Common AC Issues We Identify
Even a well-maintained AC system can experience strain during hot summer months. Our team is here to prevent, diagnose, and fix problems ASAP.
A few of the more common AC issues we come across include:
- Low Refrigerant Levels: When refrigerant is low, a leak is the cause. We can recharge minor leaks, but major ones need to be sealed before the system can be refilled.
- Frozen Evaporator Coils: Frozen coils usually mean something’s off—like restricted airflow or a refrigerant issue—both of which hinder cooling performance.
- Dirty or Clogged Filters: Dust and debris in your filter reduce system airflow, lower efficiency, and add wear to key components.
- Electrical Failures: Your system may fail to start or cool correctly if components like capacitors or breakers are worn or malfunctioning.
- Thermostat Problems: A failing thermostat might be to blame for cooling issues, even when the AC unit itself is working just fine.
- Drainage Issues: Condensate line clogs are a common culprit behind unexpected shutdowns or hidden water damage near your unit.
We focus on fast turnarounds and fair pricing to restore your comfort. Connect with our HVAC experts for more info or help.
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 the less obvious St. Louis Hills AC issues include:
- Compressor Failure: The compressor is your system’s core component—when it fails, cooling stops. Regular checks can catch wear before it leads to major repairs.
- Refrigerant Line Damage: Pinhole leaks are easy to miss but can steadily reduce your system’s cooling ability over time.
- Sensor Malfunctions: Faulty sensors can throw off your system’s timing and airflow, leading to performance problems and wasted energy.
- Blower Motor Burnout: A burned-out motor means no air movement. Routine checkups can ease the load or flag problems before failure happens.
Small issues can snowball into major failures. With scheduled maintenance, you can stay ahead of system breakdowns and keep your home cool.

Signs You Might Need AC Repair
- Short bursts of cooling instead of consistent operation.
- Noticeably reduced airflow from your registers.
- Unusual sounds—anything from buzzing to banging.
- Leaks or excess water collecting around the system.
- Your AC doesn’t seem to cool as well as it used to.
These warning signs—big or small—are best handled early before they lead to more serious problems.
