Here are the top 5 reasons your AC might not be doing its job—and what to do about it:
1. Dirty or Clogged Air Filter
How often should you clean or change your air conditioner's air filter?
Every 30–60 Days (Especially in Lake Charles Humidity)
This is super important to get correct because restricted airflow from a dirty air filter can reduce cooling by up to 15%,, according to the U.S. Department of Energy.

Pro Tip: Set a reminder to replace your filter monthly during peak summer use in Louisiana.
2. Low Refrigerant (It’s Leaking—Not Just “Low”)
Refrigerant doesn’t “run out”—if it’s low, it’s leaking. Signs include:
- Ice on the lines
- Hissing or bubbling sounds
- Lukewarm air from vents
Leaks can damage your compressor and lead to full system failure. This isn’t a DIY fix—call an EPA-certified HVAC tech like our team at S&S.
3. Thermostat Issues or Settings Error
Before calling in the cavalry, check:
- Is it set to “Cool”?
- Are the batteries fresh?
- Is the set temp lower than the room temp?
Still no go? It could be a wiring or sensor issue needing professional diagnosis.
4. Dirty Outdoor Unit or Blocked Condenser
Lake Charles pollen, dirt, and storm debris often clog outdoor coils, restricting heat dissipation. If your AC is struggling to cool, inspect the unit:
- Clear away leaves and buildup
- Ensure at least 2 feet of clearance around the unit
Still struggling? It may need a deep clean from a pro.
5. Electrical or Mechanical Failures
Burned-out capacitors, failed compressors, or damaged motors can leave your system unresponsive—or short-cycling. If your AC:
- Clicks but doesn’t start
- Starts then shuts off quickly
You need a technician with diagnostic tools to fix it safely and correctly.
