Common AC Issues We Identify
No system is immune to the demands of summer heat. Our job is to identify problems early and resolve them quickly and reliably.
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: A common result of airflow blockages or refrigerant loss, frozen coils prevent your system from properly lowering indoor temps.
- 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: Power-related problems—such as damaged wiring or faulty parts—can interrupt cooling or keep your system from starting at all.
- Thermostat Problems: An inaccurate or unresponsive thermostat can cause erratic cooling or prevent your system from running altogether.
- Drainage Issues: Condensate line clogs are a common culprit behind unexpected shutdowns or hidden water damage near your unit.
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 Clayton air conditioning 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: Faulty sensors may misread temperature or airflow, causing improper cycling or inefficiency.
- Blower Motor Burnout: A burned-out motor means no air movement. Routine checkups can ease the load or flag problems before failure happens.
Small issues can snowball into major failures. With scheduled maintenance, you can stay ahead of system breakdowns and keep your home cool.

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.
No matter how small they seem, these issues should be addressed quickly to avoid bigger headaches later.
