AC Systems We Service & Repair
Central Air Conditioning Systems
The most common residential cooling system, central AC cools your entire home through ductwork:
Components We Service:
- Outdoor condenser unit (compressor, fan, coils)
- Indoor evaporator coil and air handler
- Refrigerant lines
- Thermostat and controls
- Ductwork and vents
Common Central AC Problems:
- Not cooling or insufficient cooling
- System won’t turn on
- Freezing up (ice on coils or lines)
- Short cycling (turning on and off frequently)
- High energy bills
- Uneven cooling between rooms
Ductless Mini-Split Systems
Increasingly popular for their efficiency and zone control, mini-splits require specialized knowledge:
Why Ductless Systems Are Different:
- Individual indoor units for each zone
- Refrigerant lines instead of ductwork
- Advanced inverter technology
- Both heating and cooling capability
- Complex electronic controls
Common Mini-Split Issues:
- Remote control or communication errors
- Refrigerant line leaks
- Drainage problems
- Individual head unit failures
- Inverter board issues
Heat Pump Systems
Heat pumps provide both cooling and heating, making them work year-round:
Heat Pump Challenges:
- Reversing valve problems (affects heating and cooling)
- Defrost cycle issues
- More complex troubleshooting
- Harder-working compressors (year-round use)
Common Heat Pump Repairs:
- Reversing valve replacement
- Defrost control repairs
- Compressor failures (more common than AC-only units)
- Supplemental heat issues
Package Units & Split Systems
Different configurations, same expertise required:
Package Units: All components in one outdoor cabinet – common in commercial settings and some homes
Split Systems: Traditional setup with outdoor condenser and indoor air handler
We service both configurations with equal expertise.
Window & Portable AC Units
Don’t overlook smaller units – we repair these too:
- Window-mounted air conditioners
- Through-wall AC units
- Portable air conditioners with exhaust hoses
Common repairs: Compressor issues, fan motor replacement, thermostat problems, drainage clogs
Common AC Problems & Expert Solutions
AC Not Cooling or Blowing Warm Air
Could be a refrigerant leak, frozen evaporator coil, failed compressor, dirty condenser coils, or a faulty thermostat. Each one has a different fix — and guessing wastes money.
- We locate the actual cause before recommending any repair
- Refrigerant is never just “topped off” — we fix the leak first
- Dirty coils and airflow issues are often overlooked but easy to resolve
Dealing with warm air on a hot Lake Charles day? Charles Dependable Refrigeration will get to the bottom of it. Call 337-735-1063.
AC Won’t Turn On
Most common culprits are a tripped breaker, blown fuse, failed capacitor, bad contactor, or a wiring issue at the thermostat. We don’t just reset the breaker — we find out why it tripped.
Nothing happening when you adjust the thermostat? We can help. 337-735-1063
Refrigerant Leaks
Your AC never “uses up” refrigerant — if it’s low, there’s a leak. Signs include poor cooling, ice on the coil or lines, hissing sounds, and rising energy bills.
We find the leak, fix it, pressure test it, then recharge to manufacturer specs. If you have an older R-22 system, we’ll give you honest options on whether repair, retrofit, or replacement makes more sense.
Suspecting a refrigerant leak? Don’t let it sit — call Charles Dependable Refrigeration at 337-735-1063.
Compressor Issues
Symptoms include no cooling, loud grinding or clicking from the outdoor unit, or a repeatedly tripping breaker. The compressor is expensive — we test everything thoroughly before recommending replacement.
- Under 10 years old or under warranty? Repair usually makes sense.
- 12+ years old, multiple past repairs, or R-22 system? Replacement is often the smarter call.
Hearing something off from your outdoor unit? Let’s take a look. 337-735-1063.
AC Freezing Up
Ice on your coil or lines isn’t normal. It’s usually caused by a dirty filter, blocked vents, a failing blower motor, or low refrigerant.
We don’t just thaw it out — we find and fix what caused it in the first place.
Is your indoor unit icing over? Charles Dependable Refrigeration can sort it out. 337-735-1063.
Short Cycling
If your AC runs for only a few minutes before shutting off and restarting, it’s short cycling, costing you in energy and component wear. Common causes are an oversized system, dirty filter, refrigerant issues, or a worn contactor.
AC turning on and off too often? That’s not normal. Call us at 337-735-1063.
High Energy Bills
Dirty coils, a clogged filter, low refrigerant, aging equipment, or leaky ducts can all cause your AC to work harder than it should. Systems over 10 years old can cost 30–50% more to run than newer ones.
Cooling bills creeping up every month? We can assess your system and give you straight answers.
Unusual Noises
- Grinding or banging — shut the unit off and call immediately
- Clicking — usually a failing capacitor or contactor
- Hissing — possible refrigerant leak
- Buzzing — electrical issue or loose component
- Squealing — worn motor bearings
Hearing something that doesn’t sound right? Charles Dependable Refrigeration serves Lake Charles and the surrounding area. 337-735-1063.
Thermostat Problems
A blank display, incorrect temperature readings, or an AC that won’t respond are all signs your thermostat may be the issue — not the AC itself. We test, calibrate, or replace as needed, and can install smart thermostats like Nest or Ecobee if you want more control.
Think your thermostat is acting up? It’s worth a quick check. 337-735-1063
Ductwork Issues
Leaky or damaged ducts can quietly waste 20–30% of your cooled air before it ever reaches a room. Signs include rooms that never cool evenly, high bills despite a working AC, and dusty or stale air.
Some rooms just never feel cool enough? The problem might be in the ducts. Charles Dependable Refrigeration can find out. 337-735-1063
