turn it off immediately to prevent further damage. Our technicians will inspect the evaporator coil, thaw it out, and address the root cause of the freezing.

5. Thermostat Issues

Sometimes, the issue isn’t with the AC system at all but with the thermostat. If your thermostat is malfunctioning or incorrectly calibrated, it might not be communicating with your AC unit, causing it to operate inefficiently or inaccurately.

Solution: If you’re experiencing inconsistent temperatures or your thermostat seems off, it might be time for a thermostat calibration or replacement. Texas Air Authorities can inspect and repair or replace your thermostat to restore precise temperature control.

6. Aging AC System

Air conditioners typically last 10-15 years, and as your system ages, its efficiency naturally declines. Older units may struggle to cool effectively and could need frequent repairs. If your AC is showing signs of age, it might be time to consider a replacement.

Solution: If your AC unit is approaching or has exceeded its expected lifespan, it’s worth considering a replacement. Our team offers free estimates for new AC installations, and we work with trusted brands like Lennox, Trane, and Goodman to ensure you get a reliable, energy-efficient system.

7. Lack of Regular Maintenance

Preventative maintenance is the key to keeping your HVAC system running efficiently. Neglecting annual HVAC maintenance can lead to unexpected breakdowns, poor performance, and higher energy bills.

Solution: Schedule regular HVAC maintenance and tune-ups to keep your system in top shape. Texas Air Authorities offer service contracts that include routine checkups, ensuring your system is ready for every season. By investing in maintenance, you can extend the lifespan of your AC and prevent costly repairs.

8. Leaking Ductwork

Leaking ducts can cause your AC to lose cool air before it reaches the desired rooms in your home. If your ducts are old or damaged, you may experience uneven cooling or an overall decrease in efficiency.

Solution: Our team can inspect your ductwork for leaks, blockages, or other issues. We offer professional duct services to seal leaks and ensure your AC is cooling your home effectively.

Conclusion

When your air conditioner isn’t cooling like it used to, the cause could be something as simple as a dirty filter or as complex as a refrigerant leak or aging system.
