Common AC Issues We Identify
Even well-cared-for AC systems can struggle when the heat hits hard. That’s where we come in—with fast diagnostics and effective repairs.
A few of the more common AC issues we come across include:
- Low Refrigerant Levels: If your AC is low on refrigerant, it’s due to a leak. Smaller leaks can be handled with a refill, but bigger ones must be fixed before recharging.
- Frozen Evaporator Coils: When airflow is blocked or refrigerant runs low, your coils can freeze—cutting down your system’s cooling power.
- Dirty or Clogged Filters: Restricted filters force your system to work overtime, reducing performance and increasing the risk of future damage.
- Electrical Failures: Your system may fail to start or cool correctly if components like capacitors or breakers are worn or malfunctioning.
- Thermostat Problems: The trouble might not be your AC system at all—just a malfunctioning thermostat that needs repair or replacement.
- Drainage Issues: When the drain line backs up, it can cause leaks or even force the system to shut down to prevent water damage.
We’re here to get your system running again quickly and affordably. Contact our HVAC experts if you have any questions.
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 the less obvious Florissant 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: Pinhole leaks are easy to miss but can steadily reduce your system’s cooling ability over time.
- Sensor Malfunctions: Faulty sensors may misread temperature or airflow, causing improper cycling or inefficiency.
- 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.
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
- Frequent on-off cycling that interrupts cooling.
- Weaker airflow coming from your vents.
- Odd sounds such as rattling, humming, or knocking.
- Pooled water or visible condensation around the AC unit.
- Your space just doesn’t feel as cool or balanced as it should.
These warning signs—big or small—are best handled early before they lead to more serious problems.
