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 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: 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: When filters get clogged, airflow drops, efficiency suffers, and your system has to work harder—often causing bigger problems later.
- Electrical Failures: If the wiring’s damaged or a capacitor fails, your system might struggle to operate—or not start at all.
- Thermostat Problems: An inaccurate or unresponsive thermostat can cause erratic cooling or prevent your system from running altogether.
- Drainage Issues: If the condensate line gets clogged, it can cause water damage or shut down the system as a safety precaution.
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
Most AC problems are routine, but some less common ones can be costlier and more disruptive. The upside? Regular HVAC maintenance can catch many of them early.
Some of these less-obvious Ellisville AC issues include:
- Compressor Failure: As the heart of your AC system, the compressor plays a vital role in cooling. Regular inspections can detect strain or wear before a full breakdown.
- Refrigerant Line Damage: Small line leaks may not be obvious at first, but they gradually affect how well your system cools your space.
- Sensor Malfunctions: When sensors misread airflow or temperature, your system may cycle at the wrong times or run inefficiently.
- Blower Motor Burnout: Continuous strain can wear down the blower motor, but preventative service can help extend its life or catch issues before they escalate.
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
- Your system turns on and off frequently (short cycling).
- Airflow that has become noticeably weaker.
- Rattling, banging, buzzing, and other strange noises.
- Leaks and excess moisture around your AC unit.
- Your home isn’t as comfortable as usual.
Whether it’s a minor fix or a red flag for something bigger, these issues are worth addressing sooner rather than later.
