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: Low refrigerant means there’s a leak somewhere. Minor leaks may just need a recharge, but major ones require repair before topping off 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: A clogged filter chokes off airflow, strains the system, and can trigger breakdowns if left unchecked.
- Electrical Failures: Your system may fail to start or cool correctly if components like capacitors or breakers are worn or malfunctioning.
- Thermostat Problems: A failing thermostat might be to blame for cooling issues, even when the AC unit itself is working just fine.
- Drainage Issues: Condensate line clogs are a common culprit behind unexpected shutdowns or hidden water damage near your unit.
Our goal is fast, cost-effective AC repair that gets your system back on track. Reach out to our HVAC experts if you have questions.
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 these less-obvious Richmond Heights 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: Pinhole leaks are easy to miss but can steadily reduce your system’s cooling ability over time.
- 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: These motors do a lot of heavy lifting—and can fail without warning. Inspections can help you avoid sudden loss of airflow.
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
- Your system turns on and off frequently (short cycling).
- Airflow that has become noticeably weaker.
- Rattling, banging, buzzing, and other strange noises.
- Leaks and excess moisture around your AC unit.
- Your home isn’t as comfortable as usual.
Even small issues can point to bigger trouble ahead, so it’s smart to act before they get worse.
