Common AC Issues We Identify
No system is immune to the demands of summer heat. Our job is to identify problems early and resolve them quickly and reliably.
A couople of the more common AC issues we come across include:
- Low Refrigerant Levels: Low refrigerant means there’s a leak somewhere. Minor leaks may just need a recharge, but major ones require repair before topping off the system.
- 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: A clogged filter chokes off airflow, strains the system, and can trigger breakdowns if left unchecked.
- 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: When the drain line backs up, it can cause leaks or even force the system to shut down to prevent water damage.
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
Even though many AC issues are expected, rarer ones can cause real trouble. That’s why regular HVAC maintenance is key to staying ahead of them.
Some of the less obvious Ladue AC 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: When sensors misread airflow or temperature, your system may cycle at the wrong times or run inefficiently.
- 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.
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
- 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.
Even small issues can point to bigger trouble ahead, so it’s smart to act before they get worse.
