Common AC Issues We Identify

Peak heat can challenge any AC system—even those in good shape. Our experts are ready to troubleshoot and make the right fix right away.

A couople of the more common AC issues we come across include:

  • Low Refrigerant Levels: A low level of refrigerant signals a leak—whether minor or major. Smaller issues might just need a recharge, but larger ones will need repair first.
  • Frozen Evaporator Coils: Low refrigerant or restricted airflow can lead to coil freeze-ups, making your AC far less effective at cooling your home.
  • Dirty or Clogged Filters: Poor air filter maintenance leads to reduced airflow and extra system strain—two major causes of future AC repairs.
  • Electrical Failures: Power-related problems—such as damaged wiring or faulty parts—can interrupt cooling or keep your system from starting at all.
  • Thermostat Problems: An inaccurate or unresponsive thermostat can cause erratic cooling or prevent your system from running altogether.
  • Drainage Issues: When the drain line backs up, it can cause leaks or even force the system to shut down to prevent water damage.

Getting your AC back online quickly and without a big bill—that’s what we do. Have questions? Talk to our HVAC experts.


Less Common AC Issues That Regular Maintenance Can Identify

While routine issues are common, less obvious AC problems can do more damage. Fortunately, regular HVAC maintenance helps catch those before they become serious.

Some of these less-obvious University City air conditioning issues include:

  • Compressor Failure: Your AC can’t cool without a working compressor. Early signs of damage can often be caught during routine inspections.
  • Refrigerant Line Damage: Small leaks in the refrigerant line can quietly drain performance—often going undetected until your AC stops cooling effectively.
  • Sensor Malfunctions: Misfiring sensors can disrupt normal operation, forcing the system to run inefficiently or inconsistently.
  • Blower Motor Burnout: A burned-out motor means no air movement. Routine checkups can ease the load or flag problems before failure happens.

These problems often start small—but with regular maintenance, you can fix them before they turn into full-blown system failures.
