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: If refrigerant is low, there is a leak. A minor leak can be addressed by adding refrigerant while a major leak will need to be repaired before recharging the system.
- 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: Restricted filters force your system to work overtime, reducing performance and increasing the risk of future damage.
- Electrical Failures: Faulty wiring, worn capacitors, or tripped breakers can prevent your system from powering on or cooling effectively.
- Thermostat Problems: When your thermostat isn’t communicating properly, it can throw off the entire system. Repair or a new unit may be needed.
- Drainage Issues: A clogged condensate line can trigger safety shut-offs or lead to water damage around your system.
Fast, affordable AC repair is what we’re known for. Contact our HVAC team anytime with questions or concerns.
Less Common AC Issues That Regular Maintenance Can Identify
Some AC problems are easy to fix, while others are hidden and costly. The good news? Ongoing HVAC maintenance helps detect them early.
Some of the less obvious Ballwin 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: When refrigerant leaks from hairline cracks in the line, efficiency drops—often without you noticing until comfort starts slipping.
- Sensor Malfunctions: Bad readings from damaged sensors can cause your AC to cycle too often—or not enough—hurting efficiency.
- Blower Motor Burnout: If the blower motor gives out, your system can’t circulate air. Maintenance reduces stress and helps spot early warning signs.
Left unchecked, many of these issues get worse with time. Maintenance helps you catch them early—before your home turns into an oven.

Signs You Might Need AC Repair
- The system short cycles—turning off and on repeatedly.
- Vents are blowing with less force than usual.
- Noises like rattles, buzzes, or bangs coming from the unit.
- Leaks or damp spots appearing near your equipment.
- Your home feels warmer or more humid than it should.
Whether it’s a quick adjustment or something more serious, catching these problems early saves time and money.
