Car AC & Heat Repair in St. George, LA
When the Louisiana weather swings from sizzling hot summers to chilly winter mornings, having a reliable air conditioning and heating system in your vehicle isn’t just a luxury — it’s a necessity. At L&S Automotive, we provide top-tier Car AC & Heat Repair in St. George, LA, near Baton Rouge, LA, that keeps your vehicle’s climate system running at its best. If you’ve noticed weak airflow, strange odors, or a cabin that just won’t get cool or warm enough, it’s time to bring your car in for a proper checkup.
Trusted Auto AC Repair Specialists
Your vehicle’s air conditioning system works hard in the southern heat. Our experienced technicians are trained to handle every aspect of car AC repair, from detecting leaks and inspecting compressors to replacing cabin filters and recharging refrigerant levels. Whether you need a quick auto AC recharge or a complete AC system rebuild, we have the knowledge and equipment to do the job right.
We work with R-134a and 1234yf refrigerants, ensuring your system is recharged with the correct fluid. Our diagnostics check pressure levels, condenser operation, evaporator function, and electrical connections so we can pinpoint the problem and provide a reliable fix.
We also inspect your AC belt, cooling fans, and compressor clutch engagement to rule out mechanical failures that could impact your system’s performance during those hot days.
Advanced Heating System Service
Don’t let cooler mornings catch you off guard. If your defroster isn’t clearing your windshield or your cabin never heats up, there’s likely a problem with your vehicle’s heater system. Our car heater repair services cover everything from thermostats and blower motors to heater cores and control valves.
Your car’s heating system uses the engine’s coolant to warm the air entering your cabin. If coolant levels are low or circulation is restricted, your heater won’t function properly. Our team performs complete auto heat service checks to ensure all components work as intended.
We also ensure your radiator functions correctly, as poor coolant circulation or clogged passages can impact heating and engine cooling performance.

Signs You Need AC or Heat Repair in St. George, LA
A failing air conditioner or heater usually doesn’t break all at once — the signs often build up slowly. Keep an eye out for these symptoms:
- AC blows warm air even on max cool setting
- The heater takes too long to warm up or blows cold
- Weak airflow through vents
- Unusual smells from vents (musty or sweet odor)
- Noisy fan or clicking sounds behind the dash
- Cabin fogging without effective defrosting
- Inconsistent temperature output between driver and passenger sides
- AC or heat cuts out after running for a while
- Dripping water under the dash from a clogged drain tube
- Dashboard climate controls become unresponsive
If you notice any of these, bring your vehicle in before the system gets worse — or more expensive.
The Role of the Heat Pump & Climate Control System
The heat pump system in modern vehicles helps control heating and cooling efficiency, especially in hybrid and electric cars. It allows for greater control over cabin temperature without putting excess strain on the engine. If your vehicle uses a heat pump and the system isn’t working properly, we have the tools and knowledge to service it correctly.
Advanced climate control systems rely on a network of sensors, actuators, and control modules. We provide complete diagnostics and repairs for dual-zone and automatic systems to ensure your preferred temperature stays consistent and comfortable.
We also update software modules and recalibrate climate sensors when required — something many general repair shops overlook.
Refrigerant Leak Detection and Recharge
Your AC system depends on the correct refrigerant charge to function correctly. However, small leaks in hoses, seals, or connections can cause refrigerant levels to drop over time. If your system is low, we’ll perform a vacuum test and recharge it using the proper refrigerant type for your vehicle.
We also use UV dye or electronic leak detection tools to find even the smallest leak, seal it, and prevent the issue from recurring. Skipping this step can result in recurring problems that prevent your AC from performing at full capacity.
We replace worn O-rings recharge service ports and inspect pressure switches to ensure long-lasting performance after the recharge.

HVAC System Maintenance Tips
- Change your cabin air filter every 12,000 to 15,000 miles

- Schedule yearly HVAC inspections before peak seasons
- Keep your cooling system flushed to prevent heater core blockages
