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 couople 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: 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: If water can’t drain properly, your AC may leak or switch off entirely as a protective measure.
We focus on fast turnarounds and fair pricing to restore your comfort. Connect with our HVAC experts for more info or help.
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 Frontenac air conditioning issues include:
- Compressor Failure: A failing compressor usually means serious repair or replacement. Regular service helps spot trouble before it gets expensive.
- Refrigerant Line Damage: Tiny pinhole leaks can slowly reduce system efficiency, often going unnoticed until your home isn’t cooling properly.
- Sensor Malfunctions: Bad readings from damaged sensors can cause your AC to cycle too often—or not enough—hurting efficiency.
- Blower Motor Burnout: Overworked motors can burn out. Preventative care can relieve stress or predict failure before your system stops working.
These problems often start small—but with regular maintenance, you can fix them before they turn into full-blown system failures.

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.
