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 encounter include:
- Low Refrigerant Levels: Refrigerant doesn’t get used up—it leaks out. If levels are low, we’ll find the leak and either recharge the system or repair it, depending on severity.
- Frozen Evaporator Coils: Ice on the coils often points to airflow problems or low refrigerant, both of which limit your system’s ability to cool efficiently.
- Dirty or Clogged Filters: Clogged air filters reduce efficiency and strain your system, often leading to bigger issues down the line.
- Electrical Failures: Faulty wiring, worn capacitors, or tripped breakers can prevent your system from powering on or cooling effectively.
- Thermostat Problems: Sometimes the issue isn’t the AC unit—it’s the thermostat. Repair or replacement may be needed.
- Drainage Issues: If water can’t drain properly, your AC may leak or switch off entirely as a protective measure.
It’s our job to get your system back online as quickly as possible at minimal cost. Contact our HVAC experts if you have any additional 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 Mehlville 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: Small leaks in the refrigerant line can quietly drain performance—often going undetected until your AC stops cooling effectively.
- 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.
Most of these problems don’t happen overnight. Routine service can spot trouble before it leads to a total breakdown and a hot, uncomfortable house.

Signs You Might Need AC Repair
- AC kicks on and off too often without running long enough.
- Less airflow through your ducts and vents.
- Strange or loud operational noises you haven’t heard before.
- Drips, puddles, or moisture near the air conditioner.
- It’s harder to keep your home comfortable like you used to.
These warning signs—big or small—are best handled early before they lead to more serious problems.
