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 couople of the more common AC issues we come across include:
- Low Refrigerant Levels: When refrigerant is low, a leak is the cause. We can recharge minor leaks, but major ones need to be sealed before the system can be refilled.
- Frozen Evaporator Coils: A common result of airflow blockages or refrigerant loss, frozen coils prevent your system from properly lowering indoor temps.
- Dirty or Clogged Filters: Dust and debris in your filter reduce system airflow, lower efficiency, and add wear to key components.
- Electrical Failures: Power-related problems—such as damaged wiring or faulty parts—can interrupt cooling or keep your system from starting at all.
- Thermostat Problems: A failing thermostat might be to blame for cooling issues, even when the AC unit itself is working just fine.
- 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
While routine issues are common, less obvious AC problems can do more damage. Fortunately, regular HVAC maintenance helps catch those before they become serious.
Some of these less-obvious Brentwood 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 can throw off your system’s timing and airflow, leading to performance problems and wasted energy.
- Blower Motor Burnout: Overworked motors can burn out. Preventative care can relieve stress or predict failure before your system stops working.
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.
