Common AC Issues We Identify

When summer temperatures rise, even a tuned-up AC can run into trouble. We’re here to catch and correct issues before they get worse.

A few of the more common AC issues we encounter 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: When airflow is blocked or refrigerant runs low, your coils can freeze—cutting down your system’s cooling power.
  • Dirty or Clogged Filters: Clogged air filters reduce efficiency and strain your system, often leading to bigger issues down the line.
  • Electrical Failures: If the wiring’s damaged or a capacitor fails, your system might struggle to operate—or not start at all.
  • Thermostat Problems: If your thermostat is faulty, your AC won’t know when—or how long—to run. A quick fix or replacement may solve everything.
  • Drainage Issues: Condensate line clogs are a common culprit behind unexpected shutdowns or hidden water damage near your unit.

Our goal is fast, cost-effective AC repair that gets your system back on track. Reach out to our HVAC experts if you have questions.


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 Sappington AC issues include:

  • Compressor Failure: This high-stress part drives your entire cooling system. Catching electrical or mechanical issues early can prevent total failure.
  • Refrigerant Line Damage: When refrigerant leaks from hairline cracks in the line, efficiency drops—often without you noticing until comfort starts slipping.
  • Sensor Malfunctions: If a sensor isn’t reading correctly, your system might turn on or off at the wrong times, reducing comfort and control.
  • Blower Motor Burnout: These motors do a lot of heavy lifting—and can fail without warning. Inspections can help you avoid sudden loss of airflow.

A lot of AC issues build over time. With proactive maintenance, you can stop them before your system shuts down on a sweltering day.
