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: Poor airflow or low refrigerant can cause your coils to freeze, reducing your system’s ability to cool the air.
  • Dirty or Clogged Filters: When filters get clogged, airflow drops, efficiency suffers, and your system has to work harder—often causing bigger problems later.
  • Electrical Failures: Faulty wiring, worn capacitors, or tripped breakers can prevent your system from powering on or cooling effectively.
  • Thermostat Problems: A failing thermostat might be to blame for cooling issues, even when the AC unit itself is working just fine.
  • Drainage Issues: A clogged condensate line can trigger safety shut-offs or lead to water damage around your system.

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 the less obvious Des Peres air conditioning issues include:

  • Compressor Failure: The compressor handles most of the system’s workload—routine maintenance can catch issues early and save you from a costly breakdown.
  • 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: When the blower motor wears out from constant use, airflow stops. Regular maintenance helps catch signs of strain early.

Left unchecked, many of these issues get worse with time. Maintenance helps you catch them early—before your home turns into an oven.
