Seeing ice on your indoor coil, frost on the refrigerant line, or water where it should not be? In Baton Rouge’s humid climate, a freezing air conditioner is a warning sign—not something to “power through.” Running the system can worsen water damage, damage the compressor, and turn a manageable repair into a major one.
Let’s Geaux Refrigeration & HVAC provides residential AC repair across the Greater Baton Rouge area. Call 225-408-3774 or Request Service.
What to do first (in order)
1. Turn cooling off
Switch the thermostat to off or fan only (if your setup allows fan-only circulation without cooling—follow manufacturer guidance). The goal is to stop refrigerant migration and ice buildup while avoiding unnecessary strain.
2. Replace a dirty filter
A clogged filter is one of the fastest ways to drop airflow and freeze a coil. Use the correct size.
3. Open returns and supplies
Confirm nothing is blocking grilles. Collapsed flex duct in the attic can also starve the coil of air.
4. Do not chip ice
You can damage the coil fins. Let it thaw with airflow or natural melt—place towels if needed for drainage issues.
Why AC systems freeze (common causes)
- Low airflow: Dirty filter, stuck blower, bad capacitor, blocked duct
- Low refrigerant charge: Often indicates a leak that must be located and repaired
- Stuck metering device or TXV issues: Requires professional diagnosis
- Drain problems: Water backups can trigger safeties on some systems
What not to do
- Do not keep cooling on “to see if it fixes itself”
- Do not pour hot water on the coil
- Do not ignore water stains on ceilings near the air handler
When to call the same day
- Ice keeps returning after a filter change
- You hear hissing (possible leak) or electrical burning
- Water is leaking into drywall or insulation
