What to Do When Your Air Conditioner Stops Working Suddenly
Hiring a qualified air conditioning contractor can make the difference between a quick fix and a costly recurring problem in your home. This guide covers what to do when your AC stops working, how to troubleshoot before calling a professional, and what to look for when choosing an air conditioning contractor serving Banner Elk, NC.
What to Do When Your Air Conditioner Stops Working Suddenly
A sudden AC failure often has a simple cause you can check yourself. Before assuming the worst, walk through these quick steps.
Quick Troubleshooting Checklist:
- Check your thermostat settings and make sure it is set to "cool," not "heat" or "fan only."
- Replace or inspect the air filter, since a clogged filter can cut off airflow and cause the system to shut down.
- Check your circuit breaker panel for a tripped breaker tied to your HVAC unit.
- Look at the outdoor unit to see if ice has built up around the coils, which may signal a refrigerant or airflow issue.
- Make sure all supply and return vents in your home are open and unblocked.
If none of these steps restores cooling, the issue may be mechanical. At that point, contacting a licensed air conditioning contractor is the right move.
When Should You Call an Air Conditioning Repair Contractor?
Some AC problems go beyond basic troubleshooting. Call a professional when you notice any of the following:
- The system runs constantly but never cools your home below a set temperature.
- You hear grinding, banging, or squealing sounds coming from the unit.
- You notice warm air blowing from vents despite correct thermostat settings.
- Water is pooling around your indoor air handler or leaking onto floors.
- Your energy bills have risen sharply without a change in usage habits.
These symptoms can point to refrigerant leaks, failed compressors, or electrical faults. A certified air conditioning repair contractor can diagnose and resolve these issues safely.
