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 come across 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: Poor airflow or low refrigerant can cause your coils to freeze, reducing your system’s ability to cool the air.
- Dirty or Clogged Filters: Restricted filters force your system to work overtime, reducing performance and increasing the risk of future damage.
- Electrical Failures: Worn electrical components or tripped breakers often cause sudden cooling loss or total system shutdowns.
- Thermostat Problems: If your thermostat is faulty, your AC won’t know when—or how long—to run. A quick fix or replacement may solve everything.
- Drainage Issues: A clogged condensate line can trigger safety shut-offs or lead to water damage around your system.
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
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 Earth City AC 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: Small leaks in the refrigerant line can quietly drain performance—often going undetected until your AC stops cooling effectively.
- Sensor Malfunctions: Faulty sensors may misread temperature or airflow, causing improper cycling or inefficiency.
- 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.
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
- AC kicks on and off too often without running long enough.
- Less airflow through your ducts and vents.
- Strange or loud operational noises you haven’t heard before.
- Drips, puddles, or moisture near the air conditioner.
- It’s harder to keep your home comfortable like you used to.
Whether it’s a quick adjustment or something more serious, catching these problems early saves time and money.
