Common AC Issues We Identify
Hot summer months can put stress on even the most reliable AC systems. Our team is ready to step in, diagnose the issue, and get things working fast.
A few of the more common AC issues we come across include:
- Low Refrigerant Levels: Refrigerant doesn’t get used up—it leaks out. If levels are low, we’ll find the leak and either recharge the system or repair it, depending on severity.
- 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: Restricted filters force your system to work overtime, reducing performance and increasing the risk of future damage.
- Electrical Failures: Issues like bad wiring, failing capacitors, or tripped breakers can stop your AC from turning on or running properly.
- 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: If the condensate line gets clogged, it can cause water damage or shut down the system as a safety precaution.
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
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 O’Fallon AC 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: Tiny pinhole leaks can slowly reduce system efficiency, often going unnoticed until your home isn’t cooling properly.
- Sensor Malfunctions: Faulty sensors may misread temperature or airflow, causing improper cycling or inefficiency.
- Blower Motor Burnout: If the blower motor gives out, your system can’t circulate air. Maintenance reduces stress and helps spot early warning signs.
These problems often start small—but with regular maintenance, you can fix them before they turn into full-blown system failures.
Signs You Might Need AC Repair
- Short bursts of cooling instead of consistent operation.
- Noticeably reduced airflow from your registers.
- Unusual sounds—anything from buzzing to banging.
- Leaks or excess water collecting around the system.
- Your AC doesn’t seem to cool as well as it used to.
Whether it’s a quick adjustment or something more serious, catching these problems early saves time and money.
