Common AC Issues We Identify
Even a well-maintained AC system can experience strain during hot summer months. Our team is here to prevent, diagnose, and fix problems ASAP.
A couople of the more common AC issues we encounter 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: Frozen coils usually mean something’s off—like restricted airflow or a refrigerant issue—both of which hinder cooling performance.
- Dirty or Clogged Filters: Poor air filter maintenance leads to reduced airflow and extra system strain—two major causes of future AC repairs.
- Electrical Failures: Issues like bad wiring, failing capacitors, or tripped breakers can stop your AC from turning on or running properly.
- Thermostat Problems: A failing thermostat might be to blame for cooling issues, even when the AC unit itself is working just fine.
- Drainage Issues: Blocked condensate lines may result in pooling water, damage to nearby surfaces, or an automatic system shutdown.
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
Not all AC issues are predictable—some rare ones lead to bigger headaches and higher costs. The good news is regular HVAC maintenance often spots them before they escalate.
Some of the less obvious Fenton air conditioning 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: Small line leaks may not be obvious at first, but they gradually affect how well your system cools your space.
- Sensor Malfunctions: If a sensor isn’t reading correctly, your system might turn on or off at the wrong times, reducing comfort and control.
- Blower Motor Burnout: When the blower motor wears out from constant use, airflow stops. Regular maintenance helps catch signs of strain early.
Many of these issues develop slowly—but with proactive maintenance, you can address them before a full system breakdown leaves you in a hot house.

Signs You Might Need AC Repair
- Your AC keeps starting and stopping in short bursts.
- You’ve noticed a drop in airflow strength.
- Your system is making unusual noises like buzzing or banging.
- You see leaks or excessive moisture near the unit.
- Your indoor comfort level has declined without explanation.
These warning signs—big or small—are best handled early before they lead to more serious problems.
